Do I need a permit for deck construction or replacement in Decatur?
Most likely yes. Deck construction or replacement usually requires a permit in Tennessee. Confirm the specifics with Decatur.
The state residential building permit covers new homes and additions of 30 square feet or more of interior space. Rule 0780-02-23-.01 lists additions of exterior space as renovation, so the state program itself does not permit a deck on a site-built home. Where your city or county enforces its own residential code, it sets the deck permit rules, and a permit is commonly required there. Confirm with your local codes office before you build. A site-built deck, porch, or stoop added to a manufactured or modular home does need a state Manufactured/Modular Site Work Permit where the state program applies. Any wiring added for deck lighting or outlets needs an electrical permit and inspection.
Local detail for Decatur: Tennessee's State Residential Building Code Enforcement Program covers Decatur, 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.
