Permits & Site Prep
General information only. Codes and requirements vary by county and city, so always confirm with your local building department.
Permits
- Many Tennessee counties and cities require a building permit for accessory buildings over a certain size. Others have limited or no residential building codes in unincorporated areas. It truly varies.
- Zoning sets setbacks, height limits and building size limits relative to your home or lot.
- Buildings used for agriculture may qualify for different treatment in some counties. Ask your county.
- Living space (barndominiums) and commercial buildings usually require engineered plans and inspections.
- HOA covenants can be stricter than county rules.
- Electrical work usually requires a separate permit and state electrical inspection.
Site preparation
- Choose a level, well-drained location, and plan where roof water will go
- Grading and compacted gravel pad if needed
- Access wide and firm enough for delivery trucks and equipment
- Locate utilities before digging (call 811)
- Keep required distances from septic fields, wells and property lines
The builders you're matched with can help with placement and typical requirements, and many can provide drawings and specs for your permit application. The property owner is responsible for getting permits.
