This ADU build on Montclair Dr in Santa Clara, CA showcases 9Builders’ end-to-end expertise in delivering compliant, high-quality accessory dwelling units in the heart of Silicon Valley. From early site evaluation and city permitting through foundation work, framing, and interior finishes, our team handled every phase of construction with precision and care.
Santa Clara has embraced ADU-friendly zoning that lets homeowners add valuable square footage — and meaningful rental income — without the cost and disruption of a full home addition. On the Montclair Dr property, we coordinated closely with city planners, structural engineers, and CHEERS-registered Title 24 documentation authors to make sure the new unit met every code requirement while staying on budget and on schedule.
The build included a poured concrete foundation engineered for Bay Area soil and seismic conditions, structural framing aligned with current California Residential Code standards, and modern, low-maintenance interior finishes selected for long-term durability. Whether the goal is multigenerational living, a private home office, or a rental unit to offset Silicon Valley housing costs, the Montclair Dr project illustrates the kind of turnkey ADU construction 9Builders delivers across Santa Clara, Cupertino, Sunnyvale, and the wider Bay Area.
