1639-1641 Leavenworth St, San Francisco, CA 94109

The two-unit, two-story multi-family residential building at 1639-1641 Leavenworth Street in Nob Hill was constructed in 1911 and is currently owned by Joan M Lee, Watson G, and Walla. The building's maintenance record shows relatively minimal internal work, with only one significant plumbing permit issued in November 2018 for gas line repair and water heater replacement, though there was also a street space permit issued in August 2011.

The most notable aspects of the building's history pertain to external conditions and street-level maintenance issues. The property has accumulated a series of 311 calls over the past 15 years, with the majority relating to street and sidewalk cleaning concerns. There were three reported incidents involving human or animal waste (in October 2019, January 2020, and May 2022), and other cleaning issues including hazardous materials (glass) in April 2022, garbage incidents in December 2020, and various general cleaning matters.

An instance of graffiti was reported and resolved in September 2014, and multiple general cleaning calls were made in 2009, 2014, and 2020. The most recent incident involved garbage and debris on the street in October 2024, which has since been resolved. While these maintenance issues primarily relate to the surrounding area rather than the building structure itself, the frequency of street-level cleaning calls suggests ongoing challenges with the immediate environment around the property.
