Some projects that do not require a permit include cosmetic changes such as paint, wall paper, floor covering, cabinets, countertops, tiled backsplash, vanities, trim, baseboard, interior doors, fences, retaining walls less than 4 feet in height, and sheds/accessory structure 200 square feet or less.
If you are unsure whether you need a permit, contact the Building Safety Division and explain what you will be doing. Staff will advise you if the work you are doing is regulated and whether or not a permit is required.
