155 20th Ave, San Francisco, CA 94121

The 4-unit, 2-story apartment building at 155 20th Ave, owned by Auyeung Mabel K S C Living, has undergone several significant maintenance and construction activities since its 1961 construction. Most recently, in October 2022, the building received a $19,000 reroofing project, following an earlier 2003 roofing project ($8,000). In 2015, there was a substantial temporary shoring and underpinning project ($20,000) associated with excavation and construction work.

The building experienced multiple violations in 2006, primarily related to fire safety issues including non-compliance with fire extinguisher maintenance requirements, combustible storage concerns, and problems with fire escape ladders, though all these violations were abated by June 2006. More recent concerns include two complaints from 2018 regarding unauthorized construction work and drainage issues affecting neighboring properties, and a 2008 incident involving raw sewage leakage from the garage. The property has undergone regular routine inspections, with records showing attention to various maintenance issues including mold/mildew removal and water damage repairs, all of which were addressed according to records.

Fire department responses show three incidents: a water evacuation, a carbon monoxide detector activation (with no CO found), and a false alarm, none of which resulted in civilian injuries. The building's location has experienced recurring issues with parking enforcement, including multiple reports of abandoned vehicles and sidewalk parking violations between 2016 and 2023. While these parking issues are not directly related to building conditions, they may impact tenant convenience. The property's maintenance record shows a pattern of addressing violations and making necessary repairs, though some complaints have been noted as "Not Active" with no clear resolution date.
