How to Become a Plumber in California
Plumbers in California install and maintain water, drainage, gas, and related piping systems across residential, commercial, industrial, and public infrastructure projects. The statewide median wage for plumbers, pipefitters, and steamfitters is $68,390 per year, and employment is projected to grow by 8% from 2022 to 2032.
Most California plumbers learn through union, employer, or contractor-sponsored apprenticeship programs that combine paid on-the-job training with classroom instruction. A plumbing apprenticeship commonly lasts about five years.

Note: Training pathways vary by employer, program sponsor, and licensing category. Classroom education may provide useful technical preparation, but it does not automatically replace supervised work experience unless the applicable licensing authority specifically allows that credit.
