5631 California St, San Francisco, CA 94121

The Loi Family Trust owns this two-unit, two-story multi-family residential building located at 5631 California Street in San Francisco's Central Richmond neighborhood. Built in 1915 and classified as a Flats & Duplex structure, this property has experienced several notable incidents over the past decade. The most serious concern was a carbon monoxide detector activation in early 2020, though no carbon monoxide was detected and there were no civilian injuries reported.

Prior to that, the building had a false alarm activation of an alarm system in 2019. The property's maintenance history includes multiple reports of illegal postings in mid-2020, which were resolved, and a more significant 2016 incident involving sidewalk infrastructure problems, where approximately 100 square feet of damaged/uneven sidewalk and 9 linear feet of unpermitted driveway were documented. Earlier issues included a 2015 streetscape cleaning matter involving loose garbage, and a report of an abandoned vehicle in 2010 that was resolved when the vehicle was no longer present at the location.

The only building permit on record is a street space permit from 2011 with a nominal cost of $1.00. The building's incident history shows periodic maintenance and safety checks, though concerns about various urban infrastructure elements such as sidewalks, street cleaning, and illegal postings have arisen over the years. The most recent safety-related incidents were the detector activations in 2019-2020, while earlier structural issues were primarily related to exterior elements like sidewalks and street conditions.
