Chien Hung Yuan

Chien Hung Yuan is a licensed California contractor based in Chino, San Bernardino County, holding CSLB license #826710 under classification B — General Building, C10 Electrical, C16 Fire Protection, C36 Plumbing. The license was active and clear when this listing was compiled.

The C-36 classification covers complete plumbing systems — supply lines, drains and vents, gas lines, water heaters and fixtures.

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: For a repipe, ask what material is being used and how many walls have to be opened — and who is responsible for patching them afterwards.

License status can change at any time. Confirm license #826710 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
