1221 Potrero Ave, San Francisco, CA 94110

The property at 1221 Potrero Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood. Built in 1908 and owned by German R. and Blanca L.

Moncada, this flats and duplex-style building has a documented history of various maintenance and safety-related issues. The most significant historical event was a fire incident in 1995, after which permits from 1991-1994 show work related to fire safety, including the installation of a fire wall between units. The building has undergone several important repairs and upgrades in recent years, including electrical system improvements in 2013 (replacement of plastic junction boxes with metal, main panel upgrade) and structural maintenance in 2018 (repair of non-visible rear stairs and landing).

Recent concerns have primarily centered around maintenance and environmental issues, with an ongoing pattern of graffiti incidents recorded between 2023-2024, affecting the building, sidewalk, and nearby street areas. While most previous structural concerns were addressed promptly, as evidenced by completed permits for roof shingle replacement (2012) and rear stair repairs (2018), an unresolved back door security issue, rotting back stairs, loose floorboards, and inoperable windows were documented in a 1999 housing complaint, though these issues were marked as abated shortly thereafter. The building's electrical system has been modernized, with permits showing significant upgrades to accommodate new systems, and while recent 311 calls primarily relate to external graffiti issues, there have been some utility maintenance matters such as a burnt-out street light that was promptly repaired in 2024.
