In 2005, the building faced multiple violations related to lead paint hazards, stairs, and alarm system issues, though these were abated by April 2005.

There were also several complaints about the building's combined sewer system with the adjacent restaurant, particularly regarding clogs and leakage issues, with the most recent complaints in 2022. The property underwent substantial renovations in the late 2000s, including kitchen hood upgrades in 2009 to meet UL 300 standards.
