Do I need a permit for screen enclosure or pool cage in Unincorporated Knox County?
It depends. Whether screen enclosure or pool cage needs a permit in Unincorporated Knox County comes down to the details of your project.
A screened porch or patio enclosure attached to the home is typically treated as a structural addition and needs a permit; a freestanding open screen frame may fall under a lower threshold, so confirm locally. If the enclosure adds a roof or is later converted to conditioned living space, additional structural and energy-code review applies. An enclosure attached to the house is a structural addition to the dwelling rather than a freestanding accessory structure. Attached enclosures require a building permit, and the footings and the attachment to the existing structure are normally inspected before they are covered up. In Knox County, permits outside the cities are handled by the Knox County Codes Administration and Enforcement office, reachable on 865-215-2325 at https://www.knoxcounty.org/codes/. Its online permit portal is https://epw-permitsubmit.knoxcountytn.gov/. Where a Tennessee local government has neither taken on residential code enforcement itself nor opted out by a two-thirds vote, the State Fire Marshal's Office runs the residential permit and inspection programme instead. Confirm whether Knox County enforces its own code or the state does. An attached enclosure is a structural addition, so expect a plan review and a footing and attachment inspection.
