Los Altos Zoning, Planning & Building Codes
What you can build in Los Altos depends on its local zoning and planning code, layered on the California Building Standards Code. Ask GoCodebook about any Los Altos address.
Key points
Los Altos is a city in Santa Clara County, California. Like every California jurisdiction, Los Altos regulates development through a local zoning and planning code (often Title 14) — the rules that determine allowed uses, setbacks, height limits, FAR, density and parking — on top of the statewide California Building Standards Code (Title 24).
Those local rules change at the city line, so a remodel, ADU or use that is allowed nearby may be restricted in Los Altos. GoCodebook reads the Los Altos ordinance with state code and answers your zoning, planning or permit question with the controlling citation.
Zoning & planning in Los Altos
Los Altos's zoning code (often Title 14) assigns each parcel to a district (residential, commercial, industrial, mixed-use and overlays) that sets the allowed uses, setbacks, height, FAR, lot coverage and density. Conditional uses, variances and design review may require discretionary planning approval.
Ask GoCodebook "what's the zoning for [address] in Los Altos?", "what setback / FAR applies?", or "can I build an ADU or addition here?" and get a cited answer. See coverage.
Building permits & remodeling in Los Altos
Construction and remodeling in Los Altos must comply with the adopted Building, Residential, Electrical, Plumbing, Energy and Fire codes, plus any Los Altos local amendments — and most work needs a building permit.
Additions, remodels and change-of-use can trigger extra requirements (accessibility, energy upgrades, fire). GoCodebook flags what applies to your Los Altos project before you apply.
Where to read the Los Altos code
The Los Altos municipal and zoning code is published on American Legal Publishing — view the official Los Altos code library. That lets you read the ordinance section by section.
GoCodebook goes beyond browsing American Legal Publishing (see how they compare): it reads the Los Altos ordinance together with the California Building Standards Code and answers your question — zoning, setbacks, FAR, height, ADUs, permits — with the controlling citation for your parcel.
ADUs, housing & tenant rules in Los Altos
California's statewide ADU laws override many local restrictions, so Los Altos must allow accessory dwelling units that meet state size, setback and parking standards. Rentals may also be subject to rent control and AB 1482 protections.
Whether a specific Los Altos property is covered depends on its zoning, age and ownership — exactly the kind of question GoCodebook answers with a citation.
