Sunnyvale Contractor — Remodels, ADUs & Real Estate
Design-build construction, ADUs, permits, real estate, and financing in Sunnyvale — from our Sunnyvale headquarters, minutes away.
Sunnyvale is where BARC lives — our crews can be anywhere in the city in minutes. The housing stock is classic Silicon Valley: 1950s–70s ranches (including genuine Eichlers in some tracts), on generous lots, owned increasingly by tech families who want modern open interiors and income-producing ADUs.
Sunnyvale runs a famously organized One-Stop Permit Center, but the city has particulars worth knowing: single-story combining districts that constrain second-story additions in certain neighborhoods, Eichler-specific design considerations, and active plan-check review on energy compliance. We navigate all three weekly.
Permits in Sunnyvale
Sunnyvale's One-Stop Permit Center (456 W. Olive Ave.) handles building permits with online submittal. Typical 2026 timelines: over-the-counter for minor scopes; 3–6 weeks kitchens/baths; 2–3 months additions (longer where single-story district review applies); ADUs within the 60-day state clock.

Sunnyvale FAQs
Are you really based in Sunnyvale?+
Yes — BARC is based in Sunnyvale. Sunnyvale projects get the practical benefits of a hometown contractor: fast site visits, crews minutes away, and constant working contact with the One-Stop Permit Center.
Can I add a second story in Sunnyvale?+
Depends on your tract: parts of Sunnyvale sit in single-story combining districts where second stories face added restrictions or aren't allowed. We check your parcel's zoning in the first consultation and, where second stories are restricted, design ground-floor additions or ADUs that hit the same goals.
Do you work on Eichler homes?+
Yes, carefully — radiant slabs, post-and-beam structure, and atrium glazing demand Eichler-literate design and trades. We remodel them in ways that modernize systems without destroying the architecture (or the resale premium it carries).
What does an ADU cost in Sunnyvale?+
Same Santa Clara County math: $125K–$220K for garage conversions, $220K–$330K for detached studios/1BRs, $320K–$480K for 2BR units, all-in. Sunnyvale rents support $2,600–$4,200/month depending on size — among the Bay Area's best ADU rent markets.
