Home Addition Contractor in Cupertino
Stay for the schools, build the space — primary suites, second stories, and multigenerational wings designed to clear Cupertino's privacy and FAR review.
Cupertino is the South Bay's quintessential remodel-and-add market: families pay decisively to get into the school pipeline, then stay for years and grow into the home. Primary-suite additions, second stories, and multigenerational wings for parents are our staple Cupertino work.
The city's plan review is thorough and standards-driven — FAR limits enforced precisely, and second stories trigger privacy-protection measures (offset windows, screening landscape). Designing to those standards from sketch one is the difference between one review round and four.
Additions are real construction. We carry the project from feasibility through final inspection, designing for both the family's needs today and the resale value Cupertino reliably rewards.
Addition permits in Cupertino
Cupertino additions run through Community Development (10300 Torre Ave.): a building permit plus zoning review of setbacks and floor-area ratio, with second stories triggering privacy-protection measures (window placement, planting) — typically 2–3 months including review. School impact fees apply over 500 sq ft. We design to the privacy and FAR standards from the start so review clears efficiently.

Cupertino Home Additions FAQs
How much does a home addition cost in Cupertino?+
Roughly $450–$750/sq ft for ground-floor additions and $550–$850/sq ft for second stories in 2026. A 350–500 sq ft primary suite runs $200K–$360K including a full bath; multigenerational wings run $250K–$450K.
Are second-story additions hard to approve in Cupertino?+
Approvable with discipline: the city enforces FAR, daylight plane, and privacy standards (offset windows, screening landscape). Designing to those from sketch one is the difference between one review round and four.
Can I add a wing for my parents in Cupertino?+
Yes — multigenerational wings (and attached junior ADUs) are among our most common Cupertino projects. We design step-free access, full baths, and sometimes kitchenettes that convert to rentals later.
Will my property taxes go up?+
Only on the addition's assessed value — Prop 13 protects your existing basis. The increase is usually far less than the full reassessment a bigger-home purchase would trigger.
How long does a Cupertino addition take?+
Plan check 2–3 months including privacy/FAR review, then 3–6 months of construction depending on scope.
