Lot Width. On regularly shaped lots, the minimum lot width of any lot shall be measured at the front property line and minimum front yard setback line as required for the zone in which it is located and shall be maintained for a distance of 40 feet to the rear of the required setback line. In cases of lots fronting on culs-de-sac, which are turnarounds at the end of streets with a single ingress and egress, the lot frontage measured at the street right-of-way line shall not be less than 50% of the required minimum lot width or 75 feet, whichever is greater.

Corner Lots. At all street intersections, no obstruction to vision exceeding 30 inches in height above the established grade of the street at the property line shall be erected or maintained on any lot within the area bounded by the line drawn between points along such street lot line or their extension thereof 30 feet distant from their intersection. Every yard of a corner lot which abuts a street shall be considered a front yard. The front yard setback requirements specified in § 17-29, Schedule 1, Area, Yard and Bulk Requirements, shall be complied with on every street frontage. The width requirements for corner lots specified in § 17-29, Schedule 1, Area, Yard and Bulk Requirements shall be the minimum lot width along the street the principal building faces; the minimum lot width along the other street shall comply with the Schedule 1 requirements for interior lots. The only exception to the width requirements of a corner lot shall be in the B-1 Business Zone, where the side yard shall be 1/2 of the corner front yard setback.

Yards of Lots Fronting on More Than One Street, Other Than Corner Lots. Where a lot which is not a corner lot fronts on more than one street, every yard which abuts a street shall be considered a front yard, and the front yard setback requirements for the zone in which the lot is situated shall be complied with on every street frontage. In the case of a lot running through from one street to another, the frontage of such lot, for the purposes of this Article, shall be considered that frontage upon which the majority of the buildings in the same block front, but in case there has been no clearly defined frontage established, the owner may, when applying for a building permit, specify on his permit application which lot line shall be considered the front lot line.

Required Area of Space Cannot Be Reduced. The area or dimension of any lot, yard, parking area or other space shall not be reduced to less than the minimum required by this Article; and, if already existing as less than the minimum required by this Article, said area or dimension may be continued and shall not be further reduced.

Frontage Upon a Street. Every principal building shall be built upon a lot with the minimum required frontage on an improved and approved street in accordance with the street standards established by the Borough of Mount Arlington.
