Building permits in Chattanooga — Southeast Tennessee's largest city and the Hamilton County seat — are issued by the Land Development Office, which handles building and trades permits, site development, zoning, and floodplain management. Chattanooga adopted a new zoning code effective December 18, 2024.
This Chattanooga building permit guide covers what requires a permit, how the Land Development Office works, the OpenGov portal, fees, trade permits, and inspections — so your Chattanooga project starts clean.
Chattanooga and Hamilton County are separate permitting jurisdictions. The City of Chattanooga's Land Development Office handles permits within city limits. Hamilton County Building Inspections (4005 Cromwell Road) handles permits for unincorporated Hamilton County and some municipalities by agreement. Confirm jurisdiction before applying.
What requires a building permit in Chattanooga?
Under the International Codes as adopted by the City of Chattanooga, a permit is required before constructing, enlarging, altering, repairing, moving, demolishing, or changing the occupancy of most structures. Common triggers include:
Permit required
- New residential and commercial construction, additions
- Structural and load-bearing alterations
- Reroofing, windows, doors, and exterior changes
- Electrical service upgrades and most wiring work
- HVAC installations and changeouts
- Plumbing alterations, repipes, and water heaters
- Decks, pools, fences, accessory structures, and signs
- Change of occupancy or use
Typically exempt
- Painting, flooring, cabinetry, and cosmetic work
- One-story detached accessory structure ≤ 200 sq ft
- Replacement of existing fixtures (like-for-like swaps)
- Minor repairs not affecting structural or safety systems
Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get the permit issued before starting work. Building without one exposes the owner to penalties and stop-work orders. Note that exemption from a building permit does not exempt a project from zoning requirements — confirm edge cases with the building department.
Who handles permitting in Chattanooga?

Chattanooga trade permits
Electrical, plumbing, mechanical, gas, and excavation permits are filed separately through the OpenGov portal. Each requires a TN-licensed trade contractor and a City of Chattanooga trade license.
Electrical permits
Required for service upgrades, panel work, solar PV, and most wiring — performed by a TN-licensed electrical contractor with a Chattanooga electrical license.
Plumbing permits
Required for new plumbing, repipes, water heaters, and gas piping — performed by a TN-licensed plumber with a Chattanooga plumbing license.
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, ductwork, and refrigeration — performed by a TN-licensed mechanical contractor.
Miscellaneous & specialty
Reroofs, decks, pools, fences, signs, and accessory structures are permitted separately. Residential Repair Replace (BRR) permits cover like-for-like replacements. Land-disturbing permits (LDPs) follow the new zoning ordinance effective December 18, 2024.
Verify your contractor's license. Tennessee requires a state contractor license issued by the Tennessee Board for Licensing Contractors (under the Department of Commerce & Insurance / TDCI) for projects valued at $25,000 or more. Separate trade licenses are required for electrical (CE), plumbing, and HVAC/mechanical work. Homeowners may pull their own permit for personal-use construction once every 24 months under TCA § 62-6-103 — but the project must still meet all code and inspection requirements. Verify licensure at tn.gov/commerce/regboards/contractors.
