CSLB #1034500 · AS LEVEL UP HOME BUILDERS · Corporation
Design-build ADU contractor based in Mountain View. Builds detached ADUs and attached ADUs, built on site. Says it serves 25 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 Most California cities do not publish the contractor's name on a building permit, so this usually reflects what a city discloses rather than what a builder has built.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.

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.
