Lafayette General Contractor & Custom Home Builder Across the San Francisco Bay Area
A Lafayette-based general contractor with 37 years of experience — building since 1989. We design and build custom homes, ADUs, additions, and full remodels across the East Bay, Contra Costa, Alameda, San Francisco, and the Peninsula, with one licensed team from first consult to final sign-off.
What Rhino Builders Does — And Where
Rhino Builders is a licensed general contractor and custom home builder based in Lafayette, serving the entire San Francisco Bay Area — ADU construction, custom homes, additions, and major renovations from the East Bay and Contra Costa to Alameda, San Francisco, and the Peninsula.
An Accessory Dwelling Unit — a self-contained secondary residence added to your property — is one of our core builds. We also build JADUs, garage conversions, room additions, ground-up custom homes, and full structural renovations.

Hear It From the Homeowners
Built Around Bay Area Permit Processes
Every Bay Area city and county runs its own building department, and we work inside them every week — from Contra Costa and Alameda to San Francisco, including the jurisdiction-specific overlays that cities like Lafayette, Orinda, and Walnut Creek layer on top of state law.
Incorporated cities often interpret Title 24, setbacks, and plan-check timelines differently than unincorporated county land. Knowing that difference before you submit saves weeks.
We know which documentation triggers a correction letter and which plan set moves straight through — because we do this work here, not from a template.
Talk Through Your Permit
One team eliminates the coordination gap
Fragmented projects stall at handoffs — the architect passes off drawings, the expediter waits, the GC mobilizes only after a permit issues. A correction letter lands and nobody's sure whose job it is to respond.
At Rhino Builders, the same team that draws the plans submits them, answers the corrections, and builds the project. Design through final inspection, under one roof — which is what makes our timelines predictable.
A clear path from first call to final sign-off
