Do I Need a Building Permit?

Do you need to get an official stamp of approval before you remodel your basement, install a fence or replace a water heater? Yes you do!

A building permit is required for most construction projects whether it is to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure. A building permit is also required to erect, install, enlarge, alter, repair,
remove, convert or replace any electrical, gas, mechanical or plumbing system or cause any such work to be done. Once you've determined that you need a permit, please review any guides available, frequently asked questions or proceed to submit an application.
