Where the street or private road upon which the lot abuts is less than 20 feet in width, the front yard depth and the width of the side yard abutting the street or private road shall be measured from a line parallel to and 25 feet from the center line of the street or private road. An exception may be made in those cases identified in § 475-11B below where adjacent improved properties affect the setback requirement.

When an unimproved lot is situated between two improved lots, each having a principal building which extends into the required front yard and has been so maintained since the effective date of this chapter, the front yard of such unimproved lot may be the same depth of the front yards of such two adjacent improved lots, notwithstanding the yard requirements of the district in which it is located.

Where an unimproved lot adjoins only one improved lot having thereon a principal building, within 25 feet of the common side lot line, which extends into the required front yard of such improved lot and which extension existed at the effective date of this chapter, the front yard depth of such unimproved lot may be the average depth of the front yard of such adjacent improved lot and the front yard required for the district in which such unimproved lot is located, notwithstanding the yard requirements for such district. However, the second unimproved lot from the original improved lot must have at least the minimum front yard depth required in the district unless it also abuts on an improved lot, as of the time of this chapter, that extends into the required front yard.

Cornices, eaves, gutters, bay windows, and chimneys may not project into the front, side or rear yard of a lot more than 24 inches.

Covered porches, whether enclosed or unenclosed, shall be considered as part of the main building and shall not project into any yard. Except that a screened porch may be erected in the side yard of a nonconforming lot, provided that it shall not be less than five feet from the side lot line.

Uncovered patios, driveways, walks, parking areas, stairs, and window wells, and such other similar structures customarily supplementary to the main building may project into front, side, or rear yards of a lot providing the height shall be not more than 12 inches above the yard grade.

Uncovered steps and entrance canopies not greater than four feet in depth and eight feet in width may project into the required front and rear yard.

Exterior access ramps not otherwise permissible under this subsection may be permitted within any yard upon review and approval of the Montgomery Borough Council.

No fence or wall exceeding six feet in height shall be erected within any of the yards required by this chapter, except in the Commercial and Industrial Districts where security fences may be up to eight feet in height, and except as provided in § 475-11F.

Fences or walls not exceeding six feet in height may be permitted to be located within any of the required yards, but shall be set back at least two feet from all property lines and from the edge of any adjoining street, road, alley or right-of-way. Where, however, there is mutual written consent between the adjoining property owners, a fence or wall may be placed on a property line. A copy of such mutual consent, along with arrangements for maintenance of the fence or wall, shall be submitted to the Zoning Officer along with the application for placement of the structure.

Fences having only one finished side shall be installed so that the finished side faces out or away from the subject property.

All fences and walls shall be maintained in good condition and shall not be allowed to become dilapidated.

No walk, fence, sign or other structure shall be erected or altered and no hedge, trees, shrubs, or other growth shall be maintained or permitted which may cause danger to traffic on a street or road (whether public or private) by obscuring the view.

At all intersections of streets, private roads and/or access drives, a clear sight triangle shall be maintained.

In the case of commercial or industrial uses, this shall not prohibit the erection of signs, provided that the signs are in compliance with the sign section of this chapter.

The clear sight triangle shall be as follows when measured from the point of intersection of:

If not in an enclosed structure, the vehicle or equipment shall be completely screened from view from the adjoining properties and the street at all seasons of the year.

In all other districts, commercial vehicle, truck, tractor, trailer, recreational vehicle, boat, or any similar vehicle or equipment may be stored on the property, subject to the following regulations:
