Section 27.   MODE OF ENACTMENT.
   (1)   Except as this section provides to the contrary, every ordinance of the council shall, before being put upon its final passage, be read fully and distinctly in open council meeting on two different days.
   (2)   Except as this section provides to the contrary, an ordinance may be enacted at a single meeting of the council by unanimous vote of all council members present, upon being read first in full and then by title.
   (3)   Any of the readings may be by title only, (a) if no council member present at the meeting requests to have the ordinance read in full or (b) if a copy of the ordinance is provided for each council member and three copies are provided for public inspection in the office of the city recorder not later than one week before the first reading of the ordinance and notice of their availability is given forthwith upon the filing, by (i) written notice posted at the city hall and at two other public places in the city or (ii) by advertisement in a newspaper of general circulation in the city. An ordinance enacted after being read by title alone may have no legal effect if it differs substantially from its terms as it was thus filed prior to such reading, unless each section incorporating, such a difference is read fully and distinctly in open council meeting as finally amended prior to being approved by the council.
   (4)   Upon the final vote on an ordinance, the ayes and nays of the members shall be taken and recorded in the journal.
   (5) Upon the enactment of an ordinance the recorder shall sign it with the date of its passage and the name and title of office, and within three days thereafter the mayor shall sign it with the date of signing, the mayor’s name and title of office.
