642-644 3rd Ave, San Francisco, CA 94118

The property at 642-644 3rd Avenue in San Francisco's Inner Richmond district is a two-unit, two-story multi-family residential building constructed in 1905, currently owned by the Wilbur Foo Lim Lew Qtip Trust. The building has undergone several significant maintenance and repair projects over the past decade, most notably a sewer replacement in May 2023 and furnace/duct work replacements in early 2018, which were undertaken to address several building violations issued in November 2017.

These violations highlighted multiple safety and maintenance issues that were subsequently resolved by February 2018, including problems with stairs, ceilings, electrical systems, duct insulation, and mold/mildew, as well as lead hazard concerns. The building has experienced various maintenance and safety-related issues over the years, including a 2019 complaint about excessive noise ("jet engine" sounds) and historical work including reroofing (2012) and sidewalk repairs (2005).

More recent service requests from 2020 to 2024 have primarily involved external matters such as street cleaning, abandoned vehicles, tree maintenance, and parking violations, rather than direct problems with the building itself. A notable tree-related service request from October 2021 indicated that while the tree had an extensive canopy, it was not considered an urgent or immediate safety hazard, according to utility arborist inspection. The property appears to be well-maintained in terms of resolving past violations, with all recorded building permits being marked as complete and no active violations currently on file.
