A lot in any zone existing as of December 14, 1963, having sole access to a street by means of an easement, right of way or strip of land, and a lot having frontage only on a private road or trail shown on a subdivision plan filed in the Newtown Town Clerk's Office which is not valid under the Newtown Land Subdivision Regulations effective October 2, 1967, may be used for uses permitted in the zone and permitted buildings erected, altered or enlarged thereon provided that said easement, right of way, strip of land, private road or trail is at least 12 feet wide and will permit unlimited access for owners of such lot and for all public utilities.
(1) Lots other than those having frontage on such a private road or trail may be so used and the permitted buildings erected, altered or enlarged only if the lot has not been owned or controlled by a person or persons owning or controlling any other means of access to a street or a wider easement, right of way or strip of land at any time subsequent to December 14, 1963. If said lot cannot meet the area or minimum square requirements for the zone in which it lies it may still be used provided that it has not been reduced in area at any time subsequent to December 14, 1963, and did not and has not since said date adjoined other improved or unimproved land owned or controlled by the same person owning or controlling said lot.
(2) The same requirements set forth in Subsection
1 hereof shall apply to lots having frontage only on such private roads or trails.
(3) Said lots shall conform in all other respects to the provisions of these Regulations.
