144 Cortland Ave, San Francisco, CA 94110

The two-family residential building at 144 Cortland Ave in Bernal Heights, owned by the Chanthanom Ounkeo Family Trust, was constructed in 1988 following the demolition of a single-family dwelling in 1986. This two-story flats and duplex structure has undergone several significant improvements over the years, with the most recent major HVAC upgrade occurring in 2016 when a new furnace was installed.

The building has seen consistent maintenance and modernization efforts, including the installation of a 2.94kW solar panel system in 2013, water heater replacement in 2010, reroofing in 2013, and a garage door replacement in 2012. Earlier structural improvements included stair reconstruction and joist replacement completed in 1989. The property has experienced recurring issues with abandoned vehicles in the vicinity, particularly evident in 2024-2025 with multiple reports to parking enforcement, though these vehicles were typically gone upon arrival of the authorities.

There have been two instances of street debris requiring Recology intervention in late 2024, involving abandoned electronics and a refrigerator. While these external maintenance issues have required attention, they primarily relate to public spaces rather than the building itself. The property's documented history shows regular upkeep and modernization of essential systems, with no recorded building code violations or safety concerns directly associated with the structure.
