ADU Design in Cupertino, CA
The heart of Silicon Valley and home to Apple Park, Cupertino is a high-value tech-campus city where Class-A office, R&D, and data-heavy facilities dominate. Some of California's highest construction costs meet extreme seismic exposure (Monte Vista–Shannon and San Andreas faults), dense infill constraints, and a foothill edge with hillside and fire considerations.
