Hartford, Conn., Mun. Code ch. 18 § 18-103

A. The director of licenses and inspections may, in his or her discretion, postpone the last day by which a violation shall be corrected upon a showing by the owner or other responsible person that he or she has begun to correct the violation, but that full correction of the violation cannot be completed within the time provided because of technical difficulties, inability to obtain necessary materials or labor, or inability to gain access to the dwelling unit wherein the violation exists, provided that such postponement shall not exceed sixty (60) days from the date by which corrections would be made pursuant to the original notice, unless the affected party seeks an additional extension pursuant to article X of this chapter.
B. When the violation has been corrected, the responsible party shall promptly, but not later than two (2) weeks after such correction, report to the director of licenses and inspections in writing, indicating the date when each violation was corrected. It shall be presumed that the violation was corrected on the date so indicated, unless a subsequent inspection by the director of licenses and inspections reveals the existence of the condition giving rise to the earlier notice of violation.
C. If the person who is sent notice pursuant to section 18-100 wishes to admit liability for any alleged violation, he may, without requesting a hearing, pay the full amount of the fines, penalties, costs, or fees admitted to in person or by mail to the city.
D. Any person who does not deliver or mail written demand for a hearing within ten (10) days of the date of the first notice of violation shall be deemed to have admitted liability, and the corporation counsel shall certify such person's failure to respond.
