Determination of eligibility or listing for the National Register or California Register results in legal protections for the property or district. For example, environmental review may be required under CEQA if a project may cause a substantial adverse change to historic resources through demolition or alteration. Also, certain state laws, such as Senate Bill (SB) 9, do not apply to historic properties or districts. The Mills Act allows property owners to pursue tax incentives for listed resources through a contract with the City to reduce property taxes in exchange for agreeing to rehabilitate their historic resource. Lastly, historic resources are subject to additional codes including the City’s Historic Preservation Ordinance (Municipal Code Section 27.66), the California Historical Building Code, and the Secretary of the Interior's Standards for the Treatment of Historic Properties.
