Council may, by reference to the date and source, and without reproducing it at length in the ordinance, adopt model or standard codes prepared and published by public or private agencies on such matters as fire prevention, building construction, electrical wiring, plumbing, heating, ventilating, air conditioning, and other similar matters. However, if Council desires to modify, add to, or eliminate from any such code and section or part thereof, such addition, modification, or omission shall be clearly stated in the ordinance, together with a cross reference to its location in the code. In all cases in which such a code shall be adopted by reference, publication by the Municipality of the code in its entirety shall not be required. However, at least one copy of each such code shall be kept in the office of the Manager for examination by interested persons during regular office hours. In the enacting ordinance Council may also provide that any amendments to the incorporated code by the promulgating agency shall also, without further action by Council, be deemed an amendment to the enacting ordinance.
