More recent complaints include plumbing system leaks in 2013, a malfunctioning back door in 2012 that affected emergency egress, and outdated bathroom fixtures. Several building violations were recorded in 2011, primarily related to fire safety concerns in the garage, including the need for fire sprinkler protection and repairs to the garage ceiling with fire-resistant materials.
