In Culver City, the city's Building Safety Division handles permits, plan check and inspections, and it's the office that decides whether your job needs a permit. Its list of work that needs one names additions, remodels, ADUs, repairs and new construction but doesn't name driveways or patios, so before I price a job I look into what the division asks for at your address and tell you what I found. Where a permit is needed, the division's current estimate for plan check is about 15 to 20 business days from payment and routing, and that can change, so we set the start around it and can handle the concrete side of the paperwork or work with your architect or engineer.
Your price moves most with the parts you won't see, like how much old concrete comes out, how deep we dig out and pack the subgrade, the ground the slab sits on, and how far we wheel concrete when the truck can't reach the back of the lot. Size, thickness, rebar, the steel bars that hold the slab together if it cracks, and the finish come next, and the schedule turns on any permit, the weather and the curing wait, all of it listed in the written scope you get with your estimate. Ballona Creek carries runoff for a big part of the basin, but that tells you nothing about how water moves on your lot, so I check where yours runs and slope the slab away from the house. We're based in Malibu and do the same work in Santa Monica and the other cities around it.
