What it takes to legally install, replace or repair a garage door in Nashville-Davidson metropolitan government (balance) (Davidson County) — state licence, local permit, and the local news wire.
Tennessee requires a contractor licence at $25,000 and above and a separate Home Improvement licence for $3,000-$24,999 jobs in nine named counties; there is no garage-door classification, the closest being BC-6 Glass, Window and Door Construction.
