Kitchen and bathroom remodeling in Cupertino, CA: permits, inspections and what to expect

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

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

In most cases, yes. Cupertino's Building Division has a written Residential Kitchen/Bath/Laundry Remodel Policy, and its starting point is simple: a building permit is required for kitchen, bath and laundry remodels. The one carve-out is narrow. If you are only installing cabinets and/or replacing countertops, and you are not touching electrical, plumbing, mechanical systems or existing walls, that work can proceed without a permit. The City's FAQ similarly lists painting, tiling, carpeting, cabinets and countertops as exempt finish work, while noting that replacing plumbing fixtures needs a plumbing permit.

Translation for the Monta Vista ranch house or the Rancho Rinconada cottage: new countertops on the existing cabinets are fine. Move the sink, add a circuit for an induction range, take out the wall between kitchen and dining room, or swap a tub for a walk-in shower, and you are in permit territory.

When in doubt, the City's own rule of thumb applies: work not specifically listed as exempt requires a permit. Skipping it is a poor bet, because the City notes that permit fees are doubled when work started without one.

What goes into a Cupertino remodel permit application?

The City's remodel policy lists what the Building Division expects to see. A typical submittal includes:

• A completed building permit application
• Dimensioned existing and proposed floor plans showing walls, windows, doors, cabinets, adjacent rooms, and smoke and carbon monoxide alarm locations
• A ceiling plan with ceiling heights and any ceiling-level electrical or mechanical work
• A structural framing plan if any walls are removed or relocated
• Plumbing, mechanical and electrical plans (receptacles, fixtures, switching, ventilation)
• Energy compliance documentation (the CF1R-ALT form)
• An owner-builder disclosure form, if the homeowner is pulling the permit

All drawings must be signed by whoever prepared them. Applications and fee payments go through the City's online permit portal (Accela Citizen Access), and the Building Division also offers limited over-the-counter plan review hours at City Hall on Torre Avenue. If you are planning a bathroom in parallel, our bathroom remodel planning guide covers the decisions to make before drawings start.

How do inspections work in Cupertino?

Every issued permit requires inspections, and the number depends on the scope of work. Inspections are requested through the same online portal or by phone, with the permit number, address, inspection type and preferred date. On inspection day, the City sends a confirmation email with a two-hour arrival window, and the daily schedule is posted online early that morning. Inspectors work weekdays only.

One Cupertino detail that trips people up: the City will not schedule a final inspection until every contractor on the job holds a City of Cupertino business license, in addition to a California contractor's license. Before hiring anyone, it is worth taking two minutes to check the contractor's state license and ask about their Cupertino business license.

Why do so many Cupertino homeowners remodel instead of moving?

Cupertino's highly regarded schools keep families in place, and much of the housing stock is mid-century: single-story ranch homes, a scattering of Eichlers, and neighborhoods like Garden Gate and Seven Springs where kitchens were sized for a different era. Rather than trade a good school assignment for a bigger mortgage, many owners open up the kitchen, add a second sink to the primary bath, or rethink a hallway bathroom that has been serving three kids and one very patient parent. Older homes can also hide surprises behind the drywall, which is one more reason a permitted, inspected job is the safer route. You can see finished kitchens and bathrooms in our project gallery.
