Adopted by the California Legislature in 1976, the Mills Act gives local governments the authority to grant property tax relief to owners of qualified historic properties, including those that are owner-occupied and those producing income. In exchange for this relief, the property owners must agree, by contract, to maintain the properties in accordance with specific historic preservation standards and conditions. The overall intent of the legislation is to provide an incentive for owners to preserve and maintain a community’s historic resources.
