1645-1649 Sacramento St, San Francisco, CA 94109

1645-1649 Sacramento Street is a three-story, three-unit multi-family residential building located in Nob Hill, built in 1908 and currently owned by Ng Yee Kun. The building has experienced several significant maintenance and safety-related events over its history, with the most serious being a fire incident in 1990 that required repairs to one unit including sheetrock, painting, and roof work. This was followed by a roofing project in 1990, which subsequently expired.

In 2001, the building underwent a routine housing inspection that identified multiple violations including egress obstructions, interior surface issues, stair replacement needs, and concerns about lead paint, all of which were addressed and abated by August 2001. More recent concerns from 2011 focused on plumbing safety, specifically regarding hot water heater flue pipe slope and seismic bracing requirements, though these violations were also resolved by October 2011. The property has maintained a relatively low profile regarding major violations or incidents in recent years, with no active building violations recorded since 2011.

The most current issues have been limited to external and street-level concerns, as evidenced by 311 calls, with the most recent being reports of garbage and debris, illegal parking, and waste on nearby streets. These external issues have been consistently addressed and resolved by city services. The building's documented history suggests that while it has faced periodic maintenance and safety challenges, particularly in the early 2000s, these have been addressed through proper channels and permits, with no recent patterns of recurring violations or safety concerns within the building itself.
