In short
- A complete barndominium budget has 12 line items, from land to contingency. Most overruns come from lines that never got a number.
- Planning ranges from the example builds on our cost guide: $30 to $60 per sq ft shell, $100 to $200 turnkey living, $20,000 to $80,000 for septic, water and power combined.
- Different people quote different lines. A kit supplier will not price your septic.
- Hold roughly 5 to 10 percent as contingency and spend it only on real surprises.

Building a barndominium near Tyler? This barndominium budget guide lists every line item to price, who gives you the number, and the miss that most often blows it up. Ranges come only from our own Tyler cost guide and cost calculator. They are planning ranges, not quotes.
The land and site lines: price these before you close
| Line item | Planning range | Who quotes it | Common miss |
|---|---|---|---|
| 1. Land and survey | None given | Seller, surveyor | Buying before checking utilities and soil |
| 2. Site prep (clearing, pad, fill) | $10,000 to $60,000 with driveway (low end of the smallest example to high end of the largest) | Dirt or site contractor | Heavily wooded lots and fill for clay soils |
| 3. Septic, well or water tap, power run | $20,000 to $80,000 combined (across our example builds) | Septic designer, well driller or water supply corporation, electric provider | A long power run to the back of the lot |
| 4. Driveway and culverts | In the site range above | Site contractor | Road-access rules and culverts at the road |
Lines 2 and 4 share the same $10,000 to $60,000 example range, so do not add it twice. Details on line 3 are in our septic and well guide.
Money trap: a price per square foot rarely includes site work. If a bid does not mention lines 2 to 4, assume they are extra and ask.
The building lines: shell, slab and everything inside
| Line item | Planning range | Who quotes it | Common miss |
|---|---|---|---|
| 5. Foundation / slab | None given | Builder or concrete contractor | Shell quote that leaves the slab out |
| 6. Shell or kit | $30 to $60 per sq ft (shell, sometimes with slab) | Kit supplier or builder | Doors, windows and wall height priced extra |
| 7. Erection | None given | Erection crew or builder | Assuming the kit price includes labor |
| 8. Dry-in (roof, walls, openings closed) | None given | Builder | Unclear whether dry-in means doors and windows are in |
| 9. Plumbing, electrical, HVAC | Inside turnkey range | Licensed trade contractors | Shop electrical load and large equipment |
| 10. Insulation | None given | Insulation contractor | Spray foam costs more than batt or blown-in |
| 11. Interior finish | $100 to $200 per sq ft turnkey living | Builder, with allowances | Low allowances for cabinets, flooring, fixtures |
For a shop house, ask for the shop priced on its own: our guide gives roughly $40 to $100 per sq ft for shop space. Our calculator splits the turnkey range into basic, mid and high finish tiers (about $100 to $150, $125 to $175 and $150 to $200); that split is ours, not a market standard.
The paperwork lines: permits, fees and money costs
| Line item | Planning range | Who quotes it | Common miss |
|---|---|---|---|
| 12. Permits, survey, insurance, loan costs | Several percent of the build | County or city, insurer, lender | Interest during construction |
Permit rules differ inside Tyler and in unincorporated Smith County; see the permits guide. Loan costs and draws are covered in our financing overview.
How to use a contingency without wasting it
- Set it as its own line
Roughly 5 to 10 percent of the build, kept separate from every other line.
- Go higher when the unknowns are big
Unknown soil, heavy clearing or a long utility run argue for the upper end.
- Spend it only on surprises
Not on upgrades. A nicer countertop is a selection change, not a contingency item.
- Log every draw
Write the date, amount and reason each time, so you know what is left before the next decision.
Saves money: ask every bidder to price the same plan against these 12 lines, then compare line by line. The gaps show you which bid left something out.
Next: check the budget against real quotes
- Run your size through the cost calculator for a low-to-high planning range.
- Print the free build checklist for the order of tasks and 40 questions; this page is about the money lines, not the task order.
- Read how to choose a builder before collecting bids.

Frequently asked questions
What line items belong in a barndominium budget?
Land, site prep, foundation/slab, the shell or kit, erection, dry-in, plumbing/electrical/HVAC, insulation, interior finish, septic and well or water tap, driveway, permits and fees, and a contingency. The table on this page lists each with who quotes it.
Is the slab included in a barndominium shell price?
Not always. Some quotes cover only the structure, some include the slab, some include everything to move-in. Ask each bidder exactly where the quote starts and stops.
How much contingency should I hold?
Our cost guide suggests roughly 5 to 10 percent of the build in reserve. Rural lots with unknown soil or a long utility run argue for the higher end.
Do the ranges here replace a quote?
No. They are the planning ranges already published in our Tyler cost guide and calculator. Where a line has no range, we give none; get written quotes.
