Building in Los Altos
Custom Home Builder in Los Altos, CA
Los Altos is one of the more demanding places to build in the Bay Area, and that's by design — the city protects its neighborhood character closely, from architectural review down to individual trees on a lot.

Start a conversationDesign review
Nearly every project that changes a home's exterior, adds square footage, or alters the roofline in Los Altos' single-family (R1) district goes through the city's design review process, guided by its Residential Design Guidelines and a required Neighborhood Compatibility Worksheet that looks at properties within 300 feet of the site. For a teardown-rebuild, that review starts well before a shovel goes in the ground.
The tree ordinance
Los Altos' Tree Protection Ordinance protects any tree with a trunk 12 inches or more in diameter — 10 inches for native oaks and California buckeyes — a threshold the city lowered from 15 inches in 2024, meaning more trees on a typical lot now require a permit before removal. Removing a protected tree without one can mean a fine of $5,000 or more. On a teardown-rebuild especially, mapping which trees on the lot are protected is one of the first steps, not an afterthought.
Building here
We've built and remodeled across Los Altos — from a two-story custom home on a wide motor court to living room and rear additions on existing homes — and in each case, design review and tree permitting shaped the schedule as much as construction itself.
What to Expect
Most Los Altos lots run large enough for a meaningful teardown-rebuild or whole-home remodel, though mature trees and strict design review often narrow the buildable footprint more than the zoning code alone suggests. Staff-level design review typically adds 2 to 4 weeks to the schedule; projects that need full Planning Commission review — common on a teardown-rebuild — can add 2 to 4 months on top of that.
Vidsan Builders' custom home and whole-home remodel services both run through this same process in Los Altos.

Frequently Asked Questions
How long does design review take in Los Altos?
Staff-level review typically adds 2 to 4 weeks to the schedule. Projects that need full Planning Commission review — common on a teardown-rebuild — can add 2 to 4 months on top of that.
Do I need to survey trees before applying?
Yes. With the protected-tree threshold at 12 inches in trunk diameter (10 inches for native oaks and California buckeyes), mapping which trees on the lot are protected is one of the first planning steps, not something to sort out after submitting.
