142-144 Highland Ave, San Francisco, CA 94110

The property at 142-144 Highland Avenue is a two-unit, two-story multi-family residential building located in Bernal Heights, built in 1915 and currently owned by Emma Lara. The building has experienced several significant maintenance and safety issues over the years, most notably in 2009-2017 when complaints were filed regarding an illegally converted ground floor unit, including concerns about improper occupancy, lack of required smoke detectors, inadequate emergency egress, and unauthorized electrical and plumbing work. These violations were ultimately addressed and abated by July 2017.

The building underwent a notable solar energy upgrade in 2017, with multiple PV module installations totaling 4.32 kW, along with the installation of separate electrical metering for each unit in 2005. Recent history shows numerous parking enforcement issues in late 2024, with multiple citations for sidewalk parking and other violations, though these are not directly related to the building's condition. The building had several maintenance and safety improvements completed in 2017, including repairs to interior surfaces, smoke detector replacement, and window repairs, following a June 2017 inspection that identified various maintenance issues.

An older renovation in the mid-1990s included floor joist and deck replacements, and the removal of non-bearing walls. While the building has experienced multiple false alarm incidents and some electrical equipment issues, none have resulted in civilian injuries. The property maintains two residential units as per its original classification, though historical records indicate unauthorized modifications that were later addressed through enforcement actions.
