ADU Construction in Cupertino — What We Do
California's ADU laws have transformed Bay Area properties into multi-unit assets. We design and build ADUs that comply with state ADU statutes and each city's local ordinances — from Palo Alto to San Jose to San Francisco — so the project moves fast and the finished unit holds long-term value.
Cupertino homeowners have hired us for adu construction projects across the city. As a fully licensed California general contractor (CSLB #1008964) with 11 years of Bay Area experience, we know exactly what Cupertino permitting, construction conditions, and homeowner expectations look like.
Cupertino Permits & Process
Cupertino's Community Development Department reviews remodels with attention to accuracy and completeness — incomplete submittals get returned. We submit fully-engineered packages so the project moves to issuance without back-and-forth.
