When any housing commission or housing authority which is created for any state public body becomes authorized to transact business and exercise its powers therein, the governing body of such state public body, shall immediately make an estimate of the amount of money necessary for the administrative expenses and overhead of such housing commission or housing authority during the first year thereafter, and shall appropriate such amount to the housing commission or housing authority out of any moneys in the treasury of such state public body not appropriated to some other purposes.
