5164-5170 3rd St, San Francisco, CA 94124

The 6-unit, 2-story multi-family residential building at 5164-5170 3rd Street in Bayview, owned by Mazzei Family Trust, was constructed in 1914 and has experienced several maintenance and infrastructure issues over its history. The most recent incident involved a sewage backup discharge from the side sewer vent in July 2024, with another similar issue reported in November 2021. In 2023, there were complaints about tree roots damaging the sidewalk and reports of waste on the street.

The building faced significant maintenance challenges in 2005, when multiple violations were documented including problems with ceilings, flooring, plumbing fixtures, and concerns about lead-based paint, all of which were abated by September 2005. Subsequent issues were noted in 2009 with utilities including a malfunctioning sink, oven, and electrical outlet. The building underwent some exterior improvements in 2006 with the installation of a new awning and signage valued at $2,600, and a street space permit was issued in 2014.

The property has been the subject of several routine inspections over the years, with the most recent inspection records showing ongoing concerns with the sewer system. Two historical records note the presence of G. Mazzei & Son Hardware, which was recognized under the Legacy Business Registry. The building's maintenance history suggests ongoing challenges with basic infrastructure systems, particularly plumbing, while more recent records indicate external maintenance issues such as tree root damage and sidewalk maintenance needs.
