Belmont's steep terrain demands drafting that understands hillside engineering. Our plans handle Belmont's grading ordinance, retaining wall design, drainage, and view-corridor preservation while satisfying San Mateo County Building Inspection. From hilltop ADUs to view-side additions, we design for sites that flat-lot drafters get wrong.

Hillside Home Plans
Custom and addition plans for Belmont's sloped lots with stepped foundations, terraced grading, and retaining walls integrated into structural drawings.
View-Preserving ADUs
ADU placement designed to preserve primary residence views and meet Belmont's daylight plane and setback requirements.
Drainage & Grading Plans
Civil drainage design coordinated with structural foundation work — required for any Belmont permit involving more than 50 cubic yards of grading.
Foundation Engineering Coordination
Pier-and-grade-beam, drilled cassions, and retaining-wall systems designed with our partner geotechnical and structural engineers.
Belmont Plans That Respect the Hill
A poorly drafted hillside plan creates expensive surprises in construction — exposed foundations, drainage failures, and retaining wall blow-outs. Our Belmont drawings integrate site, structure, and drainage from day one so the build matches the plan.

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.
