The Only Pre-Approved Garage Conversion Builder in San Jose
The City of San José publishes a list of pre-approved ADU vendors. SYMBiHOM is the only one on that list approved specifically for garage conversions — attached and detached, studio through 2-bedroom. Every other vendor on the list builds new detached units on foundations. We convert the garage you already have.

What That Means for Your Permit Pre-approval means the City has already reviewed our plans. When you submit, you're not waiting for a plan check from scratch — you're submitting a site-specific packet against plans the City already accepted. Same-day permit issuance is possible when the site-specific plan and related documents are accurate and complete.
We handle the permit process. You don't pull permits yourself.
