Based in Hemet, Riverside County, Biddle David William holds California contractor license #612720, classified B (General Building). The license was active and clear when this listing was compiled.
A general contractor’s work is coordination as much as construction: framing, roofing, electrical, plumbing, drywall, finish carpentry and inspection sign-off all have to happen in sequence, and the general is the one holding that sequence together. Typical jobs run from a single-room addition to a full structural remodel.
Working in southwest Riverside County: This corridor grew quickly, so the housing stock ranges from 1970s tract homes to work finished last year — and the two need very different approaches.
Before you hire any general contractor: Ask which parts of the job are being subcontracted and to whom. A general is entitled to subcontract, but you are entitled to know whether the electrician on your addition is licensed, and to get conditional lien releases as each sub is paid.
License status can change at any time. Confirm license #612720 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
