Building Permits

Residents must obtain necessary building permits through Development Services before beginning any new construction or additions to existing buildings, including decks, fences or pools. Municipal codes also regulate sign installation, water softeners, air conditioners, swimming pools, fences, antennas, lawn sprinkler systems, driveways and accessory outbuildings.
