Historic Preservation Program

The County’s Historic Preservation Program (“Program”) is comprised of its:

  • Historic Preservation Ordinance (HPO) which was adopted September 1, 2015, and established criteria and procedures for the nomination, designation and review of work on landmarks and property located within historic districts.

Additional information about the Program may be found in the Program flyer and presentation of the Program’s December 6, 2023 public information meeting

The Program applies only to unincorporated areas of Los Angeles County and to County owned land. Use the Jurisdiction Lookup application to determine the jurisdiction of a property.  For property located within the City of Los Angeles, please contact their Office of Historic Resources.

The County only administers its own Program.   For information about National and State registration programs, please contact the California Office of Historic Preservation.
