Cumberland County, Tennessee requires a county building permit for residential new construction and county-regulated commercial work, issued by the Cumberland County Codes Department under codes effective in 202412. Zoning varies by jurisdiction: Crossville has limited subject-specific zoning rather than general residential, commercial or industrial districts, and we could not confirm a general county zoning ordinance for unincorporated land34. Septic permits for every parcel come from TDEC, not the county or Crossville5.

Do you need a building permit in Cumberland County, Tennessee?
Yes. Cumberland County requires a building permit for residential new construction and for county-regulated commercial work1. A new home also requires plumbing and mechanical, HVAC or gas-piping permits1. Cumberland County's residential and commercial codes took effect in 2024; residential work uses the 2018 International Residential Code with local amendments and deletions2. The county inspects new residential construction but excludes residential remodels and additions from the inspection scope stated in the adopting resolution; specified commercial construction and occupancy-change work is inspected6. Agricultural buildings, plus accessory buildings, garages and decks that are not part of new residential construction, are exempt from permits under that resolution2. Confirm the exemption with the Codes Department before work begins.
Who issues building permits in Cumberland County, and how do you reach the Codes Department?
The Cumberland County Codes Department is the local building office for county-regulated work outside the City of Crossville11. Call (931) 710-5727, email codes@cumberlandcountytn.gov or visit 1760 S Main Street in Crossville11. Applications may be filed there or through the county's online permit portal12. A complete application may require address verification, a septic permit and layout, construction plans, and a homeowner affidavit when applicable; a state-licensed general contractor must establish an account before pulling permits12. County fees vary by project valuation and square footage; a $100 re-inspection fee applies after two no-charge re-inspections13. An owner-occupant may act as general contractor on one personal residence every two years, but the home cannot be for resale, lease or rent, and hired contractors must be licensed9. Inside Crossville the city uses ICC building codes, so confirm with the city codes department before assuming the county's rules apply14.
Does Cumberland County have zoning, and who sets zoning rules?
Land-use controls vary across Cumberland County, so the parcel's jurisdiction matters3. We could not confirm a general countywide zoning ordinance for unincorporated land; ask the Planning Commission at 931-979-2170 about the parcel1516. Crossville has zoning for airports, floodplains, signs, mobile homes and mobile-home parks, but no general residential, commercial or industrial districts417. County subdivision rules apply outside the Crossville planning jurisdiction and the municipalities of Crab Orchard and Pleasant Hill18. Within that county planning jurisdiction, subdivision lots have road setbacks of 30, 40 or 50 feet depending on road class and side and rear setbacks of 10 feet19. Residential subdivision minimum lot area ranges from 6,000 square feet with public water and sewer to 2 acres with private water and septic20.
Who issues septic permits in Cumberland County, and how do they work?
TDEC handles septic permitting in Cumberland County, not the county Codes Department5. A state septic permit is required to construct, modify or repair a system serving residential, commercial or industrial property7. Tennessee advises obtaining the septic permit before starting dirt work or construction of any building, including the building pad21. Obtain the septic approval early also because the county permit application may require the septic permit and layout12. After installation, the installer must arrange TDEC's final inspection before covering the system; an approved installation receives a Certificate of Completion22. Only 4.6% of Cumberland County soils rate free of severe limitations for a conventional drain field, so establish a workable system and reserve area before committing to a homesite10. In county-regulated subdivisions, lots using private water and private sewage disposal generally require at least 2 acres, subject to the Environmentalist and site conditions20.
Can you live in an RV or tiny home on your land in Cumberland County?
We could not confirm a Cumberland County rule for long-term RV occupancy, temporary camping, tiny-home occupancy or manufactured-home occupancy on private land. Ask both the Cumberland County Codes Department and Planning Commission about the exact parcel and proposed use before placing or occupying a unit1116. Crossville separately regulates mobile homes and mobile-home parks, so land inside the city needs a city-specific answer4. A tiny home used as a dwelling should not be treated as permit-exempt merely because it is small: Cumberland County requires permits for residential new construction in the county's jurisdiction1. Any septic system must go through the state permit process7. We could not confirm a general minimum dwelling size or rules for off-grid sanitation; ask the two county offices before buying or building.
Building a home in Cumberland County: what are the steps, in order?
- Confirm whether the parcel is in the county planning jurisdiction, Crossville, Crab Orchard or Pleasant Hill because land-use rules vary3.
- If land is being divided, submit the required plat before recording or selling a lot and verify the applicable lot size, setbacks and access18201923.
- Have TDEC approve the septic system and obtain the layout needed for the county application712.
- Assemble the plans and homeowner affidavit if applicable, then apply online or in person129.
- Obtain the building, plumbing and mechanical permits required for a new home1.
- Schedule the required inspections; the county will not schedule them without a permit24.
- Pass final inspection and receive the certificate of occupancy before moving in furniture or occupying the home25.
What should you check before buying land in Cumberland County, Tennessee?
Start with septic suitability: only 4.6% of Cumberland County soils rate free of severe limitations for a conventional drain field10. Confirm the parcel's jurisdiction and whether subdivision review applies, because county subdivision rules exclude the Crossville planning jurisdiction, Crab Orchard and Pleasant Hill18. New subdivision lots in the county planning jurisdiction generally need at least 50 feet of road frontage, while a qualifying cul-de-sac lot may have 30 feet; a narrow access easement must meet separate conditions23. Where public water or sewer is reasonably accessible in a county-regulated subdivision, the subdivider must connect each lot, and a sewer line within 300 feet triggers a subdivision sewer connection requirement26. For a driveway on state right-of-way, TDOT requires a permit27. Cumberland County's median property-tax bill is about $699 per year at an effective rate near 0.3%2829. Floodplain development in Tennessee is managed by the local community's floodplain administrator, the city's inside city limits and the county's outside them30.
Watch-outs
- Do not begin work before permits are issued: Cumberland County will not schedule required inspections without a permit24.
- Do not occupy the structure or move in furniture until it passes final inspection and receives a certificate of occupancy25.
- TDEC must inspect a septic installation before it is covered, and approval results in a Certificate of Completion22.
- Crossville, Crab Orchard and Pleasant Hill are outside the county subdivision regulations' stated jurisdiction, so do not apply county subdivision lot sizes or setbacks to property there18.

- 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.
