You are paying too much for a traditional stick-built home. The lumber is overpriced, the timeline stretches to 18 months, and half the contractors do not show up when they say they will.
This guide covers everything from what a barndominium actually is to how much it costs, how construction works, and how Metal America helps you through the entire process. No fluff, no corporate nonsense. Just the facts you need to make a smart decision about your next home.
What Is a Barndominium?
A barndominium is a metal building structure with 12-gauge steel framing and 26-gauge panels designed as a residential living space. It combines the open layout and durability of a barn with all the comfort and features of a traditional home. The name comes from “barn” plus “condominium,” though these buildings have nothing to do with shared ownership or apartment living.
The construction uses commercial-grade metal building components. The primary framing consists of 12-gauge galvanized square tubing spaced 4 feet on center. The exterior uses 26-gauge metal panels in your choice of colors. Buildings 30 feet wide or less use double legs for additional support. Buildings over 30 feet wide require ladder legs, 1-foot-wide support structures that span the extra width.
Traditional stick-built homes rely on wooden 2×4 or 2×6 studs. Barndominiums use steel that will not rot, warp, or attract termites. The metal shell goes up fast, weather-tight in days instead of weeks. Then you finish the interior just like any other home with insulation, drywall, plumbing, and electrical work. If you wanted, you could even still add wood framing.
People call these structures “shop houses” or “metal homes” in some parts of the country. The concept started with farmers converting existing pole barns into living quarters. Now, purpose-built barndominiums serve as primary residences, short-term rentals, or combined home and workshop spaces.
Barndominium vs Traditional Home
| Feature | Barndominium | Traditional Home |
|---|---|---|
| Construction Time | 9-12 months average | 12-18 months average |
| Base Cost per Sq Ft | Shell at $15-25/sq ft, total $100-150/sq ft | $150-250+/sq ft depending on market |
| Customization Flexibility | Extremely high, open floor plan allows any layout | Limited by load-bearing walls |
| Durability | 20-year rust warranty on frame, weather-resistant | Vulnerable to rot, termites, weather damage |
| Maintenance | Minimal, metal exterior requires little upkeep | Regular painting, siding repair, pest treatment |
| Energy Efficiency | Highly efficient with proper insulation | Vulnerable to rot, termites, and weather damage |
The main difference shows up in how you build. Traditional construction requires framing each wall individually, installing roof trusses piece by piece, and sheathing everything with plywood before adding siding. A barndominium shell arrives as a complete engineered system. The manufacturer delivers pre-cut components that bolt together in a matter of days.
You still need a concrete foundation. You still need permits and inspections. You still hire electricians, plumbers, and HVAC contractors. The difference is that you start with a superior structure that goes up faster and costs less.
Why Choose a Barndominium Over Traditional Construction?
Barndominiums save you money and time compared to traditional construction. The metal shell typically costs $15 to $25 per square foot installed. A comparable stick-built structure costs $40 to $60 per square foot for basic framing and exterior work. That difference adds up fast on a 2,000-square-foot home.
Construction speed matters when you are paying rent somewhere else. A traditional home takes 12 to 18 months from breaking ground to moving in. A barndominium shell goes up in weeks, and the entire project finishes in 9 to 12 months on average. You will be living in your new home soon.
The open floor plan gives you design flexibility that traditional homes cannot match. There are no load-bearing interior walls to work around. You can put your kitchen wherever you want. You can create a massive great room or divide the space into smaller areas.
Metal buildings handle Southern weather better than wood construction. The 12-gauge steel frame is rated for 140 mph winds. The building sits through hurricanes that tear traditional homes apart. Tornadoes can still cause damage, but the metal structure holds together better than wood framing that snaps and splinters.
Maintenance costs drop significantly over time. The metal exterior does not rot, so you never replace siding. Termites cannot eat steel. You might need to touch up scratched paint every few years, but that beats re-painting an entire house or replacing warped boards.
Property values benefit from the durability and low maintenance. A well-built barndominium can increase property value by 5% to 10% compared to raw land. Buyers appreciate the combination of open space, workshop potential, and modern living areas.
Top 5 Practical Advantages
Construction timeline averages 9-12 months total compared to 12-18 months for traditional homes, saving you rent and getting you into your home faster
Weather resistance includes a 140 mph wind rating and a 25-35 PSF snow load capacity, depending on the manufacturer, protecting your investment from Southern storms
Open floor plan flexibility allows any interior layout without structural constraints, making it easy to customize for your exact needs
Lower maintenance requirements mean no painting siding, no termite treatments, and no rot repairs over the building’s lifetime
Property value considerations show 5% to 10% increases for well-built barndominiums compared to vacant land values
Construction Timeline Comparison
| Phase | Barndominium Timeline | Traditional Home Timeline |
|---|---|---|
| Foundation | 2-3 weeks | 2-3 weeks |
| Framing/Shell | 1-2 weeks for shell installation | 4-8 weeks for complete framing |
| Interior Finish | 6-7 months | 8-12 months |
| Total | 9-12 months average | 12-18 months average |
The numbers tell the story. You save money upfront on the shell. You save time during construction. You save money long-term on maintenance. The only real downside is that some people do not like the aesthetic of metal buildings. That is fine. Buy a traditional home and pay double.

Barndominium Floor Plans and Design Options
Barndominiums range in size from 1,200 to over 5,000 square feet. The most popular sizes range from 1,800 to 3,000 square feet. This range gives you enough space for comfortable living without paying for square footage you do not need.
Single-story layouts work best for most families. You get easy access to everything, no stairs to climb, and simpler construction. Two-story designs are possible but require additional structural planning and cost more to build. The second floor needs proper support from interior framing, not the exterior metal columns.
The typical layout features living space on one side and a garage or workshop on the other. A 40×60 building might have 1,200 square feet of finished living area and 1,200 square feet of shop space. This arrangement gives you the best of both worlds without having to build two separate structures.
Bedroom and bathroom configurations depend on your family size and future plans. A 2-bedroom, 2-bathroom layout works for couples or small families. A 3-bedroom, 2.5-bathroom design accommodates larger families. Some people plan 4 bedrooms to have a dedicated office space or guest rooms. Every barndominium needs at least 2 exit doors to meet code requirements.
Kitchen layouts benefit from the open floor plan. Most barndominiums use an open-concept layout, with the kitchen flowing into the dining area and great room. This design makes the space feel larger and works well for entertaining. You can put an island wherever it makes sense without worrying about load-bearing walls.
Popular Barndominium Floor Plan Sizes
| Size | Typical Layout | Best For | Est. Shell Cost Range |
|---|---|---|---|
| 1,200-1,500 sq ft | 2bd/2ba, single story | Singles, couples, small families | $18,000-$37,500 |
| 1,800-2,400 sq ft | 3bd/2ba, single story | Average families, need some space | $27,000-$60,000 |
| 2,500-3,500 sq ft | 3-4bd/2.5-3ba, single or two-story | Larger families, want workshop space | $37,500-$87,500 |
| 4,000+ sq ft | 4+ bd/3+ ba, often includes shop | Large families, serious workshop needs | Average families need some space |
Second-story options add complexity but maximize your footprint. You need to account for staircase space, which takes about 40-50 square feet. Bedrooms upstairs must have proper egress windows for fire safety. The window sill height cannot exceed 44 inches from the finished floor to meet code requirements.
An attached versus a detached garage comes down to preference and budget. An attached shop or garage under the same roofline costs less than building a separate structure. You also have the convenience of walking directly from your living space to your vehicles or workshop. Detached garages offer better noise separation and keep vehicle fumes away from living areas.
Design Considerations
- Living space vs garage/shop space ratio depends on whether you need more living area or workshop space, with most people choosing 50/50 or 60/40 living to shop
- Bedroom/bathroom count should account for current needs plus future growth, resale value, or guest accommodations
- Kitchen layout options work best as an open concept in barndominiums, taking advantage of the wide-open floor plan
- Second-story considerations add cost and complexity but maximize usable space on smaller lots
- Attached vs detached garage affects convenience and cost, with attached being cheaper and detached providing better separation
Width constraints matter for planning. Metal buildings are priced in 2-foot width increments. A 28-foot-wide building costs the same as a 29-foot-wide building. Buildings over 30 feet wide require commercial-grade trusses and ladder legs, which significantly increase costs. Most barndominium customers stay at 30 feet wide or less to avoid that price jump.
Length is more flexible. For buildings 30 feet wide or under, pricing is in 5-foot increments. A 42-foot-long building costs the same as a 45-foot-long building. For buildings 32 feet wide and wider, length pricing uses 2-foot increments. There is no maximum length, though transportation becomes more difficult for extremely long buildings.
Height determines how much vertical space you have for second stories or tall workshop areas. Standard heights range from 9 to 12 feet for single-story designs. Two-story barndominiums often use 12-foot ceilings on the first floor to accommodate proper second-floor framing.
Barndominium Construction Process Step by Step
Building a barndominium takes 9 to 12 months on average from start to finish. This timeline includes everything from initial planning to final inspections and move-in. Understanding each phase helps you know what to expect and when you need to make decisions.
The process breaks down into 13 distinct phases. Each phase builds on the previous work. Trying to skip steps or rush through critical planning stages results in costly mistakes and delays.
The 13 Construction Phases
- Design & Planning – Select floor plan, determine loan type, research permit requirements
- Engineered Drawings & Permits – Obtain required plans and submit for permits
- Site Preparation – Clear land, grade for drainage, mark utility lines
- Foundation & Slab Construction – Pour concrete with proper footings and drip ledge
- Metal Shell Installation – Metal America delivers and installs a complete shell
- Post-Shell Construction – Add base rail sealant and weatherproofing
- Interior Framing Solutions – Frame interior walls around ladder legs if over 30′ wide
- Insulation Installation – Apply a closed-cell and open-cell foam system
- Cathedral Ceilings – Frame and finish any cathedral ceiling areas (if applicable)
- MEP Installation – Install mechanical, electrical, and plumbing systems
- Final Weatherproofing & Sealing – Complete all exterior sealing work
- Final Inspection & Testing – Pass all required inspections
- Finishing Touches & Handoff – Complete landscaping, final cleanup, customer orientation
Phase 1 – Design & Planning
Design and planning determine everything that comes after. You need to know exactly what you want to build before you order materials or break ground. This phase takes 2 to 4 weeks for most customers.
Start by determining your loan type. Construction loans, personal loans, and HELOCs all have different requirements. Construction loans require a general contractor. Personal loans and HELOCs give you more flexibility. Your financing affects your timeline and who you can hire.
Research your local permit requirements next. Call your county building department if you live outside city limits. Call your city building department if you live inside city limits. Ask specifically what documentation they require for a residential metal building under 5,000 square feet.
Site selection matters more than people realize. You need relatively flat land or budget for grading costs. You need access for concrete trucks and delivery vehicles. You need to know where utilities connect. Drive by the property during the rain to see how water drains. The lot needs to be level within 3 inches front-to-back and side-to-side before shell installation.
Phase 2 – Engineered Drawings & Permits
Engineered drawings are required before you can pour concrete. The type of drawings you need depends on your location and local building department requirements. This is critical because many customers waste time and money ordering the wrong drawings.
There are three types of drawings to understand clearly.
Generic engineered drawings are pre-designed plans that manufacturers provide free or for a maximum of $300-$400. These work for rural properties with no permit requirements. They have preset limitations and do not include site-specific structural calculations. You cannot use these for most permitted projects.
Site-specific engineered drawings are custom plans tailored to your exact location, soil type, climate, and local building codes. These include detailed structural calculations signed by a licensed engineer. Site-specific drawings cost $1.40 to $1.80 per square foot, depending on your PSF (pounds per square foot) requirements.
Full house plans are complete sets that include structural, mechanical, electrical, plumbing, and foundation drawings, as well as floor plans. You only need these if your building department specifically requires them or if you want complete documentation for your general contractor and subcontractors. Full plans cost significantly more than site-specific structural drawings alone.
When Different Drawings Are Required
| Property Type | Minimum Required | Recommended | Why |
|---|---|---|---|
| Rural/no permits | None technically | Generic drawings | Cost savings, manufacturer provides free |
| Homes under 5,000 sq ft with county/city requirements | Site-specific structural drawings | Site-specific structural drawings | 99.5% of permitted projects, satisfies building department |
| Complete project scope | Site-specific structural drawings | Full house plans | Eliminates confusion for all contractors, reduces change orders |
The 99.5% rule is important to understand. For homes under 5,000 square feet, building departments typically require only structural engineered drawings. You do not need an architect. You do not need full architectural plans. Structural drawings become the primary technical requirement for your permit.
Site-specific drawing pricing breaks down by PSF requirements. A building designed for 35 PSF costs $1.40 per square foot for drawings. A building designed for 65 PSF costs $1.60 per square foot. A building designed for 90 PSF costs $1.80 per square foot. Higher snow loads require stronger designs and more engineering time.
Contact your building department to determine your PSF requirement. They base this on your geographic location and local weather history. Do not guess. A building engineered for 35 PSF will not pass inspection in an area that requires 65 PSF.
Metal America connects you with trusted engineering firms that understand metal building requirements.
Phase 3 – Site Preparation
Site preparation sets the foundation for a successful build. Clear and grade the site for proper drainage away from the slab. Evaluate soil bearing capacity with a target of at least 1500 PSF. Replace or compact poor soils to prevent settling.
Ensure backfill is well-compacted under all slab areas. Grade the surrounding soil to slope away with a 6-inch drop over the first 10 feet from the building. Mark any utility lines and have overhanging power lines moved if necessary.
The lot must be level within 3 inches front-to-back and side-to-side before shell installation. If the crew arrives and your lot is not level, they will leave. You will pay a $500 return charge when the site is ready.
You need a minimum of 10 feet of clearance around the entire building for the lift and installation crew. Trees, fences, or other structures within that clearance zone cause problems and slow installation.
Phase 4 – Foundation & Slab Construction
The foundation might be the most critical phase of your entire project. You cannot fix foundation mistakes after the building goes up. Take your time and do it right.
The recommended foundation for barndominiums is a notched edge slab, also called a drip ledge. This design includes a 3- to 5-inch perimeter ledge that drops 3/4 to 1-1/2 inches below the main slab surface. The notch lets your metal panels extend past the concrete, preventing water from sneaking under the base rails.
Standard concrete specifications call for a minimum 4-inch thick slab, with 6-inch thickness recommended for two-story buildings. Use 3000 PSI concrete minimum. Reinforce with #3 rebar in the slab and #4 rebar in the footers. The rebar grid should be spaced 18 inches on center.
Footers go around the entire perimeter. Standard sizing is 12 inches wide by 12 inches deep, though local codes might require different dimensions. Footer depth must extend below your local frost line. This varies from 12 inches in warm climates to 48 inches or more in cold regions where ground freezes deep in winter.
Install all underslab plumbing before pouring concrete. This is absolutely critical. You cannot add plumbing under a slab after it cures. You would have to core drill through 4 to 6 inches of reinforced concrete, which is expensive and creates a weak point.
Run water supply lines for every bathroom, kitchen, laundry room, and outdoor spigot. Run drain lines for every sink, shower, tub, and toilet. Install conduit for any electrical that needs to run under the slab. Stub everything up above the finished slab height and cap it. Test your water lines under pressure before the pour.
Critical note on base rails and rough-ins: All Metal America buildings have double or ladder base rails. This means any plumbing or electrical running through the slab must be positioned far enough inboard to clear both base rail layers. Account for this during your underslab rough-in or you will have major problems when the building arrives.
Have the underslab plumbing inspected prior to pour. Once the concrete is poured, contact Metal America to proceed with building manufacturing.
Phase 5 – Metal America Shell Installation
Metal America manufactures, delivers, and installs your complete shell. This is what you are paying us for. We handle the entire process from fabrication to final bolt tightening.
The shell package includes the following components. The 12-gauge galvanized square tube steel frame comes with a 20-year rust warranty. You get double legs for buildings 30 feet wide and under or ladder legs for buildings over 30 feet wide. All uprights space 4 feet on center for proper load distribution.
Complete roof and wall panels in 26-gauge minimum thickness come in your chosen colors. We install double-bubble insulation on every barndominium at no extra charge. This insulation redirects 96% of radiant heat and acts as a vapor barrier.
Frame-outs for all doors and windows get cut during fabrication. We build these to your specifications based on the rough opening sizes you provide. Getting these measurements right matters because adjusting frame-outs after installation is expensive. All frame-outs include header bars which take up space and must be accounted for in your planning.
All necessary trim and weatherproofing are included in the package. This includes ridge caps, corner trim, eave trim, and J-trim around openings. We also provide base rail sealant that creates a watertight seal between the base rails and your concrete.
Installation typically takes 2 to 3 days, depending on the building’s size and the weather. The crew bolts the base rails to your concrete using expansion anchors. They erect the columns and ladder legs, then attach the roof trusses. Finally, they install all panels, trim, and seal everything properly.
Door and window installation: Metal America can install your doors and windows during shell installation for $200 per unit. The doors and windows must be on site before sheeting installation for structural integrity. If you do not have them ready, you will need to hire someone else to install them after the shell is up, which costs more time and money.
Payment is due upon completion of installation. We do not take the final payment until you walk around the building and verify everything looks correct. If you plan to pay by credit card, ACH, or wire transfer, notify the office when installation is scheduled so we can make arrangements.
Phase 6 – Post-Shell Construction
After shell installation, apply base rail sealant if not already done. This creates a watertight seal between the base rails and concrete, preventing water seepage, wind, dust, and debris from entering under the base rails.
If doors and windows were not installed during shell construction, you handle that work. Confirm header bar size and placement, mark rough openings for window flanges and trim, and install jamb studs and sill bars if needed.
Phase 7 – Interior Framing Solutions for Buildings Over 30 Feet Wide
Buildings over 30 feet wide use ladder legs or commercial trusses with web bracing. These structural elements intrude about 12 inches into your interior space on both walls. You have two options for handling this intrusion.
Option A – Offset Stud Wall gives you the best insulation and the most traditional interior finish. You frame a standard 2×4 stud wall 12 inches inboard from the steel panels. This creates a full-depth cavity for insulation and space for electrical and plumbing runs. You lose 12 inches of floor width on each side, so a 40-foot-wide building gives you about 38 feet of usable interior width.
Build the offset wall by placing a pressure-treated 2×4 bottom plate on the slab. Anchor it with concrete fasteners spaced 24 inches on center. Install vertical 2×4 studs at 16 inches on center. Attach a top plate to the steel frame using clip angles or blocking between the ladder leg members.
The stud cavity provides space for wiring, plumbing, and full insulation. You attach drywall to the studs just like a normal house. The downside is the material cost and the foot of space you lose on each wall.
Option B – Hat Channel Detail minimizes space loss. You run 7/8-inch or 1-inch metal hat channels vertically or horizontally, spaced 16 inches on center. Screw the channels directly to the steel frame. Where channels cross ladder legs, use a 1-1/2-inch hat channel or stack strips to maintain a consistent depth. Attach drywall directly to the hat channels.
This method only loses about 1 inch of width on each side. A 40-foot-wide building gives you roughly 39 feet 10 inches of usable width. The trade-off is no cavity for conventional wiring or plumbing. You must use surface-mount electrical conduit and run plumbing through interior partition walls only.
Most customers who choose full interior finishes opt for offset stud walls, even though they lose space. The ability to run wiring and plumbing normally outweighs the extra cost and square footage loss.
Phase 8 – Insulation Installation
Double-bubble insulation is included on every Metal America build, but additional insulation is required for habitable structures. The most effective approach uses a closed-cell and open-cell foam system.
Step 1 – Closed-Cell Foam Application: Apply 1 to 2 inches of closed-cell foam directly on metal panels for moisture control. This provides R-6 to R-7 per inch and acts as a vapor barrier when 2 inches or thicker.
Step 2 – Open-Cell Foam Application: Add 3 to 5 inches of open-cell foam for additional insulation value. This provides R-3.5 to R-4 per inch and fills the remaining cavity space.
This combined approach typically achieves R-20 to R-30 for walls and R-30 to R-40 for ceilings, meeting most energy code requirements while providing excellent moisture control.
Phase 9 – Cathedral Ceilings
If your design includes cathedral ceilings, frame and finish these areas in accordance with your floor plan. Cathedral ceilings add height and drama to living spaces, but require proper planning for insulation and ventilation.
Phase 10 – Mechanical, Electrical, and Plumbing
MEP installation is where your barndominium starts feeling like a real home. This phase typically takes 6 to 8 weeks, depending on complexity and contractor availability.
Start with HVAC because ductwork affects everything else. Forced-air systems require a mechanical room or closet for the furnace and air handler. Plan 100 to 200 square feet for this space. Run supply and return ducts through interior soffits or furred-down ceiling chases.
Ductless mini-split systems work great in barndominiums. Mount wall units in your main living areas. Put separate heads in bedrooms. These systems require less space than traditional ductwork and cost less to install. The outdoor condenser goes on a pad next to the building.
Plumbing must stay inside a conditioned space to prevent freezing. This is especially important in metal buildings where exterior walls have no insulation cavity. Group bathrooms and kitchens back-to-back when possible to minimize plumbing runs. Use PEX tubing for supply lines because it handles the tight spaces better than copper.
Water heater location depends on fuel type. Tank heaters go in utility rooms or garages. Tankless units can mount on exterior walls if you buy exterior-rated models. Any wall penetrations need proper flashing and sealing.
Electrical service enters through a main panel mounted on a structurally sound surface. You might need to attach plywood backing to a steel column to provide a solid mounting surface. Run NM cable through the stud walls if you built offset walls. Use MC cable or EMT conduit for the hat channel areas where you have no wall cavity.
Grounding is critical in metal buildings. Connect your steel frame to the panel grounding bus using #4 or #6 copper wire. Install a grounding electrode system per code, typically ground rods driven 8 feet into soil or a Ufer ground in your concrete. Bond all metal pipes, including water and gas lines, to the grounding system. Proper grounding is essential for safety in metal structures.
Phase 11 – Final Weatherproofing & Sealing
Complete all exterior sealing work. Install gutter downspout extensions or splash blocks 3 to 5 feet from the slab. Final grade soil to slope away from the building. Install any porch or lean-to attachments with proper flashing.
For pest prevention, stuff steel wool in small gaps at eaves or around penetrations. Use expandable foam with rodent-resistant properties. Verify garage doors and thresholds are well-sealed.
Phase 12 – Final Inspection & Testing
Pass all required inspections, including building, electrical, plumbing, and mechanical permits. Schedule each inspection when the required work is complete. Do not cover up work that needs inspection.
Critical success factors include achieving zero leaks throughout the build, ensuring proper grounding of the metal structure, and confirming that all work meets local codes and engineering specifications.
Phase 13 – Finishing Touches & Handoff
Complete landscaping, final cleanup, and customer orientation. Provide the customer with a Certificate of Occupancy, all warranty information, including 20-year rust warranty documentation from Metal America, maintenance manuals for installed systems, and contact information for future service needs.
Instruct the homeowner on Metal America building maintenance including inspecting the roof annually for backed-out screws or aging sealant, checking after major storms, touching up scratches immediately to prevent rust, and never drilling holes in exterior steel without proper sealants.
Barndominium Costs and Pricing Breakdown
Barndominium total costs range from $100 to $150 per square foot for a complete, move-in-ready home. This breaks down into shell cost, foundation, drawings, and interior finish. Understanding each component helps you budget accurately.
The metal shell from Metal America typically costs $15 to $25 per square foot installed. This includes the complete structural package with 12-gauge framing, 26-gauge panels, double-bubble insulation, frame-outs, trim, and professional installation. Shell cost varies by building size, your location, and the current manufacturer pricing.
Foundation and concrete work add $6 to $14 per square foot, depending on your area. Northern states with deeper frost requirements cost more. Areas with difficult soil conditions cost more. Simple jobs on flat land with good soil cost less. The slab includes perimeter footers, rebar reinforcement, and concrete.
Site-specific engineered drawings cost $1.40 to $1.80 per square foot, depending on PSF requirements. A 2,400-square-foot building designed for 35 PSF costs about $3,360 for drawings. The same building, designed for 90 PSF, costs about $4,320. These drawings are required for 99.5% of permitted projects.
Interior finish is where costs vary wildly. A basic finish with standard materials might cost $40 to $60 per square foot. This includes drywall, flooring, cabinets, fixtures, and paint. An upgraded finish with custom features runs $60 to $90 per square foot or more.
MEP systems (mechanical, electrical, plumbing) typically cost $15 to $25 per square foot combined. This covers HVAC installation, complete electrical service and wiring, plumbing supply and drain lines, and basic fixtures.
Barndominium Cost Breakdown by Component
| Component | Cost Range | Notes |
|---|---|---|
| Metal shell | $15-$25/sq ft | From Metal America, includes installation |
| Foundation/concrete | $6-$14/sq ft | Varies significantly by location and soil |
| Site-specific drawings | $1.40-$1.80/sq ft | Based on PSF requirements (35-90 PSF) |
| Interior finish | $40-$90/sq ft | Wide range based on material quality |
| MEP systems | $15-$25/sq ft | Mechanical, electrical, plumbing combined |
| Total estimated cost | $100-$150+/sq ft | Complete move-in-ready project |
Location affects pricing more than people expect. Concrete costs $8 per square foot in rural Texas but $12 per square foot in Colorado. Labor rates vary by region. Material delivery costs more to remote areas. Always get local quotes rather than relying on national averages.
Sample Barndominium Project Costs
| Size | Shell Cost | Total Project Cost | Cost per Sq Ft |
|---|---|---|---|
| 1,500 sq ft | $22,500-$37,500 | $150,000-$225,000 | $100-$150 |
| 2,400 sq ft | $36,000-$60,000 | $240,000-$360,000 | $100-$150 |
| 3,000 sq ft | $45,000-$75,000 | $300,000-$450,000 | $100-$150 |
Building size affects price per square foot. Smaller buildings cost more per square foot because fixed costs (permits, site prep, engineering) spread across less square footage. Larger buildings achieve better economies of scale. A 3,000-square-foot barndominium typically costs less per square foot than a 1,500-square-foot barndominium.
What Affects Barndominium Pricing
Building size determines base cost, with width increments priced every 2 feet and length increments every 5 feet for buildings 30′ wide and under
Location creates significant price variation, with concrete ranging from $6 to $14 per square foot, depending onthe region
PSF requirements affect drawing costs, with 35 PSF costing $1.40/sq ft versus 90 PSF costing $1.80/sq ft for engineering
Interior finish level ranges from basic ($40-60/sq ft) to upgraded ($60-90+/sq ft), depending on materials and features
Site preparation needs add cost for clearing, grading, or dealing with difficult soil conditions
Width increments affect pricing structure. Metal buildings are priced in 2-foot width increments. A 28-foot-wide building costs the same as a 29-foot-wide building. Go up to 30 feet wide, and you stay in the same price bracket. Jump to 32 feet wide, and you need commercial trusses, which significantly increase the cost.
Length pricing uses 5-foot increments for buildings 30 feet wide and under. A 42-foot-long building costs the same as a 45-foot-long building. For buildings 32 feet wide and up, length pricing uses 2-foot increments instead.
Financing Your Barndominium
Financing a barndominium requires understanding your options and their requirements. Three main paths exist for most buyers. Each has different credit requirements, terms, and documentation needs.
Traditional construction loans work like standard mortgages but release funds in stages as construction progresses. You need a credit score of 690 or better. Terms typically run 5 to 10 years. Interest rates average 6% to 12%, depending on market conditions and your credit.
Documentation requirements include bank statements, pay stubs or tax returns, property information, building plans, and general contractor information. Note that all construction loans require a licensed general contractor. You cannot act as your own GC and get a construction loan.
In-house financing comes from some manufacturers. These are portfolio loans that the company holds itself. They might offer terms like zero down and 10% interest. Credit score requirements typically stay around 650 minimum. The benefit is simplified approval through one company. The downside is less flexibility and often higher rates than you get by shopping around.
Barndominium Financing Options
| Option | Credit Required | Terms | Best For |
|---|---|---|---|
| Traditional/construction loan | 690+ | 5-10 years | Strong credit, want lowest rates |
| In-house financing | 650+ | Varies | Simplified approval through one company |
Cash buyers avoid financing hassles entirely. If you have the money saved, you control the timeline and avoid paying interest. You can also move at your own pace without lender inspections or draw schedules. Many barndominium buyers use a combination of cash plus a smaller loan to minimize interest costs.
Home equity loans or HELOCs work if you own property with equity. You borrow against your existing home to finance the barndominium. Rates typically beat construction loans. You also avoid the general contractor requirement since you are not getting a construction-specific loan. This gives you the flexibility to act as your own GC if you have the skills.
Required documentation varies by lender but generally includes proof of income, bank statements showing reserves, property appraisal, building plans, and cost breakdown, and proof of homeowners’ insurance.
General contractor requirement applies to virtually all construction loans. The lender wants a licensed professional managing the project. This protects their investment. You can hire a GC to oversee the project while you do some work yourself, but the GC holds the license and takes legal responsibility.
Q: Can I finance a barndominium?
A: Yes, barndominiums can be financed through traditional construction loans (690+ credit), in-house financing, or rent-to-own options, but most construction loans require a general contractor.
Barndominium Permits and Code Compliance
Permits are your responsibility as the property owner. Metal America does not pull permits for you. Understanding this requirement upfront prevents delays and frustration.
Most locations require building permits for habitable structures. Rural properties sometimes have no permit requirements, but most counties and all cities require permits for any building you will live in. Call your local building department to confirm requirements before ordering anything.
Research your permit requirements by following this process. First, identify the correct authority. If you live inside city limits, contact the city building department. If you live outside city limits, contact the county building department. Search online for “[City/County name] building permit and zoning department” to find contact information.
Call and ask specific questions about metal building residential structures. Say, “I am planning to install a [size] metal building barndominium at [address]. What engineering or site plan documentation do you require for a building permit?” Write down exactly what they tell you.
Most building departments require site-specific structural engineered drawings for homes under 5,000 square feet. You do not need full architectural plans unless the building department specifically requires them. The structural drawings showing how the building safely supports loads typically satisfy permit requirements for residential structures in this size range.
Some jurisdictions require plans submission before you can order the building. Others let you order first and submit plans later. Know which process your building department follows. Ordering a building before confirming permit requirements can leave you with an expensive structure you cannot legally install.
How to Research Permit Requirements
Identify the correct authority by determining if your property falls inside city limits (city department) or outside city limits (county department)
Search online for “[City/County] building permit and zoning” to find contact information and requirements
Call and ask specific questions, such as “What engineering documentation do you require for a metal building residential structure under 5,000 square feet?”
Determine drawing type needed based on their response, typically site-specific structural drawings for 99.5% of permitted locations
Obtain documentation before ordering your building, if required, or have plans ready for submission after ordering if allowed
PSF (pounds per square foot) requirements matter for engineering. This number represents the snow load your building must safely support. Your building department knows the required PSF for your area. Do not guess. A building engineered for 35 PSF will fail inspection in an area requiring 65 PSF.
Wind rating requirements work the same way. Coastal areas might require 170 mph ratings. Interior areas might only require 110 mph ratings. The engineer needs to know your exact requirements to design the building correctly.
Permit costs vary by location. Some areas charge a flat fee. Others charge based on building value. Budget $500 to $2,000 for permit fees, depending on your location and building size. This is completely separate from engineering costs.
The inspection process typically includes a footing inspection before the concrete pour, a foundation inspection after concrete cures, a framing inspection after shell installation, rough-in inspections for electrical and plumbing, an insulation inspection before drywall, and a final inspection before occupancy.
Schedule each inspection when the required work is complete. Do not cover up work that needs inspection. For example, do not pour concrete before the footing inspection. Do not install drywall before the rough-in inspection. Inspectors need to see the work, and uncovering it later costs time and money.
Q: Do I need a permit for a barndominium?
A: Most locations require building permits for habitable structures. Contact your local building department to determine specific requirements, which typically include site-specific engineered drawings for homes under 5,000 square feet.
Metal America’s Barndominium Shell Specifications
Metal America’s barndominium shell package includes everything you need for a weather-tight structure ready for interior finish. These specifications are non-negotiable for habitable structures because they meet engineering requirements and provide the durability you need.
The framing uses exclusively 12-gauge galvanized square tubing. This is the only gauge certified for habitable residential structures. The tubing measures 2-1/4 inches by 2-1/4 inches outside dimensions. Each piece is galvanized to prevent rust and comes with a 20-year rust-through warranty.
Panels are 26-gauge minimum thickness. This gauge provides adequate strength for residential structures while keeping weight manageable. The panels are corrugated steel with a galvanized coating and a baked-on enamel finish. You choose from available colors to match your preferences.
Leg configuration depends on building width. Buildings 30 feet wide and smaller use double legs. These two columns, side by side, provide extra strength and a wider mounting surface for interior finish work. Buildings over 30 feet wide use ladder legs, which are 1-foot-wide support structures that span the gap and support commercial trusses.
Spacing is 4 feet on center for all uprights. This closer spacing (compared to 5 feet typical on shops) provides the strength needed for living spaces that will have drywall, insulation, and other finish materials, adding weight. The 4-foot spacing also makes interior framing easier, since studs are standard dimensions.
Double-bubble insulation comes included on every barndominium. This material redirects 96% of radiant heat and acts as a vapor barrier when properly installed with sealing tape. You will add additional insulation during interior finish, but the double-bubble provides a good starting point.
Frame-outs for doors and windows are cut during fabrication. These openings include appropriately sized header bars. All frame-outs are slightly larger than your doors or windows to allow for shimming and adjustment during installation.
Metal America Barndominium Shell Package Includes
| Component | Specification | Why It Matters |
|---|---|---|
| Framing | 12-gauge square tubing only | 20-year rust warranty, certified for residential, stronger than 14-gauge |
| Panels | 26-gauge minimum | Adequate strength for habitable structures, better than standard 29-gauge |
| Legs | Double legs (≤30′ wide) or ladder legs (>30′) | Provides proper support and interior finish mounting surface |
| Spacing | 4 feet on center | Stronger than 5′ spacing, easier interior finish work |
| Base rails | Double or ladder depending on design | Creates stable foundation mounting surface |
| Insulation | Double-bubble included | Radiant barrier and vapor control, starting point for full insulation |
| Frame-outs | Cut to your specifications | Properly sized with header bars for doors and windows |
| Trim | Complete exterior trim package | Createsa stable foundation mounting surface |
Base rails are double or ladder design, matching your leg configuration. The rails bolt to your concrete foundation using expansion anchors. We install base rail sealant to create a watertight seal between the rails and concrete. This prevents water infiltration and keeps your structure dry.
All hardware is included. This means bolts, screws, anchors, and fasteners for complete assembly. Screws are self-drilling with neoprene washers to prevent leaks. The screws match your panel color for a finished appearance.
Professional installation comes with the package. Our crews deliver the building and assemble it on site. Installation typically takes 2 to 3 days, depending on building size and weather conditions. The crew ensures everything is square, plumb, and properly sealed before leaving.
Non-Negotiable Specs for Barndos
12-gauge frame required because this is the only gauge certified for habitable residential structures
26-gauge panel,s minimum, provide better durability thanthe standard 29-gauge used on carports
Double legs (≤30′ wide) or ladder legs (>30′) based on width, ensuring proper support for interior finishing
4-foot on-center spacing provides strength for residential loads and easier stud wall installation
Double-bubble insulation is included on every build as the starting point for a full insulation system
Frame-outs for doors/windows sized correctly with header bars during fabrication
Warranty coverage protects your investment. The 12-gauge frame carries a 20-year rust-through warranty. Panels carry a 20-year rust-through warranty plus color fade and chalk warranty, typically lasting 20 to 40 years, depending on the environment. Installation workmanship is warranted for 6 months from the completion date.
These specifications cost more than a standard carport or shop. The extra cost buys you a structure engineered and built to safely house humans. Trying to convert a cheaper shop into a home later creates problems with permits, insurance, and resale value. Build it right from the start.
Common Barndominium Mistakes to Avoid
People make expensive mistakes when building barndominiums. Learning from others’ errors saves you money and headaches. These mistakes keep occurring with customers who did not understand the process.
Not waiting for engineered drawings before pouring concrete tops the list. You need drawings first because they specify footer depths, anchor bolt locations, and other foundation requirements. Pour concrete first, and you might have to tear it out when the engineer requires different specifications.
Wrong concrete slab dimensions happen when people do not understand that building measurements are outside-to-outside. A 40-foot-wide building needs a 40-foot-wide slab, not a 39-foot-wide one. The base rails sit on the slab edges. Too-small slabs mean the base rails hang over the edge or rest on the ground. Metal America’s building measurements are outside-to-outside, so if you want exactly 30 feet of livable space, you must account for base rails and your own finishing materials to get the total width needed.
Forgetting the drip ledge on concrete leads to water infiltration. The notched edge lets panels extend past the slab so water cannot sneak under base rails. Pouring a slab flush with no ledge means adding Z-trim later or dealing with water problems forever.
Not accounting for base rail thickness in livable space calculations surprises people who wanted exactly 30 feet of interior width. The double base rails take up several inches. Add drywall and insulation and you lose more space. A 30-foot building gives you about 29 feet of finished interior width.
Not completing the underslab plumbing before the pour forces expensive solutions later. You cannot easily add plumbing under a cured slab. Some people try to core drill, which costs hundreds per hole and weakens the slab. Run all your water lines, drains, and electrical conduits before concrete gets poured. Remember that all Metal America buildings have double or ladder base rails, so any plumbing or electrical must be positioned far enough inboard to clear both base rail layers.
Not understanding egress requirements for bedrooms creates code violations. Every bedroom needs a proper escape window. The window sill cannot be more than 44 inches from the finished floor. The window must meet the minimum egress requirements. Planning bedrooms without considering these requirements means moving rooms or adding windows later.
Ordering the wrong building width happens when people do not account for interior finishing. A 32-foot-wide building requires ladder legs and commercial trusses, which cost significantly more than those for a 30-foot-wide building with double legs. Sometimes stepping down to 30 feet wide makes more sense economically, even though you lose 2 feet of interior space.
Not coordinating doors and windows before shell installation delays construction. Metal America can install your doors and windows during shell installation for $200 per unit. This requires having them on site before we arrive. If you order them late, you wait for them to arrive and pay someone else to install them after the shell is up.
Incorrect frame-out sizing creates problems with door and window installation. All openings need to be 1/2 inch larger than the door or window itself, or 3-1/2 inches larger if using wood blocking. Measure your doors and windows carefully before ordering the building. All frame-outs have header bars, which take up space.
Not verifying the lot is level before scheduling the shell installation leads to return trips. Our crews will not install on unlevel ground. If they arrive and your lot is not level within 3 inches front to back and side to side, they leave. You pay a return charge of $500 when the site is ready.
Critical Mistakes That Cost Money/Time
Not waiting for engineered drawings before pouring concrete can require tearing out the foundation and starting over
Wrong concrete slab dimensions from not understanding outside-to-outside measurements leave base rails unsupported
Forgetting the drip ledge on concrete leads to water infiltration problems under base rails
Not accounting for base rail thickness means less livable space than expected after interior finish
Not completing the underslab plumbing before pouring forces expensive core drilling or living without proper plumbing
Not understanding egress requirements for bedroom windows creates code violations requiring expensive fixes
Ordering the wrong building width by not accounting for interior finishing needs and truss requirements
Not coordinating doors/windows before shell installation delays the project and increases costs from $200 per unit to higher post-installation costs
Not verifying the lot is level results in a $500 return charge and construction delays
Double-check everything before signing contracts. Measure twice, order once. Ask questions if something is unclear. The Metal America team would rather answer 50 questions before you order than help you fix an expensive mistake after installation.
What to Expect When Working with Metal America
Working with Metal America follows a clear process from initial contact to final installation. Understanding each step helps you know when you need to make decisions and what happens next.
The initial consultation begins when you contact us via the website or by phone. We discuss your project goals, budget, and timeline. You tell us what size building you need, what features you want, and where the building will go. We ask questions about permits, financing, and site conditions.
We create an exact shell quote reflecting the highest price you approved. This quote includes the complete building specification, your chosen colors, all frame-outs for doors and windows, and delivery plus installation to your location. The quote clearly shows what Metal America provides versus what you handle separately.
If you need engineered drawings, we coordinate with our partners to provide them. You work directly with them to provide site information and building requirements. They create your site-specific drawings and charge you directly for that service.
If you need a concrete contractor, we can help with that, too. We maintain relationships with concrete contractors across our service area. These contractors understand metal building requirements and are familiar with drip ledges, base rail clearances, and proper slab dimensions. You hire them directly and work out payment terms with them.
If you want a general contractor to handle your entire interior build-out, we can recommend contractors in your area. The GC relationship is between you and them. We provide the shell, they provide everything else. This arrangement works well for customers who do not want to manage the construction process themselves. All contractors must meet strict requirements, including proper licensing, insurance coverage, and a two-million-dollar bond.
Shell manufacturing begins after you place your order and make your deposit. Lead times vary by manufacturer and current demand. Our ability to work with multiple manufacturers means we can find you either the best price or the fastest lead time, depending on your priority.
Delivery and installation happen when the building is ready, and your site is prepared. We schedule the installation for a specific week. The crew typically arrives 1-2 days into that week, depending on previous installations and weather. They deliver all materials, assemble the building, and clean up the site.
Payment is due upon shell completion. You walk through the building with the crew to verify everything looks correct. We can process credit cards (with 3.4% fee), ACH payments, or wire transfers. Cash or check works too. We do not accept payment until you confirm the shell is installed properly.
After the shell installation, the project is in your hands or your General Contractor’s hands. You hire contractors for interior finish work, or your GC coordinates everything. You schedule inspections with your building department. Metal America completed its part when the shell installation was finished. We operate as a dealer for the manufacturer, not as a builder, so all construction responsibilities beyond the shell are the GC’s responsibility.
The Metal America Process
Initial consultation and floor plan selection through phone or website contact
Exact shell quote with drawings specified and all features listed
Coordination with engineering partners if site-specific drawings are needed
Concrete contractor connection, if requested, from our network
General contractor connection, if requested, meeting strict licensing and insurance requirements
Shell manufacturing by the chosen manufacturer, lead time varies

Customer/GC takes over for interior buildout, Metal America’s work is complete
Communication primarily happens through email and phone. You get updates on manufacturing progress. We contact you when the building is ready to schedule installation. We reach out 1-2 weeks before installation to confirm your site is ready.
Site requirements must be met before installation. The lot must be level within 3 inches front-to-back and side-to-side. Concrete must be poured and cured. All underground utilities must be marked. You must have clear access for delivery trucks and the installation crew’s equipment.
Our crews need 10 feet of clearance around the entire building. This space lets them work safely and maneuver materials. Trees, fences, or other structures within that clearance zone cause problems. Sometimes we can work around obstacles, but it slows installation and might incur additional charges.

Frequently Asked Questions About Barndominiums
Q: Can I finance a barndominium?
A: Yes, you can finance barndominiums through traditional construction loans requiring 690+ credit, in-house financing options, or rent-to-own programs with no credit check required.
Q: Do barndominiums hold their value?
A: Well-built barndominiums typically hold value well and can increase property values by 5% to 10% compared to vacant land, especially in rural areas where they are common.
Q: Can I build a barndominium myself?
A: You can act as your own general contractor if paying cash, but construction loans require a licensed GC. Metal America provides the shell as a dealer, you handle interior or hire contractors.
Q: What is the lifespan of a barndominium?
A: The metal frame carries a 20-year rust-through warranty, but properly maintained barndominiums can last 50+ years or more with the steel structure remaining sound indefinitely.
Q: Are barndominiums energy efficient?
A: Barndominiums can be very energy efficient when properly insulated using closed-cell foam and adequate R-values, often performing better than poorly insulated stick-built homes.
Q: Can I add a second story later?
A: Adding a second story after initial construction is difficult and expensive because it requires additional interior structural support. Plan for two stories from the beginning if you want them.
Q: Do I need a general contractor?
A: You need a licensed general contractor if using a construction loan. Cash buyers can act as their own GC if they have the time and knowledge to coordinate trades.
Q: How customizable are barndominiums?
A: Barndominiums are extremely customizable since the metal shell is just an envelope. You can lay out the interior however you want, without load-bearing wall constraints.
Q: Can I live in a barndominium while building it?
A: Living in a barndominium during interior finish is possible, but requires some finished space with working utilities. Most people move in when at least the main living areas are complete.
Q: What maintenance does a barndominium require?
A: Metal barndominiums require minimal maintenance compared to wood structures. Touch up scratched paint when needed, check roof penetrations annually, and keep gutters clear.
