1234 20th Ave, San Francisco, CA 94122

The 4-unit, 2-story multi-family residential building at 1234 20th Avenue in the Central Sunset neighborhood was built in 1974 and is currently owned by Liu Ai Hong. The building's maintenance record shows attention to basic infrastructure, with completed re-roofing work performed in 2017 at a cost of $9,800, while a proposed soft-story retrofit project from late 2017 was withdrawn.

The property has undergone regular housing inspections in 2001, 2003, 2009, and 2014, with the most significant issues arising from the 2003 inspection, which identified multiple fire safety concerns including the need for fire extinguisher recharging, smoke detector improvements, garage storage issues, and gas meter instructions - though all these violations were officially abated by December 2003. Recent records from 2022-2024 show several street-related issues near the property, including reports of waste on public sidewalks, though these were municipal street cleaning matters rather than building-specific problems.

There is a notable pattern of abandoned vehicle reports in the vicinity between 2017-2018, primarily involving motorcycles, indicating some ongoing parking enforcement challenges in the area. While the building's historical violations and complaints were primarily related to fire safety and emergency preparedness issues from 2003, these appear to have been resolved, and there have been no recorded building violations or major complaints in the past decade.
