Hiring a Well Drilling Contractor

Well drilling requires permits from the local enforcing agency and must comply with state well standards. Verify the contractor is familiar with local groundwater conditions and permitting requirements. Ask about well yield testing and water quality testing after completion.

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.
