3546-3548 22nd St, San Francisco, CA 94114

The property at 3546-3548 22nd Street is a two-story, four-unit multi-family residential building with ground floor commercial space, constructed in 1900 and currently owned by Farnsworth Richerson. The building has undergone numerous significant improvements and maintenance work over recent years, with particular attention paid to building safety and accessibility. Recent commercial tenant improvements completed in 2023 include the installation of shampoo chairs and laundry facilities in the commercial space, along with associated electrical and plumbing work.

Between 2018 and 2021, major projects included the installation of a fire sprinkler system, renovation of exterior stairs for accessibility, dry rot repair, and various electrical upgrades including a new fire alarm system. The building underwent substantial ground floor unit improvements in 2018, including new fire safety systems, kitchen and bathroom installations, and comprehensive electrical rewiring. The property has a history of infrastructure maintenance issues, particularly in the late 2000s, with several violations related to unauthorized sewer work and foundation work that blocked public pathways. These violations were ultimately abated by 2009.

More recent complaints from 2019 raised concerns about exterior plumbing, electrical, and venting installations, though these issues were subsequently addressed and marked as inactive. The building's systems have generally been well-maintained, with documented improvements including furnace installations, bathroom renovations, and sewer lateral replacements. Recent 311 calls from 2024 primarily relate to street-level maintenance issues such as garbage can overflow and cleaning needs, rather than building-specific concerns. The property's planning records show successful legalization of previously unpermitted units and improvements, including the establishment of a ground-floor commercial unit converted from office to personal service use.
