WATERTOWN â Youâll have to wait a little longer to get into City Hall without making an appointment. While the Washington Street building is open to the public, access to City Hall offices remains only by appointment. City Manager Kenneth A. Mix said lingering security concerns are the reason why the public cannot enter City Hall without scheduling it in advance. Initially, City Hall was closed to the public because of the pandemic but the building has been open for about a year through appointments. It will remain that way until city officials make some long-term decisions on how to handle security, Mr. Mix said.
