About Acton ADU
Acton ADU is a Bay Area-based design-build firm with over 35 years of construction experience, specializing exclusively in accessory dwelling units. Founded by Stanley Acton and headquartered in Campbell, CA, the company handles every phase in-house: feasibility assessment, custom design, permitting, construction, and warranty. All units are site-built to California residential standards — not prefab or modular. In San Jose specifically, Acton ADU holds the distinction of having the most pre-approved ADU floor plans on file with the city, significantly reducing permitting timelines for homeowners. Their Build Ready series offers standardized floor plans with predictable costs, while the Signature Series caters to homeowners who want elevated finishes and premium design. Their process is fully turn-key — they manage permit navigation across 40+ Bay Area jurisdictions, offer designer-curated interior packages, and provide financing guidance. Bay Area detached ADU costs typically run $225K–$475K depending on size, with a total project timeline of 9–14 months including permitting. They serve 40+ cities across the South Bay, Peninsula, and East Bay. Customers consistently praise the company for transparent communication, professional project management, and their expertise navigating San Jose's permitting process. Best suited for San Jose homeowners seeking a completely hands-off ADU build with pre-approved city plans.
