2509-2515 Harrison St, San Francisco, CA 94110

The property at 2509-2515 Harrison Street is a 4-unit, 2-story multi-family residential building constructed in 1907, currently owned by Ariel Prochowski. The building has undergone several significant maintenance and infrastructure upgrades over the past decades, including recent reroofing work completed in 2022 (cost: $8,000), a 200-amp electrical service upgrade with 5 meters and outdoor lighting installation in 2011, and plumbing work including sewer repair and house trap maintenance in 2008.

A comprehensive set of building violations was documented in October 2003, including issues with exterior stairs, gas meter safety, lighting, security, and fire safety, all of which were resolved by February 2004. Recent concerns include two fire-related violations from 2018 and 2020 regarding fire code compliance and sprinkler systems, both of which were subsequently abated. The property has also experienced some water drainage issues affecting adjacent construction in 2009, though this was resolved quickly.

The building's maintenance history shows regular attention to structural and safety requirements, including a rear stair repair in 2003 and multiple roofing projects in 1992 and 2022. Recent 311 calls from 2024 have primarily concerned exterior maintenance issues such as garbage and debris, along with some parking enforcement matters, though these are more related to the neighborhood's condition than building-specific issues. The latest documented fire safety violation regarding the sprinkler system was issued in 2020 and marked as abated in April 2021, indicating resolution of this particular concern.
