ADU Design & Permitting in San Jose
Our design process starts with a site survey and a review of your lot's setbacks, easements, and utility access, then moves into schematic design and construction documents sized to your budget and goals. Where your project fits San Jose's pre-approved ADU plans program, we can significantly speed up the review timeline by using a plan set the city has already vetted.
Permitting fees for an ADU in San Jose are typically $1,000–$5,000 depending on project scope, and most compliant ADUs qualify for ministerial (staff-level) review — around 60 days — rather than a discretionary hearing. We prepare and submit the full plan set, respond to plan-check comments, and track the permit through to issuance.
Design-and-permitting-only engagements are available for homeowners who have their own builder, as well as full design-build packages that carry the project through construction. Text us for a free consultation to discuss your project.
What is San Jose's pre-approved ADU plans program?
It's a program offering plan sets the City of San Jose has already reviewed and approved, which can significantly shorten the permitting timeline compared to a fully custom design. We'll confirm whether your lot and goals fit one of the pre-approved plans during a free consultation.
