Contractor Information

Information for Home Owners


Tips to consider when selecting a contractor to work on your private sewer lateral:
  1. Use Google or the Yellow Pages to search for licensed plumbing or related contractors. 
  2. Use the District's Pre-Qualified Contractor List for the Private Sewer Lateral Program. Please note this list is provided for the convenience of our customers. The list may not include all qualified licensed contractors within Marin County and the surrounding areas. The listing of contractors on the District's Pre-Qualified Contractor List should not be assumed to be a recommendation or endorsement by the District. 
  3. ALWAYS check qualifications through the California Department of Consumer Affairs Contractors State Licensing Board. The Contractors State License Board (CSLB) protects consumers by regulating the construction industry through policies that promote the health, safety, and general welfare of the public in matters relating to construction. You should look up a contractor license or Home Improvement Salesperson (HIS) registration to verify information, including complaint disclosure. CSLB recommends you read their Hiring a Contractor page before hiring a contractor or signing a contract.
