Do I legally have to quote a plumbing job in California?

What documents do I need to provide to clients for plumbing jobs in California?


A licensed plumber in California is required to provide a written contract or estimate whenever he or she undertakes any plumbing project valued at at least $500.  This is in addition to the law that requires a written estimate for the entire project.

The written contract or estimate must include specific information including the following:

  1. Description of the work to be performed
  2. Total price for the work
  3. Payment schedule
  4. Information about any guarantees or warranties

If you fail to provide a written contract, quote or estimate for a plumbing job that is valued at $500 or more, you may be subject to penalties and fines by the California Contractors State License Board (CSLB). 

Providing a written contract or estimate is an important step in protecting both the contractor and the customer, as it helps to ensure that both parties understand the scope of the work and the terms of the agreement.
