The building has documented multiple fire safety concerns, with violation notices issued regularly between 2016 and 2024 for various issues including alarm system maintenance, multiple fire code violations, and decorative materials concerns. The most recent fire code violations were issued in October 2024, and while some previous violations have been abated, the pattern of recurring violations suggests ongoing fire safety compliance challenges.

The property has also experienced infrastructure upgrades, including plumbing work in 2018 for system improvements, and electrical system upgrades including a 200-amp service installation. Historical records indicate past concerns about illegal attic space and basement bathroom usage, though these complaints are no longer active.

Recent 311 calls from 2023-2024 have primarily related to external issues such as sidewalk graffiti, parking violations, and street cleaning matters, rather than building-specific problems.
