280 Pennsylvania Ave, San Francisco, CA 94107

The 4-unit multi-family residential building at 280 Pennsylvania Avenue in Potrero Hill is a 2-story apartment structure built in 1912, currently owned by Vincent P & Maria Elena Ali. The property has undergone several significant infrastructure improvements over the past two decades, with the most recent major work being reroofing completed in 2020 at a cost of $17,375.

Other notable upgrades include the replacement of the main water pipe in 2016, refurbishment of the rear exterior stairs in 2009, and a substantial electrical system upgrade in 2012 that included installing a new 200-amp service with individual metering for each unit. The building has been subject to regular housing inspections, with routine health and safety inspections recorded in 1999 and 2009, though neither inspection appears to have resulted in ongoing concerns.

More recently, during December 2024, there have been multiple reports of street-related issues in the vicinity of the building, including several complaints about encampments and instances of garbage and debris that were reported through the city's 311 system. While these external environment concerns have been consistently resolved by city services, they represent a notable pattern of neighborhood maintenance challenges in the immediate vicinity. The building's maintenance record shows regular attention to its infrastructure needs, with no documented building code violations or safety concerns directly related to the structure itself over the past two decades.
