771-773 19th Ave, San Francisco, CA 94121

The property at 771-773 19th Avenue is a three-story multi-family residential building constructed in 1922 in San Francisco's Central Richmond neighborhood, containing two units and currently owned by Kwan K Lee & lan H Lee (2009). The building underwent a significant vertical addition in 1991 costing approximately $121,900, followed by fire safety upgrades in 1993 including the installation of fire sprinkler systems. More recently, in December 2008, both furnaces in the building were replaced, representing the most recent major systems upgrade on record.

The property has experienced several maintenance and incident issues over the past decade. Most notably, in December 2023, there was a report of damaged property, though this case was closed administratively due to technical issues. In June 2013, there was a sewage backup incident that required attention from PUC Sewer Operations and was subsequently resolved.

The building's external environment has faced various challenges, including a collapsed sidewalk documented in October 2016 covering approximately 190 square feet, which required attention from the Department of Public Works. There have also been multiple reports of abandoned vehicles in the vicinity between 2016 and 2011, though these were typically resolved quickly as the vehicles were gone upon inspection. More routine issues include two instances of driveway blocking in 2018 and 2019, and one instance of encampment items requiring removal in 2021, though in these cases no violations were found or the issues were resolved swiftly.
