Looking for home additions 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. Room additions, primary suites, and second stories that look original to the home.
In a market where moving up costs hundreds of thousands in transaction costs and a bigger mortgage, adding on is often the smarter play — especially in top-school neighborhoods where the right addition returns more than a relocation. The key is an addition that looks like it was always there, not bolted on.
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 home additions around exactly those conditions.

Typical Bay Area ranges, not a quote. Additions price by square footage, structural complexity, and foundation work. Second stories cost more because the floor below must be reinforced. You get a fixed proposal after design.
