Side yard setbacks on corner lots shall be ten feet, except as provided in footnote no. 2.
 
c.

4.
Where a minimum size is not specified, the intention of this chapter is that each lot shall be of sufficient size and dimension and with access to a public right-of-way and utilities for its intended use after complying with the requirements set forth in this chapter and other applicable ordinances and is compatible with those uses around it.
5.
Unenclosed carports accessing and abutting an alley may be built up to the rear property line in the R-3A and R-3C zone districts.
6.
See off-street parking and loading, article VII of this chapter.
7.
Only one primary residential structure may be erected on an R-1, R-2 or R-3T zoning district lot; and only one single-family residential structure may be erected on an R-3A or R-3C zoning district lot.
8.
The board of commissioners has the power to pass an ordinance establishing a setback line greater than in the above table where exceptional conditions so require.
9.
Where a structure exceeds the 25-foot height maximum, it shall be set back one additional foot for each foot above 25 feet.
10.
Where a townhouse is not separated from an adjacent structure by a firewall, the setback from each side lot line shall be six feet each side. Side yard setback on corner lots shall be ten feet, except as provided in footnote no. 2.
11.
Standards and specifications:
 
a.
Setback, area and height limitations in commercial areas (in general):
 
 
(1)
The limitations on setbacks, area and height are intended to control all areas zoned and platted for commercial uses after the adoption of the ordinance from which this chapter is derived. Recognizing the inherent problems affecting property in the central business district, these restrictions will not be applicable in that area. Parcels zoned and platted for commercial purposes existing at the time of the adoption of the ordinance from which this chapter is derived that are 50 feet or less in width are also exempted from these restrictions. In those instances, reference will be made to the 1945 zoning ordinance as controlling these areas.
 
 
(2)
All commercially and industrially zoned property that has frontage along U.S. Business 83 shall be exempted from the setback requirements set forth in this chapter, and shall be controlled by the 1945 zoning ordinance which is on file in the city secretary's office. The exemption from setbacks shall be tied to the zoning designation, regardless of the date that such zoning became or becomes effective.
 
b.
Setback, area and height limitations in commercial areas (specific):
 
 
(1)
A ten-foot side yard setback shall be required on corner lots.
 
 
(2)
The minimum width of a building site shall be 50 feet of frontage on a public street.
 
 
(3)
The minimum front yard setback shall be equal to 15 feet.
 
 
(4)
Side yard setbacks from all lot lines shall be one foot back for each two feet in height including corner lots or, if not adjacent to residential uses, may provide a firewall in accordance with Building Code requirements in lieu of a setback.
 
 
(5)
Rear yard setbacks shall be five feet.
 
 
(6)
The height of buildings may not exceed the depth of the front yard plus the width of the street right-of-way which it faces. In a C-1 or C-3L zone districts the maximum height shall not exceed two stories.
12.
Seven thousand square feet represents the minimum lot area for any R-3 multifamily residential district use, exclusive of townhouse. Zero bedrooms, 800 square feet; three bedrooms, 1,500 square feet, represents the "minimum lot area/dwelling unit in square feet" permitted within this control category. To determine the permitted number of dwelling units in the R-3 multifamily residential district, divide the "minimum lot area per dwelling unit" for the type of unit desired (or the average for a variety) into the lot area for the parcel in question. The resulting quotient is the maximum number of dwelling units permitted, e.g.:
80-foot by 120-foot lot = 9,600 square feet
0 br. 800 square feet
9600
800
=

Maximum dwelling units on 9,600-square-foot lot = 12 efficiencies

Maximum density per gross acre in the R-3 multifamily residential district is expressed as 54/29. The number 54 represents the maximum number of "0 bedroom, 800-square-foot dwelling units" permitted on a one-acre tract. The number 29 represents the maximum "3 bedroom, 1,500-square-foot dwelling units" permitted on a one-acre tract, e.g.:
43,560

=

14.

§ 138-367 Front yards.

(a) 
When 50 percent or more of the frontage on one side of a street on any one block is improved with buildings that have a front yard which is greater than the required front yard in the district, no new building shall project beyond the average front yard so established or the front yard setback set by this chapter.
(b) 
Where lots have double frontage, running through from one street to another, a required front yard shall be provided on one street only.
(c) 
In a residential district, no fence, structure or planting higher than three feet above the streetflow gutter line shall be maintained within 25 feet of the curb intersection. Palm trees or similar small trunk trees or vegetation may occupy this area provided that the foliage is continuously trimmed a minimum of eight feet above street grade.

(a) 
On a corner lot in all districts, the width of the side yard along the street shall not be less than ten feet provided that the buildable width of such a lot of record shall not be reduced to less than 38 feet. This regulation shall not apply to those lots of record which have existing buildings prior to the date of the ordinance from which this chapter is derived. However, should these buildings be removed, destroyed or in any way eliminated from the property, they shall thereafter comply with this chapter. Corner lots subdivided after the date of the ordinance from which this chapter is derived shall be at least four feet wider than the minimum lot size in residential zones and ten feet wider in commercial zones.
(b) 
No accessory building shall project into the required yard along any street.
(c) 
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 residential district.
(d) 
A porte-cochere or canopy may project into a required side yard provided every part of such porte-cochere or canopy is unenclosed and not less than four feet from any side lot line or eight feet from a corner property line.
(e) 
For the purpose of side yard regulations, a multiple dwelling shall be considered as one building occupying one lot.
(f) 
Where a lot of record at the time of the effective date of the ordinance from which this chapter is derived is less than 50 feet in width, the required side yard may be reduced to ten percent of the width of the lot, provided that no side yard shall be less than 3½ feet.
(g)

(1966 Code, § 32-58(5))

§ 138-371 Special exception for carports.

(a)

There is no adequate vehicular access to an area behind the required front building line that would accommodate a parking space; and
(2) 
The carport will not have a detrimental impact on surrounding properties.
(b) 
In determining whether to grant this special exception, the board shall consider the following factors:
(1) 
Whether the requested special exception is compatible with the character of the neighborhood.

(e) 
Any special exception granted under this chapter is granted solely to the applicant and may not be transferred, sold, inherited, bequeathed, or devised.
(f)

(g) 
No carport for which a special exception has been granted under this subsection shall exceed 400 square feet in size.
(Ordinance 2018-70, § I, adopted 10/8/2018; Ordinance 2023-85 adopted 6/26/2023)

(c) 
In determining whether to grant this special exception, the board shall consider the following factors:
(1) 
Whether the requested special exception is compatible with the character of the neighborhood.
(2) 
Whether the value of surrounding properties will be adversely affected.
(3) 
The suitability of the size and location of the tree house.
(4) 
The materials to be used in construction of the tree house.
(d)

Any special exception granted under this chapter is granted solely to the applicant and may not be transferred, sold, inherited, bequeathed, or devised.
(f) 
A new special exception shall be required upon any change or transfer in ownership of the underlying tract; a special exception granted to a previous applicant does not confer any right to any other individual or corporation to maintain the carport without approval from the zoning board of adjustment.
