1121 Potrero Ave, San Francisco, CA 94110

The two-unit residential building at 1121 Potrero Ave in San Francisco's Inner Mission district, owned by the Ross Trust, is a two-story flats and duplex structure built in 1909. The property has undergone several significant maintenance and improvement projects over the past few decades, with the most recent notable work being a $10,000 reroofing project completed in 2022, and electrical panel upgrade in 2019. The building has seen substantial modernization efforts, particularly in 2010 when the kitchen was extensively renovated with new cabinets, countertops, appliances, and plumbing fixtures, though this work initially triggered two complaints regarding unpermitted modifications and wiring, which were later addressed and abated.

The property has a documented history of maintenance work including bathroom renovations (1992), rear stairs reconstruction (1990), and an earlier reroofing project (1989). More recently, between 2024 and 2023, there have been multiple incidents of graffiti reported in and around the property, particularly affecting the building's exterior and surrounding public infrastructure, with eight incidents recorded by 311 calls between August 2024 and December 2024. Most of these cases were resolved by city services, though some were marked as duplicate requests.

The building's maintenance history shows regular upkeep, with records of street space permits issued in 2014 and 2019, and various electrical and plumbing improvements. A single smoke incident was recorded, but no civilian injuries were reported. The property's documented history suggests ongoing maintenance and upgrading of systems, with particular attention to roofing, electrical infrastructure, and interior spaces, while the recent concentration of graffiti incidents represents the most significant current concern regarding the property's immediate environment.
