San Jose, CA · Santa Clara County
San Jose's ADU and addition volume is among the highest in California, and the City's Building Division reviews structural submittals closely — especially lateral design in the Bay Area's seismic environment and foundation design on the valley's expansive clay soils. We deliver complete structural packages for contractors, architects and homeowners: framing plans, lateral analysis, foundation design and calculations formatted for San José's electronic plan review.

Yes. We deliver flattened, sheet-numbered PDFs with calculations as a separate bookmarked set, which matches the City's electronic submittal format.
Not always. Many single-story ADUs can be designed using code-prescribed soil values. If the site has known expansive soils or slopes, we'll flag it during scope review before quoting.
How it works
Tell us what you're building and upload whatever you already have. Plans, photos, sketches and permit comments can all be submitted.
We review the project and send you a defined engineering scope, price and estimated turnaround.
Your project moves through structural design, calculations, drafting and engineer review.
Final engineering documents are delivered through your project dashboard. Permit comments can be submitted back through the same project.
