The building's owners cite security as the reason for the continued closure. They have rented the deck for private functions and have expressed intent to replace it with more office space. Boston city officials contend that security concerns are moot, since most similar attractions have long since reopened. In addition, they note that a public observation deck was a requirement for the original building permits to gain public benefit from the high tower. However, officials have not been able to locate the documentation of this requirement.
