Quick answers about building an ADU in the Bay Area with SFBayADU.

SFBayADU is a one-stop ADU builder in the San Francisco Bay Area. We handle the whole project: design, permits and engineering, general construction, interior design and cabinetry, and landscape design. We have over 15 years of ADU experience.
What types of ADUs do you build?
We specialize in backyard homes from 600 to 1,200 sq ft: studios, 1-bedroom/1-bath, 2-bedroom/2-bath, and 750, 1,000 and 1,200 sq ft plans. We also build garage conversions, garden cottages, granny flats, secondary dwelling units and mother-in-law suites.
Which areas do you serve?
Our main focus is the Bay Area. We are based in San Jose, and we have built ADUs in San Jose, Palo Alto, Sunnyvale, Los Altos, Los Altos Hills, San Mateo, San Carlos, Foster City and other cities.
What are pre-approved ADU plans, and do you have any?
Pre-approved plans are standard designs the city has already reviewed, which makes permitting faster and more cost-effective. Several SFBayADU plans are pre-approved by the San Jose Building and Planning Department, and our 747 sq ft, 2-bedroom, 1-bath design is approved under the City of Milpitas Pre-Approved ADU Program (2026). A site-specific submittal is still required for your parcel, and our team handles that step for you.
How long does it take to build an ADU?
Our builds typically take about eight to twelve months from signing the Project Services Agreement to final inspection. The exact time depends on your design, zoning, your lot, and whether the ADU is two-story. Some of our models use off-site panelized framing, which reduces on-site work and weather delays.
Do you handle the permits?
Yes. Our team handles permits, engineering, surveys and city coordination for you, and works with the city through every inspection.
How much will my ADU cost?
Cost depends on the size, design and site. A 750 sq ft ADU is a good option if you are watching the budget because it helps minimize impact fees. For a ballpark number, request a free instant quote: it takes a few minutes, has no commitment, and gives you a feasibility overview and a basic cost estimate.
