Full Breakdown
D provides otherwise. 5 Zone, 25-foot front with just 8 feet on the side and rear lines. A footnote raises the side and rear setback in the four smaller zones to a flat 25 feet whenever the use is a non-residential use permitted by Special Permit in a residential zone. A second footnote governs the Special District R-20 Zone specifically: its minimum front yard setback is 40 feet from the recorded right-of-way of Main Street, but only 25 feet from any other front lot line or right-of-way, recognizing the tighter build-to line historically used along Main Street.
6 lists separate dimensional exceptions, and commercial and business-zone yards are set elsewhere in the Regulations. Any construction that does not meet the applicable table figure needs either a variance or must be redesigned to conform before the Zoning Enforcement Officer issues a zoning permit.
Violations & Fines
Section 10.1.F of the Regulations makes commencing or maintaining work, a use, or an activity that needs a zoning or special permit before obtaining it, or that fails to conform to the conditions of the permit issued, subject to enforcement action and a penalty under Conn. Gen. Stat. § 8-12. Filing an after-the-fact application does not excuse the violation, and the Zoning Enforcement Officer may add a fee of up to twice the otherwise applicable permit fee on top of any other remedy.
