Oak Hill City Zoning Code

Sec. 14-121

Bulk, yard, and density regulations.

The regulations appearing below apply to lots and buildings or other structures located on any lot or portion of a lot including all new development, enlargements, extensions, or conversions. Existing buildings or other structures which do not comply with one (1) or more of the applicable bulk regulations are classified as nonconforming and are subject to the provisions of regulations governing nonconforming uses, buildings, or structures and lots.

(a)

Minimum lot area. Within all residential districts, the minimum size lot and width of lot used for residential purposes shall be as established in Table II.

(b)

Maximum lot coverage. Within all residential districts, the maximum lot coverage by all buildings and impervious surfaces shall not exceed the greater of the percentage of lot area or square footage as established in Table II.

(c)

Maximum permitted height. No building shall exceed the height requirements as determined in Table II.

(d)

Density regulations. The maximum residential density permitted on any zone lot shall be controlled by the lot area per dwelling as established in Table II.

(e)

Yard requirements. Within all residential districts, the minimum yard requirements established in Table II shall apply.

(f)

Minimum front yard setback. The front yard setback shall be determined by the average setbacks of four (4) lots, which are most adjacent with like-facing homes thereon. If such average is not capable of being determined due to lack of development on adjacent lots or is otherwise impractical due to site conditions affecting adjacent lots, then the minimum front yard setback is as set forth in Table II.

(g)

Lot depth and lot width requirements. The minimum front lot line and the lot width to depth ratio are listed in Table II of the code. The minimum lot frontage requirements vary between fifty (50) feet and two hundred twenty-five (225) based upon the minimum lot sizes. The intent of these minimums is to complement the lot width to depth ratios. For example, a lot with a minimum area of ten thousand (10,000) square feet would have a minimum lot frontage of fifty (50) feet, and thereby have a maximum depth two hundred (200) feet to achieve the minimum lot area based upon the 4:1 depth to width ratio.

(h)

Lot area. "Lot area" means the horizontal area included within the boundar lines of a lot, typically stated in terms of acreage or square feet.

(i)

Street frontage. The minimum street frontage as set forth in Table II, except for cul-de-sac streets which shall have not less than forty (40.)

(j)

Minimum rear yard setback. The minimum rear setback is as set forth in Table II.

(k)

Minimum side setback. The minimum side setback from a property line of an adjoining lot or a side street is as set forth in Table II.

(l)

Side set back. Side Street as set forth in Table II.
