21-23 14th Ave, San Francisco, CA 94118

The two-unit, two-story multi-family residential building at 21-23 14th Avenue in the Lake-Presidio neighborhood, currently owned by Ching Munson Y & Doris E, has experienced several significant maintenance and safety issues since its construction in 1940. The most concerning historical incidents occurred in 2008, when the building faced multiple violations including mold/mildew problems, lead paint hazards, and window-related issues, all of which were abated by November 2008. That year also saw a sewage backup issue in November that was resolved by late November.

Prior to these incidents, a fire safety complaint in April 2008 noted concerns about smoke alarms, fire extinguishers, and second-floor windows. The building has undergone various maintenance and improvement work over the years, including a furnace replacement in 2021, electrical upgrades with an underground service conversion in 2003, and several plumbing-related inspections. More recently, there have been recurring sewer-related issues, with documented problems in 2022, 2021, and other instances.

Recent maintenance activities include Christmas tree removal in 2023 and repairs to sidewalk in 2003. The property has faced some exterior maintenance challenges, as evidenced by multiple 311 calls regarding flooding and sewer issues, and there were two reports of fallen trees in July 2024. While most historical complaints have been resolved, the pattern of sewer-related issues and exterior maintenance needs suggests ongoing infrastructure challenges.
