2930-2934 21st St, San Francisco, CA 94110

The 4-unit, 2-story multi-family residential building at 2930-2934 21st Street in the Inner Mission, owned by 21st St Apts LLC, has a significant history of maintenance issues and violations, particularly between 2017 and 2023. Most notably, in 2017, multiple serious violations were documented including mold and mildew on walls and ceilings, interior surface damage, and weatherproofing deficiencies, which were ultimately abated by September 2019.

The building experienced recurring water-related problems, with complaints of water damage, roof leaks, and mold reappearing in 2022, though some repairs were documented through building permits, such as rear stair repairs in 2023. The property has undergone several maintenance and improvement projects over the years, including multiple window replacement projects (2003-2009) converting wood frames to vinyl, roof work in 1989, and various siding repairs.

A concerning pattern emerged in late 2022 with multiple complaints regarding damaged windows, holes in walls, peeling paint, and safety issues, followed by a routine inspection in October 2022 that required stair repairs. More recently, in 2024, there have been multiple reports of abandoned items and debris around the property, with 12 separate reports of various debris including furniture, appliances, and mattresses between December 24-31, 2024, though these reports are primarily street cleaning issues rather than building maintenance concerns. While some repairs and improvements have been made, the building's history shows periods of significant maintenance challenges affecting resident habitability and building systems.
