Plumbing Apprenticeships in California

63 registered apprenticeship programs in California train plumbing apprentices. Registered apprenticeships (U.S. Dept of Labor) pay wages from day one — training costs are typically covered by the sponsor instead of tuition. Most run 2–5 years to full journey-level pay, and you apply directly to the sponsor. Licensing note: completing an apprenticeship program is accepted as journey-level qualification, and apprenticeship time earns experience credit toward the 4-year requirement.

Sponsor data: U.S. Dept of Labor Registered Apprenticeship (apprenticeship.gov), refreshed quarterly; locations reflect DOL registration records. Duplicate registrations and corrections-facility programs are filtered from display. Independent site — not affiliated with the U.S. DOL. About half of states run their own apprenticeship agencies (incl. NY, MN, OR, VT, WA, DC) — federal data undercounts those states, so a low count there does not mean apprenticeships don't exist.
