3233-3235 21st St, San Francisco, CA 94110

The 3233-3235 21st Street property is a two-story, four-unit multi-family residential building constructed in 1900 in San Francisco's Inner Mission neighborhood, currently owned by the Yap Asuncion T Trust. The building has undergone significant recent improvements, with a major renovation completed in 2023 costing $138,000 that included remodeling three bathrooms and a kitchen, replacing windows, installing new flooring, upgrading electrical systems, and repairing entrance hallways and front stairs.

The property has a documented history of maintenance and safety issues, particularly in the 2000s and early 2010s, including multiple building violations related to unpermitted stair replacements (2003), a sewage overflow incident (2006), and interior problems that required significant repairs including the replacement of plastered walls, ceilings, insulation, and kitchen cabinets (2011). Fire safety has been a recurring concern, with multiple violations and complaints regarding alarm systems, sprinkler systems, and blocked exits recorded between 2015 and 2024, though recent fire safety violations from late 2023 and 2024 have been abated. The building's maintenance history shows regular attention to structural and safety issues, with several major electrical upgrades (2011-2023), roof replacement (2013), and stair repairs.

A tenant buyout occurred in February 2023 with one tenant reportedly receiving $100,000. Recent 311 calls from 2024 have primarily concerned exterior issues such as graffiti and sidewalk defects, though these are not directly related to building safety or maintenance. The building has maintained an active maintenance record since the early 2010s, with most recent permits and violations being promptly addressed, suggesting improved management practices in recent years compared to the more problematic period of the 2000s and early 2010s.
