408 Builders Inc completely transformed Mrs. Biranchi's San Jose garage from a cluttered, unfinished space with exposed rafters and bare concrete into a clean, functional, and polished area. The original garage featured an open ceiling, no insulation, old concrete flooring, and dated doors throughout. The renovation included full ceiling framing, insulation, a nd drywall, a new insulated garage door, new entry door and window, full interior paint, and a professional epoxy floor coating — resulting in a bright, well - finished garage the whole family can enjoy.

-
How much does an ADU cost in San Jose?ADU construction in the Bay Area typically ranges from $150,000 to $350,000+ depending on size, type, and finish level. Garage conversions tend to be on the lower end, while new detached units cost more.

Will 408 Builders handle the permits for my ADU?Yes. We handle all permit applications, plan submissions, and city inspections on your behalf. We're experienced with San Jose's ADU ordinance and keep your project compliant from start to finish.
