40 Langton St, San Francisco, CA 94103

The two-unit residential building at 40 Langton St, owned by the Patricia Kiely Trust, is a two-story flats and duplex structure built in 1915 in San Francisco's South of Market neighborhood. The building's permit history shows two notable structural improvements: a significant roofing project completed in 2011 at a cost of nearly $10,000, and a proposed property line wall construction in 2015 that would have included two layers of fire-rated material, though this permit's final status is listed as "Filed." Of particular historical note, there was a fire incident in 1983 that required carpentry repairs throughout the building, though this permit was ultimately cancelled.

Recent activity around the property (2024) has been characterized by recurring issues with parking enforcement, with multiple reports of driveway blocking between April and September 2024, though officers were often unable to locate the offending vehicles. There have also been several street cleaning concerns, including reports of garbage, debris, and encampments, with mixed outcomes ranging from resolved cases to ongoing issues.

In January 2020, there were two complaints filed regarding construction noise violations, though these cases are now listed as not active. The most recent issues have been centered around external conditions rather than building-specific problems, with the property itself showing no significant structural or safety complaints in recent years.
