Permits are required to erect, alter, move, enlarge, replace, demolish or repair a structure or building. Residents should verify that contractors have obtained proper permits for any work being done. Permits and inspections are required whether the work is done by a contractor or a homeowner. If permits are not obtained, the safety and economic value of the home, building or infrastructure could be affected. It could also delay selling a home or result in fines being assessed.
