Right to Farm Disclosure

​Legislation effective January 1, 2009 requires that as a part of real estate transactions, land sellers and agents must disclose whether the property is located within one mile of farmland as designated on the most recent Important Farmland Map. Any of the five agricultural categories on the map qualifies for disclosure purposes, including Prime Farmland, Farmland of Statewide Importance, Unique Farmland, Farmland of Local Importance, and Grazing Land.  Detailed definitions of these categories are available. 

New counties are released each month, so please check back regularly for updates.  See the survey area map for coverage-- 96% of non-government lands are included.   

There are four ways to access the information:

  • The California Important Farmland Finder.  An interactive version of the Important Farmland map data.  Locate your area of interest, calculate acreage, and other useful features, using this online tool. Information on usage is available.
  • Geographic information system (GIS) data​.  This format expedites searching and comparison to your area of interest. The Map and Feature Services are for viewing and downloading Important Farmland data directly in ArcGIS systems.​​
  • Important Farmland Time Series: An online tool to view the Important Farmland map data as a time series, from 1984 to the present.​​​
  • Speak with one of the analysts at FMMP.  Call 916-324-0850 or email us (fmmp@conservation.ca.gov) and we will help locate your area of interest.​

Additional note regarding map categories

In some counties, components of Farmland of Local Importance are shown separately, specifically Confined Animal Agriculture facilities.  Please refer to the Cl in Local Definitions document for status of each county regarding Confined Animal Agriculture. ​

Thank you for your interest!​
