Accessory dwelling unit construction across San Francisco: detached, attached, and garage conversions. We handle drawings, SF Planning approval, DBI permits, and the full build. Built to maximize rental potential and pass inspection the first time.
An ADU is the single highest-value thing most San Francisco homeowners can add to their property, but only if it's done well. A cheaply built ADU is a tenant problem waiting to happen. A well-built one rents at market rate for decades.
We've built detached ADUs, attached additions, and garage conversions across San Francisco. Each one is sized for the specific lot, designed for actual rental appeal, and built to a standard that holds its value.
Walk the lot, identify what type of ADU makes the most sense, detached, attached, or garage conversion, given your zoning, setbacks, and goals.
Coordinate the architectural and structural drawings, plus SF Planning approval. ADU rules in SF are favorable but specific.
Full DBI permit handling for foundation, framing, plumbing, electrical, and mechanical.
New foundation for detached units, structural integration for attached additions, conversion framing for garage ADUs.
Separate or shared utilities depending on your plan. Electrical service, plumbing, and HVAC sized for the unit.
Interior finish to a standard that rents well. Kitchen, bath, flooring, paint, fixtures.
Most ADU work in San Francisco starts with feasibility: lot size, setbacks, parking impact, and what SF Planning will allow. Drawings come next, then DBI permits, then the build. Detached, attached, and garage-conversion ADUs all follow this same path. Timelines depend on scope and which permits the lot triggers.
