Do I need a permit for pergola or trellis in Mason?
It depends. Whether pergola or trellis needs a permit in Mason comes down to the details of your project.
The state residential permit program does not require a state permit for detached structures that are not used for living purposes, and it treats additions of exterior space as renovation, so the state program does not permit a pergola. Where your city or county enforces its own code, its rules decide. Attaching the pergola to the house, adding a solid or louvered roof, or building it large or tall makes a local permit more likely. Wiring for lights, fans, or motorized louvers needs an electrical permit and inspection.
Local detail for Mason: Tennessee's State Residential Building Code Enforcement Program covers Mason, so residential building permits are bought from the State Fire Marshal's Office (online through CORE) and inspected by a state deputy inspector, not a local department.
