Hartford, Conn., Mun. Code ch. 18 § 18-101

A. If any violation documented in any notice of violation is not remedied within the specified time period, the owner shall be issued a citation.
B. Such citation shall:
(1) Be put in writing.
(2) Include a statement of the reasons why it is being issued, including appropriate code citation.
(3) Be served upon the owner or the occupant, as the case may require; provided, that such citation 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 by any other method authorized or required by the laws of this state; and, if an email address has been provided, an electronic copy of a citation may be sent to the alleged violator, provided that failure to send such a copy shall not be considered a failure to serve.
(4) State the fines, penalties, costs, or fees due, or action required to be taken.
(5) State that the recipient may contest his or her liability before a hearing officer in person or by mailed written notice within ten (10) days of the date thereof, and that if he or she does not demand such a hearing, an assessment shall be entered against him or her, and that such assessment may issue without further notice.
C. The owner shall be presumed to shall bear primary responsibility for violations of this chapter that arise from obligations of the owner: however, operators or occupants may be jointly or severally liable depending on the factual circumstances.
