The answer is ALMOST ALWAYS!
The North Carolina State Building Code states, "No person, firm or corporation shall erect, construct, enlarge, install, alter, repair, move, improve, remove, convert or demolish any building, structure, or service system without first obtaining a permit for such from the Inspections Department having jurisdiction."
In other words, a permit is required anytime work is done on a building or structure, or the systems serving the structure (including plumbing, mechanicall and electricall wiring) with a few exceptions.
Examples of everyday projects requiring permits include:
- Converting a residence to a business.
- Constructing a deck, screened porch, or sunroom.
- Installing an irrigation system.
- Installing a swimming pool.
- Adding a ceiling fan.
- Finishing an attic or basement.
- Replacing a furnace or air conditioner.
- Replacing water heaters.
- Installing gas logs, attic fans, skylights
