(A) Accessory buildings shall not be permitted prior to the erection of the principal building, except for storage purposes and not for human occupancy.
(B) No detached accessory building shall be located closer to a side lot line than five feet.
(C) The normal maximum height permitted shall be 18 feet or one and one-half stories.
(D) The height of accessory buildings may be increased to 25 feet or two stories, provided the minimum required five-foot distance from side lot lines is increased one foot for each two feet above the normal maximum height permitted, upon the granting of a special use by the Board of Zoning Appeals. Following are special use considerations which can be granted by the Board of Zoning Appeals:
(1) Where 25% or more of the lots in a block are occupied by buildings, the average setback of such buildings determines the dimensions of the front yard in the block, but the maximum front yard need not exceed the minimum requirement of the district regulation;
(2) Front yard or setback lines established in recorded subdivisions establish the dimensions of front yards in such blocks, except when such setback lines may be less restrictive, as provided in § 154.002; and
(3) On lots extending through from one street to another, a front yard is required on each street.
(a) Tapered yard. Where a reversed interior lot abuts a corner lot, or on an alley separating such lots, any accessory building located on the rear lot line of a corner lot shall set back from the side street as far as the dwelling on the reserved interior lot; for each foot that such accessory building is placed from the rear line towards the front line of the corner lot, the accessory building may be set four inches closer to the side street line, but in no case closer than five feet.
(b) Maximum height. The normal maximum height of structures may be increased, upon approval of the Board of Zoning Appeals, as follows.
1. Buildings may be erected higher than the normal maximum if they are set back, from front and rear property lines, one foot for each two feet of additional height above the normal maximum height.
2. Chimneys, cooling towers, elevator bulkheads, fire towers, penthouses, stacks, tanks, water towers, transmission towers, or essential mechanical appurtenances may be erected to any height not prohibited by other laws or ordinances.
