Do I need a permit for a concrete retaining wall or driveway in Calabasas?
A retaining wall under 3 feet tall needs no construction permit in Calabasas unless it's holding back extra weight, like a sloped yard or a driveway above it, and retaining walls that do need one are among the larger projects that need full plans. Driveways and patios aren't on the city's no-permit list, and the city's planning guidance says almost any exterior change, including garden walls over 42 inches, will require permits, with exterior work likely needing a zoning sign-off first. We check your job with the city before we put it on the calendar.
