§ 62-1959. Zero lot line subdivisions.

(a)

Purpose and intent. The purpose of a zero lot line subdivision is to permit an optional zoning alternative to provide for subdivision design flexibility, while maintaining the integrity of the single-family detached lifestyle. This zero lot line subdivision design allows a single-family structure to be placed on one side property line, thereby maximizing the utilization of land and individual lots in new subdivisions meeting the requirements of this section.

(b)

Minimum development area. For a conditional use permit to be granted, the proposal shall have a minimum development area of five acres, and the concept plan shall show that all required rights-of-way, easements, streets, roads and other public facilities have been provided for within the minimum development area.

(c)

Design standards.

(1)

Minimum lot size, width and coverage. The following minimum lot sizes and widths and maximum structural lot coverage shall apply in each zoning classification as noted in this subsection for a zero lot line conditional use permit:

Zoning Classification	Minimum Lot Size (square feet)	Minimum Lot Width (feet)	Maximum Structural Lot Coverage (percent)
RU-1-7	5,000	50	45
RU-1-9	5,500	55	40
RU-1-11, RU-1-13	6,000	60	35

 

(2)

Minimum setback and distance between structures.

a.

Setbacks for principal structures. Setbacks for principal structures are as follows:

1.

The front setback shall be 15 feet.

2.

The rear setback shall be 20 feet.

3.

There shall be no minimum setback on one side and a setback of ten feet on the opposite side. The zero side yard shall not be adjacent to a public right-of-way or private street. No footer or structure shall be located on or beyond the side yard property line, nor shall the zero side yard setback exceed three feet so as to be consistent with the building envelope requirements of this section.

b.

Setbacks for detached accessory structures. Setbacks for detached accessory structures are as follows:

1.

The front setback shall be equal to the front building line.

2.

The rear setback shall be ten feet for garages and all accessory structures between 200 and 400 square feet in size, and five feet for accessory structures less than 200 square feet in size.

3.

The side setback shall be five feet.

c.

Distance between structures. A distance of ten feet shall be maintained between the detached principal structures. Fences, patios and other similar yard accessories shall not be located closer than five feet to a principal structure on an adjacent lot.

(3)

Building envelope. A building envelope shall be established for each lot and shown on a plat for recording in the public records. All structures shall be constructed within the building envelope. No appurtenances shall extend beyond the perimeter of a building envelope. No windows, doors, air conditioning units or other openings or accessories shall be permitted within the zero side yard, and no portion of a structure, including appurtenances, shall project over or across any property line.

(4)

Maintenance access easement. Utilization of a zero side lot line shall require the existence of a maintenance access corridor along the zero side lot line, which corridor shall be at least five feet in width. That portion of the maintenance access corridor which lies on the adjacent property shall be established and maintained through a maintenance access easement encumbering the adjacent property and in favor of the property utilizing a zero side lot line. The maintenance access easement shall be perpetual and run with the land, and the plat shall indicate to which lot the maintenance access easement is assigned.

(5)

Detached accessory structures. Detached accessory structures shall not exceed 400 square feet in size, and shall comply with all setback requirements as stated in this section.

(d)

Development standards.

(1)

Application. In addition to the requirements of section 62-1151 regarding application requirements for amendments to the zoning map, the application under this section shall include the submission of a binding concept plan. The binding concept plan shall be drawn at a scale of no less than one inch equals 50 feet. Lot locations and dimensions with building envelope locations and dimensions shall be shown on the concept plan, as well as other graphics deemed necessary by the zoning official or his authorized agent.

(2)

Final plat. Development of a zero lot line subdivision shall be in accordance with article VII of this chapter, and no building permit shall be issued for any lot within a zero lot line subdivision until the final plat has been approved by the board of county commissioners and duly recorded in the public records of the county. The plat shall identify all building envelopes and shall contain a note with the following language: "This is a zero lot line subdivision and all structures shall be constructed within the building envelopes as designated on this plat. No appurtenances shall extend beyond the perimeter of any building envelope, and no portion of any structure, including appurtenances, shall project over or across any property line."
