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

Yes. Jefferson County requires a building permit for a garage, new building or addition, including any new non-portable structure or addition; the stated exception is a structure used strictly for agriculture112. Jefferson County has adopted the 2018 International Residential Codes, although an older answer on the same county page still refers to the 2012 code2. Before the county will issue a house permit, the application must include the warranty deed, survey or plat, septic approval, and the square footage of the home and garage13. Ask the Building Department which code edition governs a specific design if the older page language affects your plans.

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

The Jefferson County Building Department reviews plans and handles building permits at 202 W. Main Street, Dandridge, TN 37725, phone 865-397-06408. Submit two copies of the plans, blueprints or drawings; the published plan-review wait is two days, though some plans take longer13. The building permit is purchased at the courthouse in the Zoning Office after septic approval144. A contractor application requires the state and county licenses, liability and workers' compensation insurance, and a driver's license13. Property-specific zoning questions go to the Zoning Department at the same address, phone 865-397-4414156.

Does Jefferson County have zoning?

Yes. Jefferson County administers local zoning districts, maps, permitted uses and subdivision regulations outside incorporated municipalities3616. Confirm the parcel's district with the Zoning Department before designing a site plan6. In A-1 and R-1, the front setback is 30 feet; A-1 side and rear setbacks are 10 feet, while R-1 side and rear setbacks are 12 feet17. The county says setbacks can depend on property size, so obtain a parcel-specific determination17. For an A-1 second tract or home, the stated minimum is 40,000 square feet with Health Department septic approval, and all lots need 50 feet of county-road frontage9. A licensed surveyor must cut off a tract for a second home9.

How do septic permits work in Jefferson County?

Jefferson County Environmental Health administers septic permits and final approvals, and new construction needs septic approval before the building permit74. A subdivision lot application needs the lot number and subdivision name; other property needs a recorded plat map and soil map, with the proposed house site's four corners staked before application4. The county septic permit fee is $500, payable to the Jefferson County Trustee4. After installation, the installer must schedule final approval before covering the system, and the inspection requires verification of the building permit and 911 address18. Only about 27.9% of county soils rate free of severe limits for a conventional drain field, so make the site evaluation an early purchase contingency19.

Can you live in an RV or tiny home on your land in Jefferson County?

Jefferson County's published material does not confirm a complete countywide rule for living in an RV or every form of tiny home; ask the Zoning Department about the parcel and proposed use15. The county does say that a structure intended for residential occupancy must meet the residential codes adopted in that jurisdiction8. Its tiny-home construction guide rejects park-model recreational vehicles and converted yard barns, storage buildings, shipping containers or other pre-built structures as dwellings20. That guide also describes permanent-foundation construction and at least one habitable room with 120 square feet of clear floor area20. Do not treat those construction standards as an answer about temporary camping or RV occupancy, which the county materials reviewed here do not resolve.

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

  1. Ask the Zoning Department for the parcel's district, permitted uses and setbacks before placing the house617.
  2. Secure access: a new driveway or road connecting to a county road needs a free county permit and may require a drainage tile; a state-highway driveway needs a TDOT permit2122.
  3. Apply to Environmental Health for septic approval before the building permit4.
  4. Submit two plan copies and the required deed, survey or plat, septic approval, and home and garage square footage to the Building Department13.
  5. If you act as owner-builder, supervise every phase and use licensed subcontractors; hiring a general contractor requires the permit to be reissued to that contractor513.
  6. Obtain the 911 address after the building permit, then have the septic system inspected before it is covered1418.
  7. Ask the Building Department for the project-specific inspection schedule and certificate-of-occupancy requirements, which we could not confirm from the published county material8.

What to check before you buy land in Jefferson County

Confirm the parcel's zoning district and permitted use with the Zoning Department, then verify its setbacks, subdivision status and road frontage617169. Check septic feasibility early because only about 27.9% of county soils rate free of severe limits for a conventional drain field19. Determine whether access meets a county road or state highway: county-road connections require a county permit and may need a drainage tile, while state-highway access requires a TDOT permit2122. Jefferson County's effective property-tax rate is about 0.5%, the typical annual bill is near $990, and USDA farmland value is about $6,648 per acre101123. Ask Environmental Health about private-well and off-grid sanitation requirements, and ask the Zoning Department about RV, temporary-camping, floodplain and accessory-dwelling rules; we could not confirm those parcel-level answers.

Watch-outs

  • Jefferson County's tiny-home guide rejects park-model recreational vehicles and converted yard barns, storage buildings and shipping containers as dwellings, but the countywide rules for RV living and temporary camping remain unconfirmed; ask the Zoning Department before buying2015.
  • A Jefferson County house needs septic approval before the building permit, and the installed septic system must pass final inspection before it is covered418.
