Working with your builder

ADU schedules depend on inspections lining up. We coordinate rough and final inspections with your general contractor or work directly with owner-builders.

Questions

FAQ

Can you work from my architect's electrical plan?

Yes. We review the plan, flag anything that affects cost or code compliance, and build to the approved drawings.

Do ADUs need solar?

California's energy code requires solar on many new-construction ADUs. Requirements depend on the project type — your designer or the building department will confirm.
