Looking for garage conversion in Cupertino? ODL Construction is a licensed Bay Area general contractor serving Cupertino and the surrounding Silicon Valley — from Monta Vista, Rancho Rinconada, Garden Gate and beyond. Turn an underused garage into a real bedroom, office, in-law unit, or income ADU.
A garage conversion is the most cost-effective square footage you can add to a Bay Area home — the foundation, walls, and roof already exist, so you're finishing space rather than building it from scratch. It's the fastest path to an extra bedroom, a real office, or an income-producing ADU.
For Cupertino specifically, it comes down to local realities: In Cupertino, the Fremont Union school premium means additions that add bedrooms often return more than a move — but the city's R1 ordinance and second-story design review shape what's possible. Cupertino's R1 zoning includes second-story setback and privacy-protection standards plus design review for two-story projects — we design to those rules so additions clear review. We design and permit your garage conversion around exactly those conditions.
