Building permits here come from the city's Permit Services Center, which covers building, altering, demolishing or repairing a building or structure, so whether your driveway, patio or wall needs one is a question for that office. An older city handout gives examples, such as a fence over seven feet tall needing a permit. Where a permit applies, plan review has to be finished and every city approval in hand before it's issued, and the work is inspected in stages up to a final sign-off, so the city's timing sets part of your schedule. Any contractor working here needs a Santa Monica business license, and the city's application for it asks for a California state contractor's license number, so ask to see both before you hire.
Before I price a job, I check what the city asks for at your address and tell you what I found, and where approvals are needed we plan the start around them and handle the concrete side of the paperwork or work with your architect or engineer. The price usually turns on access and what has to come out first, because a narrow side yard or an alley garage can mean wheeling concrete in or bringing a pump, and an old slab has to be broken out and hauled away before we dig the base. Size, thickness, steel and finish do the rest, and a broom finish, a light texture that gives your shoes some grip, costs less than stamped work. We plan jobs the same way in Culver City and farther out in Camarillo, and your estimate puts each of these on its own line.
