Unincorporated Sullivan County

Sullivan County says building permits are required for all types of residential housing including new homes, single-wide mobile homes, double-wide mobile homes, modular homes, additions, carports, garages, storage buildings, gazebos, pools, decks, roofs, and interior remodeling jobs. Zoning compliance permits are required for multifamily and planned developments and for non-residential structures such as commercial buildings, churches, signs, and manufacturing uses.

Note: No explicit county exemption list was found on the reviewed Planning and Codes page, application packet, or zoning resolution excerpts reviewed here.

Building code

County page states the county adopted the 2018 International Residential Code and the 2018 Energy Code effective April 1, 2018 for one- and two-family residential work. The zoning resolution also governs zoning compliance permit requirements.

Permit validity

The county permit application states the permit expires after 180 days from issuance and or between inspections if not exercised.

Owner-builder

The county application asks whether the property owner is acting as the general contractor. No separate public owner-builder affidavit or special owner-builder limitation was found in the reviewed county materials.

Contractor requirements

Contractor company name and state license number are requested on the county application. Electrical permits are state-issued. Tennessee state licensing rules apply where project value or trade classification requires it.
