(b)(2)(A), effective July 13, 2005.See Secs. 8-28a and 8-28b re guarantee that change in zoning regulations or districts or in subdivision regulations does not affect approved subdivision plan.Subdivision plan must have been formally approved prior to effective date of change in order to be covered by section. 148 C. 299. Cited. 153 C. 194. Not applicable where plaintiffs had filed maps of subdivisions prior to adoption of regulations where subdivision plan had never been approved. 155 C. 185.Cited. 25 CA 85; 35 CA 820.Subsec. (b):Cited. 36 CA 98. Plaintiff's 1954 subdivision plan that included his lot and was approved, filed and recorded in the town placed lot within the scope of Subsec. and gave plaintiff a vested right; any subsequently enacted regulations are not applicable to plaintiff and do not prevent plaintiff from receiving a zoning permit for subsequent improvements that would otherwise violate subsequently enacted regulations. 75 CA 289. Under Subdiv. (2), lot was not required to comply with subsequent changes because lot was vacant and unimproved when building permit was sought. 118 CA 90.
