Augrented Insights Report

The 4-unit multi-family residential building at 462 20th Avenue in the Central Richmond neighborhood is a 2-story structure built in 1971, currently owned by Richmond & Sunset Inc. The building's most recent significant maintenance work was completed in 2016 with a reroofing project costing $9,500.

Of particular note is a cluster of fire safety violations documented in January 2003, which were all addressed and abated by February 25, 2003. These violations included issues with combustible storage, missing fire extinguishers, smoke detectors, and door closers.

The building underwent a routine housing inspection in 2010 that was resolved without any reported violations. More recent history shows some resident/visitor parking issues between 2019-2020, with multiple complaints about driveway blocking, and one sewer-related incident in 2013 involving a 4-inch sewer vent backup that was promptly addressed and resolved by PUC Sewer Operations. While the building has had various issues in its past, it appears that all documented violations have been resolved, with no active violations currently on record.
