819 37th Ave, San Francisco, CA 94121

The two-unit, two-story multi-family residential building at 819 37th Ave in the Outer Richmond, owned by Wong Lew Gam & Mei Fung Liv, was constructed in 1945 and has undergone several notable maintenance and infrastructure developments over the years. Most recently, in April 2024, the property underwent plumbing work involving the replacement of a 4-inch sewer line connecting the front building to the house trap.

This improvement follows a concerning series of sewage backup incidents that occurred between February and May 2020, during which five separate sewer-related issues were reported and subsequently resolved by PUC Sewer Operations. The building received exterior maintenance in 2011 when vinyl siding was installed on the left and back walls at a cost of $12,229, though this work did not involve any structural changes and was not visible from the street.

The property's location has experienced recurring parking-related issues, with multiple incidents of driveway blocking documented between 2019 and 2023. Notable cases include three consecutive parking violations in August 2020, two additional driveway blocking incidents in September 2023, and several other related complaints, though most were resolved through citations or police intervention. A concerning trend was observed in April 2020, when there were four consecutive sewage backup incidents reported within that month alone, indicating a temporary but significant plumbing challenge that appears to have been addressed through subsequent infrastructure improvements, including the recent sewer line replacement completed in 2024.
