Garage conversions built around how San Jose actually permits second units

San Jose is big enough that there's no single 'San Jose garage' — a detached two-car garage on a 1960s Willow Glen bungalow lot is a different project than a deep three-car garage on a newer Evergreen tract home. San Jose's planning and building departments run an active, high-volume permit process for ADUs and JADUs, and the city has published standards most homeowners can check against before they call a contractor. That's good news, but it also means reviewers see a lot of submittals and flag drawings quickly when they don't match the checklist. We start every San Jose project by confirming your specific garage's structure, your lot's zoning, and whether a JADU or full ADU actually fits your goals, rather than assuming your project will move like the last one we did across town.

Por Qué los Propietarios de San Jose Nos Eligen

San Jose homeowners come to us because the city processes a high volume of ADU and JADU permits, and a submittal that isn't drawn to the current checklist gets bounced back into that queue instead of through it.

JADU & ADU permitting specialists

We know the difference between a JADU and an ADU cold, and scope your project to the one that actually fits your goals.

Licensed, bonded & insured

Full California contractor's license and insurance coverage — ask to see it.

We know San Jose's specific rules

San Jose reviews a high volume of ADU and JADU submittals — we draw against the current checklist so your project doesn't get sent back into that queue for an avoidable correction.

We evaluate what's already there

Existing garage slabs, framing and rooflines aren't automatically reused or automatically torn out — we assess what's structurally sound first.

Preguntas Frecuentes

Preguntas que nos hacen los propietarios

Generally no — California's state ADU and JADU law significantly limits what local ordinances can restrict, including outright bans in most residential zones. San Jose can still apply setback, height and design-review rules, which we confirm against your specific address.

A JADU stays within your garage's existing footprint, is capped at 500 square feet, and can share utilities with the main house — usually a simpler, faster permit. An ADU can be larger or detached, requires independent utilities, and has no owner-occupancy requirement.

It depends on project type and how busy the city's plan check queue is when you submit — a JADU with shared utilities typically moves faster than a detached ADU with new utility connections. We'll give you a realistic timeline once we've reviewed your specific garage and plans.

Yes — we prepare the Title 24 energy calculations and CF1R documentation as part of every permit package, and manage plan check correspondence directly with the city so you're not the one interpreting correction letters.
