Building permits in Unincorporated Henry County

Unincorporated Henry County does not issue residential building permits. Henry County passed a resolution opting out of the state residential building program, so no county or state residential building permit is required in the unincorporated county. An owner may voluntarily request a state building permit and SFMO inspection (Tenn. Code Ann. 68-120-101(b)(1)(D)) to obtain a certificate of occupancy. Zoning, septic and electrical rules may still apply.

That does not make the work unregulated. The construction standard still applies, trade licensing still applies, and separate approvals such as on-site sewage, floodplain development, and driveway access are handled by other offices. Below are the contact details for the office to ask, plus guides for the projects homeowners ask about most.

Tennessee has no statewide dollar-value permit exemption; whether a permit is required in Unincorporated Henry County and any cost thresholds are set by the local building department, not the state. The state residential building code applies to new construction and additions over 30 square feet, and cities or counties that keep their adopted codes current within seven years of the latest edition administer and issue their own permits locally. Where a local government does not maintain a current code, the State Fire Marshal's Office administers the residential permit program through authorized issuing agents and the state's online CORE portal. Always confirm the exact requirements and fees with the office that has jurisdiction over your property.

Permit FAQs for Unincorporated Henry County

Do I need a building permit in Unincorporated Henry County?
Henry County passed a resolution opting out of the state residential building program, so no county or state residential building permit is required in the unincorporated county. An owner may voluntarily request a state building permit and SFMO inspection (Tenn. Code Ann. 68-120-101(b)(1)(D)) to obtain a certificate of occupancy. Zoning, septic and electrical rules may still apply.
Who issues building permits in Unincorporated Henry County?
Nobody does. Unincorporated Henry County does not run a residential building permit program, which is why this page lists State Fire Marshal's Office, Residential/Electrical Contract Inspections (TN Dept. of Commerce & Insurance) as the office to contact rather than as a permit issuer. Your mailing city is not always the authority over your property, so confirm which jurisdiction you are actually in before assuming this applies to you.
What still applies in Unincorporated Henry County if there is no building permit?
The construction standard does. Work must still meet the Tennessee state-adopted building codes (the 2021 ICC family), and trade licensing rules apply regardless of whether a permit is issued. Separate approvals such as on-site sewage, floodplain development, and driveway access to a public road are handled by other offices and are unaffected. Ask State Fire Marshal's Office, Residential/Electrical Contract Inspections (TN Dept. of Commerce & Insurance) which of those reach your property before you start.
