557 Vermont St, San Francisco, CA 94107

The three-story, two-unit multi-family residential building at 557 Vermont Street in Potrero Hill is a 1907 flats and duplex structure currently owned by Bethany Brodsky-Porges. The property has undergone several significant improvements over the past two decades, with the most recent major upgrades including the installation of solar panels (2016), a battery storage system (2017), and comprehensive bathroom renovations in 2015 that included both remodeling existing spaces and adding new facilities on the third floor.

The building has received important infrastructure upgrades, including new electrical service (200 amps with two meters) in 2015 and window replacements in 2015, which involved installing energy-efficient double-glazed windows throughout the property. The building's maintenance history shows attention to structural integrity and safety, with completed projects including foundation replacement (2003), wood stair repairs (2004), and roofing work (1999). While there were some compliance issues in 2003 regarding unpermitted work on front stairs and landing, these violations were eventually resolved by March 2005.

Recent 311 calls related to the property primarily concern external matters such as sidewalk conditions, street cleaning, and parking issues, rather than building-specific concerns. Notably, there are currently two open reports from 2021 regarding collapsed sidewalk conditions that may warrant attention. The property's most recent building permit activity was recorded in 2015, with no major structural changes or building code violations reported in the past eight years, suggesting regular maintenance and compliance with city regulations.
