576-580 Pennsylvania Ave, San Francisco, CA 94107

The two-unit residential building at 576-580 Pennsylvania Avenue in Potrero Hill is a two-story flats and duplex structure built in 1910, currently owned by the Jennifer G Isaacson Revocable Trust. The property's history reveals several notable events, primarily concentrated around the year 2000 when multiple complaints were filed regarding unauthorized use conversion from R-3 residential occupancy to B commercial occupancy. These violations, which raised concerns about unit integrity and zoning compliance, were officially recorded between August and September 2000, with at least one requiring a Notice of Violation.

All related violations and complaints were ultimately abated by the end of September 2000. More recent activity includes a completed renovation project in 2002 involving the removal of loose plaster and sheetrock, installation of insulation in the basement ceiling and walls, and painting work, which cost approximately $3,000. In 2016, a street space permit was issued for the property with a minimal cost of $1.

More recently, there have been two pavement defect reports in 2023, with one remaining unresolved as of April 2023, though this is a municipal infrastructure issue not directly related to the building's condition. The property's fire incident record shows a single alarm activation due to a malfunction, with no civilian injuries reported. The building's documented history suggests that while there were significant occupancy and use-related issues in 2000, these were promptly addressed, and there have been no major building code violations or safety incidents reported in recent years.
