Barndominium Builders in Putnam County, TN

Putnam County is the Upper Cumberland's regional centre, sitting on the western edge of the Cumberland Plateau where it breaks down onto the Highland Rim. Two things make it unusual for this kind of build: the county enforces the 2018 IRC through its own codes department, and it has no county-wide zoning whatsoever, so outside the four municipalities there is no district to qualify for, no minimum floor area and no siding restriction. Cookeville, Algood, Baxter and Monterey each set their own rules inside their limits, and Cookeville is one of the few Tennessee cities that publishes a filled-in Table R301.2.

Building code enforcement
Putnam County enforces its own codes. The Putnam County Codes and Planning Department has adopted the 2018 IBC and the 2018 IRC and enforces both in the unincorporated county, issuing permits, scheduling inspections and issuing occupancy certificates from 270 Carlen Ave in Cookeville. The State Fire Marshal's Office list of places where a state residential permit is required names seven counties, and Putnam is not among them.

There is no county zoning
Putnam County states plainly that it has no county-wide zoning regulations and no formal zoning code. In the unincorporated county that means no district to qualify for, no minimum lot size, no minimum heated floor area, no roof-pitch rule and no restriction on exterior cladding material. The county even notes that a Planned Unit Development is impossible here, because a PUD is a construct of zoning and there is none — a division of land is reviewed as a subdivision instead.

Cookeville publishes a filled-in Table R301.2
Most Tennessee jurisdictions leave the design criteria table blank. Cookeville fills it in: ultimate design wind speed 115 mph, seismic design category C, ground snow load 10 psf, frost line depth 12 inches, winter design temperature 20 degrees, mean annual temperature 53.7, air freezing index 1500 or less, termite protection required, decay and weathering moderate to heavy, with exterior wall insulation R-13, attic R-38 and windows at U-0.35 and SHGC 0.25. Those figures govern inside the city limits only.

Design criteria outside the cities
Putnam County publishes no design criteria table of its own. On a rural parcel the ultimate design wind speed, seismic design category, ground snow load and frost depth are confirmed in writing with the county building official before the frame is ordered, rather than read off a county sheet. Tennessee leaves every cell of Table R301.2 for the local jurisdiction to fill in, and the county has not filled it.

Climate zone 4A
Putnam County is IECC climate zone 4A, along with every other Cumberland Plateau county. Tennessee's zone 3A counties are all in West Tennessee. A kit or plan set specified for 3A is specified for a warmer place than this, and Cookeville's own published R-38 attic and U-0.35 window figures are the zone 4 numbers. In a steel or post-frame wall the difference shows up as continuous exterior insulation rather than deeper cavities, because the framing depth is fixed by the frame.

Karst, and why conditions vary inside one county
Putnam straddles the western escarpment of the Cumberland Plateau where it breaks down onto the Eastern Highland Rim. About half the county, the half holding Cookeville, Algood and Baxter, sits on the Rim at roughly 900 to 1,150 feet over Mississippian carbonate rock; Monterey is up on the Plateau proper. Sinkhole plains are characteristic of the base of the escarpment, so shallow limestone and closed depressions on one side of the county and deeper residual soils elsewhere are both normal. Cookeville takes this seriously enough to zone for it, mapping a Sinkhole Retention Area district from a sinkhole floodplain report prepared by Tennessee Tech and adopted by the city, with land inside it shown on approved plats as unbuildable.

Metal siding in Cookeville — check which section applies
Cookeville's Section 208A architectural design requirements set a list of acceptable exterior materials and put metal siding and metal panels behind Architectural Design Review Board approval. That clause does not reach a house. Section 208A.2A exempts individual single family and duplex developments from the whole of Section 208A. It applies to commercial, multi-family and industrial work, so it matters for a shop or a commercial post-frame building in the city, not for a single-family barndominium.

The seven inspections
Putnam County inspects in a fixed order for all structures: footer before concrete is ordered; foundations, anchor bolts, sill plate and basement drains; plumbing in slabs where required; concrete slabs; a combined rough-in for framing, plumbing and mechanical; energy, covering insulation values or trade-offs; and final before the building is occupied. Before any inspection the site needs a portable toilet, a crushed stone ramp to keep mud off the road, silt fence or straw bales, the 911 address posted and the permit posted.

Septic runs through the state, not the county
Putnam is not one of the counties that runs its own septic programme. The county's published permit steps send applicants to the state environmental office, and subsurface sewage disposal permits are handled by TDEC's Division of Water Resources through the Cookeville Environmental Field Office on (931) 520-6688. The soil and site evaluation comes before the permit, and on the Plateau edge the slope and depth-to-rock thresholds are the ones that decide a lot.

What a division of land triggers
Even with no zoning, Putnam County has adopted subdivision regulations, and dividing a tract puts the plat in front of the Regional Planning Commission. It meets at 5:30 p.m. on the second Tuesday of each month at the Cookeville Community Center on Carlen Drive, with a submittal deadline of 4:00 p.m. on the 22nd of the preceding month and five full-size copies of the plat brought to the meeting alongside a PDF filed with the planning department. Buying a parcel that already exists on its own deed avoids the process entirely.

Four cities, and the rest is county
Putnam County holds 401 square miles and four municipalities — the cities of Cookeville and Algood and the towns of Baxter and Monterey. The county states that it and the planning commission have no jurisdiction inside any of them, and that property inside those limits complies with that city's zoning, building codes and subdivision regulations instead. So the first question on any parcel here is which side of a city line it sits on, and for most rural acreage the answer is the county.

Cookeville lot rules if you build inside the city
Cookeville has no agricultural or rural district. A detached single-family dwelling is permitted in RS-20, minimum lot 20,000 square feet, and in RS-15, minimum lot 15,000 square feet with public wastewater. Front yard 30 feet, rear 25, interior side 10, and maximum lot coverage of 40 percent including accessory buildings — which on a 15,000 square foot lot caps the whole footprint, shop included, at 6,000 square feet. Neither district sets a minimum dwelling floor area, and Section 204.2 leaves building height unrestricted except as the building code regulates it.

Cookeville reviews its own commercial plans
The State Fire Marshal's Office lists the jurisdictions authorised to perform independent plans review and inspections for buildings that would otherwise need state approval. Cookeville is on that list and is the only municipality in the Upper Cumberland on it — the rest are the large metros and a handful of Middle and East Tennessee suburbs and counties. Putnam County is not on it, so a commercial building on unincorporated land follows a different plans route from one inside the city.

Contractor licensing and the $25,000 line
Tennessee requires a contractor's licence for projects of $25,000 or more, counted on the complete project cost including labour and materials, and separate phases or contracts cannot be used to stay under it. A property owner may build on their own land for their own use. Putnam County adds one of its own on top: a Special Plumbers License costing $50.00 a year, required by the county from all plumbers and HVAC contractors working here.

Below the slab

The expensive surprises are in the ground, not the building

What moves a Tennessee budget is usually below grade: limestone sitting shallow, karst voids and sinkholes, and slope. Those are the same conditions that decide whether a septic field passes its soil and site evaluation, so the grading plan, the footing depth and the drainfield get resolved together rather than one at a time. We price the dirt before we price the building.

Building in Putnam County: common questions

7 questions we get asked most often about building in Putnam County. If yours is not on the list, ask it directly.

Start your project
Do I need a building permit in Putnam County?
Yes. Putnam County enforces its own codes and has adopted the 2018 IBC and the 2018 IRC, which it enforces throughout the unincorporated county. The Codes and Planning Department at 270 Carlen Ave in Cookeville takes the application, collects the fee, issues the permit, schedules the inspections and issues the certificate of occupancy. Permits are required for all new buildings residential and commercial, for additions, for decks and porches added to an existing building, for modular homes and for any garage or storage building over 200 square feet. This matters because Tennessee is not uniform: a county or municipality can vote itself out of the residential code by a two-thirds resolution under T.C.A. 68-120-101, and several counties nearby have. Putnam has not. If your parcel is inside Cookeville, Algood, Baxter or Monterey, the city permits the work instead, and Putnam County and its planning commission have no jurisdiction there.
Is there zoning on rural land in Putnam County?
No. The county states it has no county-wide zoning regulations and no formal zoning code. On unincorporated acreage there is no zoning district to qualify for, no minimum lot size, no minimum heated floor area, no minimum roof pitch, no required porch or garage and no restriction on what the exterior is clad in. That is unusual and it removes the single biggest obstacle this kind of building normally runs into. Two things still apply. The county enforces floodplain regulations inside the FEMA 100-year floodplain. And if the land is being divided, the Putnam County Subdivision Regulations apply and the plat goes before the Regional Planning Commission. Buying a parcel that already stands on its own deed avoids the second of those. Inside the four municipalities the picture is completely different — each has its own zoning ordinance and its own building department.
What design wind speed and seismic category should the frame be engineered to?
It depends which side of the Cookeville city line you are on. Cookeville publishes a filled-in design criteria table: 115 mph ultimate design wind speed, seismic design category C, ground snow load 10 psf and a 12-inch frost line. Putnam County publishes nothing equivalent for the unincorporated area, which is normal — Tennessee leaves every cell of Table R301.2 for the local jurisdiction to fill in and most never do. On a rural parcel those numbers get confirmed in writing with the county building official before the frame is ordered rather than interpolated off a national map. On the seismic question specifically, Tennessee replaced the 2018 IRC seismic figure by amendment and uses the 2015 IRC Figure R301.2(2) Site Class D map, so a category read off a current national figure is read off a map Tennessee does not use. At Cookeville's published category C, a detached one- or two-family dwelling sits below the R301.2.2 threshold at which the IRC seismic provisions become mandatory; a townhouse does not.
Can a barndominium in Putnam County have metal siding?
On unincorporated land, yes, without qualification — the county has no zoning and therefore no exterior material standard at all. Inside Cookeville the answer needs care. Section 208A of the Cookeville zoning code sets a list of acceptable exterior materials and puts metal siding and metal panels behind approval by the Architectural Design Review Board. Read on its own that looks like a ban, and it is not one for a house: Section 208A.2A exempts individual single family and duplex developments from the whole of Section 208A. The materials list reaches commercial, multi-family and industrial buildings. So a single-family barndominium inside Cookeville is not caught by it, while a detached commercial shop on the same site could be. If the exterior finish matters to you, we confirm which section applies to your specific parcel and use before anything is ordered.
How does the ground affect what the foundation costs here?
More than in most Tennessee counties, because Putnam sits on the seam. About half the county, including Cookeville, Algood and Baxter, is Eastern Highland Rim underlain by Mississippian carbonate rock at roughly 900 to 1,150 feet; the eastern end around Monterey is up on the Cumberland Plateau proper. Sinkhole plains are characteristic of the base of the plateau escarpment, which is why Cookeville is one of very few Tennessee cities with a Sinkhole Retention Area zoning district, mapped from a sinkhole floodplain report prepared by Tennessee Tech and adopted by the city, with land inside it labelled unbuildable on approved plats. In practice that means shallow rock and closed depressions on some parcels and deeper residual soil on others, sometimes within a few miles. What we will not do is quote an excavation before the ground is tested. A clear-span steel or post-frame building concentrates its load into a small number of column bases, so what is under those bases is worth knowing early.
Who issues the septic permit, and when should it happen?
The state, not the county. Putnam is not one of the Tennessee counties that runs its own septic programme under contract, and the county's own list of permit steps sends you to the state environmental office before you buy the building permit. Subsurface sewage disposal systems are permitted by TDEC's Division of Water Resources under Rules 0400-48-01, through the Cookeville Environmental Field Office on (931) 520-6688. A soil and site evaluation comes first, and it is the step to do before committing to a parcel rather than after. Depth to rock, slope and percolation rate are what decide whether a conventional field will work, and on the plateau edge those are exactly the things that vary. The order the county publishes is worth following literally: 911 address first, then the septic permit from the state, then the building, plumbing and mechanical permits from the county.
Do I need a licensed contractor to build here?
Tennessee requires a contractor's licence for a project of $25,000 or more, and the threshold is counted on the complete cost of the project including both labour and materials. Splitting the work into separate phases, purchase orders or contracts to stay under it is not permitted. A property owner may build on their own property for their own use, though that exemption does not extend to commercial construction. Putnam County adds a requirement of its own on top of the state one: a Special Plumbers License, $50.00 renewed yearly, which the county requires from all plumbers and HVAC contractors working in its jurisdiction. Worth asking about when you are comparing quotes, because it is a local requirement that a contractor coming in from another county may not have.

What clients say

4.9 out of 5 based on 8 reviews Placeholder content

We had ten acres outside town and no idea what we could legally put on it. They pulled the zoning and the A-1 lot minimum before we spent anything on drawings, which saved us from buying plans for a building that would not have been approved.

Dale W. July 18, 2026

Ordered the shell kit and erected it with my brother-in-law over about six weekends. The drawings were clear, the bolt schedule matched what showed up on the truck, and the county inspector had no issues with the engineering.

Marisol T. June 2, 2026

Turnkey from a cleared lot to certificate of occupancy. What I appreciated most was that when plan review came back with comments, I heard about it the same day along with what they were doing about it.
