21 Stanley Avenue is a three-story, three-unit residential building located in Tompkinsville, Staten Island, and owned by Gary Grinberg. Built in 1915, this Class A building has experienced several concerning maintenance issues in recent years. Most notably, in June 2025, the building was inspected by HPD following multiple complaints that documented several violations including water leaks (both slow and heavy flow), mold, plumbing issues with sinks, and ceiling damage - all classified as emergencies or immediate emergencies. The property has also faced persistent structural and safety concerns, with three open violations from 2021-2022 including an unauthorized alteration involving walls in the third-story public hall and safety issues with a scuttle ladder obstructing egress in the same area. Earlier violations from 2022 documented problems with fire escape access and obstructions, resulting in a $3,125 penalty.
The building has a documented history of rodent activity, with inspections in 2018, 2019, 2020, 2022, and most recently in 2022 showing various levels of rat activity. While the bedbug reports from 2021-2024 show no infestations, the property has experienced multiple sanitation challenges including a 2022 DOHMH report of conditions attracting rodents. The most recent maintenance issues reflect ongoing water and mold problems, with violations issued in June 2025 requiring the owner to address the conditions within specified timeframes.
