172 Raymond Ave, San Francisco, CA 94134

This two-unit residential building located at 172 Raymond Avenue in Visitacion Valley was constructed in 1910 and is currently owned by David S. & Elizabeth Ma. The property has experienced numerous significant issues over the past two decades, most notably an unresolved code enforcement case (as of 2010) regarding unauthorized unit modifications and additions.

The complaints from July 2010 detailed the unauthorized conversion from a single-unit to a two-unit building, including unpermitted construction of additions, improper gas water heater installations, and various safety code violations such as inadequate fire-resistant materials. Prior to this, the building faced various safety and maintenance concerns including front stairway violations (2004-2005), sewage overflow incidents (2009), and living conditions issues such as pest problems and water leaks (2010-2011). Historical records show that the building also underwent a series of repairs in the early 1990s following fire damage, including window, roof, and drywall replacements.

More recent history (2024-2025) shows ongoing issues in the vicinity of the property, including multiple reports of garbage and debris violations, with several cases involving furniture and electronics. There are also current concerns regarding sidewalk conditions (as of December 2024) and parking violations near the property. The property has a documented history of ventilation problems (1994), roof issues (2004-2005), and stairway safety concerns (2004-2005), though many of these historical problems appear to have been addressed through various building permits and repairs. A recent complaint from 2024 remains open regarding park services area signage, while multiple recent 311 calls primarily relate to street-level issues outside the building, such as debris removal and parking enforcement.
