50-52 Cole St, San Francisco, CA 94117

The two-unit multi-family residential building at 50-52 Cole Street in Park North, constructed in 1911 and classified as a Flats & Duplex, is currently under ownership of the John Allan Bier Living Trust. The property has undergone several significant infrastructure improvements in recent years, with the most notable being electrical system upgrades in 2024, including knob and tube rewiring, sub-panel installations, and a main panel upgrade from 60A to 200A.

The building's historical maintenance record shows efforts to bring the structure into compliance with building codes in 1987 and 1990, though permits from these projects are now expired. A reroofing project was initiated in 1994, however this permit also reached expired status.

The property has experienced recurring issues with graffiti, with the most recent incidents occurring in September 2023 on the sidewalk and September 2022 on the building itself, though the 2022 incident was partially attributed to a backlog created by the COVID-19 pandemic's suspension of enforcement on the San Francisco Graffiti Ordinance. Other exterior maintenance concerns have been documented through 311 calls, including missed street cleaning routes in January 2025, an overflowing city garbage can in July 2022, and various street cleaning needs in January 2015. It's worth noting that many of the historical permits required to bring the building into code were issued in the late 1980s and early 1990s, suggesting that the current electrical upgrades in 2024 are addressing an older wiring system that was last worked on over 30 years ago.
