Question 1

Do I need a permit for painting, flooring, new cabinets or countertops in Sunnyvale?

Accepted Answer

Usually no permit - this is finish work. California's code lists painting, wallpaper, tile, carpet, cabinets, countertops and similar finish work as not needing a building permit. If the job also moves plumbing, adds outlets or circuits, or removes a wall, that part needs a permit. Check with the Sunnyvale Permit Center - single-family homes before you start.

Question 2

Do I need a permit for kitchen or bathroom remodel in Sunnyvale?

Accepted Answer

Depends on the work - cosmetic updates usually don't; moving pipes, wiring or walls does. No permit for swapping cabinets, countertops, tile, flooring and paint. A permit is needed for new or moved plumbing, new circuits or outlets, new gas lines or venting, and removing or adding walls. Most full remodels need at least plumbing and electrical permits. Check with the Sunnyvale Permit Center - single-family homes before you start.

Question 3

Do I need a permit for plumbing repair (leak, clog, toilet) in Sunnyvale?
