650-652 Natoma St, San Francisco, CA 94103

The 2-story, 4-unit multi-family residential building at 650-652 Natoma Street in the South of Market neighborhood, owned by the Jean Wen Tsing Khoo Trust, was constructed in 1912 and has undergone several significant improvements over the years. The most recent building work includes street space permits issued in 2017 and 2006, and the installation of new vinyl siding in the lightwell walls in 2016 at a cost of $7,000.

In 2015, a permit for installing Hardie fiber cement was cancelled, and prior major work included a completed reroofing project in 2009 costing $6,000, and foundation work in 1999. The building has had three routine housing inspections on record, with some violations noted in 2007 including the need for fire extinguishers and seismic bracing for the hot water heater, all of which were abated within one week.

A health and safety inspection was conducted in 2011 and resolved. The property has experienced recurring street cleaning issues in recent years, with multiple 311 calls between 2022-2024 reporting various cleanliness concerns including human waste, animal waste, and general garbage, with the most recent open case regarding human waste or urine filed in November 2024 indicating ongoing challenges with the immediate area around the building. Additionally, two fire-related incidents were recorded, though neither involved civilian injuries or was related to the building's condition or systems.
