1643-1645 Leavenworth St, San Francisco, CA 94109

The two-unit residential building at 1643-1645 Leavenworth Street, owned by William B and Roberta Fazande, is a two-story flats and duplex structure built in 1902 in San Francisco's Nob Hill neighborhood. The property has undergone several permitted improvements over the years, with the most recent significant work occurring in 2015 when a $4,500 kitchen renovation was completed, including new tile flooring and wall repairs.

Earlier improvements include window replacements and vinyl siding installation to the rear of the building in 2000, and a reroofing project from 1992, though this permit is listed as expired. The property has experienced multiple street-level maintenance issues in its vicinity over recent years, with seven documented cleaning-related 311 calls between 2020 and 2024. These calls primarily involved reports of loose garbage, with the most recent occurring in March 2024 regarding human or animal waste.

Other external incidents in the surrounding area include a 2019 parking violation complaint (though the vehicle was not located), a non-offensive graffiti report on a nearby transit shelter platform, and a verified encampment check in September 2019 that found no encampment present. While these external maintenance issues have been addressed through the city's response mechanisms, they primarily relate to street conditions rather than building-specific concerns. The most recent building improvements and the absence of any documented building code violations or interior maintenance issues since 2015 suggest stable property maintenance practices, though the age of some earlier improvements (1992 roofing, 2000 window and siding work) may indicate these systems are now over 30 years old.
