Los Angeles FAQ
Can my property be made an HCM without my consent?
Yes. Owner consent is not required. Anyone may nominate, and the Commission and Council can designate over an owner's objection if findings support significance under LAMC Section 22.171.7.
Does HCM status freeze the property?
No. Owners may use, lease, sell, and reasonably alter HCMs. Major changes to character-defining features require a Certificate of Appropriateness, but interior remodels and routine maintenance generally do not.
South San Gabriel FAQ
How do I nominate a property as a county landmark?
Submit a nomination form to the Department of Regional Planning describing significance. The Historical Landmarks Commission reviews, holds a hearing, and recommends action to the Board of Supervisors for designation.
Does landmark status freeze my property in time?
No. You can renovate, but exterior changes require Director of Regional Planning approval under Title 22.124. Routine maintenance, interior work, and code compliance upgrades typically proceed without full Commission review.
