Hartford, Conn., Mun. Code ch. 18 § 18-102

A. Notwithstanding any other provisions of this chapter, whenever the director of licenses and inspections or director of health finds that an emergency exists which requires immediate action to protect the public health or safety, he or she may, without notice or hearing, issue an order reciting the existence of such an emergency and requiring: immediate remedial action in accordance with section 18-105 of this code, the vacation of the housing for a temporary or permanent period, or any other action he or she deems necessary to meet the emergency, and such order shall be effective immediately.
B. The following are example, non-exclusive, circumstances justifying emergency action pursuant to this chapter for any housing regulated by this chapter:
(1) The operation of any illegal or unpermitted primary or accessory use (including but not limited to a drinking place, eating place, entertainment assembly, private club, smoking place, or tattoo/piercing parlor as such uses are defined in the zoning regulations) on the premises.
(2) Prima facie evidence of illegal activities being conducted on the premises, which are not being remedied by the owner. In such instances, the Director of Licenses and Inspections may order an appropriate action against the owner, but may not bypass the provisions of G.S. §§ 47a-23 et seq.
(3) A noncompliance with an applicable life safety code which poses an immediate threat to health, safety, or welfare, including noncompliance resulting from an accident, such as a fire, or unexpected Act of God.
(4) An infestation that renders the premises unfit for human habitation.
C. Any person to whom such order is directed shall comply therewith immediately but, upon petition to the director of licenses and inspections or director of health, as applicable, shall be afforded a hearing as soon as possible, in accordance with article X of this chapter.
