475-477 28th Ave, San Francisco, CA 94121

The two-unit residential building at 475-477 28th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1917, currently owned by the Kwong Jenny Y K Trust. The property's maintenance record shows relatively few significant interventions over its history, with the only documented building permit being for a re-roofing project completed in 1989, which is typical for structures of this age.

Recent activity records from the past 15 years primarily consist of parking-related issues, particularly in the vicinity of the property, with multiple reports of sidewalk parking between 2018 and 2020, though most of these cases were resolved through official intervention. Street cleaning matters were documented in 2009 and 2012, representing general maintenance concerns rather than specific building issues.

Of particular note was a December 2011 environmental health intervention that was transferred to the Healthy Housing & Vector Control Program, though the specific nature and resolution of this incident are not detailed in the available records. While the building's documented history shows routine urban maintenance issues, there are no recorded incidents directly impacting building safety or resident experience in recent years.
