§ 137-245. Height, area, and developmental regulations.

In the residential R-4 district, the height of buildings, the minimum dimensions of yards and setbacks, and the minimum lot area per detached single-family manufactured dwelling shall be as follows:

(1)

Height. No manufactured dwelling hereafter erected or structurally altered shall exceed 15 feet as measured from the finished grade.

(2)

Front building setback. There shall be a minimum front building setback of not less than 20 feet.

(3)

Side building setback.

a.

A side building setback shall not be less than five feet in width as measured from the facia board to the side lot line.

b.

On corner lots the usual front building setback and side building setback regulations shall apply. However, the exterior side building setback shall not be less than 50 percent of the front building setback required for lots facing the street upon which the side yard abuts. This regulation shall not be so interpreted as to reduce the buildable width of a corner lot of record at the front building setback required for lots facing the street upon which the side yard abuts. This regulation shall not be so interpreted as to reduce the buildable width of a corner lot of record at the time of the passage of this section to less than 25 feet, nor to prohibit the erection of an accessory building where this regulation cannot reasonably be complied with.

(4)

Rear building setback. There shall be a rear building setback of not less than 25 feet in depth. In the case of a through lot, no rear building setback is required, but each street frontage shall be subject to the front building setback requirements of this section.

b.

No accessory building shall be used in whole or part for living or residential purposes.

c.

No accessory building or accessory building area shall be used for commercial storage purposes.
