Architectural Drafting & Design in Los Altos

Los Altos enforces some of the most rigorous residential design review in the Bay Area. The Design Review Commission scrutinizes second-story massing, neighborhood compatibility, mature tree preservation, and front-yard streetscape impact. Our Los Altos plans address each criterion deliberately, designed from the start to satisfy DRC review.

Tree-Sensitive Site Planning

Site plans that preserve Los Altos's protected mature trees, with TPZ (tree protection zone) compliance integrated into foundation design.

R-1-10 / R-1-15 Compliant Design

Plans tailored to Los Altos's specific R-1-10 and R-1-15 standards including FAR caps, lot coverage, and second-story area.

Architectural Drafting & Design FAQs for Los Altos

Los Altos requires Design Review Commission approval for two-story homes, additions exceeding certain thresholds, and projects in design-sensitive overlays. The DRC evaluates massing, neighborhood compatibility, and architectural quality.
Single-story additions and homes typically follow ministerial review with no DRC hearing. Many Los Altos homeowners maximize first-floor expansion before considering second stories.
Los Altos plan-check averages 8-14 weeks for single-story projects, 4-8 months for two-story DRC projects including hearings, and longer when neighbors appeal.
Yes — Los Altos has a strict heritage tree ordinance. Trees over certain trunk diameters require permits to remove and TPZ protection during construction. Our site plans address this.

★★★★★

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...
