   (1)   Site development standards for permitted uses. Development shall be subject to the dimensional standards in Table 157.101-1, unless otherwise modified in the use specific standards or if specific site development standards exist for the conditional use in § 157.103.

1   The continuous frontage element of this standard may be reduced to 50 feet by the Planning and Zoning Commission for lots fronting on a permanent cul-de-sac or other curved street fronts (e.g., knuckles); provided that the width of any such lot shall increase from the front lot line to the required width at the building line 2   The minimum front yard setback shall be equal to the depth of existing front yards on the developed lots adjacent to or the subject lot if the developed lots are within 300 feet on the same block when 50% of such lots have a uniform building setback which is greater or less than required

 

   (2)   Minimum floor area requirements.

 

Table 157.101-2: Minimum Floor Area Requirements for Residential Dwellings
Unit Type	Minimum Square Feet in the R-R District	Minimum Square Feet in all Other Districts
One-story single-family dwellings	1,500	900
Multiple story single-family dwellings	900 on the first floor	750 on the first floor
Multi-family dwelling units or apartments in a mixed-use building	N/A	500 plus 150 for each bedroom

 

   (3)   Maximum lot coverage/maximum accessory use square footage.

      (A)   Table 157.101-3 defines the maximum lot coverage by principal structures and accessory structures in residential districts.

 

Table 157.101-3: Maximum Lot Coverage for Residential Uses
Lot Size	Maximum Lot Coverage by Principal Structures	Maximum Lot Coverage by Accessory Uses and Structures1
Up to 12,000 square feet	60%	10%
12,001 to 20,000 square feet	50%	10%
20,001 or more square feet	45%	15% with a maximum of 2,500 square feet
1   This coverage does not include the lot area covered by the principal structure. Accessory uses and structures that count toward this lot coverage are identified in § 157.087.

 

      (B)   In no case shall the total footprint of all accessory structures and buildings exceed the total footprint of the principal structure.

   (4)   Number of principal uses per lot. Only one principally permitted use may be permitted on a single lot with the exception of multi-family dwellings in the R-2 District where multiple dwellings may be located on a single lot. For the purposes of this provision, a two-family dwelling and a multi-family dwelling shall each be considered a single principal use. A secondary living unit may be considered as a conditionally permitted use (mother-in-law suite).

   (5)   Centralized water/sewer requirement. All development in the R-2 District shall be connected to an approved centralized sewer system and public water system.

   (6)   Open space requirements. The following open space requirements shall apply to any subdivision not subject to the open space residential subdivision requirements of § 157.102.

      (A)   Any subdivision greater than 15 acres in the R-1 District must reserve a minimum of 10% of the gross acres, excluding existing public easements and rights-of-way, as permanent open space.

      (B)   Any development in the R-2 District must reserve a minimum of 15% of the gross acres, exclusive of public or private right-of-ways, parking areas, land fragments between buildings or between buildings and parking areas, and minimum yards between property lines and buildings or parking areas.

   (7)   Multiple-family dwellings. Multiple-family dwellings may be permitted in the R-2 or PD Districts in accordance with the following provisions.

      (A)   In order to ensure and maintain individual privacy, dwellings in a multiple-family development shall be arranged and spaced in compliance with the Table 157.101-4.

 

Table 157.101-4: Dimensional Standards for Multi-Family Dwellings
Minimum building separation	50 feet; however, if the buildings are designed with primary living areas directly facing one another, the minimum separation shall be 85 feet
Minimum side and rear yard setback	25 feet plus 1 additional foot of setback for every 2 feet of wall length greater than 35 feet; this setback shall only apply when the adjacent walls are parallel to one another or are within 45 degrees of parallel

 

      (B)   The minimum building separation may be reduced by the PZC (through site plan review or PD plan approval) if they determine that adequate screening will be provided to ensure privacy for tenants.

      (C)   The arrangement of units within each building and between buildings shall maximize the privacy of each unit by providing screening walls and private yards where appropriate.

      (D)   Dwelling units in a multi-family dwelling shall meet the minimum floor area requirements as established in division (2) of this section.

      (E)   There shall be a maximum impervious surface ratio of 70% for lots developed for multi-family dwellings.
