Do you need a building permit in Cheatham County, Tennessee?

Yes. In unincorporated Cheatham County, a permit is required before constructing, enlarging, altering, repairing, moving or demolishing a structure, changing occupancy, doing regulated electrical, gas, mechanical or plumbing work, or grading or filling land.1 The first accessory structure is exempt when it is no larger than 200 square feet.9

Permitted work receives footing, foundation, framing and rough-in, insulation, and final inspections.10 A building cannot be used or occupied until the building official issues a Certificate of Occupancy, and the final septic and driveway approvals must be complete before the county final inspection.11

Who issues building permits in Cheatham County?

Cheatham County Building & Codes administers building permits, inspections, zoning, subdivision rules and land use in the county’s unincorporated areas.12 The office is at 338 Frey Street in Ashland City and can be reached at (615) 792-7915 or [email protected].12

The county has adopted the 2018 International Residential Code, International Building Code and related codes as amended.13 County permit fees are published by project type; new homes, additions, manufactured homes and modular homes are charged at $0.60 per square foot, plus applicable county charges.14 Use the county’s online portal to apply, schedule an inspection or check permit status.12

Does Cheatham County have zoning?

Yes. Cheatham County enforces zoning and subdivision regulations in unincorporated Cheatham County; parcels inside a municipality need the applicable city’s answer instead.2 The county says there is no general minimum lot size to construct a home, but the zoning district must allow residential development.8

Do not read that as a promise that every parcel is buildable. Accessory structures must sit outside the required front setback and at least 5 feet from a side or rear setback.15 Mobile homes are limited to the Agriculture Zoning district, while manufactured and modular homes are allowed in residential zoning districts and require building permits.16 Building & Codes should confirm the parcel’s district, permitted use, setbacks and flood status before design work begins.3

How do septic permits work in Cheatham County?

TDEC, not the county building office, evaluates the site and determines the septic system required for Cheatham County property.4 A septic construction permit is required for a new system and for modification or repair of an existing system, and the permit must be presented before the county issues the building permit.5

Start before grading a pad or beginning construction.5 Only 16.2% of mapped county soils are rated without severe limitations for a conventional drain field, so a favorable site evaluation should not be assumed from acreage alone.17 After installation, the installer must arrange TDEC’s final inspection before covering the system; approval produces a Certificate of Completion.18 The TDEC Nashville Environmental Field Office serves Cheatham County at (615) 687-7000.19

Can you live in an RV or tiny home in Cheatham County?

Cheatham County’s reviewed materials do not give a complete answer for long-term RV living or temporary camping on an individual private parcel. Ask Building & Codes how the parcel’s zoning district, utilities and proposed length of stay affect the use before buying or moving an RV onsite.

A tiny home used as a dwelling is not exempt from the county’s construction standards merely because it is small. Exterior walls must be supported and attached to continuous solid or fully grouted masonry or concrete footings, the structure must meet the adopted residential code, and qualifying plans must be attested by a Tennessee-licensed engineer, architect or third-party inspection firm before a building permit is issued.7 The county has not confirmed a general minimum dwelling floor area, so ask Building & Codes about the specific zoning district and design.

Building a home in Cheatham County: what are the steps?

For unincorporated Cheatham County, use this order:

  1. Ask Building & Codes to verify zoning, flood-zone status and whether the property fronts a public road.3
  2. Obtain TDEC’s septic permit and site evaluation before dirt work.5
  3. Contact the Cheatham County Highway Department for a driveway permit even if a driveway already exists; state-route frontage also requires TDOT involvement.20
  4. Submit plans and the required contractor or owner-builder documentation, then pay the applicable county fees and taxes.3
  5. Schedule the county’s required construction inspections and obtain final septic and driveway approvals before the county final.1011

An owner may pull a permit for the owner’s own home once every 2 years if it will not be sold, leased or rented.6

What should you check before buying land in Cheatham County?

Confirm zoning, legal road frontage, driveway approval, flood status and septic suitability before treating a parcel as buildable.3 The terrain deserves an early site walk: only 44.6% of the county is at a slope of 15% or less, and 75.8% is wooded.2122 Those conditions can affect clearing, access and the practical placement of a house and drain field.

Ask the serving utility whether water or sewer is available; the county’s reviewed material does not establish a general connection rule or confirm a private-well permit requirement. A Tennessee utility with qualifying sewer infrastructure may require an existing building on an abutting parcel to connect, but that statewide authority does not prove sewer serves a particular property.23 A driveway on state highway right-of-way needs a TDOT permit.24

Watch-outs

  • A septic permit and driveway permit come before the county building-permit application, not after construction starts.3
  • Final septic and driveway approvals must be complete before the county’s final building inspection.11
