After the hearing, the legislative body may amend, adopt or reject the adopting ordinance in the same manner in which it is empowered to act in the case of other ordinances; and, except as to the adoption of a code of existing ordinances of the adopting agency, nothing in this article shall be deemed to permit the adoption by reference of any penalty clauses which may appear in any code which is adopted by reference. Any such penalty clauses may be enacted only if set forth in full, and published, in the adopting ordinance. It is further provided that all changes or additions to any code made by the legislative body shall be published in the manner which is required for ordinances.
