(a) Any town, city or borough or any interested person may propose amendments to the State Building Code, which proposed amendments may be either applicable to all municipalities or, where it is alleged and established that conditions exist within a municipality which are not generally found within other municipalities, any such amendment may be restricted in application to such municipality. Each amendment to the State Building Code shall be adopted in accordance with the provisions of § 29-252b.

(b) The State Building Inspector may grant variations or exemptions from, or approve equivalent or alternate compliance with, the State Building Code where strict compliance with the code would entail practical difficulty or unnecessary hardship, or is otherwise adjudged unwarranted, provided the intent of the law shall be observed and public welfare and safety be assured. Any application for a variation or exemption or equivalent or alternate compliance received by a local building official shall be forwarded to the State Building Inspector by first class mail not later than fifteen business days after receipt by such local building official and shall be accompanied by a letter from such local building official that shall include comments on the merits of the application. Any such determination by the State Building Inspector shall be in writing. Any person aggrieved by any decision of the State Building Inspector may appeal to the Codes and Standards Committee not later than thirty days after mailing of the decision. Any person aggrieved by any ruling of the Codes and Standards Committee may appeal to the superior court for the judicial district wherein the premises concerned are located.
