Los Angeles County designates historic landmarks under Title 22.124, with the Historical Landmarks and Records Commission recommending Board of Supervisors approval for properties of local, state, or national cultural significance.
Title 22.124 of the LA County Code creates the Historical Landmark and Records Commission and the procedure for designating county landmarks in unincorporated areas. An owner, civic group, or commissioner may nominate a property, and the Commission evaluates significance based on architecture, historical event association, master architect work, or cultural community ties. The Board of Supervisors makes the final designation. Landmark properties receive design review oversight, demolition stay protection, and Mills Act eligibility. Examples include the Pio Pico Mansion vicinity, Watts Towers area resources, and Topanga rural historic structures. Incorporated cities such as Los Angeles, Pasadena, and Long Beach run separate Historic-Cultural Monument or landmark programs.
Altering or demolishing a designated county landmark without Commission review and Director of Regional Planning approval voids permits, stops work, and exposes owners to restoration orders and civil penalties under Title 22.124.
