Permits

Do you need a permit to remodel a kitchen or bathroom in San Jose?

By ProRock Remodeling · CSLB #1154078 · Updated October 8, 2026

Short answerIt depends on what you change. The City of San Jose says cosmetic-only work — like new cabinets or countertops with no utility changes — typically does not need a permit. If the remodel involves electrical, plumbing, mechanical or structural changes, a building permit is required.

The rule in one line

If you're only replacing finishes, you usually don't need a permit. If you're changing anything that runs through the walls or holds the house up, you do.

Other Bay Area cities

Palo Alto, Sunnyvale, Mountain View, San Mateo, San Francisco and other cities each run their own building departments with their own forms and fees. The same principle usually applies — utilities and structure need permits — but always check the local rules for your address.

Frequently asked questions

Do I need a permit to replace kitchen cabinets in San Jose?

Usually not. The City of San Jose treats cabinet or countertop replacement with no utility changes as cosmetic work, which typically does not require a permit.

Do I need a permit to remodel a bathroom in San Jose?

If you move or add plumbing, add electrical circuits, change ventilation or touch walls and structure, yes. A purely cosmetic refresh usually does not.

What happens if I remodel without a required permit?

Unpermitted work can create problems with inspections, insurance and resale. It may need to be opened up and inspected later.
