R B Development is a licensed California contractor based in Big Bear City, San Bernardino County, holding CSLB license #449906 under classification A — General Engineering, B General Building, C10 Electrical. License status at the time of compiling this listing: active, with no suspension recorded.
Electrical contractors carry the C-10 classification, which covers everything from a single circuit to a full service upgrade and the permits that go with it.
Working in the local mountain communities: Mountain properties carry snow load, freeze-thaw cycles and steep or seasonal access — all three change how a job is specified and priced.
Before you hire any electrical contractor: Ask about permits and inspection explicitly. Electrical work is inspected for a reason, and unpermitted panel work is a common problem found during a home sale.
License status can change at any time. Confirm license #449906 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
