What is a Williamson Act Contract? A Williamson Act Contract is the legal document that obligates the property owner, and any successors of interest, to the contract's enforceable restrictions.
The Act creates an arrangement whereby private landowners contract with counties and cities to voluntarily restrict their land to agricultural and compatible open-space uses.
A landowner must submit an application to the City or County requesting the contract be cancelled for a portion or the entirety of the contracted area. See the Contract Cancellations page for detailed information and constraints. For questions regarding cancellations, contact your local Planning Department.
