ADUs & Home Additions in Granite Bay, CA

A second structure worthy of the property.

Granite Bay lots are large enough to build ADUs that don’t compromise the main house’s outdoor space. Half-acre and larger lots in Granite Bay have room for a properly sized detached ADU — 800-1,200 sq ft — that functions as a genuine small home for extended family, a guest cottage, or a long-term rental.

Placer County handles ADU permits for Granite Bay. The process is more involved than city jurisdictions but very manageable. We’ve submitted ADU permit packages to Placer County and know what the building department needs to see. For detached structures on large lots, we design ADUs that are architecturally consistent with the main house — materials, massing, and roofline that belong on the property rather than looking like they came from a different project.

Home additions — primary suite additions, casitas, guest wings — are also common in Granite Bay where lot size allows. We handle the complete design-build process.
