Building permits, zoning and land rules in Putnam County, Tennessee

Yes. Putnam County Codes requires permits in the unincorporated county for all new residential and commercial buildings, additions, decks or porches, modular homes, garages or storage buildings over 200 square feet, and plumbing or mechanical additions¹. Putnam County has adopted the 2018 International Building Code and 2018 International Residential Code for the construction it regulates¹. The department schedules inspections and issues occupancy certificates, and a final inspection is required before a building is inhabited⁶. Putnam County also requires plumbers and HVAC contractors to hold a county license renewed annually for $50⁶. Tennessee's owner-builder rule allows a property owner one permit every two years for a single home intended for the owner's own use, not for sale, lease, or rent; a paid contractor treated as the prime must be licensed and obtain the permit⁵.

Putnam County Codes handles building, plumbing and mechanical permits, inspections, permit records, and occupancy certificates for construction in the unincorporated county⁶. The office is at 270 Carlen Ave, Cookeville, Tennessee, and its phone number is 931-526-2285⁶. Its published hours are Monday through Friday from 7:00 a.m. to 3:30 p.m⁶.. The county publishes a building, plumbing and mechanical permit-fee schedule, but the available record does not establish a complete current valuation table; ask Codes for the charge on a specific project¹. For subdivision plats and mapped floodplains, contact the Putnam County Regional Planning Commission at 67 S. Elm Ave., Cookeville, or 931-372-0070². Ask the Highway Department about county-road access because the confirmed driveway-cut provision is limited to houses built immediately by a subdivision developer^7,8.

Unincorporated Putnam County has no countywide zoning code or zoning districts^2,6. County zoning therefore sets no minimum dwelling size, lot coverage, or building-height limit². Subdivision rules are the important exception: covered lots with public water and sewer must contain at least 7,500 square feet, while covered lots with public water but no public sewer must contain at least 20,000 square feet; both require 75 feet of width at the building setback line⁸. Covered subdivision lots also have road-based building lines and a 10-foot minimum setback from other lot lines⁸. Putnam County separately enforces floodplain zoning in FEMA-identified 100-year flood plains². Algood, Baxter, Cookeville, and Monterey apply their own development codes inside city limits².

TDEC, not Putnam County, administers septic permits and inspections for property in Putnam County³. A state septic construction permit is required for a new, modified, repaired, conventional, or alternative system, and it should be obtained before dirt work or construction of a building pad begins^3,4. Alternative systems require an extra-high-intensity soils map prepared by a Tennessee-licensed soils consultant⁴. TDEC performs the final inspection before the installation is covered and issues a Certificate of Completion after approval⁴. Call TDEC at 1-888-891-8332 to identify the appropriate Environmental Field Office⁹. Only 22% of surveyed Putnam County soil is rated without severe limits for a conventional drain field, so make septic suitability an early purchase contingency¹⁰. Putnam County's building-permit sequence places the state septic permit before the county building permit^1,6.

Unincorporated Putnam County imposes no county zoning restriction on RV occupancy, temporary camping, tiny-home occupancy, manufactured-home occupancy, or accessory dwellings². That zoning answer is not blanket permission to occupy any structure: construction permits, building and installation standards, septic or sewer requirements, subdivision rules, floodplain rules, and applicable state requirements still apply². Putnam County specifically requires a building permit for a modular home and other listed construction¹. Property inside Algood, Baxter, Cookeville, or Monterey follows the applicable city's development codes². Before moving onto a parcel, show Putnam County Codes the exact structure and utility plan, confirm sanitation requirements with TDEC, and review the deed and plat for private restrictions.

1. Confirm that the parcel is outside Algood, Baxter, Cookeville, and Monterey; city development codes apply inside those municipalities².
2. For new construction, request a 911 address after the required stakes are present¹.
3. Obtain the TDEC septic permit before the county building permit^1,6.
4. Purchase the building, plumbing, and mechanical permits from Putnam County Codes, then post the address and building permit¹.
5. Before inspections, provide the portable toilet, crushed-stone ramp, erosion controls, posted address, and posted permit required by the county¹.
6. Schedule the footer, foundation, slab-plumbing when needed, concrete-slab, combined rough-in, energy, and final inspections in order¹.
7. Do not inhabit the building before the final inspection; Putnam County Codes issues occupancy certificates⁶.
8. Obtain a TDOT permit before constructing or changing a driveway on state highway right-of-way¹¹.

Check septic feasibility first: only 22% of surveyed Putnam County soil is rated without severe limits for a conventional drain field¹⁰. Ask the Regional Planning Commission whether the parcel lies in a FEMA-identified 100-year floodplain and whether a proposed division triggers subdivision review². For subdivision plats, proposed public sewer and water connections must be shown where available; when connections are impracticable, the proposed individual water or sewage system needs the specified TDEC and planning-engineer approvals¹². Verify whether access is from a state highway or county road because TDOT requires a permit on state highway right-of-way, while the county source does not establish a driveway permit for every county-road parcel^8,11. Putnam County's effective property-tax rate is about 0.5%, and its median annual property-tax bill is about $1,299¹⁰. The reviewed sources do not confirm a private domestic well-permit rule; ask TDEC before treating a well as the water plan.
