919-921 Leavenworth St, San Francisco, CA 94109

The 5-unit multi-family residential building at 919-921 Leavenworth St, owned by Ying C & Marilyn Kwan Revoc, has experienced several significant maintenance and safety issues over its history since being built in 1919. Most recently, in early 2023, the building underwent plumbing work involving the replacement of a house trap and approximately 25 feet of sewer line, which was completed successfully. The property has faced recurring issues with water management and maintenance, including two related complaints in 2014 about flooding in common areas and leaks causing mold and mildew, though these were resolved within a few months.

A notable cluster of violations occurred in July 2011, involving multiple interior issues including damaged walls, floor covering problems, inadequate lighting, and issues with windows - all of which were subsequently addressed. The building's maintenance history shows regular updates to essential systems, including the installation of stairwell lighting in 2014 and various plumbing upgrades between 2008 and 2023. However, there have been some concerning incidents, such as a 2007 complaint about wet "lint" sludge flowing onto the street, which was addressed in 2008, and a period of unauthorized remodeling work reported in late 2008.

Security-related concerns were documented in 2003 regarding exterior door self-closing devices, and more recent complaints in 2024 show recurring issues with abandoned furniture and debris on the property, though these are street-related rather than building maintenance concerns. Two documented smoke detector activations occurred at the property, though neither resulted in actual fires or civilian injuries. The building's owner has generally responded to maintenance issues as they arise, with most violations being resolved within reasonable timeframes, but the frequency of historical complaints suggests periodic challenges in maintaining building systems and addressing resident concerns.
