Permit Required
Knox County Codes Administration issues building permits for accessory structures; one-story detached buildings under 120 sq ft are exempt from a building permit but must still meet zoning. Detached accessory structures are capped at 3,000 sq ft and 2 stories. Online permitting is available.
Wind Zone
Ultimate design wind speed — verify with engineer
Snow Load
Ground snow load, minimum design
Typical Setbacks
Varies by zoning district; verify with Codes Administration and zoning before placement.
HOA Risk
Moderate — many West Knox/Farragut subdivisions have active HOAs with their own accessory-structure rules; rural tracts mostly do not.
Pro Tip for Knox County
A site plan showing the structure's distance to property lines, septic, and easements is expected up front; bringing one to your first visit avoids a return trip.
