Conrad Robert Warren operates out of Calimesa in Riverside County and carries CSLB license #867406, classification C10 — Electrical. At the time this listing was compiled, the license was active with no suspension on record.
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 San Gorgonio Pass: Growth here has been fast, so the housing stock runs from older ranch properties to tracts finished in the last few years, and the two need different approaches.
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 #867406 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
