(A) Buildings to be on a lot. Except as permitted in the “PD” (Planned Development) District, every building shall be located on a lot. In the neighborhood zoning districts, no more than one principal building is permitted on a lot unless otherwise provided in the applicable zoning district regulations.
(B) Compliance with zoning district regulations. The size, width, depth, shape and orientation of lots shall comply with the applicable zoning district regulations.
(C) Frontage. All lots shall front on a public or private street and shall have a minimum frontage width as indicated in the zoning district regulations. On irregularly shaped lots, a minimum street frontage of 15 feet is required. An “irregularly shaped lot” includes any lot located on a cul- de-sac or abutting a curved section of a roadway with a centerline radius of less than 200 feet.
(D) Front and side setbacks.
(1) Designation. Front and side setbacks adjacent to streets shall be shown on all plats as required by Divisions 3 and 4 of this chapter. A subdivider may elect to impose greater setbacks through restrictive covenants. The city shall only enforce the setbacks required by Divisions 3 and 4 of this chapter.
(2) Side yard building line. The building line for an existing residence having a side yard of three or more feet may be maintained on any addition to the residence, but in no instance shall the side yard be less than three feet.
(3) Yards adjacent to rights-of-way and easements. On lots that abut a public alley, railroad right-of-way or a utility/drainage right-of-way or easement that is not part of a platted lot, one-half of such alley, right-of-way or easement, up to a maximum of 15 feet, may be considered as part of the minimum required rear or side yard.
(4) Variation in front yard. In any block in which 70% of the lots have front yards that are less than required by the existing zoning regulations, construction on any remaining vacant lots is permitted to the average yard of the existing improved lots.
(5) Rear yards on irregular lots.
(a) For lots fronting on cul-de-sacs, eyebrows or elbows, and other irregularly shaped lots, a rear yard of 15 feet is permitted based on the mean horizontal distance of the principal structure from the rear lot line; provided that, no part of the structure is closer than ten feet to the lot line.
(b) The mean horizontal distance shall be calculated by adding the products of the width of each segment of the principal structure multiplied by its average distance from the property line and then dividing this sum by the total width of the structure.
(6) Dwelling on small lot. A platted lot within a residential district that contains less than the minimum area for the district may be used for a single-family dwelling, provided that the lot is held in separate and different ownership from any immediately abutting lot, has a minimum area of 3,500 square feet, and has a minimum street frontage of 20 feet.
(E) Corner lots.
(1) Corner lots shall have two front setbacks and two side setbacks.
(2) For corner lots, the side having the shortest street frontage is considered the front for setback purposes. The Code Enforcement Officer may waive this requirement and determine the front yard to be on the street front that is in line with the prevailing pattern of front yards on the street in order to be consistent with the established pattern of the street.
(F) Double frontage lots. Double frontage or through lots are prohibited, except in commercial or industrial districts.
(G) Setback encroachments. The features designated in Table 153.0996(A) below may encroach into a required yard as indicated in the table. The accessory structures shown in Table 153.0996(A) below are permitted in the locations indicated.
(H) Vehicle and pedestrian areas for single-family, duplex, triplex and quadraplex lots.
(1) Generally. Restrictions on driveway areas are designed to avoid the domination of front yards by large expanses of impervious surfaces, which deaden the streetscape and discourage pedestrian activity. Reducing the width of driveways can reduce total site imperviousness.
(2) Applicability. This section applies to any subdivision plat, site plan or development approval authorizing a single-family, duplex, triplex or quadraplex structure.

(3) Alleys. If the site is served by an alley, access for motor vehicles must be from the alley and not from a street frontage.
(4) Location. Parking areas may not be located in the front setback. Parking may be provided in the rear yard, and access may be provided through alleys where the front yard is insufficient to accommodate a driveway.
(5) Vehicle areas between the porch and the street. Vehicle areas may not be located between the building’s porch or porches and an adjacent street.
(6) Walkways. A walkway shall extend from the sidewalk or street to the main entrance. The walkway shall be at least two feet, but not more than five feet in width.
(7) Driveways.
(a) 1. Driveways and other impervious surfaces shall not comprise more than the percentage of the front yard as specified in Column (B) of Table 153.0996(B) below for the zoning districts or use patterns designated in Column (A) of the same table.
2. Driveways shall not exceed the width established in Column (C) of Table 153.0996(B) below.
3. Parking may be provided in the rear yard, and access may be provided through alleys where the front yard is insufficient to accommodate a driveway.
4. Table 153.0996(B) below does not apply to irregularly shaped lots as defined by §§ 153.1105 through 153.1110 of this chapter.
(b) In order to reduce run-off and increase storm water travel times, alternative materials for driveway surfaces, such as pervious pavers or gravel, is permitted in any residential zoning district.
(I) Flag lots.
(1) No more than the number of flag lots shown in Table 153.0996(C) below may be authorized, allowing for the more efficient use of irregularly shaped parcels of land, sites with physical limitations, or where the integrated nature of multiple buildings on a site dictates the need for such lots. Flag lots are not permitted where they will increase the number of lots accessing collector or arterial streets.
(2) The minimum driveway width for a flag lot is nine feet.
(3) (a) The minimum frontage at the right-of-way line for any flag lot shall be equal to the minimum required driveway width, plus four feet.
(b) The flagpole portion of the lot shall not be considered in determining the area of the lot.

(J) Reduction of lot size by governmental action. Where the owner of a legally platted lot or successor in title has a lot reduced in size as a result of governmental action, and does not own sufficient land to enable the lot to conform to the dimensional requirements of this chapter, such lot may be used as a building site for a single-family residence or other non-residential use permitted in the district in which the lot is located; provided that:
(1) Where the lot area or mean lot width is reduced by governmental action by less than 20% of the minimum specified in this chapter, the Code Official shall issue a development approval or certificate of occupancy; and
(2) In those cases where the lot area or mean lot width is reduced by governmental action by more than 20%, the Code Enforcement Officer may approve as a building site a dimension that conforms as closely as possible to the required dimensions of this chapter; provided that, the combined area of the principal building and accessory buildings shall not cover more than 40% of the lot area remaining after governmental action.
