In R1-A, R1-C and R2-F zoning districts, buildings and land shall be used, and buildings shall be erected, altered, moved and maintained, only in accordance with the lot area, yard and building height regulations set forth in this chapter.
(a) Each single and two-family dwelling and townhouse cluster dwelling unit shall abut upon a dedicated street for the required minimum lot width, except on curved streets. On curved streets, the width at the front line may be less than the minimum lot width, provided that the lot width at the front building line meets the required lot width of the particular district and provided, further, that:
(1) The distance from the building line to any point on the rear lot line is not less than ninety feet; and
(2) The arc distance of the front lot line of a cul-de-sac lot is not less than sixty feet.
(3) Corner lots in a R1-A zoning district shall have a minimum lot width of ninety feet and one-hundred-twenty-five feet; respectively.
(b) Required Yards to be Maintained. In R1-A, R1-C and R2-F zoning districts, no required yard surrounding an existing building shall be separated in ownership from the portion of the lot upon which the building is located, and no part shall be considered as providing a required yard for any other existing building on the same or on an adjacent lot.
(1) No yard shall be reduced to less than the required dimensions for the district in which it is located by enlarging an existing building, nor shall a yard which is less than the required dimensions be further reduced in any manner.
(2) Every required yard shall be open and unobstructed from the ground upward, except for accessory buildings as set forth in Chapter 1141 and projections into yards as set forth in Section 1131.08(f).
(c) Front Yards of Partially Built Residential Street Blocks.
(1) In R1-A, R1-C and R2-F zoning districts, if fifty percent (50%) or more of the aggregate street frontage between two successive intersecting streets is occupied by buildings of the type and use permitted in the district before the effective date of this Zoning Code, or any amendment thereto, with a front yard setback of less than that required by this Zoning Code, the minimum front yard setback for new buildings shall be the average setback distance of existing buildings located within 200 feet on either side of the lot seeking the determination.
(2) However, the depth of the front yard setback shall be not less than one-half of the minimum distance required in the respective zoning district.
(d) Side Yards of Insufficient Width. In R1-A, R1-C and R2-F zoning districts, if side yards are narrower than the required minimum side yard setback for the district in which the building and lot are located and such lot was owned separately from all other tracts of land on the effective date of this Zoning Code, or any amendment thereto, and is still so owned, the building may be maintained or altered, but may not be enlarged in width unless the minimum side yard setback distance established for the respective zoning district can be maintained.
(e) Front Yard Setback on Corner Lots. The depth of the front yard setback on a corner lot in any residential zoning district, shall not be less than the required minimum front yard setback distance as established for the respective zoning district.
(f) Projections Into Yards. As used in this chapter, “projection” means that part or feature of a building which extends or projects outside of the enclosing walls. It is intended that certain features may project into the yards required in R1-A, R1-C and R2-F zoning districts, but such features shall be regulated so as not to substantially interfere with the reception of sun, light, air and the use of adjacent lots. Building features may project into a front, side, or rear yard of a dwelling measured from the established yard line, as follows:
(1) Architectural features. An architectural feature, including a belt course, balcony, cornice, gutter or chimney, may project into a front and side yard for a distance of two feet, provided that no part is less than three feet from any side lot line.
(2) Entrance features. An entrance feature, including an open platform, landing, step, terrace or any other feature not extending above the first floor level of a building, may extend six feet into a front yard and three feet into a side yard.
(3) Enclosed shelters. An enclosed shelter, including an enclosed entry or porch, shall not project into any required yard area.
(4) Unenclosed shelters. An unenclosed shelter, including an entrance hood or open, but roofed porch, may project six feet (6') into a front yard and three feet into a side yard.
(5) Decks. An unenclosed and uncovered platform such as a deck or open porch shall be located as follows:
A. R1-A and R2-F zoning districts. A minimum setback of twenty-five feet from the rear lot line shall be maintained.
B. R1-C zoning district. A minimum setback of eighteen feet from the rear lot line shall be maintained.
(6) Mechanical equipment. Mechanical equipment serving a residential dwelling may be located in either the rear yard or side yard area unless stated otherwise in this Code. Such equipment may encroach into the minimum side yard setback so long as the equipment maintains a minimum setback of eight feet from the side property line.
A. Generators. A generator may only be permitted in a rear yard area.
B. Air conditioner equipment. Air conditioner equipment may be permitted in a side yard subject to review and approval by the Building Commissioner. Any approved side yard placement shall require an approved method for screening the equipment.
(g) Required Residential Lot Area to be Maintained. A parcel of land may be subdivided into two or more parcels in R1-A, R1-C and R2-F zoning districts, provided that all lots resulting from such subdivision conform to all the lot area and width regulations of the zoning district in which it is located.
(1) No lot of record which conformed to the provisions of this Zoning Code and which was owned separately from adjoining lots on the effective date of this Zoning Code, or any amendment thereto, which affected its conformity, shall be reduced in any manner which would make it nonconforming.
(2) No lot area, or any part thereof, required for a dwelling or any other use shall be considered as providing any part of the required lot area for another dwelling or use.
(h) Number of Structures Permitted on a Single Lot.
(1) In the R1-A, R1-C and R2-F zoning districts, there shall be not more than one single-family dwelling or one two-family dwelling permitted on a lot.
(2) There may be one detached garage, one enclosed accessory building, and one unenclosed accessory building, such as a gazebo, on the same zoning lot with a main building, provided that such accessory buildings and detached garage are constructed subsequent to the main building.
(3) No single-family dwelling or two-family dwelling shall be located to the rear of any building on the same lot or on another lot which does not have the required frontage on a dedicated street. However, townhouse cluster dwellings and apartment buildings may be arranged in groups and each building need not directly front on a dedicated street.
(i) Minimum Livable Square Footage for a Dwelling.
(1) The calculation of minimum livable floor area for permitted dwellings within the R1-A, R1-C or R2-F zoning districts shall be exclusive of any garages, cornices, eaves, gutters, porches, balconies, terraces, outside enclosures or basements.
(2) Basement areas meeting the ingress and egress requirements of the Building Code shall not be included in the calculation of livable square footage of a dwelling under this chapter.
(j) Ownership and Maintenance for Common Area Elements and Private Infrastructure. The applicant shall provide documents detailing the proposed ownership and maintenance structure of all common area and private infrastructure within a development. These documents shall be provided as part of the final subdivision development plan submission to the Planning Commission and must be approved by City Council.
(k) Duplication of Dwelling Materials, Color and Style. Substantial duplication of existing or planned exterior characteristics within a new development shall be prohibited. Those existing or planned exterior characteristics shall include, but not be limited to exterior materials, material colors and styles of a home for another adjacent lot shall not be permitted.
