[CC 1983 App. B Art. XIII; Ord. No. 379.5, 5-18-1970]
The required height and area regulations are hereby established and are shown in Section
405.580, and are qualified or supplemented in the text of this Article. The district regulations hereinafter set forth in this Section qualify or supplement, as the case may be, the district regulations appearing elsewhere in this Chapter.
[CC 1983 App. B Art. XIII §1; Ord. No.
379.5, 5-18-1970]
A. Public,
semi-public, or public service buildings, hospitals, institutions
or schools, when permitted in a district may be erected to a height
not exceeding sixty (60) feet if the building is set back from each
yard line at least one (1) foot for each two (2) feet of additional
building height above the height limit otherwise provided in the district
in which the building is located. In designated airport approach and
transition zones, such buildings shall not exceed the height restrictions
of such zones as specified in this Section.
B. Chimneys,
church steeples, cooling towers, elevator bulkheads, fire towers,
monuments, stacks, stage towers, or scenery lofts, tanks, water towers,
ornamental towers, spires, wireless towers, grain elevators or necessary
mechanical appurtenances may be erected to such height as may be authorized
by the City Council, but not to exceed one hundred fifty (150) feet.
In designated airport approach and transition zones, such structures
shall not exceed the height restrictions of such zones as specified
in this Section.
C. The
following special regulations shall apply to any land airport and
its surrounding land areas. Said map and all the information shown
thereon shall have the same force and effect as if all were fully
set forth or described herein. The original of this is properly attested
and is on file with the City Clerk.
1. Within the air space above the approach zone to each end of a runway
not designed to be used for instrument landings, no building or structure
or tree shall be erected or altered or permitted to grow to project
above a plane with a slope of one (1) vertical to twenty (20) horizontal
projected from a point two hundred (200) feet beyond the end of the
runway pavement for a distance of ten thousand (10,000) feet, said
plane to be oriented on the runway centerline and to be a symmetrical
trapezoid two hundred fifty (250) feet wide at its lowest point and
two thousand two hundred fifty (2,250) feet wide at its highest point.
2. Within the established transition zones adjacent to each non-instrument
runway and approach zone, no building or structure or tree may be
erected or altered or permitted to grow to project above a plane with
a slope of one (1) vertical to seven (7) horizontal. Transition zones
extend outward and upward from a line one hundred twenty-five (125)
feet on either side of the centerline of non-instrument runways for
the length of such runway plus two hundred (200) feet on each end,
to a height one hundred fifty (150) feet above the elevation of the
Airport Reference Point. In addition, transition zones are established
adjacent to non-instrument approach zones which flare outward and
upward symmetrically along the entire length of each approach zone
to where they intersect the surfaces of the horizontal and conical
zones.
3. Within five thousand (5,000) feet from the established Airport Reference
Point, no building or structure or tree shall be erected or altered
or permitted to grow to project above a horizontal plane one hundred
fifty (150) feet above the established airport elevation. This horizontal
plane does not include the approach or transition zones.
4. Within the conical zone which commences at the periphery of the horizontal
zone and extends outward and upward therefrom a distance of three
thousand (3,000) feet, no building or structure or tree shall be erected
or altered or permitted to grow to project above a plane with a slope
of one (1) vertical to twenty (20) horizontal.
5. Nothing in this Subparagraph on height regulations for airports shall
be construed as prohibiting the growth or construction of any tree
or structure to a height up to twenty (20) feet above the surface
of the land.

379.5, 5-18-1970; Ord. No. 732 §1, 7-20-1992]
A. When
forty percent (40%) or more of the frontage on one (1) side of the
street between two (2) intersecting streets is improved with buildings
that have a front yard which is greater or less than the required
front yard in the district, no building shall project beyond the average
front yard so established; provided however, that a front yard depth
shall not be required to exceed fifty percent (50%) in excess of the
front yard otherwise required in the district in which the lot is
located.
B. An
open, unenclosed porch or paved terrace may project into a front yard
for a distance not exceeding ten (10) feet. An unenclosed vestibule
containing not more than forty (40) square feet may project into a
front yard for a distance not to exceed four (4) feet.
C. Where
there are corner lots, the side yard next to the secondary street
shall be a minimum of seven (7) feet. As to houses constructed on
fifty (50) foot corner lots, said houses may be constructed facing
the secondary street with a minimum of a thirteen (13) foot front
yard and a minimum of a ten (10) foot back yard, and minimum of a
thirty (30) foot side yard fronting the main street. Further, no house
constructed on a fifty (50) foot corner lot facing a secondary street
shall have a back door on a section of said house where said house
abuts an adjoining lot.
[CC 1983 App. B Art. XIII §3; Ord. No.
379.5, 5-18-1970]
A. For
the purpose of the side yard regulations, a two-family dwelling, or
a multiple dwelling, shall be considered as one (1) building occupying
one (1) lot.
B. Whenever
a lot at the effective date of this Chapter (May 18, 1970) has a width
of less than sixty (60) feet, each side yard may be reduced to a width
of not less than ten percent (10%) of the width of the lot, but in
no instance shall a side yard be less than three (3) feet.
C. The
required side yard on the street side of a corner lot shall be the
same as the required front yard on such street, except that the building
width shall not be reduced to less than thirty-two (32) feet, and
no accessory building shall project beyond the required front yard
on either street.
D. Where
dwelling units are erected above a commercial establishment, no side
yard is required except when required for the commercial building
on the side of a lot adjoining a residence district.
E. Terraces,
uncovered porches, platforms, and ornamental features which do not
extend more than three (3) feet above the floor level of the ground
story may project into a required yard, provided these projections
be at least two (2) feet from the adjacent side lot line.
[CC 1983 App. B Art. XIII §4; Ord. No.
379.5, 5-18-1970]
A. Open-lattice
enclosed fire escapes, fireproof outside stairways, and balconies
opening upon fire towers, and the ordinary projections of chimneys
and flues into the rear yard may be permitted for a distance of not
more than three and one-half (3½) feet and where the same are
so placed as not to obstruct light and ventilation.
B. Not
more than ninety percent (90%) of the required rear yard area may

A. Where
a lot or tract is used for farming or for a commercial or industrial
purpose, more than one (1) main building may be located upon the lot
or tract, but only when such buildings conform to all open space requirements
around the lot for the district in which the lot or tract is located.
B. In
the event that a lot is to be occupied by a group of two (2) or more
related buildings to be used for multiple dwelling, institutional,
motel or hotel purposes, there may be more than one (1) main building
on the lot; provided however, that the open spaces between buildings
that are parallel, or within forty-five degrees (45°) of being
parallel, shall have a minimum dimension of twenty (20) feet for one-story
buildings, thirty (30) feet for two-story buildings, and forty (40)
feet for three-story or four-story buildings.
C. Accessory
buildings may be built in a required yard but such accessory buildings
shall not occupy more than thirty percent (30%) of a required rear
yard and shall not be nearer than two (2) feet to any side or rear
lot line, except that when a garage is entered from an alley, it shall
not be located closer than ten (10) feet to the alley line. If a garage
is located closer than ten (10) feet to the main building, the garage
shall be regarded as part of the main building for the purposes of
determining side and rear yards.
D. No
accessory building shall be constructed upon a lot until the construction
of the main building has been actually commenced, and no accessory
building shall be used for dwelling purposes.
[CC 1983 App. B Art. XIII §6; Ord. No.

inches into any required yard. Roofs and eaves may extend not more
than thirty (30) inches into any required yard.
B. Where
an open space is more than seventy-five percent (75%) surrounded by
a building, the minimum width of the open space shall be at least
twenty (20) feet for one-story buildings, thirty (30) feet for two-story
buildings, and forty (40) feet for three-story or four-story buildings.
