571 37th Ave, San Francisco, CA 94121

The two-unit residential building at 571 37th Avenue in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1986, currently owned by Kee Lum & Lily Y Won Family. The building's documented history shows relatively few significant events, with most activities occurring during the 1980s and mid-2000s.

The property was previously demolished in late 1984 (with two demolition permits issued on November 15 and 16), before being reconstructed into its current form. In 2000, there was an expired permit for sidewalk repair work, though there are no records of subsequent issues with the sidewalk.

More recently, there was a concerning complaint filed in October 2022 regarding a bad smell coming from the downstairs plumbing, which was directed to Housing Inspection Services, though the status is marked as "Not Active." The building has had several 311 calls related to the property, mostly concerning street and sidewalk issues. These include a parking enforcement call for a driveway blocking incident in January 2025 (resulting in an officer response but unable to locate the vehicle), a sidewalk parking complaint in December 2019 (which could not be validated by responding officers), and an abandoned vehicle report in October 2015 (for a black Toyota Corolla that was gone upon arrival of authorities). There were two incidents in April 2015 involving public works matters: one related to a missing sewer vent cover at 567 37th Avenue, and another concerning loose garbage that was subsequently resolved.
