Building Permits

Building Permits are for structural alterations. They are required to add a room or create additional living space, add a window or door, add or remove walls, and build a stairway or carport. Depending on the extent of the work, a permit may be required to build a deck, porch cover, shed, retaining wall, or when re-roofing. Some of these permits may also require a review from the Planning Department.
