Garage Conversions
Turn your garage into a fully permitted ADU
A garage conversion is often the fastest and most cost-effective way to add an ADU in San Jose — the foundation, walls, and roof are already in place, which keeps costs down and shortens the construction timeline.
Our design-build team handles the entire garage-to-ADU conversion: space planning, structural upgrades, plumbing and electrical, city permits, and construction through final inspection — a fully permitted living space ready to serve as a rental unit, guest house, or home office.
FAQs
ADU questions, answered
Most of our custom site-built ADUs fall between $250,000 and $450,000 depending on size, site conditions, and the finishes you choose. Garage conversions typically cost less because the foundation and structure already exist. Every project gets a detailed line-item estimate before construction begins.
Plan on two phases: design and permitting typically take 3 to 5 months depending on your city's review times, and construction usually adds another 6 to 9 months. We give you a project-specific schedule during the design phase and keep you updated at every milestone.
Yes. As a design-build contractor, we manage the full approval process — architectural plans, structural engineering, permit submittals, and city inspections — so you have one accountable team from first sketch to final sign-off.
A garage conversion is usually the fastest and most budget-friendly route because it reuses your existing foundation, walls, and roof. A detached ADU costs more but offers more flexibility in size, layout, and privacy. We walk you through both options during your free consultation.
No — every ADU we build is custom-designed and built on site for your specific property. Site-built construction gives you full control over layout, materials, and finishes, and lets the new unit blend seamlessly with your existing home — flexibility that factory-built prefab units don't offer.
