All primary and accessory structures are subject to the dimensional standards set forth in the tables in this section. These general standards may be further limited or modified by other applicable sections of this Development Code. General rules for measurement and exceptions are in Section 4.2, Measurements and Exceptions.

4.1.1.

Residential Districts.

4.1.2.

Mixed-Use Districts.

4.1.3.

Nonresidential and Other Districts.

* The maximum height can be established at the setback line if the setback is adjacent to railroad and at least 250-feet away from any existing residential home, though the maximum height will still be required to meet the incremental height allowances on all other sides of the project parcel that may result in only portions of the railroad adjacent to the building permitted to achieve the maximum height at the setback line.

4.2.1.

Density.

A.

Acre, Gross. Means a measure of land area (43,560 square feet).

B.

Density. Means the number of dwelling units allowed for each gross acre of land, and is determined by dividing the number of dwelling units on a site by the gross acreage of the site, including dedicated rights-of-way, private streets, and open space set asides. In the determination of the number of residential units to be allowed on a specific parcel of land, a fractional unit equal to or greater than one-half of a unit shall be rounded up to equal a full unit.

C.

Dwelling Units Allowed. The number of dwelling units allowed on a site is based on the presumption that all other applicable standards of this Development Code shall be met. The maximum density established for a zoning district is not a guarantee that such densities may be obtained, nor a valid justification for varying or modifying other dimensional or Development Standards.

4.2.2.

Lot Size.

A.

Minimum Lot Dimensions. Any lot that is created, developed, used, or occupied shall meet the minimum lot size and frontage requirements in Tables 4.1-1, 4.1-2, and 4.1-3 for the zoning district in which it is located, except as otherwise established in this Development Code for particular uses. New lots shall also meet the Development Standards set forth in Section 6.3.6, Lots. Single-Family Flex (SFF) Districts are exempt from Section 6.3.6.

B.

Number of Principal Buildings or Uses Per Lot.

1.

Only one main building for single-family or two-family with permitted accessory buildings may be located upon a lot. Single-Family Flex (SFF) Districts are exempt from this provision. Every dwelling should face or front upon a street. Single-Family Flex (SFF) Districts are exempt from this provision if they are internal to the development.

2.

Where a lot or tract of land is used for mixed use, commercial, or industrial purposes, more than one main building may be located upon the lot but only when such buildings conform to all requirements of this Development Code applicable to the uses and district.

4.2.3.

Setbacks.

A.

Required Setbacks.

1.

A building, structure, or lot shall not be developed, used, or occupied unless it meets the minimum setback requirements set forth in Section 4.1 for the zoning district in which it is located. Setbacks shall be measured from the lot or property lines. Single-Family Flex (SFF) District dimensions shall be measured from the perimeter property lines.

2.

A setback or other open space required by this Development Code for one building, structure, or lot shall not be included as part of a setback or other open space required by this Development Code for another building or structure or lot.

B.

Projections into Required Setbacks, General. Setbacks shall be unoccupied and unobstructed by any structure or portion of a structure from 30 inches above grade upward, except that certain structures may project into required front, side, or rear setbacks as specified in this subsection. Any structure covered with a roof or lattice shall count toward maximum lot coverage restrictions:

1.

Paved Terraces. Paved terraces may project into any required setback, provided that no structures placed there shall violate other requirements of this Development Code and are at least one foot from the property line.

2.

Unroofed Landings, Decks, Stairs and Balconies. Unroofed landing, decks, and stairs may project into required setbacks, provided that no portion other than a handrail shall extend higher than 30 inches above the finished grade level. Unroofed balconies may project into a required side or rear yard provided these projections are at least five feet from the side lot line and ten feet from the rear lot line.

3.

Incidental Architectural Features. Cornices, eaves, overhangs, canopies, sunshades, gutters, chimneys, flues, belt courses, headers, sills, pilasters, lintels, ornamental features, and other similar architectural features may project not more than three feet into any required front yard and two feet beyond the required side or rear yard provided these projections are at least three feet from the lot line.

4.

Roofs Over Porches and Other Exterior Approaches. Roofs or lattice structures over porches, patios, stairways, landings, terraces or other exterior approaches to pedestrian doorways may encroach up to five feet into a front setback area.

The posts of an attached roof or lattice structure shall follow the principal structure side yard setback and shall be setback ten feet from the rear property line. The roof or lattice structure may overhang up two feet into the aforementioned rear yard setback and side yard setbacks.

Such structures shall be enclosed by no more than a railing or screen.

C.

Projections into Easements and Rights-of-Ways Prohibited. Projections shall not extend or encroach into any easement(s) or right(s)-of-way unless approved by the Public Works Department, within a public utility easement, and have a written confirmation that public utilities in the area approve of the design shall be provided to the city.

D.

Americans with Disabilities Act (ADA) Ramps. ADA access ramps may be located within required front, side, and rear setbacks.

E.

Bay Windows. Bay windows that are not more than eight feet in width where the projection breaks the plane of the wall may project no more than three feet into any required yard setback.

F.

Private Garages and Carports. A private garage or carport may project into a required setback abutting a public alley, in accordance with other requirements of this Development Code.

G.

Contextual Front Setbacks. The following exceptions to the front setback requirements for dwellings fronting local streets, not collector or arterial streets, are authorized for a lot in any district.

1.

If there are dwellings on both abutting lots with front setbacks of less than the required depth for the district, the front setback of the lot need not exceed the average front setback of the abutting dwellings.

2.

If there is a dwelling on one abutting lot with a front setback of less than the required depth for the district, the front setback for the lot need not exceed the average of the required setback and the front setback of the abutting dwelling.

H.

Double-Frontage Lots. In the case of double-frontage lots, front setbacks shall be provided on all frontages, unless the prevailing front setback pattern on adjoining lots allows for an exception under the contextual front setback provision above.

I.

Setbacks from Private Roads. Whenever a private road serves more than three lots/dwelling units or serves any non-residential use tending to generate traffic equivalent to more than three dwelling units, all setbacks shall be provided in conformance with those setbacks required for lots served by public streets. Single-Family Flex (SFF) Districts are exempt from this requirement.

4.2.4.

Building Height.

A.

Height Requirements Generally. No building shall be erected or altered that will exceed the height limit for the respective zoning district, unless otherwise provided in subsection B.

B.

Height Exceptions for Appurtenances. Except as specifically provided elsewhere in this Development Code, the height limitations contained in this Development Code do not apply to cupolas, flagpoles, chimneys, antennas, heating and ventilation equipment, elevator housings, stairwell towers or similar appurtenances; provided, however, the following:

1.

The appurtenance does not interfere with Federal Aviation Administration regulations;

2.

The appurtenance does not extend more than 25 feet above the maximum permitted building height, except for flagpoles, church belfries, and antennas that must be of greater height in order to function;

3.

The appurtenance is not constructed for the purpose of providing additional floor area in the building; and

4.

The appurtenance complies with the screening requirements for mechanical equipment and appurtenances in Section 5.4.6, Fences, Walls, and Screening.

C.

Height Exceptions for Structures. The height regulations of this Development Code shall not apply to barns, silos, cooling towers, fire towers, monuments, public art, or water tanks provided the structure does not exceed 75 feet in height and does not occupy a horizontal area in excess of 150 square feet.
