490-492 Pennsylvania Ave, San Francisco, CA 94107

The two-unit residential building at 490-492 Pennsylvania Avenue in Potrero Hill, owned by Kim Angela K & Anthony S, is a two-story flats and duplex structure built in 1963. The property has undergone several significant renovations, most notably in 2009 when both units received comprehensive upgrades including kitchen and bathroom remodels, window replacements, electrical system upgrades (from fuses to breakers), and new appliance installations, with work valued at $50,000. This was followed in 2011 by additional window improvements, replacing wood windows with energy-efficient vinyl frames.

Earlier structural maintenance includes a 2001 deck beam and post replacement. The building's infrastructure was further enhanced in 2009 with plumbing upgrades including new sinks, dishwashers, and washer/dryer installations in both units, though this permit has since expired. The property has experienced recent maintenance challenges, with multiple 311 calls in late 2024 regarding graffiti (both offensive and non-offensive), sidewalk cleaning issues, and abandoned furniture.

Notably, there have been three reports of garbage and debris removal needed between November 20-27, 2024, including one instance involving furniture. Three graffiti incidents were reported between September 2024 and December 2024, with one case requiring service from the Street Environmental Services Graffiti Crew. While these recent issues suggest some external maintenance challenges in the vicinity of the building, they do not necessarily reflect conditions within the units themselves. A historical tenant buyout was recorded at 506 Pennsylvania Avenue in November 2017 for $20,000 involving one tenant, though this is for a different property.
