Altadena Makes History With County’s First-Ever Historic District Designation

The Los Angeles County Board of Supervisors on Tuesday approved the County’s first-ever historic district and landmark designation, officially recognizing the northern portion of Altadena’s Historic Highlands neighborhood as a County Historic District.

The Board’s unanimous vote amends Title 22 (Planning and Zoning) of the Los Angeles County Code to include the Historic Highlands Historic District, encompassing 77 parcels primarily made up of early 20th-century single-family homes. The area is renowned for its architectural styles, including Craftsman, Spanish Colonial Revival, and Tudor homes, reflecting the community’s growth during the 1920s suburban expansion.

“This is a proud moment for Altadena,” said Supervisor Kathryn Barger, who represents the area. “By formally recognizing the Historic Highlands as the County’s first historic district, we are setting a precedent for celebrating the history embedded in our unincorporated communities.”

The landmark decision follows years of community advocacy and the recommendations of both the Historical Landmarks and Records Commission and the Regional Planning Commission. More than 50 percent of property owners supported the designation, which aims to preserve the neighborhood’s historic character while allowing for thoughtful modernization and future growth.

“Altadena recently suffered a great loss, and it is especially meaningful to take this action now to ensure that the community’s historic treasures are preserved,” Barger added. “Today’s vote affirms our commitment to honor Altadena’s past while safeguarding it for future generations.”

While the Historic Highlands was not impacted by the recent Eaton Fire, residents have long expressed concern over maintaining the historic integrity of the area’s streetscapes and homes.

With the adoption of the ordinance now in effect, the Historic Highlands Historic District will be officially entered into the County Register. County officials will begin notifying affected property owners of the new designation and guidelines for preservation.
