Many home improvements like fencing and roofing do not need zoning approval but may need approval from other agencies. We must still sign the plans as being exempt from review. Work that requires a permit includes:
Accessory structures such as sheds, swimming pools, HVAC equipment, etc.
Interior or exterior modifications to your home including decks, additions, and garages
Paving for driveways (depending on size and location)
Use of your home for a private business or "home occupation"
