A.
The following are detailed descriptions of the residential zoning districts and their respective dimensional and bulk regulations, requirements, and design standards. The various development options indicated are "open space ratio," or OSR, driven. While the overall maximum gross density stays essentially the same within each residential zoning district for each option within a specific residential zoning district, as the minimum OSR increases the maximum permitted net density increases. Under the "conventional" and other options presented for each residential zoning district, the site intensity and capacity calculations, as well as the natural resource protection standards and guidelines set forth in Divisions 15-3.0500 and 15-4.0100 of this Ordinance, shall be adhered to.
B.
It is the expressed intent of this Ordinance that each buildable lot of land, with an on-site sewage disposal system, whether existing or newly subdivided, shall conform to a minimum lot size of 40,000 square feet and minimum lot width of 150 feet, regardless if the lot conforms with a conventional or a special use OSR subdivision. Therefore, a special use OSR subdivision shall not circumvent minimum sizes with an on-site sewage disposal system.
C.
Every type of dwelling unit or structure hereafter referenced to, erected in any residential zoning district, shall have a minimum living area in square feet measured from the outside of the exterior walls, including utility rooms, foyers, interior stairwells, hallways, closets, columns, and walls, and finished half-basements or finished portions of half-basements, but excluding basements and unfinished half-basements, or unfinished portions of half-basements, open porches, breezeways, garages, and other spaces not used frequently or during extended periods for living, eating, or sleeping purposes in accordance with this Division. If the finished area of a half-basement or finished portion of a half-basement are included in the minimum living area of a dwelling, the dwelling shall be automatically considered multi-story and shall meet the minimum square footage requirements for multi-story.
A. 
District Intent. The R-1 District is intended to:
1. 
Permit residential development at intensities that are consistent with the maintenance of a COUNTRYSIDE/ESTATE character and a COUNTRYSIDE/ESTATE life-style as set forth in the City of Franklin Comprehensive Master Plan and components thereof.
2. 
Serve as a transitional district between the more RURAL areas or farmland areas and the more SUBURBAN intensity areas of the City.
The options in this district promote open space protection and natural resource base protection. It is the most RURAL of the residence land use districts.
B. 
District Standards. The R-1 District is further intended to have the development standards as set forth in Table 15-3.0201.
C. 
Permitted, Accessory, and Special Uses. See Section 15-3.0602, Division 15-3.0700, Section 15-3.0702, and Section 15-3.0802 of this Ordinance.

A. 
District Intent. The R-1E District is intended to:
1. 
Provide for EXECUTIVE type developments to allow for multiple attached and detached dwelling units with larger lot sizes, and moderate building, bulk and setback requirements to allow for accessory uses such as guest homes, caretaker quarters, family care providers and multi-generational living options, while providing adequate buffers for adjacent lower density residential developments.
2. 
No additional dwelling structure or an accessory structure shall be permitted upon a lot until an occupancy permit has been issued for a principal structure meeting the requirements of Table 15-3.0201E.
3. 
Dwelling units shall not be for rent, for multiple occupancy developments or uses found under SIC Code No. 7011 Hotels and Motels. Additional dwelling units shall be utilized by permitted uses or members of the functional family unit.
4. 
The Plan Commission may consider more than two principal buildings per lot where more than two principal buildings are needed for the orderly development of the parcel. When additional structures are permitted, the Plan Commission may impose additional yard requirements, floor area ratio limitations, residential density requirements, land use intensity requirements, landscaping requirements, or parking requirements, or may require a minimum separation distance between principal buildings.
5. 
A property zoned R-1E District shall connect to the public sanitary sewer system and/or the public water system when such system(s) are available, as may otherwise be proscribed and required by the Municipal Code. A property zoned R-1E District, its primary zoning purpose being to support more than one dwelling unit, shall be considered a reason in favor of any proposed extension of pubic sanitary sewer or water abutting such property in the consideration thereof, and as such, deemed a property owner vote in favor of such extension upon any property owner survey which may be conducted or considered by the Common Council upon such proposed extension.
6. 
Multiple dwelling units located on a single lot shall be positioned to be harmonious to one another for the orderly development of the parcel and compatible with adjacent land uses. All structures shall consist of high quality building materials and architectural design.
7. 
Be used in conjunction with and adjacent to other single-family residence districts, especially for development of infill lots and/or lots containing a significant amount of protected natural resource features. May also be used as a transitional district to other higher intensity multi-family residential use districts as greater setbacks are required.
B. 
District Standards. The R-1E District is further intended to have the development standards as set forth in Table 15-3.0201E.
a. 
All dwelling structures shall meet the following minimum setbacks (The total height of the structure is measured from grade to the highest point of the structure. In instances where there is a slope in grade height is measured from the lowest point of the slope):
