Barndominium Builders Tennessee: What to Know Before You Build
If you’re comparing barndominium builders Tennessee has to offer, start with the land, the intended use and the full project budget, not just the price of a steel shell. A barndominium can be built in Tennessee, but it still needs to meet local zoning, permitting and residential construction requirements when it will be used as a home. Cost depends on what you finish, the site conditions and how much work you manage yourself.
What is a barndominium, and what isn’t?
“Barndominium” can describe a few different buildings. A metal shop with a small living area is not automatically the same as a fully finished home. A true residential barndominium is designed and built for people to live in, with appropriate structure, insulation, electrical and plumbing systems, heating and cooling, and code-compliant living space.
A pole-barn conversion starts with a building originally designed for another purpose. Converting one to a residence may require significant structural, moisture-control, insulation and code work. It’s worth getting the existing building assessed before assuming conversion will cost less than new construction.
Also ask your insurance agent and lender about the specific design before committing. Some insurers and lenders may be less familiar with barndominiums, and appraisal can be challenging when there are few comparable homes nearby. Confirm their requirements early. A barndominium still needs to meet applicable residential standards and satisfy the lender’s and appraiser’s requirements to qualify as a home.
Barndominium construction: kit or turnkey builder?
Searching for barndominium kits Tennessee suppliers offer can be a useful starting point. A kit or shell can provide the building components, but it doesn’t necessarily cover the slab, site work, permits, utilities, interior finishes or trade coordination. Ask exactly what is included, and what is not.
| Route | What to expect | Often suits |
|---|---|---|
| Kit or shell | You arrange delivery, foundation, crews, inspections, utilities and interior work. | Owners with construction experience, time and reliable local trades. |
| Turnkey construction | A builder coordinates multiple phases and trades under an agreed scope. | Owners who want one point of accountability and less day-to-day coordination. |
A kit may reduce material costs, but you’ll need to sequence work and keep the project moving. If one trade is late or work is out of order, other crews can be delayed or asked to return. A turnkey project generally costs more than a shell-only route, but project management is part of the value.
Backyard Boys Construction is an authorized Capital Steel dealer and provides steel building erection and full barndominium construction. The company does not claim to manufacture kits or offer shell-only packages. Its barndominium construction service is a route for owners looking for a coordinated build.
Is a barndominium allowed in Tennessee?
Often, yes, but whether a particular lot can support one depends on its zoning, access, setbacks, utilities and local rules. Requirements can differ between county and city jurisdictions. Davidson, Williamson, Rutherford, Maury, Dickson, Cheatham and Hickman counties each have their own permitting and inspection processes; towns within a county may also have separate requirements.
Rural acreage in Maury, Dickson, Cheatham and Hickman counties may offer more room for a home-and-shop layout. That doesn’t guarantee approval. Tighter suburban lots around Franklin, Brentwood or Nashville can limit building placement, driveway access, setbacks or the size of a shop. Check with the authority that has jurisdiction over the parcel before settling on a floor plan.
Tennessee also has varied soil and site conditions. Clay, drainage, slope, fill and rock can affect excavation and foundation design. There isn’t one frost-depth assumption that should be used for every site. Your plans and foundation should be suited to the location and reviewed under the applicable code. Ask the local building official and design professional what applies to your property. State residential permit information is available through the Tennessee Department of Commerce and Insurance.
What does a barndominium cost in Tennessee?
There isn’t one reliable price per square foot for every barndominium. For early planning, the following are broad estimates, not quotes. They vary with design, location, material choices and the amount of owner-managed work.
- Shell only: Roughly $40–$80 per square foot of building footprint as a planning range. Clarify whether the estimate includes erection, roof and wall panels, doors, windows and delivery. Foundation, utilities and interior work are commonly separate.
- Shell plus interior finish-out: Roughly $120–$200 per square foot of finished living area as an early budgeting range. This may include insulation, HVAC, electrical, plumbing, drywall and standard interior finishes, depending on the scope.
- Full turnkey build: Roughly $160–$250 or more per square foot of finished living area as a broad planning range. A larger shop or garage adds cost even if it isn’t finished living space. Confirm whether the estimate includes site preparation, foundation, utilities, permits and final finishes.
Those ranges are not directly interchangeable: a shell is often priced against the whole footprint, while interior and turnkey figures may be discussed per finished living area. Land, financing, unusual site work and some utility costs may be outside a preliminary estimate.
Key cost drivers include:
- Living space versus shop: Kitchens, bathrooms and finished rooms cost more than open storage or workshop space.
- Site and foundation: Clearing, grading, drainage, access, soil conditions and slab design can shift the budget.
- Insulation and windows: These affect comfort and energy use through Tennessee’s hot, humid summers and cold spells.
- Utilities: Rural properties may need a well, septic system, longer utility runs or a new driveway.
- Finish choices: Cabinetry, flooring, fixtures, doors and windows all affect the finish-out.
For a useful comparison, ask contractors to identify assumptions, exclusions and allowances in writing. Don’t compare a shell price with a finished-home price.
What to expect during the build
A typical project moves through these stages, though the order and approvals can vary by site:
- Land and site evaluation. Review access, slope, drainage, setbacks, utilities and the intended placement of the home and shop. Confirm zoning and ask whether a septic evaluation or other site review is needed.
- Design and engineering. Finalize the floor plan and building specifications. Structural plans should be prepared and stamped where required for the Tennessee jurisdiction and project.
- Permitting. Submit plans and confirm the required permits and inspections with the county or city authority. Check utility and septic requirements separately where applicable.
- Slab and foundation. Prepare the site, establish drainage and build the foundation to the approved plans. Changes after the steel package is ordered can be costly.
- Steel erection. Erect the structure and install the exterior envelope according to the design and manufacturer’s specifications.
- Rough-in and finish. Coordinate plumbing, electrical, HVAC and insulation before closing up interior walls. Then install interior finishes and fixtures.
- Final inspections and walkthrough. Complete required inspections, address outstanding items and review the finished work.
The sequence matters. If site preparation, foundation dimensions or trade schedules aren’t coordinated, crews may have to wait, redo work or return after another phase. A turnkey contractor can manage that coordination under one roof. Backyard Boys Construction has more than 37 years of construction experience, dating to 1987, and serves Middle Tennessee homeowners from Franklin and Brentwood through the seven counties listed above.
Mistakes to avoid
- Underestimating site work. A clear-looking lot can still need drainage improvements, grading, a longer driveway or utility work.
- Making the shop too small. Decide what equipment, vehicles or work areas you’ll need before fixing the building footprint.
- Cutting back on insulation. Tennessee heat and humidity make the wall, roof and air-sealing plan important to comfort.
- Waiting to ask about appraisal. Discuss the building type and plans with your lender and appraiser before construction starts. Don’t assume a completed build will appraise to the amount you spent.
- Skipping contingency. Keep room in the budget for unknown site conditions, approved design changes and material or labor adjustments.
FAQ
Can I build a barndominium on my Tennessee property?
Possibly. Confirm zoning, setbacks, access, utilities and permit requirements with the county or city that governs the parcel before buying plans or ordering materials.
Can I get a mortgage on a barndominium in Tennessee?
Some buyers finance barndominiums, but lender rules and appraisal requirements vary. Ask your lender early whether it will finance the specific structure and what plans, builder documents and inspections it requires. This is general information, not lending advice.
Do I need a kit to build a barndominium?
No. A kit or shell is one route; hiring a builder to manage a broader scope is another. Compare what each option includes, who arranges the trades, and who is responsible for inspections and coordination.
How long does construction take?
As a rough planning estimate, a full build may take about 8–14 months from finalized plans and a ready site to completion. Design, permitting, weather, site conditions and material or trade schedules can extend the timeline.
Are steel buildings the same as barndominiums?
No. A steel building is a structure type. A barndominium is a home designed to include residential living space, sometimes alongside a shop or garage. A steel building used as a home must still meet the applicable residential requirements.
Should I finish the shop at the same time as the home?
Not necessarily. If the shop can remain unfinished without affecting the home’s design, structure or approvals, finishing it later may suit your budget. Plan its size, access and utilities early, and confirm any future work with the relevant local authority.
