Program Overview

Los Angeles’s remarkable architectural and cultural heritage boasts examples of styles from the Arts and Crafts movement to mid-century modern. Historic places throughout the region contribute to the City’s rich social and cultural life.  

The Los Angeles City Planning Department’s Office of Historic Resources (OHR) works to protect, enhance, and revitalize the City’s historic places through its comprehensive, state-of-the-art, and balanced historic preservation program.
