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

Yes. Coffee County requires a local building permit for covered construction, and Coffee County Codes regulates construction and code compliance countywide¹. Tennessee's residential rules cover new homes and additions over 30 square feet, while detached non-living structures and manufactured-home installation have stated exceptions under the state program⁶. Coffee County publishes its own building-fee schedule, including separate finished-space and unfinished-space charges, so get the local calculation before work begins⁷. The applicable statewide residential standards include the 2018 International Residential Code and 2018 International Energy Conservation Code, both with amendments⁸.

Coffee County Codes Compliance is the local building office. It is at 1329 McArthur Street, Suite 2, Manchester, TN 37355; call 931-723-4841 or email codes@coffeecountytn.org¹. The office regulates construction, materials, use and occupancy, and the location and maintenance of buildings and related equipment¹. Published hours are Monday through Friday from 8 a.m. to 4:30 p.m., with a closure from 11:30 a.m. to 12:30 p.m¹.. Ask which application, plans and trade permits your project needs because the available county materials do not establish the complete building-permit checklist⁹. Residential work generally receives foundation, rough-in or framing, and final inspections; certain slab foundations may add another inspection¹⁰.

Yes. Coffee County administers zoning outside incorporated municipalities, while cities may apply their own rules^1,11. For districts other than A-1, the published table uses minimum development areas of 0.80 acre with public water and minimum fire flow, 1 acre with public water, or 2 acres; A-1 has a 5-acre minimum lot size². The listed non-A-1 categories have 50-foot front and 25-foot rear and side setbacks, while A-1 buildings have 50-foot setbacks from every property line². The same non-A-1 table shows maximum building coverage as N/A, but that does not answer every district or A-1². Agricultural buildings have a setback exemption in the county schedule, not a blanket exemption from other rules². Subdividing is a separate approval: the Coffee County Planning Commission reviews minor and major subdivisions, with a published $150 fee for a preliminary or final plat⁹.

TDEC's Division of Water Resources, rather than Coffee County, administers septic permitting because Coffee County is not among Tennessee's listed contract counties³. Obtain the permit before installing, modifying or repairing a system and before grading a building pad⁴. TDEC may require site plans or soils maps, and an alternative-system application requires an extra-high-intensity soils map from a Tennessee-licensed soils consultant⁴. Processing may take up to 45 days after a complete application, and the process includes a TDEC site evaluation⁴. Septic permits stay with TDEC for every address in Coffee County, even where the county Codes office issues the building permit³. The installer contacts the local TDEC Environmental Scientist to schedule the final inspection, which must occur before the system is covered and ends in a Certificate of Completion¹². Only about 27.7% of Coffee County soils are rated without severe limitations for a conventional drain field, so verify the site before fixing a house location¹³.

We could not confirm a Coffee County rule that specifically authorizes or prohibits long-term RV occupancy, temporary camping or tiny-home occupancy on private land. Coffee County has zoning in unincorporated areas, and the Codes Department regulates use and occupancy of property, so the answer may depend on the parcel's district and proposed setup¹. Before buying land or moving a unit onto it, give Planning and Zoning the parcel number, zoning district, intended length of stay, utility plan and whether the unit will be the principal residence. Coffee County's published planning fees include a $200 temporary use permit, but the page does not say whether it covers RV stays, so ask whether it applies⁹. Ask separately about setbacks, septic approval and any temporary-use or special-exception process. For accessory dwellings and minimum dwelling size, Coffee County Planning and Zoning should also confirm the rule for the specific parcel¹.

1. Ask Coffee County Planning and Zoning to confirm the parcel's district, minimum lot size, setbacks and proposed use².
2. If the parcel will use septic, obtain TDEC approval before grading a building pad or beginning construction⁴.
3. Submit the required project information and obtain the building permit from Coffee County Codes^1,9.
4. An owner-builder must keep the home for personal use and may use the exemption only once every two years; paid work of $25,000 or more still requires a licensed contractor¹⁰.
5. Obtain a TDOT entrance permit for work on state highway right-of-way¹⁴.
6. Arrange the required building inspections and have the TDEC Environmental Scientist inspect the septic system before it is covered^10,12.

Confirm the zoning district, minimum lot size and setbacks with Coffee County Planning and Zoning before choosing a building site². Verify septic feasibility early because only about 27.7% of county soils lack severe conventional-drain-field limitations¹³. Ask the Highway Department about county-road access, while work on state highway right-of-way requires a TDOT entrance permit^14,15. A qualifying sewer utility may require connection when a building's lot abuts a public way containing its sanitary sewer¹⁶. For electrical service, written notice must show public sewer service, a septic application or an existing septic system³. Local floodplain review may be required before grading, fill or construction, but Coffee County's administering office remains unconfirmed¹⁷.
