2731 23rd St, San Francisco, CA 94110

The property at 2731 23rd Street is a two-story, three-unit multi-family residential building located in San Francisco's Inner Mission neighborhood, constructed in 1900 and classified as a Flats & Duplex building. The building has a significant history of maintenance and safety issues, particularly in recent years. Most notably, there were serious habitability concerns in 2019, including mold/mildew, floor covering problems, and general dilapidation, which were not fully resolved until November 2024.

Earlier violations included illegal construction of a roof deck in 2009-2012, heating system deficiencies in 2008, and electrical work done without permits. The building has undergone several permitted improvements, including a reroofing project in 2014, installation of a new heating system in 2008, and various structural modifications between 2011-2012 to address code violations. Recent maintenance issues have persisted, with multiple 311 calls in 2024 regarding sidewalk defects, fallen trees, and multiple instances of vehicles blocking driveways.

The property has shown recurring problems with building maintenance and habitability, with past complaints documenting issues such as mold, inadequate heating, and improper maintenance of interior surfaces. These violations have generally been addressed through various building permits and inspections, though the resolution of recent complaints has often taken considerable time. The most recent planning record indicates an approved referral related to ExteNet services in 2018. The building's history suggests ongoing challenges with maintenance and code compliance, though many of the most pressing recent violations have finally been resolved as of late 2024.
