Good to Know
Common Questions Before You Call
These are the questions homeowners most frequently ask before reaching out.
We focus on permitted, large-scale construction — ADU builds, detached backyard units, garage conversions, custom homes, room additions, and full-scope renovations. If your project requires permits, engineering review, and a coordinated construction team, it’s worth a conversation.
No. Most homeowners contact us before any plans exist. The first call is about project type, rough scope, and timeline. If there’s a fit, we’ll schedule a site visit and discuss next steps from there.
That depends on permit timelines with the City of Lafayette or the relevant jurisdiction, site conditions, and current scheduling. ADU projects in Lafayette typically move through the permit process faster than they did before 2020, but design and permitting still run several months before groundbreaking.
Yes. Our active service area covers Lafayette, Orinda, Walnut Creek, Pleasant Hill, Danville, San Ramon, Oakland, and the broader East Bay. Homeowners in Contra Costa and Alameda counties are welcome to reach out and we’ll confirm coverage during the first call.
