There are various water providers throughout the area and water restrictions may vary among providers. The City’s water conservation ordinance applies to everyone within the incorporated City of Thousand Oaks regardless of your service provider. In cases where the restrictions of your service provider do not align with the City’s requirements, you will need to follow the more stringent (stricter) requirements. Residents living in the unincorporated area of the City must abide by the restrictions of your water service provider. If the City is your water service provider you will follow the same Level 3 restrictions as the incorporated area. Verify your water provider by locating your most recent bill, contacting your landlord, or look up your address below.

To use the address look-up, you can search by address and then click to the side of your home to see who your local water provider is. Additionally, you can scroll and zoom to your general area and click on the pink to identify the agency. This tool is provided by the California State Water Board.
