539-543 Union St, San Francisco, CA 94133

The 6-unit apartment building at 539-543 Union Street in Telegraph Hill is a three-story structure built in 1909 and currently owned by the Alson Tom Trust 2008. The building has undergone several notable maintenance activities and experienced multiple violations over the years, with the most significant issues occurring between 2000 and 2011. In the early 2000s, there were serious concerns about lead paint hazards, with complaints filed in 2001 and 2010, though these were eventually abated in September 2011. The property has a history of fire safety and emergency preparedness violations, particularly in 2005, when issues were identified regarding fire extinguisher maintenance, fire door closures, egress obstruction, and gas utility shutoff tools, though all these violations were resolved by December 2005.

A ceiling collapse was reported and resolved in 2001. The building's maintenance history shows roofing work was performed in 1993 and 1999, though these permits have since expired. More recently, the property has experienced recurring issues with street cleanliness and debris removal, particularly in 2024, with multiple reports of abandoned garbage and debris on the street and sidewalk. Between January and December 2024, there were several reports of garbage and general cleaning needs, including cases of bagged debris and blocked sidewalks.

The property also had a water or steam leak incident recorded, though no civilian injuries were reported. The building's most recent documented street space permits were issued in 2011, suggesting some time since any major structural work was performed. Additionally, there was one street space and sidewalk permit issued in 2007, though the specific purpose of these permits is not detailed in the records. While many of the historical violations have been addressed, the recent pattern of street cleaning issues may indicate ongoing challenges with building maintenance and property management in the surrounding area.
