Plumbing updates have been consistent, with the most recent work including sink and water heater relocations in 2021, following earlier comprehensive plumbing upgrades in 2014. The property has experienced typical urban issues as evidenced by 311 calls, mostly related to street-level concerns such as parking violations and sidewalk cleaning, though none directly related to building safety or maintenance.
