Ordinances shall not be passed within five days of their introduction, nor at other than a regular meeting or at an adjourned regular meeting. However, an urgency ordinance may be passed immediately upon introduction and either at a regular or special meeting. Except when, after reading the title, further reading is waived by regular motion adopted by majority vote, all ordinances shall be read in full either at the time of introduction or passage. When ordinances, other than urgency ordinances, are altered after introduction, they shall be passed only at a regular or at an adjourned regular meeting held at least five days after alteration. Corrections of typographical or clerical errors are not alterations within the meaning of this section. This section shall not apply to ordinances which by statute can be passed only after notice and a public hearing.
