Single-family dwellings and two-family dwellings may be increased in height by not more than ten (10) feet when the side and rear yards are increased over the yard requirements for the district in which they are located by not less than ten (10) feet each, but they shall not exceed three (3) stories in height.

Chimneys, cooling towers, elevator bulkheads, fire towers, monuments, stacks, stage towers or scenery lofts, tanks, water towers, ornamental towers and spires, radio towers or necessary mechanical appurtenances may be erected to a height in accordance with existing or future ordinances of the City.

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 unless the main building on the lot is also being used for dwelling purposes.

More than one (1) industrial, commercial, multiple dwelling or institutional building may be erected upon a single lot or tract, but the yards and open spaces required around the boundaries of the lot or tract shall not be encroached upon by any such buildings, nor shall there be any change in the intensity of use requirements.

The minimum distances between main buildings, where more than one (1) multiple dwelling building is erected upon a single lot, shall be as follows:

Where an open space is more than fifty percent (50%) surrounded by buildings, the minimum width of the open space shall be thirty (30) feet for one-story buildings, forty (40) feet for two-story buildings and fifty (50) feet for three-story buildings.

In computing the depth of a rear yard, where such yard opens into an alley, one-half (½) of the alley width may be included as a portion of the rear yard.

Accessory buildings which are not a part of the main building may be built in a rear yard within five (5) feet of the rear lot building line. An accessory building which is not a part of the main building shall not occupy more than thirty percent (30%) of the required rear yard.

Every part of a required yard shall be open to the sky, unobstructed, except for accessory buildings, in a rear yard and except for the ordinary projections of skylights, sills, belt courses, cornices and ornamental features projecting not to exceed twelve (12) inches. This requirement shall not prevent the construction of fences not exceeding eight (8) feet in height, except on that portion of lots within thirty (30) feet of the intersection of two (2) or more streets.

Open or lattice-enclosed fire escape, fireproof outside stairways and balconies opening upon fire towers projecting into a yard not more than five (5) feet and the ordinary projections of chimneys and flues may be permitted by the Building and Zoning Officer.

An enclosed vestibule containing not more than forty (40) square feet may project into the required front yard for a distance not to exceed four (4) feet.

Terraces, uncovered porches, platforms and ornamental features which do not extend more than three (3) feet above the floor level of the first (1st) (ground) story may project into a required yard, provided these projections be distant at least two (2) feet from the adjacent side lot line.

When forty percent (40%) of a frontage is developed with two (2) or more buildings, then the depth of the front yards heretofore established shall be adjusted in the following manner:

In all districts a triangular space must be maintained at the street corner of a corner lot, free from any kind of obstruction to vision between the heights of three (3) and twelve (12) feet above the established street grade. The street grade shall be measured at the intersection of the centerlines of the intersecting street pavements and the triangular space is determined by a diagonal line connecting two (2) points measured fifteen (15) feet equidistant from the intersection of the property lines or the property lines extended on the corner of the lot using each of the street right-of-way lines.

In single-family dwelling districts "R-l" and "R-2", when eighty percent (80%) of the frontage of a block on both sides of the street between two (2) intersecting streets or between an intersecting street and a cul-de-sac has been developed with main buildings and accessory buildings with side yards less than that required by the dwelling district in which said property is situated, then the side yard requirement for any main buildings or accessory buildings in said block shall be the average yard of all parcels of property in said block rather than the side yard set forth in the dwelling district in which said parcel of property is situated. In determining the existing side yard of any developed parcel in order to compute the average herein, the side yard of the main building on any developed parcel shall be used except that when an accessory building exists with a smaller side yard than the main building has, the side yard shall be taken as being the average between the side yard of the main building and the side yard of the accessory building.

All buildings and structures erected and all land uses shall provide accessory off-street parking or loading facilities as required hereinafter for the use thereof.

When a building or structure erected or enlarged prior to or after the effective date of this Chapter shall undergo a decrease in number of dwelling units, gross floor area, seating capacity, number of employees or other unit of measurement specified hereinafter for required off-street parking or loading facilities and, further, when said decrease would result in a requirement for fewer total off-street parking or loading spaces through application of the provisions of this Chapter, off-street parking and loading facilities may be reduced accordingly, provided that existing off-street parking and loading facilities are so decreased only when the facilities remaining would at least equal or exceed the off-street parking or loading requirements resulting from application of the provisions of this Chapter to the entire building or structure as modified.

When a building or structure undergoes any increase in number of dwelling units, gross floor area, seating capacity or other unit of measurement specified hereinafter for required off-street parking or loading facilities and, further, when said increase would result in a requirement for additional total off-street parking or loading spaces through application of the provisions of this Chapter, parking and loading facilities shall be increased so that the facilities would at least equal or exceed the off-street parking or loading requirements resulting from application of the provisions of this Chapter to the entire building or structure as modified.

Requirements governing the number and location of off-street parking, off-street loading facilities in relation to the use of property are established hereinafter in Subsections of this Section. The off-street parking and loading requirements for any use not specified therein shall be the same as for similar specified use as hereinafter set forth.

In any case where the required parking spaces are not located on the same lot with the building or use served or where such spaces are collectively or jointly provided and used, a written agreement thereto assuring their retention for such purposes shall be properly drawn and executed by the parties concerned, approved as to form and execution by the City Attorney and shall be filed with the application for a building permit.

Provided however, that written agreement, assuring the retention of such purpose shall be properly drawn and executed by the parties concerned, approved as to form and execution by the City Attorney and shall be filed with the application for a building permit.
