About This Lot

As of December 2025

Located east of Lake Avenue and just south of East Altadena Drive, this approximately 8,135 square foot lot (per the LA County Assessor) presents a rare opportunity to build anew in a serene Altadena neighborhood. The property is zoned LCR175, supporting low-density residential development. The previous residence, a 4-bedroom, 2-bathroom single-family home with approximately 1,800 square feet of living space, was unfortunately lost in the Eaton Canyon Fire. Prior to the fire, the site had established connections to sewer, water, electricity, and gas.Phase 2 of the debris removal process has been completed.The lot is situated near several popular hiking trails, including the Altadena Crest Trail and the Sam Merrill Trail, offering access to the natural beauty of the San Gabriel Mountains. Interested buyers are advised to independently investigate potential future uses and parcel remediation processes with the County and applicable government agencies. Please do not walk on the property.
