Hartford, Conn., Mun. Code ch. 18 § 18-100

A. Whenever the director of licenses and inspections determines that there are reasonable grounds to believe that there has been a violation of any provision of this chapter or any rule or regulation adopted pursuant thereto, including but not limited to failure to provide adequate housing pursuant to section 18-51 and failure to apply for a required license, before issuing any citation, such director shall give notice of such alleged violation to the person responsible therefor, provided that no notice shall be required in the case of emergency action as provided in section 18-102 of this code.
B. Such notice of violation shall:
(1) Be put in writing.
(2) Include a statement of the reasons why it is being issued, including appropriate code citation.
(3) Allow a reasonable time, not fewer than twenty-one (21) days or more than sixty (60) days for the correction of any alleged violation, except that in the case of a condition, which in the reasonable judgment of the director of licenses and inspections is or in its effect is dangerous or detrimental to life or health, the date specified shall be not more than five (5) days from the date of service of such notice as provided in 100 (B) (4).
(4) Be served upon the owner or the occupant, as the case may require; provided, that such notice shall be deemed to be properly served upon such owner or upon such occupant, if a copy thereof is served upon him or her personally; or if a copy thereof is sent by registered mail to his or her last known address; or if a copy thereof is posted in a conspicuous place in or about the housing or housing unit affected by the notice; or if he or she is served with such notice; or if a copy is sent electronically to his or her email and receipt thereof is acknowledged in return; or by any other method authorized or required by the laws of this state.
(5) State that unless violations cited are corrected within the time period offered, the division of licenses and inspection will issue a citation imposing fines, penalties, costs, and fees due and the license may be denied, suspended, or revoked; in addition to the penalties provided in accordance with the General Statutes of CT in section 7-148(c)(10)(A).
(6) Upon written request, the director of licenses and inspections may grant one or more extensions of time for correction of any alleged violations if deemed reasonable and for good cause.
C. Such notice of violation may contain an outline of remedial action that, if taken, will effect compliance with the provisions of this chapter and with rules and regulations adopted pursuant thereto. For example, in the case of an infestation, an inspector may require an extermination plan and the complete elimination of infestation; and in the case of a safety concern, an inspector may require that the owner, at the owner's expense, install security cameras, hire a police detail, or take other measures to improve safety.
