455 33rd Ave, San Francisco, CA 94121

The two-unit residential building at 455 33rd Avenue in the Outer Richmond, constructed in 1925 and currently owned by the Mafalda Flaviani Living Trust, has undergone several notable maintenance and infrastructure updates, most significantly in January 2014 when the property underwent work to repair and replace cast iron sewer lines as well as sidewalk modifications, which were properly completed under the relevant plumbing permit.

The building experienced two incidents of non-offensive graffiti in September 2016, though these were administratively closed by the Department of Public Works. The property has seen recurring issues with street cleanliness over the years, with multiple reports of loose garbage along the street and sidewalk in 2010, 2017, and 2018, all of which were resolved by the DPW.

The most recent incident related to the property was in October 2021, involving a parking enforcement issue with a driver's vehicle blocking a driveway, which resulted in a citation. The building's maintenance history suggests regular attention to infrastructure needs, particularly regarding sewer line maintenance, while the street cleaning incidents appear to be neighborhood-wide issues rather than property-specific problems.
