ADU Construction in Bay Area | Lutz Custom Builders

ADU Construction

An ADU is the highest-return project most Bay Area homeowners can take on, and it is also the most paperwork. We handle the whole thing: feasibility, design, permits with your city, foundation, framing, utilities, and finish work. Detached new builds, attached units, and junior ADUs are all within scope. Because we have worked in Alameda, Santa Clara, and San Francisco counties since 1992, we know how the permitting differs between them and where projects usually stall. You get one contractor from first drawing to final inspection, transparent pricing with no surprise fees, and a unit that is legal to rent the day it is finished.
