CSLB #1108833 · ASHER BROTHERS CONSRTUCTION INC · Corporation
Design-build ADU contractor based in Danville. Builds attached ADUs, garage conversions and detached ADUs. Says it serves 14 California cities.
No ADU permits are on file under this licence in the cities we cover. Most California cities do not publish the contractor's name on a building permit, so this usually reflects what a city discloses rather than what a builder has built. Ask them directly for recent addresses and permit numbers you can look up.

The company’s own description · licence shown on their advertising matches the state register
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.
