The building's infrastructure has been consistently maintained, with records showing previous roof deck repairs in 2004 due to decay, complete rewiring in 2003, and the installation of an electric car meter in 2018.

Recent maintenance and service requests have been limited, with the most recent service request made in February 2024. The building's maintenance history suggests regular upkeep, with major systems such as electrical and plumbing receiving appropriate attention over the years, including the installation of modern amenities like an electric car charging system, while preserving the structure's historical character through thoughtful rehabilitation projects.
