California Land Conservation Act

The California Land Conservation Act, also known as the Williamson Act, is a law that encourages farmers and landowners to keep their land in agricultural or open space use by offering them property tax incentives. Instead of paying higher taxes based on the land’s market value, participants agree to a long-term contract with local governments that limits development. This helps preserve farmland, natural landscapes, and open space, supporting agriculture and environmental conservation while maintaining local planning flexibility. The act balances land use preservation with property owner rights through voluntary agreements.
