171 Langton St, San Francisco, CA 94103

The 10-unit, three-story apartment building at 171 Langton Street in the South of Market neighborhood, owned by Langton Global Investment L, was built in 1915 and has experienced several significant maintenance and safety issues over recent years. In 2017-2018, the building faced substantial violations including problems with smoke detectors, carbon monoxide alarms, general dilapidation, mold, electrical issues, and plumbing problems, particularly in Unit 2, which had severe water leakage affecting multiple rooms and persistent electrical problems. These violations were addressed through multiple building permits, including window replacements and deck repairs.

The building also underwent several necessary maintenance projects, such as window replacements (2018, 2013, 1997), deck repairs (2018, 2009), and roof work (2006). The property has a concerning history of fire safety violations, with multiple issues reported between 2016-2022 including problems with fire extinguishers, alarm systems, and blocked exits. A pattern of fire alarm activations without actual fires has been recorded, along with a carbon monoxide detector activation. More recently, in 2022, there were three fire safety complaints related to extinguishers and alarm systems, all of which were corrected.

The building has also faced structural and maintenance issues, as evidenced by complaints regarding a missing stairwell window, peeling walls, and electrical problems. In 2020, there was a violation related to building owner contact posting requirements. A notable incident occurred in late 2024 with multiple reports of garbage and debris issues near the property, though these are external to the building itself. The building's recent history shows a pattern of addressing violations, though many issues required multiple permits and inspections to resolve, indicating ongoing maintenance challenges.
