What Does a C-34 License Cover?

Fabricates and installs pipelines for conveyance of fluids such as water, gas, or petroleum, including protective coatings and the trenching, boring, shoring, backfilling, compacting, paving, and surfacing to complete installation.

Hiring a Pipeline Contractor

Pipeline work may require encroachment permits for work in public rights-of-way. Verify the contractor carries adequate insurance for underground utility work and ask about their locate and mark procedures to avoid existing utility conflicts.

California law requires a contractor license for this type of work on projects valued at $500 or more (combined labor and materials). Hiring an unlicensed contractor for work requiring a license may void your consumer protections.
