Defensible Space Law: effective July 1, 2021 –Defensible space is the term for a buffer zone that homeowners create between a structure on the property and any flammable grass, trees, shrubs, or wildland area that surround it. Existing state and local laws require certain property owners to maintain defensible space on their property. Sellers of such properties will need to provide documentation that their property is in compliance with defensible space laws, or buyers will be required to agree to obtain such documentation of compliance in the future.
