A.
The lot or yard requirements for any new building
or use shall not include any part of a lot that is required by any
other building or use to comply with the requirements of this chapter.
B.
No required lot or area shall include any property,
the ownership of which has been transferred subsequent to the effective
date of this chapter, if such property was a part of the area required
for compliance with the dimensional requirements applicable to the
lot from which such transfer was made.
A.
The provisions of this article III shall not prevent the construction of a single-family dwelling in a residential district on any lot that was lawful when created and which, prior to the effective date of this chapter, was in separate ownership duly recorded by plan or deed, provided that:
(1)
Such a lot was lawful when recorded.
(2)
Those lots not served by a public water supply shall
meet all requirements of the Department of Environmental Resources
(DER). Those lots not served by a public sewer shall meet the requirements
of the DER as specified by the Allegheny County Health Department.
B.
This exception shall not apply to any two or more
contiguous lots in a single ownership as of or subsequent to the effective
date of this chapter, in any case where a reparceling or replatting
could create one or more lots which would conform to the chapter.
In all districts, no structure, fence, planting
or other obstruction shall be maintained between ground level and
a plane 10 feet above curb level. This shall be maintained in order
to provide traffic visibility across the corner within that part of
the required front or aide yard which is within a triangle bounded
by the two street lines and a straight line drawn between points on
each such line 75 feet from the intersection of said lines or extension
thereof. When one or both streets which form the intersection are
classified as collector streets or arterial streets, the sight triangle
bounded by the two street lines and a straight line drawn between
points on such line shall be 100 feet or 125 feet, respectively, from
the intersection of said lines or extension thereof.
Where a minimum depth of front yards is specified in §§ 165-25 through 165-31 an open space of at least the specified depth shall be provided between the street line or lines and the nearest point of any building or structure, except as may be permitted hereafter. As provided in § 165-5C, street lines are considered to be established by future rights-of-way when so designated. The purpose of this provision is to avoid interference with future road widenings and improvements.
If the alignment of existing buildings on either
side of a lot, within a distance of 50 feet of the proposed building
and fronting on the same side of the same street in the same block,
is nearer to the street than the required front yard depth, the average
of such existing alignment within that distance shall be the required
front yard.
Projections shall not occur in front yards.

A.
Accessory
buildings and structures shall not be permitted within the required
minimum front yards for principal buildings. Also, accessory buildings
and structures shall not extend in front of the principal building
except as hereafter allowed. If the principal building is set back
more than double the distance required for the minimum front yard
setback, an accessory building may be located in front of the principal
building, subject to obtaining a conditional use approval from the
Borough Council.
B.
Driveway
gates and gateway posts are permitted in front yards so long as the
posts are set back a minimum of 30 feet from the edge of the cartway
or road curb. Additionally, driveway posts and gates shall be designed
to provide a minimum of clear unobstructed opening of no less than
168 inches. An accessory use building permit shall be obtained from
the Code Enforcement Officer prior to the installation of driveway
gates or gateway posts.
Bays, balconies, chimney flues and fire escapes
may project into a required side yard not more than 1/3 of the width
of the projection, but no more than four feet in any case. Ground-story
bays and porches not over half the length of the side wall may project
into any required side yard 3 1/2 feet. In neither instance may
the projection be within 3 1/2 feet of the lot line of side yards.
[Amended 6-14-2021 by Ord. No. 306]
The provisions of § 165-43 shall not apply to terraces, steps, uncovered porches or other similar features less than three feet above the floor of the ground story.

structures shall not be permitted within the required minimum side
yards.
[Amended 11-11-2002 by Ord. No. 226; 6-14-2021 by Ord. No. 306]
Such projections into side yards as permitted by § 165-43 may also be permitted into rear yards, up to the same number of feet, but in no case within five feet of an accessory building. The provisions of this section shall not apply to terraces, steps, uncovered porches, uncovered decks, or similar features less than three feet above the floor of the ground story.
Subject to the provisions of § 165-46, completely detached accessory buildings and structures may occupy a required rear yard but shall not be located closer than 15 feet to any rear lot line.
Residential use requirements shall be as provided
in the Table of Residential Use Requirements found at the end of this
chapter.

provided in the Table of Nonresidential Use Requirements found at
the end of this chapter.
When authorized as a variance in accordance with the provisions of § 165-200, structures such as television and radio towers, monuments, tanks, water and fire towers, ornamental towers and spires, chimneys, silos, elevator bulkheads, conveyers and flagpoles may exceed the height regulation herein prescribed, provided that the required front, side and rear yards are each increased by one foot for each foot of additional height above 35 feet and that the height of such structures will not constitute a hazard. The Allegheny County Airport Zoning Committee must be consulted and a permit secured.
Nonresidential use front yard setback and buffer
requirements shall be as provided in the Table of Nonresidential Use
Front Yard Setback and Buffer Requirements found at the end of this

for good cause, such as containment of a construction area or other
hazard, for a period of no longer than 60 additional calendar days,
or the duration of the construction or other activities, whichever
is shorter. An extension may be granted, at the discretion of the
Borough Zoning Officer, not to exceed 180 total calendar days.

Temporary fencing in place longer than 60 calendar days, without
an approved temporary fencing permit, or left in place following the
expiration of any granted extension, will be considered permanent
and will require zoning approval and permitting.
