Shed Installation Permits in Chattanooga

Local Rule

City of Chattanooga Land Development Office; Tennessee Building Code (2018 IRC-based, Chattanooga-amended, effective 26-may-2023)

Chattanooga follows a 200-square-foot threshold closer to the Tennessee state standard for a shed building permit; however, the city requires every homeowner to complete an accessory structure questionnaire for any shed regardless of size, which determines whether the shed's placement complies with city ordinances, easements, and setback requirements. Chattanooga sits on karst limestone terrain, giving it an 18-inch frost depth requirement shallow by northern standards but deep enough that shed foundations and posts must bottom out below that depth in undisturbed soil, with no surface mounting. Sheds in a historic district may need a Certificate of Appropriateness from the Historic Zoning Commission.

How This Compares to Hamilton County

Chattanooga's own rule is shown above (No permit under 200 sqft). Here is the separate rule that applies at the county level, for context:

Hamilton County Building Inspections

Tennessee's three-tier code system (exempt, non-exempt, and opt-out jurisdictions) makes this county harder to pin down: the confirmed primary-source rule found only covers accessory dwelling units over 800 sq ft, not a general shed exemption threshold. Chattanooga (a city within the county) uses a 200 sq ft threshold, but that is separate from the unincorporated county rule. Confirm directly with Hamilton County Building Inspections.
