4736 Mission St, San Francisco, CA 94112

The 4-unit, 2-story apartment building at 4736 Mission Street, owned by Thongvichit 2002 Trust, has a long history dating back to 1907 and has undergone several significant maintenance and security upgrades over the years. Most recently, in 2024, there have been multiple reports of garbage and debris around the property, with particular incidents of human waste or urine reported in September and November.

The building experienced water heating system issues in 2004, with complaints about lack of hot water lasting two years, though subsequent inspections showed resolution of this problem. Between 2017 and 2020, several fire safety concerns were documented, including issues with fire escape ladders, fire extinguisher maintenance, and sprinkler systems, with the most recent complaint about sprinkler systems being referred to the Department of Building Inspection in late 2020. The building has undergone various improvements, including the replacement of security gates in 2010 (though one installation occurred without proper permits), sidewalk and structural work in 2006, and electrical improvements in 2007.

Historical inspection records show attention to safety concerns, with routine inspections in 2000, 2004, and 2017 identifying various issues that were subsequently addressed, including stair repairs and egress obstructions. Recent months have seen ongoing maintenance challenges, as evidenced by multiple 311 calls regarding garbage, debris, and parking violations in late 2024. A 2005 complaint about exposed electrical wires near the building entrance was issued violation notice but was resolved the following year.
