(a) When the notice or order of vacation follows a notice or order of abatement, as provided in Section 1333.03, enforcement of such notice or order of vacation shall not be carried out as provided in this chapter unless the notice or order of abatement specifies a time when the person so notified or ordered may appear for a hearing before Council or other appropriate authority to show cause why such order or notice of vacation should not be issued. The hearing shall be set not less than five days after service of the notice or order of abatement.
(b) When the notice or order of vacation is issued as provided in Section 1333.03 without a previous notice or order of abatement, the enforcement of such notice or order of vacation shall not be carried out as provided in this chapter unless it specifies a time, not less than five days after service of the notice, when the person so notified or ordered may appear for a hearing before Council to show cause why such notice or order should not be enforced. In the event of an emergency which requires, for the protection of the health of occupants, the vacation of the building or portion thereof without delay, then no such fixing of a time for a hearing as provided herein shall be required.
