Bonanza Plumbing is a licensed California contractor based in Loma Linda, San Bernardino County, holding CSLB license #752111 under classification B — General Building, C36 Plumbing. The license was active and clear when this listing was compiled.
Plumbing contractors hold the C-36 classification, covering repipes, drain and sewer work, gas piping and water heater installation.
Working in the Inland Empire: The region sits between the San Andreas and San Jacinto fault systems, so seismic requirements are woven through the building code here in ways they are not everywhere.
Before you hire any plumbing contractor: On a water heater replacement, confirm seismic strapping, the expansion tank and the venting are all included. Those are code requirements, not upsells.
License status can change at any time. Confirm license #752111 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
