451-453 28th Ave, San Francisco, CA 94121

The two-unit residential building at 451-453 28th Avenue in San Francisco's Central Richmond neighborhood is a two-story, flats and duplex structure built in 1919, currently owned by Lee Shuey & Dip Fay Yee Tru.

The building's documented history reveals a significant cluster of plumbing and sewer-related issues in late 2016, with four distinct reports of water leaks and a sewage backup incident involving a 4-inch sewer vent on November 30, 2016, that required direct intervention from PUC Sewer Operations and was marked as resolved. The property has generally been quiet in terms of incidents since then, with only two parking-related complaints recorded in recent years - one in 2023 involving a black Dodge vehicle blocking a driveway, which was resolved, and another in 2018 where officers were unable to locate the offending vehicle.

The only building permit on record dates back to 1994 for roofing work, though this permit has since expired. The building's recent history suggests minimal major maintenance or incident patterns, with the most significant historical concerns being water and sewer-related rather than structural or safety issues.
