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

Hardin County opted out of Tennessee's State Residential Building Code Enforcement Program, so the state does not run residential building permits for one- and two-family homes in unincorporated Hardin County.12 That opt-out does not by itself prove that no other county or specialized permit applies, and the county's department list shows no building or codes office, so ask Hardin County Government before you start.12 The opt-out applies to the statewide standards for one- and two-family dwellings; municipal building permit requirements can differ inside Savannah, Adamsville, Crump, Milledgeville and Saltillo1314. An owner or contractor may request a State Fire Marshal inspection for a home or addition in the opt-out area7. If the dwelling meets statewide construction safety standards, the State Fire Marshal can release a Certificate of Occupancy8. Tennessee's owner-builder exemption covers one residence for the owner's own use every two years, not a home for resale, lease or rent; a person hired for work costing $25,000 or more is not exempt from contractor licensing6.

Who issues building permits in Hardin County?

No state residential building permit office covers unincorporated Hardin County because the county is listed as opt out, and the county's own department list has no building, codes, planning or zoning office.11412 For parcel-specific local questions, call Hardin County Government at (731) 925-9078 or visit 465 Main Street, Savannah, TN 3837212. For an optional state construction inspection, the state list gives the Hardin County opt-out contact as 731-607-6395 and savinspector@yahoo.com14. TDEC, not the county or a town, issues septic permits and inspections for every address in Hardin County through the Jackson Environmental Field Office45. A driveway built or changed within state-highway right-of-way needs a TDOT entrance permit15.

Does Hardin County have zoning?

Hardin County is reported as having no county zoning in its unincorporated area, but we could not confirm that conclusion in an express county ordinance or no-zoning statement3. Ask Hardin County Government to verify the current status for the parcel before relying on the absence of county zoning12. Tennessee law authorizes counties to zone land outside municipal corporations, so a town's rules and any future county action are separate questions16. The county-zoning exemption for agricultural structures requires land devoted to agricultural uses and a structure incidental to the farm; it does not apply in the 100-year floodplain or within municipalities and has other location exceptions17. Minimum home size, setbacks, lot coverage and building height remain unconfirmed for unincorporated Hardin County; ask county government about each before closing12.

How do septic permits work in Hardin County?

TDEC, not Hardin County, administers septic permits and inspections through the Jackson Environmental Field Office45. A permit is required to install or repair a septic system and should be obtained before dirt work or construction of the building pad18. Mark the property lines and house location and mow or bush hog before the site visit; TDEC may request a detailed site plan or a soils map from a licensed soil consultant, and a complete application may take up to 45 days19. A conventional-system permit costs $400 through 1,000 gallons per day of design flow, while an alternative-system permit costs $500 at that flow; repair permits have no permit fee20. Only 17.3% of Hardin County soils are rated without severe limits for a conventional drain field, so make the site evaluation an early purchase contingency21. The installer must arrange final inspection before covering the system; approval produces a Certificate of Completion22.

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

We could not confirm a Hardin County rule that authorizes or prohibits long-term RV living, temporary camping, tiny-home occupancy, manufactured homes or accessory dwellings on unincorporated land. The absence of a mandatory residential building permit does not answer occupancy, sanitation, floodplain or utility questions22324. Inside Savannah, occupying or servicing a travel trailer outside a properly designated travel-trailer park is prohibited; unoccupied travel-trailer storage is excepted10. That Savannah rule does not establish the rule for unincorporated Hardin County or another municipality. Ask Hardin County Government about the proposed use and parcel location before moving a unit onsite12. A single-family domestic waste system requires a Division of Water Resources construction permit even though it does not require a UIC permit23. Before electrical service is processed, the electrical inspector needs written confirmation of public sewer service, a septic application or an existing septic system11.

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

  1. Confirm that the parcel is outside a municipality and ask Hardin County Government about zoning, setbacks, floodplain status and county-road access32412.
  2. If land will be divided for septic-served lots, submit the required TDEC subdivision evaluation, survey and soils map; the stated subdivision definition excludes divisions where every resulting tract is at least 5 acres25.
  3. Apply to TDEC for the septic permit before dirt work or the building pad; mark the property lines and house location and prepare the site for the visit1819.
  4. Obtain a TDOT entrance permit before constructing or changing a driveway in state-highway right-of-way15.
  5. Decide whether to request the voluntary state inspection and possible Certificate of Occupancy78.
  6. Give the electrical inspector written sewer or septic documentation before requesting electrical service, then have the septic installer schedule final inspection before covering the system1122.

What to check before you buy land in Hardin County

Hardin County has 71.6% of its land at a slope of 15% or less and a 69.3% wooded share, but parcel-level terrain and clearing needs still require an onsite look2627. Only 17.3% of county soils rate without severe limits for a conventional drain field, so make satisfactory TDEC septic approval a purchase contingency2118. Floodplain requirements are managed locally and may require review before construction, fill, grading, excavation or placement of a manufactured home24. The nearest city of 100,000 or more is about 91 miles from the county center, which can affect supply and service trips28. The typical effective property-tax rate is 0.4%, and the median annual property-tax bill is $6662930. Confirm legal access and private-well requirements before closing; we could not confirm those parcel-specific rules.

Watch-outs

  • No state residential building permit applies in unincorporated Hardin County, but the opt-out does not prove the county has no permit of its own, and county zoning is only reported as absent; verify the parcel with Hardin County Government.1312
  • Only 17.3% of Hardin County's soils are free of severe limitations for a conventional septic drain field, so don't assume a standard system will pass without a TDEC site evaluation21.
  • Savannah prohibits occupying a travel trailer outside a designated travel-trailer park, while the rule for unincorporated Hardin County remains unconfirmed10.
  • Floodplain development requirements are local and may cover construction, fill, grading, excavation, manufactured homes and accessory structures; ask Hardin County Government who reviews the parcel before work begins2412.
