Every principal building or structure shall be built upon a lot with at least the minimum required frontage upon an improved and approved street.

The minimum lot width shall be measured at the front lot line.

The sketch maps in the appendix illustrate the delineation of yards for measurement purposes regarding corner lots and other lots. The location of driveways, front doors or front facades shall not be relevant in regard to the foregoing regulations.

Within any sight triangle, no grading, vegetation, sign or other object shall be allowed to exceed a height or thirty (30") inches above the adjacent roadway, or be placed in such a manner as to limit or obstruct the sight distance of motorists entering or leaving the intersection. Said triangle shall be formed by the street lines of such lot and a line drawn between points along such street liens twenty-five (25') feet distant from their point of intersection.

Where a single lot under individual ownership extends from one street to another, defined herein as a through lot, both frontages shall be subject to the front yard requirements of this chapter.

In all cases where a lot is divided by one (1) or more district boundary lines, regulations for the less restricted portions of such lot shall not extend into the more restricted portion.
