Kitchen and Bathroom Remodeling in Los Altos: Permits, Design Review and Inspections

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

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

Yes. Los Altos treats kitchen and bath remodels as permitted work, with building, electrical, plumbing and mechanical requirements reviewed by the Building Division. The city's kitchen remodel handout is clear on timing: demolition may begin only after plans have been reviewed and approved and permit fees have been paid.

Plans do not have to be stamped by a registered design professional, but the city says they must be drawn to a professional quality. The floor plan needs a wall legend showing existing, new and removed walls. If structural changes are involved, the plans examiner may require calculations from a licensed architect or engineer.

How do you apply for a remodel permit in Los Altos?

Los Altos takes building permit submittals by email, not at the counter. The city's permit submittal page says hard copy submittals will not be accepted at City Hall. Here is the process in short:

1. Email the completed building permit application and documents to bldpermit@losaltosca.gov.
2. Send the full plan set as one unsecured PDF, with supporting documents like energy forms as separate PDFs. Each file can be up to 250 MB.
3. Allow up to 5 business days for staff to confirm the submittal is complete.
4. Once accepted and paid, plans are routed for review. You get a comment letter, and resubmittals need a response letter plus revised plans with changes clouded.
5. Approved permits and plans are emailed back. Print them and keep them on site, because the city will not perform inspections without approved documents on site.

The city's 2020 kitchen handout still mentions paper plan sets; follow the current email process instead.

What code items does Los Altos look for in a kitchen remodel?

The handout lists specific items plan checkers and inspectors look for. Codes change every few years, so confirm current requirements.

Does a remodel in Los Altos need design review?

Los Altos applies single-family design review to projects with exterior alterations, additions or new construction in the R1 district. A remodel that stays inside the walls generally does not trigger it. New windows, a skylight, a relocated exterior door or a small bump-out for a bigger pantry can, so talk to the Planning Division before finalizing the design.

Homes designated as a Historic Landmark or Historic Resource on the city's Historic Resources Inventory have their own rule: all exterior changes require review. The Historical Commission handles that review, though minor residential improvements may get administrative approval from the Community Development Director.

What inspections should you expect?

The city requires inspections before any framing, electrical, plumbing or duct work is covered up. For kitchens and baths, add inspections for exterior waterproofing or lath where applicable, sheetrock, and a final gas test before appliances are connected. A final inspection closes out the permit.

• Scheduling: All building inspections are booked online through eTRAKiT. Building inspections are not scheduled by phone.
• Time windows: Morning requests cover 8:30 a.m. to noon, and afternoon requests 12:30 to 3:30 p.m.
• No day-of call: The inspector will not call ahead with an arrival window, so someone should be home for the full block.
• Fire inspections: If your project needs one, it goes through Santa Clara County Fire Prevention at (408) 378-4010.

What makes remodeling in Los Altos different?

• Big lots, firm height limits. According to the city's R1-10 district regulations, the zone requires lots of at least 10,000 square feet and caps homes at two stories and 27 feet. Many single-story homes have room to grow, but exterior growth means design review.
• Postwar houses. Los Altos grew quickly after World War II, so many kitchens and baths are on their second or third life. Read our guide to hidden issues in older homes before demolition.
• Orchard roots. A heritage apricot orchard still grows next to the Los Altos History Museum, so nobody here will judge you for wanting a bigger pantry.
