California Licensing (CSLB)
California licenses plumbing contractors through the Contractors State License Board (CSLB) — the C-36 Plumbing license. Journeyman status is not separately licensed at the state level, but many contractors require documented UA apprenticeship completion or equivalent experience. Apprentices must register with the California Department of Industrial Relations.

UA Local Coverage
Three UA locals cover the Bay Area: Local 467 (Santa Clara County, South Bay), Local 393 (San Jose, HVAC cooling overlap), and Local 342 (Alameda, Contra Costa, Marin, Napa, Solano). All run Joint Apprenticeship Training Committees with 5-year paid programs. We route you to the local whose jurisdiction covers your ZIP code.

Pay Scale
UA Local 467 journeyman inside wireman scale runs approximately $58–65/hr + full benefits (health, pension, annuity). Apprentices start at 45–55% of journeyman scale and receive 5% step increases approximately every 6 months. At journeyman scale with overtime, total compensation commonly reaches $115k+.

Demand Drivers
The Bay Area's housing shortage is being addressed through dense mid-rise and high-rise residential construction — all of which requires extensive rough-in and finish plumbing. Data center buildouts, hospital and biotech lab expansions, and deferred infrastructure repairs are driving sustained demand for licensed journeymen through 2030.

OSHA 10 Requirement
Most Bay Area commercial general contractors require OSHA 10 certification before a first day on site. Factor in ~$150 and 2 days of online training if you don't have it. High-rise and industrial sites often require OSHA 30. We flag requirements in your qualification results.
