Williamson Development Group

Williamson Development Group operates out of Lake Elsinore in Riverside County and carries CSLB license #990201, classification A — General Engineering, B General Building, C10 Electrical. The license was active and clear when this listing was compiled.

A C-10 electrical license covers the wiring, panels, circuits and fixed equipment that distribute electrical power through a building.

Working in southwest Riverside County: This corridor has grown fast, 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 electrical contractor: If you are adding an EV charger, ask for a load calculation on the existing panel before anyone quotes the circuit.

License status can change at any time. Confirm license #990201 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
