3889 20th St, San Francisco, CA 94114

The property at 3889 20th Street is a two-story, three-unit multi-family residential building constructed in 1925, currently owned by the Dufrene Morales Family Trust. The building has a history of various improvement attempts and compliance issues, with the most recent significant maintenance work being the conversion from overhead to underground electrical service completed in 2003. A notable series of violations and complaints arose between 2012 and 2022, including multiple fire safety concerns (combustible storage and fire proofing issues) and water heating problems in 2022, though all these issues were officially abated by May 2023.

The building underwent at least two routine inspections in 2002 and 2007, and there have been several attempts to modify the building's unit configuration over the years, including a 1995 effort to legalize a lower apartment and a cancelled attempt in 1986 to legalize a fourth apartment. The property has experienced recurring maintenance challenges, particularly regarding water heating systems, with multiple complaints about inadequate hot water temperatures. More recently, there has been a documented issue with the door signal device that was filed in September 2022 and resolved in May 2023.

The building has undergone various roofing work in the 1990s, though records show some of these permits eventually expired or were cancelled. The property is currently experiencing some external maintenance challenges, as evidenced by multiple graffiti incidents recorded in late 2024, particularly on the sidewalk in front of the property, though these were promptly addressed by city services. A single smoke detector activation incident was recorded with no fire or injuries reported.
