The Council may in a single ordinance, adopt or amend by reference provisions of a standard published code of regulations. The regular ordinance procedure applies except that neither the code of regulations nor its amendments need be distributed to the public or read in full at the hearings. For a period of 15 days before adoption of the regulations at least five copies of the code of regulations must be made available for public inspection at a time and place set out in the hearing notice. Only the adopting ordinance need be printed after adoption. The Council may sell the adopted code to the public.
