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.

A California contractor license is generally required when a project costs $1,000 or more in combined labor and materials, requires a building permit, or uses additional workers. Small jobs cannot be split from a larger project to qualify for the exemption. Read the CSLB requirements.
