San Jose has the Bay Area's most efficient ADU plan-check process — including pre-approved ADU designs that skip plan review entirely. Our San Jose plans take full advantage of the city's streamlined permit paths, supporting the Mayor's housing goals while delivering projects that pencil out for owner occupants and rental investors.
Pre-Approved Path Selection
Evaluation of San Jose's pre-approved ADU plan catalog versus custom design — sometimes pre-approved is the fastest path, sometimes custom delivers more value.
Custom Detached ADUs
Custom ADU plans for sites that don't fit San Jose's pre-approved templates — irregular lots, hillside conditions, or specific design goals.
Major Additions & Two-Story Pop-Ups
Additions designed within San Jose's reasonable R-1 standards, leveraging the city's less-restrictive design review than peer cities.
Custom Home Plans
Ground-up custom homes for San Jose's diverse neighborhoods — Willow Glen, Almaden, Cambrian, Rose Garden, Berryessa, Evergreen.
San Jose Drafting at the City's Speed
San Jose has made fast permits a city priority. The pre-approved ADU program, streamlined ministerial review, and supportive plan-check culture mean projects move faster here than in any peer Bay Area city. Our drafting matches that pace.

What Our Customers Say
Our clients are at the heart of everything we do at 9Builders, and their feedback reflects our dedication to quality and service. From beautiful remodels to innovative new builds, hear how we've transformed their spaces and exceeded their expectations.
Tommy, Yuna, and their entire team were amazing from start to finish. We hired them for a big project that included foundation work, a structural retrofit, replacing the PGE main service line, and installing a new 200-amp panel. It was a pretty major job, and honestly, we couldn't have asked for a better crew to handle it. Everyone was professional, polite, and knew exactly what they were doing. They showed up on time, cleaned up every day, and were super respectful of our space.
I hired 9Builders to work on my backyard and they did an amazing job. They built a nice structure that looks really great and added so much to my yard. The team was friendly and kept everything clean while they worked. The work was done quick and looked really good. Now they're working on the front of my house to add an extension, and I'm impressed how fast they worked. They finished the foundation in just two days...
9Builders transformed our kitchen into a beautiful, functional space. They listened to our ideas, offered great suggestions, and delivered high-quality work. The team was professional and respectful throughout.
