154 San Carlos St, San Francisco, CA 94110

The two-unit residential building at 154 San Carlos Street in the Inner Mission, owned by Tang Wai Fong&danny M& Mari, has a documented history of maintenance and safety issues spanning several decades. Built in 1915, this two-story flats and duplex structure has experienced multiple significant problems, particularly evident in the period from 2005 to 2009, when numerous violations were recorded, all of which were ultimately abated in April 2009. These violations included urgent safety concerns such as damaged stairs, fire safety issues including combustible storage, lead paint hazards, plumbing problems, and various interior surface deficiencies.

In 2016, another concerning complaint was filed regarding a deteriorating rear deck, though this was marked as not active. More recently, from late 2023 through 2024, there have been numerous reports related to garbage and debris around the property, with multiple cases of loose garbage documented between November 2023 and November 2024. Two specific sanitation issues were highlighted, including human waste or urine reported in July 2024, which required attention to a property's drainage-related safety concern. The most recent building-related complaint in 2024 involved parking violations on the sidewalk, which resulted in a citation.

The building's maintenance history includes some remedial work, such as a 2006 permit for stair repairs in response to a 2005 complaint, indicating some level of responsiveness to safety issues, though many problems persisted through the late 2000s. A building fire incident was also recorded, though it occurred under circumstances categorized as "Unintentional" with no civilian injuries reported. The property has shown patterns of neglect over the years, with particular clusters of violations and complaints regarding safety and maintenance issues during the 1990s and mid-2000s. While many of the historical violations were formally abated, the recent pattern of sanitation complaints suggests ongoing maintenance challenges, though these are primarily related to exterior and common area conditions rather than structural or safety issues.
