The City Council hereby finds that uniformity in the exterior design
and appearance of buildings erected in the same residential neighborhood for
occupancy as dwellings adversely affects the desirability of immediate and
neighboring areas for residence purposes and by so doing impairs the benefits
of occupancy of existing residential property in such areas, impairs the stability
and value of both improved and unimproved real property in the areas, prevents
the most appropriate use of real property, prevents the most appropriate development
of the areas, produces degeneration of residential property in such areas
with attendant deterioration of conditions affecting the health, safety and
welfare of the city and its inhabitants in that it deprives the municipality
of tax revenue which it otherwise could receive and destroys a proper balance
in relationship between the taxable value of real property in such areas and
the cost of the municipal services provided therefor. It is the purpose of
this chapter to prevent these and other harmful effects of uniformity in the
exterior design and appearance of buildings erected in the same residential
neighborhood for occupancy as dwellings and thus to promote and protect the
health, safety and welfare of the city and its inhabitants.
As used in this chapter, the following terms shall have the meanings
indicated:
MAIN ROOF
A.
FLAT AND SHED ROOFS:
(1)
That portion of the roof having a common plate height and covering the
largest volume of enclosed space, exclusive of the floor area, below finished
grade at the front elevation.
(2)
All flat roofs shall be deemed identical in the distance of the roof
above the plate line.
B.
GABLE, HIP, MANSARD OR OTHER ROOFSThat portion of the roof having a common plate and ridge height and covering the largest volume of enclosed space, exclusive of the floor area, below finished grade at the front elevation. Dormers and intersections with other parts of the roof within a common plate line will be deemed part of the main roof.
NEIGHBORING BUILDING
Any building in existence or for which a building permit has been
issued at the time application is made for a building permit for the proposed
building site and which is located on:
A.
Either side of a street on which the proposed building site abuts and
within 300 feet thereof, exclusive of intervening streets, the distance being
measured along the street center line from its intersection with the projection
line of the neighboring building; or
B.
Another street which intersects a street on which the proposed building site abuts and adjoining any neighboring building defined by Subsection
A above.
PROJECTION LINES
Straight lines perpendicular to the center line of the adjacent street
and embracing the proposed building site or a neighboring building.
Except as otherwise provided in this chapter, no building permit shall
be issued for the erection of any one-family residence unless it differs from
any neighboring building in at least four of the following respects:
A. The height of the bottom of the main eave line above
the first floor or the height of the main roof ridge above the top of the
plate must differ in height by at least two feet.
B. The length of the main ridge or, in the case of a flat
roof, the length of the main roof must differ by at least four feet.
C. The length between outside walls of the building, measured
under the main roof at right angles to the building width, the difference
must be at least three feet.
D. The width between outside walls of the building, measured
under the main roof at right angles to the building length, the difference
must be at least three feet.
E. Portions of the building not located under the main roof
shall differ in at least two of the following ways:
(1) Horizontal distance between the portion and the nearest
corner in the front elevation of the building under the main roof shall differ
by at least three feet, measured at right angles to the front elevation.
(2) Height of the eave line of the portion, measured above
the first floor under the main roof, shall differ by at least two feet.
(3) Length of front elevation of the portion shall differ
by at least three feet.
F. In the front and each of the side elevations, the distance
between door and window openings must differ in at least two of the following:
(1) The horizontal distance between openings must differ
by at least two feet.
(2) The horizontal distance between openings and the following
architectural elements must differ by at least two feet:
(a) Corners of the building under the main roof.
(b) Corners of the building not under the main roof, including
projecting chimneys.
(3) The vertical distance between floor level and the lower
edge of window openings of each floor must differ by at least one foot.
