588-592 Pennsylvania Ave, San Francisco, CA 94107

The three-unit multi-family residential building at 588-592 Pennsylvania Avenue in Potrero Hill, owned by Bennet Charles E & Eisen Jo, has undergone several significant upgrades and maintenance work since its construction in 1900. Most recently, in 2024, the property has seen improvements in energy efficiency with the installation of heat pump water heaters, including two separate permits in January and October 2024, as well as the addition of a ductless mini-split system in May 2023. Structural improvements have been substantial, including the replacement of rear entry doors (2024), windows (2017), back stairs to the third floor (2014), and a roofing project in 2011.

The building faced some safety-related issues in October 2015 during a routine safety inspection, when violations were recorded regarding fire extinguisher servicing and carbon monoxide alarm installation, though these were promptly resolved by November 2015. The property has experienced recurring sewer issues, with multiple incidents reported between 2014-2019, including sewage backups and water leak problems, suggesting ongoing infrastructure challenges in this area. A notable water infrastructure upgrade was completed in 2009 with the replacement and installation of a house trap.

Recent improvements indicate active maintenance of building systems, particularly in terms of energy efficiency upgrades and structural maintenance. There were no fire incidents directly involving the building, though a vehicle accident cleanup was noted in the vicinity with no civilian injuries reported. The building's maintenance history shows regular upkeep, though the frequency of sewage-related issues indicates this remains an area requiring attention.
