Editor's Note: The Table of Nonresidential Uses Area and Bulk Requirements is included as an attachment to this chapter.
No part of a yard or other open space about any building, structure
or use, required for the purpose of complying with the provisions
of this article, shall be included as a part of a yard or open space
similarly required for another building, except when specifically
authorized.
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.
Where a minimum lot size is specified, no primary building or
use shall be erected or established on any lot of lesser size than
as specified in Article 500, except as specified in § 212-507.
B.
For any lot in which the width between the side lines of the
lot are less than the width at the building line, only that portion
of the lot in which the width exceeds 50% of the width of the building
line shall be used to compute the minimum lot area.
A.
The provisions of this article 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 Protection (DEP).
Those lots not served by a public sewer shall meet the requirements
of the DEP 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 article.
A.
Where a minimum lot width is specified, no primary building
shall be erected on any part of a lot which has a width less than
that specified in §§ 212-501 and 212-502, except as
specified in § 212-507.
B.
On lots fronting on a cul-de-sac, it is required that the minimum
lot width be measured at the building setback line.
Where a minimum depth of front yards is specified in Article
500, 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 shall be permitted hereafter. As provided
in Article 200, 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 street 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, as defined in Article 200, shall not occur in front
yards.
The provisions of § 212-509 shall not apply to front
fences or walls less than four feet high above the natural grade in
the required front yard nor to terraces, steps, uncovered porches
or unenclosed porches nor to other similar features less than three
feet above the level of the floor of the ground story of the principal
structure.
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
which encroach on a side yard shall not exceed half the length of
the side wall and may project into any required side yard 3 1/2
feet. In neither instance shall the projection be within 3 1/2
feet of the lot line of side yards.
The provisions of § 212-513 shall not apply to fences
or walls less than six feet above the natural grade nor to terraces,
steps, uncovered porches or other similar features less than three
feet above the floor of the ground story of the principal structure.

Editor's Note: Former § 212-516, Accessory buildings
and structures, was repealed 2-15-2017 by Ord. No. 634-2017.
No portion of a principal building or structure shall be built
within the minimum rear yard specified in §§ 212-501
and 212-502, except as permitted in § 212-518.
Such projections into side yards, as permitted by § 212-514,
shall also be permitted into rear yards up to the same number of feet,
but in no case within five feet of an accessory building.
Structures, such as, but not limited to, television and radio
towers, monuments, tanks, water and fire towers, ornamental towers
and spires, chimneys, silos, elevator bulkheads, conveyors and flagpoles,
may exceed the height regulation herein prescribed, provided that
each required front, side and rear yard shall be 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 shall be consulted and a permit secured,
if applicable.
