You need a building permit to construct, enlarge, alter, repair, move, remove, or demolish any building, structure, or any part thereof, or any equipment, device or facility therein or thereon and if the work entails changes in the use or occupancy of the building. A structure can be limited to a driveway, patio, deck, walkway, fence, retaining wall, shed, gazebo, trellis, antenna tower, fountain, spa or pool. If you are unsure if a permit is required, please contact the Building Division and direct your question to Chief Structural, Electrical, Mechanical, or Plumbing Inspector.
