Reports and Statistics


Data and Maps

A Williamson Act contract is entered into by the landowner and the participating city or county. Current enrollment and contract information is held by the city or county offering the contract. For the most current and up to date information on the status of Williamson Act contracted parcels the Department suggests that interested parties contact the ​city or county in which the property resides.

California Williamson Act Enrollment Finder

T​he recent passage of Senate Bill 574 has simplified Williamson Act reporting requirements. Enrollment information is now collected in Geographic Information System form, and is made available through the California Williamson Act Enrollment Finder.​

Biennial Williamson Act Status Reports

Until the recent passage of Senate Bill 574​, Williamson Act Status Reports were mandated by Government Code section 51207. The reports provided information to the Legislature and general public on the implementation of the Act by counties and cities. Except for the first two reports, the reports were produced in even numbered years and contain detailed enrollment statistics for the previous two years.

Although Senate Bill 574 has eliminated the biennial Williamson Act Status Report, prior reports are available below or can be obtained by contacting the Department via email at:
