Altadena Heritage formed in the early 1980s when many beautiful old homes and mansions were being demolished and replaced with tract developments. Altadena’s architectural heritage was in peril. At the time, Los Angeles County had no historic preservation ordinance, so AH decided that its first time-critical task was to advocate for preservation. As an advocacy organization, AH has never shied away from taking a stand on issues affecting our town and its governance. We organize educational programs to inform Altadenans and advocate for Altadena with the county on issues such as public landscaping, building standards, and watershed management.
