593 Pennsylvania Ave, San Francisco, CA 94107

The property at 593 Pennsylvania Avenue in Potrero Hill is a century-old, one-story multi-family residential building containing three units, currently owned by Peter Kai Ming Chen. The building's maintenance history shows several significant infrastructure updates, with the most recent being a complete side sewer replacement in October 2023, which followed the discovery of disintegrated components during work on the new sewer lateral.

In 2015, interior repairs were undertaken to address dry rot, including the removal and replacement of approximately 100 square feet of drywall and tile, while earlier structural improvements included window upgrades in 1989 (installation of six aluminum windows) and major work in 1984 involving roof replacement and front wall construction. The building has faced some administrative scrutiny, evidenced by a complaint in 2005 regarding possible illegal units and concerns about property encroachment, though this case was closed within a month.

More recently, between 2017 and 2022, there were multiple municipal service calls related to urban maintenance issues, primarily concerning street cleaning, tree maintenance, and waste removal in the vicinity of the property. Notable among these was the emergence of tree root-related sidewalk damage (report dated May 2022) and several instances of human or animal waste reported on or near the property's private pathways in August 2019. The most recent tree maintenance requests from 2017 indicate ongoing attention to the building's immediate environment, though many of these exterior issues have been handled by city services rather than direct building management intervention.
