The property has experienced significant maintenance issues in 2025, with multiple 311 complaints and Housing Maintenance Code violations related to water leaks (both "slow" and "heavy flow"), mold, window frame problems, and paint/plaster concerns. Notably, there are two open violations from October 2024, including an infestation of roaches in apartment 3J and an access issue to the building's heating system.
Earlier complaints from 2025 indicate recurring heat and hot water problems, both in individual apartments and the entire building. The building has been subject to several rodent control efforts in recent months, with inspection reports from 2024-2025 showing "Rat Activity" in January and August 2024, and multiple bait applications in 2025. The property has a history of various code violations and compliance issues, including an environmental control board violation in 2020 regarding obstructed exit passageways, which was resolved.
There were also concerns about illegal conversions and work without permits, though inspections in 2021 and 2025 found no violations at the time. The building's maintenance history shows a pattern of water-related issues, with multiple complaints and violations regarding leaks and moisture problems. While bedbug infestations have been reported in previous years (most notably in 2021), recent filings from 2022-2024 show no current infestations. The most recent permit issuance was for exterior work in 2018, though there has been no indication of significant improvements since then.
