547 23rd Ave, San Francisco, CA 94121

The four-story multi-family residential building at 547 23rd Avenue in the Central Richmond neighborhood, owned by Tu Shuzhen, has been experiencing persistent maintenance and structural issues since its construction in 2003. The building, which contains two units, has faced recurring water damage problems over several years, including significant violations in 2019-2023 related to water leaks, mold, and ceiling issues. Most recently, in October 2024, active complaints reported mold presence, leaking ceilings, pest issues (including mice), and staircase code compliance concerns.

Building maintenance history reveals multiple repair efforts, with the most recent permit from November 2024 addressing sheetrock repairs, mildew removal, flooring replacement, drainage issues, and smoke detector reinstallation, totaling $1,500. Earlier historical records indicate various construction challenges, including foundation work in 2004, window modifications in 2003, and multiple permits related to shoring and structural adjustments in the early 2000s. The property has also experienced building code violations related to heating systems, deck repairs, and water damage, with most violations being abated by June 2023.

External issues have been documented through 311 calls regarding garbage, debris, and sidewalk maintenance concerns. Building safety incidents include two fire department responses, one for a gas leak and one false alarm, neither resulting in civilian injuries. Despite numerous repair attempts and permit approvals, the building continues to exhibit ongoing maintenance challenges, particularly regarding water damage and its effects on building conditions and resident comfort.
