In unincorporated Coffee County, Tennessee, building permits come from Coffee County Codes, which regulates construction countywide12. County zoning applies outside incorporated municipalities, with A-1 land requiring 5 acres per lot34. Septic permits come from the state: TDEC, not the county, issues them and requires one before installation, modification or repair56.

Do you need a building permit in Coffee County, Tennessee?
Yes. Coffee County requires a local building permit for covered construction, and Coffee County Codes regulates construction and code compliance countywide12. 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 program11. Coffee County publishes its own building-fee schedule, including separate finished-space and unfinished-space charges, so get the local calculation before work begins12. The applicable statewide residential standards include the 2018 International Residential Code and 2018 International Energy Conservation Code, both with amendments13.
Who issues Coffee County building permits, and how do you reach them?
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.org2. The office regulates construction, materials, use and occupancy, and the location and maintenance of buildings and related equipment2. 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.m.2. Ask which application, plans and trade permits your project needs because the available county materials do not establish the complete building-permit checklist14. Residential work generally receives foundation, rough-in or framing, and final inspections; certain slab foundations may add another inspection15.
Does Coffee County have zoning, setbacks and land-use rules?
Yes. Coffee County administers zoning outside incorporated municipalities, while cities may apply their own rules1617. 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 size4. 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 line8. The same non-A-1 table shows maximum building coverage as N/A, but that does not answer every district or A-118. Agricultural buildings have a setback exemption in the county schedule, not a blanket exemption from other rules19. 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 plat20.
How do septic permits work in Coffee County?
TDEC's Division of Water Resources, rather than Coffee County, administers septic permitting because Coffee County is not among Tennessee's listed contract counties5. Obtain the permit before installing, modifying or repairing a system and before grading a building pad216. 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 consultant21. Processing may take up to 45 days after a complete application, and the process includes a TDEC site evaluation22. Septic permits stay with TDEC for every address in Coffee County, even where the county Codes office issues the building permit5. 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 Completion23. 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 location24.
Can you live in an RV or tiny home on land in Coffee County?
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 setup72. 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 applies25. 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 parcel9.
How do you build a home in Coffee County, step by step?
- Ask Coffee County Planning and Zoning to confirm the parcel's district, minimum lot size, setbacks and proposed use48.
- If the parcel will use septic, obtain TDEC approval before grading a building pad or beginning construction21.
- Submit the required project information and obtain the building permit from Coffee County Codes141.
- 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 contractor26.
- Obtain a TDOT entrance permit for work on state highway right-of-way27.
- Arrange the required building inspections and have the TDEC Environmental Scientist inspect the septic system before it is covered1523.
What should you check before buying land in Coffee County?
Confirm the zoning district, minimum lot size and setbacks with Coffee County Planning and Zoning before choosing a building site48. Verify septic feasibility early because only about 27.7% of county soils lack severe conventional-drain-field limitations24. Ask the Highway Department about county-road access, while work on state highway right-of-way requires a TDOT entrance permit2827. A qualifying sewer utility may require connection when a building's lot abuts a public way containing its sanitary sewer29. For electrical service, written notice must show public sewer service, a septic application or an existing septic system30. Local floodplain review may be required before grading, fill or construction, but Coffee County's administering office remains unconfirmed31.
Watch-outs
- Do not apply the Tennessee state residential-permit fee table to a Coffee County project without checking locally; Coffee County administers its own building permits132.
- Coffee County's lot-size and setback tables differ for A-1 and non-A-1 districts, so identify the zoning district before judging whether a parcel is buildable48.
- A farm-related setback exemption does not by itself waive every building, zoning, septic or floodplain requirement19.
- Coffee County's RV, temporary-camping, tiny-home, minimum-dwelling-size and floodplain-development rules remain unconfirmed; ask Planning and Zoning about the parcel9.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
