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

Yes. Sevier County requires a residential building permit through its Planning & Zoning / Building Department, with applications made through MyGovernmentOnline1. The permit office supplies the required inspection list when it issues the permit; projects using a third-party inspector must then allow Sevier County 10 days to review inspection reports before work proceeds9. A Tennessee owner may build one residence for personal use under an owner-builder permit once every two years, provided the home is not for sale, lease or rent6. Anyone the owner pays more than $25,000 is treated as the prime contractor and must be licensed and obtain the permit10.

Who is the Sevier County building and zoning department, and how do you reach them?

The Sevier County Planning & Zoning Department is the first stop for residential building permits and zoning questions. The office is at 227 Cedar Street, Sevierville, TN 37862; call 865-453-3882 or email [email protected]8. New residential building-permit applications use MyGovernmentOnline8. Planning Commission and Board of Zoning Appeals submissions must reach the department at least 21 days before the scheduled meeting8. Ask the department to identify the parcel's zoning district, overlays, required plans and inspection path before paying for final construction drawings. County building-permit fees were not confirmed in the available official material, so request a project-specific fee estimate from the department.

Does Sevier County have zoning, and what does it mean on steep ground?

Sevier County administers zoning in the Sevier County Planning Region through Planning & Zoning and the Board of Zoning Appeals2. Only 22.3% of county land has a slope of 15% or less, and the county publishes Critical Slope and Hillside Overlay maps, so a buildable-looking mountain parcel may need additional review118. We could not confirm the parcel-level setbacks, lot coverage, height limits or minimum lot size; ask Planning & Zoning for the district rules and applicable overlay map. Tennessee limits county zoning of a farm structure that is incidental to an agricultural enterprise, but that protection has exceptions near certain highways, airports and parks and in the one-hundred-year floodplain12.

How do septic permits work in Sevier County?

Sevier County Environmental Health handles septic applications because Sevier is a Tennessee contract county5. Obtain the septic permit before dirt work or construction, including the building pad; an alternative system also requires an extra-high-intensity soils map prepared by a Tennessee-licensed soils consultant3. The county septic-permit fee is $3003. Online applications are available through MGO Connect for septic permits, repairs, well-water tests, inspection letters and site evaluations, while the county instructions say payment remains by cash or check in person or by mail1314. A failed initial final inspection carries a $100 re-inspection fee15. Only 6.9% of county soils rate free of severe limits for a conventional drain field, so settle the approved system area before fixing the house location4.

Can you build a tiny home or live in an RV on your land in Sevier County?

Sevier County Environmental Health lists 1,200 square feet for a one-bedroom home and 1,500 square feet for a two-bedroom home in its septic and site-evaluation materials; the available fact does not establish a general zoning minimum for every dwelling7. We could not confirm a county rule for long-term RV occupancy, temporary camping or tiny-home occupancy, so ask Planning & Zoning how the parcel's district treats the proposed unit and use8. Do not treat an overnight rental as ordinary residential occupancy: Sevier County defines a transient rental as occupancy of a single dwelling unit for 30 days or less, requires the proposed occupancy load on its use form, and requires Fire Marshal operational permits before overnight renting16.

Building a home in Sevier County: the steps, in order

  1. Ask Planning & Zoning to confirm the zoning district, overlays and required plans for the parcel28.
  2. Apply to Environmental Health for septic approval before dirt work or construction on a septic-served site3.
  3. Fix the approved septic area, bedroom count and house location before finalizing the plan; Environmental Health lists 1,200 square feet for one bedroom and 1,500 square feet for two bedrooms7.
  4. Submit the residential building-permit application through MyGovernmentOnline1.
  5. Follow the inspection list issued with the permit; allow the county 10 days to review reports if using its third-party inspection process9.
  6. Provide written sewer or septic status before the electrical inspector processes new-service approval17.
  7. Obtain a TDOT entrance permit before work on a driveway within state highway right-of-way18.

What to check before you buy land in Sevier County

Confirm a usable house site and septic area: only 6.9% of Sevier County soils rate free of severe conventional-drain-field limits, while only 22.3% of county land has a slope of 15% or less411. If land will be divided for development using septic, a survey and soils map precede the subdivision evaluation; division into two or more parcels is excluded from that rule when every parcel is at least 5 acres19. The county evaluation fee is $75 per lot plus $75 per existing home19. Check legal road access and whether a state-highway entrance permit applies18. Also verify water source, floodplain status and private-well requirements: a county well-water-test application exists, but we could not confirm a well-construction permit rule13.

Watch-outs

  • Do not grade a building pad before septic approval; Sevier County says the septic permit should come before dirt work or construction3.
  • A failed initial septic final inspection triggers a $100 re-inspection fee15.
  • Electrical-service processing requires written notice of public sewer service, a septic-permit application or use of an existing septic system17.
  • Sevier County overnight rentals require Fire Marshal operational permits before renting begins16.
