TABLE NOTES:
1.
In certain circumstances, a greater open space ratio may be required to protect floodplains. Planned cluster development offers the highest densities with the greatest amount of open space for resource protection purposes.
2.
Lots in the R-1 and R-2 zoning districts that exist prior to the effective date of this UDC shall follow the development standards and lot and building standards as are set out on approved preliminary or final plats, as follows: Minimum side yard = 5'; minimum street side yard = 5'; minimum rear yard = 15'; minimum front yard = 20'; and minimum lot area = 5,000 sf.
3.
The minimum area of the parcel proposed for development of a new planned cluster development is 10 acres.
4.
The minimum and maximum area of the parcel proposed for development of a manufactured home park or subdivision is set out in subsection 4.203B, Minimum and Maximum Site Area.
5.
The minimum and maximum area of the parcel proposed for development of a recreational vehicle park is set out in subsection 4.204C, Minimum and Maximum Site Area.
6.
Townhouses shall not have more than six units per building and each building shall be separated by a minimum of 25 feet.
7.
In addition to the common area needed for meeting the minimum open space requirements for the entire parcel proposed for development, the minimum lot size consists of 9,000 sf for duplexes (two dwelling units at 4,500 sf each), 6,600 sf for triplexes (three dwelling units at 2,200 sf each), and 12,000 sf for townhouses (up to six dwelling units at 2,000 sf each). The minimum lot area per dwelling unit may be platted as a single lot (with a condominium form of ownership), or as separate lots (e.g., three lots at 2.200 [2,200] sf for triplexes under fee-simple form of ownership). See also Section 3.102, Alternate Standards for Condominium and Alternate Land Ownership Patterns).
8.
The street side setback is also the minimum side setback for end units.
9.
The minimum principal dwelling size shall be for one bedroom – 800 square feet; two bedroom – 1000 square feet; three bedroom – 1,200 square feet.

TABLE NOTES:
1.
In certain circumstances, a greater open space ratio may be required to protect floodplains.
2.
Multifamily apartment buildings shall be separated by a minimum of 25 feet.
3.
In addition to the common area needed for meeting the minimum open space requirements for the entire parcel proposed for development, the minimum lot size consists of the specified lot area per dwelling unit.

E. 
Requirements for Phased Developments.
Projects that are proposed to be phased shall demonstrate compliance with this Section using the entire parcel proposed for development regarding the calculation of minimum open space ratio and maximum gross density.
F. 
Accessory Buildings and Structures.
The standards for accessory buildings and structures are set out in Section 11.101, Accessory Buildings and Structures, and Section 11.102, Accessory Dwelling Units, which apply to both new and established neighborhoods.
(Ordinance 2015-30 adopted 10/30/15; Ordinance 2018-09 adopted 8/13/18)
A. 
Generally.
The standards of Section 3.101, Development Standards for New Residential Neighborhoods, with respect to lot area, lot width, and setbacks relate to the development of residential buildings on conventional lots that are intended to be owned in fee-simple by the owners of the buildings. However, the standards are not intended to preclude other ownership types, such as single-ownership of all units (rentals); condominiums (in which the land is owned in common by the owners of the condominium units); or common maintenance communities (in which fee-simple ownership is limited to the land under the building, and, in some cases, a small area around it). The alternative standards of this Section are intended to allow such alternative ownership arrangements, provided that the development could be approved pursuant to this UDC using conventional fee-simple ownership arrangements.
B. 
Demonstration of Compliance.
The proposed pattern of development will be allowed if it is demonstrated that it would comply with the density, open space, and applicable setback requirements of this UDC if it were platted with lots that meet the minimum requirements of Section 3.101, Development Standards for New Residential Neighborhoods, and other applicable standards of this UDC.
