140 Locksley Ave, San Francisco, CA 94131

140 Locksley Avenue is a two-story, four-unit multi-family residential building located in Forest Knolls and built in 1961, currently owned by Dennis M & Marisa Koenig 20. The building has a documented history of addressing significant structural concerns, including landslide repairs in 1998 and 1999 involving a buried concrete retaining wall, with these being the most substantial construction-related interventions on record. In March 2003, the property underwent a series of safety violations related to fire safety and security, including the need for smoke detectors, self-closing exterior doors, and removal of combustible storage from the garage; however, all these violations were resolved by September 2003.

The building has been subject to regular housing inspections, with the most recent routine inspection occurring in August 2017. Recent maintenance and infrastructure issues have emerged, particularly in 2024, with reports of water quality concerns (discolored water), tree root problems affecting sidewalks, and sidewalk defects. Multiple tree maintenance requests were filed and resolved in 2023, suggesting ongoing attention to landscaping maintenance.

The most recent building-related concerns involve infrastructure issues such as water quality and sidewalk maintenance, rather than safety or structural problems. Two fire-related incidents were recorded, but neither involved civilian injuries or significant damage, primarily relating to assistance and smoke removal. The property's permit history shows minimal residential improvements beyond the original 1993 window installation (which expired) and the previously mentioned landslide repairs.
