ADU Standards does not issue zoning determinations and does not endorse contractors. Licence details are from the California Contractors State License Board, checked 2026-08-15. A city that pre-approves a plan has vetted the plan, not the builder. Always confirm licence standing at cslb.ca.gov before you sign anything.
