Los Altos Contractor — Remodels, ADUs & Real Estate
Design-build construction, ADUs, permits, real estate, and financing in Los Altos — from our Sunnyvale headquarters, minutes away.
Los Altos is quiet money: rancher-era homes on quarter-acre lots, a walkable village downtown, and one of America's wealthiest zip codes choosing understatement over display. Construction here means matching that sensibility — generous single-story remodels, indoor-outdoor living, guest houses rather than 'ADUs' — executed to standards that hold up under sophisticated owners.
The lot sizes change the playbook: where Sunnyvale squeezes a 600 sq ft ADU behind a ranch, Los Altos hosts 1,000–1,200 sq ft guest houses with proper setbacks to spare. Additions stretch without crowding. And in Los Altos Hills, septic, slope, and fire-zone factors make experienced site assessment essential before promises get made.
Permits in Los Altos
Los Altos Building Division (1 N. San Antonio Rd.) reviews kitchens/baths in 3–7 weeks; additions 2–3 months with design review on larger scopes. Los Altos Hills (separate town) adds site-development review for slope/septic/fire factors. ADUs in both ride the 60-day state clock.

Los Altos FAQs
What does a Los Altos whole-home remodel cost?+
Premium tier: $350–$600/sq ft for down-to-studs remodels, kitchens $100K–$250K, additions $500–$800/sq ft. Larger lots keep site logistics easier than Palo Alto, but finish expectations are equivalent.
Can I build a large guest house in Los Altos?+
Usually yes — state ADU law guarantees the baseline, and Los Altos' lot sizes comfortably host 1,000–1,200 sq ft detached units (the practical ceiling under most local standards). We design them as true guest houses: full kitchens, vaulted ceilings, private orientation.
Do you build in Los Altos Hills too?+
Yes, with the added discipline Hills parcels demand: slope analysis, septic capacity, fire-hardening (much of the town is WUI fire zone), and the town's site-development process. Our feasibility work answers those questions before design money is spent.
We're keeping the house single-story — can we still gain space?+
Los Altos is the best city in the county for it: lot coverage allows generous ground-floor additions, and the market actually prefers expansive single-story living. Wing additions, great-room expansions, and connected guest suites are our standard Los Altos work.
