Every Bay Area city plays by different rules. Palo Alto requires Architectural Review Board approval, Cupertino enforces strict R-1 standards, San Jose offers streamlined ADU plan-check, and Saratoga has a Hillside Specific Plan. We draft plans across all of them — month after month — so we know what each reviewer expects and where projects get stuck.
ADU Plans for Every Jurisdiction
ADU plans tailored to each city's ordinance — San Jose pre-approved program, Sunnyvale's ADU-friendly path, Cupertino's strict design overlay.
Multi-Story Additions
First-floor additions, second-story pop-ups, and primary suite expansions designed for each city's setback, height, and design rules.
Custom Home Design
Ground-up homes from infill lots in Mountain View to estate parcels in Atherton, drafted with the structural and Title 24 documentation each city requires.
Permit-Ready Submittal Sets
Complete construction documents formatted to each Bay Area city's plan-check portal — no rejected submittals over formatting.
Bay Area's Most Versatile Drafting Team
Plan-check rejections are expensive. Each Bay Area city has its own preferred drawing standards, redline conventions, and reviewer expectations. We submit to all of them constantly — Palo Alto, Cupertino, Mountain View, Sunnyvale, San Jose, Saratoga, Los Gatos — so your plans land right the first time.

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.
