Augrented Insights Report for 503 12th Street

The 34-unit, 4-story tenement building at 503 12th Street in South Slope, built in 1916 and currently owned by Jakob Worley, has experienced a number of significant maintenance and safety issues in recent years. Most notably, in early 2025, there were multiple complaints regarding unsanitary conditions and pests, with violations issued in May.

The building has also faced recurring heating system problems, with complaints about lack of heat and hot water in March 2025, though inspectors could not gain access to verify the conditions. Previous violations include issues with window guards, door self-closing mechanisms, and various maintenance problems in apartment 2C identified during 2023-2024 inspections. The property has a concerning history of rodent activity, with failed inspections in 2016, 2017, and 2023, though recent inspections in 2024 have passed.

There have been multiple building system violations and maintenance issues documented through 311 complaints and Housing Maintenance Code violations, including problems with the roof, stair threads, and various interior conditions. The building has also undergone several tenant safety inspections in 2025, with some resulting in Oath Violations. While the building has maintained a clean record for bedbugs in recent years, with no reported infestations since 2020, the persistent pattern of heating, pest, and maintenance issues suggests ongoing challenges with building systems and upkeep.
