California / Builders / Durabuilt Construction, Inc.
Licence verified, no local permit history
CSLB #968499 · DURABUILT CONSTRUCTION INC · Corporation
General contractor based in Sunnyvale. Builds garage conversions and detached ADUs, built on site. Says it serves 8 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 Most California cities do not publish the contractor's name on a building permit, so this usually reflects what a city discloses rather than what a builder has built.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.
Exempt from workers’ compensation is lawful and is not the same as suspended. A licensee with no employees may declare exemption. But if anyone is injured on your property while working on the job, exemption is the point at which a homeowner can become the employer of record. Ask who carries coverage for the crew and for every subcontractor before signing.

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.
