San Jose Garage Conversions exists to turn underused garages into JADUs, ADUs, home offices, in-law suites and detached backyard units — permitted, Title 24 compliant, and built around the structure you already have. We don't take on ground-up new construction or unrelated remodels; every job we run is a conversion of an existing garage.
Garage conversions live at the intersection of two things a lot of general contractors underestimate: an existing structure that has to be evaluated, not assumed, and a permit path — JADU or ADU — that changes the entire scope depending on which one you're building. Our crew works exclusively in that intersection across San Jose and the wider South Bay and Peninsula, which means we've evaluated garage slabs, framing and rooflines for reuse far more often than a contractor who occasionally adds a garage job to a broader remodeling business.
We're licensed, bonded and insured, and we handle the Title 24 energy compliance and permit package in-house rather than treating it as a separate step you have to manage yourself. When a city's setback rule, second-unit ordinance or egress requirement changes what's actually buildable on your lot, we flag it during design — before you've committed to a floor plan that plan check will send back.
We assess your garage's existing slab, framing, ceiling height and utility access before drawing a floor plan, so the design fits what's actually there instead of what a generic template assumes.
Permit packages, Title 24 energy calculations and plan check coordination are part of our scope, not a separate consultant you have to hire and manage yourself.
Because the permit path and utility requirements differ significantly between a JADU and an ADU, we help you decide which one fits your goals and your lot before any drawings start.
Tell us what you're converting it into — a JADU, an ADU, an office — and we'll get back to you with next steps, usually within one business day.
