(a)

All accessory buildings and structures, including but not limited to decks, stairways, handicapped access, carports and breezeways, attached to the principal building on a lot shall be made structurally a part thereof and shall comply in all respects with the requirements of the development code applicable to the principal building.

All detached accessory buildings shall comply with all of the requirements applicable to the principal structure and maintain a minimum of ten feet between all structures.

No accessory building or structure shall be constructed, altered, or moved to any location within ten feet of the principal building unless the structure is made an integral part of the principal building.

(d)

In the R-1 through R-6 districts, the following maximum accessory structure size standards shall apply:

No maximum accessory structure size for lots larger than one acres in size, as long as impervious surface coverage isn't exceeded in the applicable zoning district. This standard shall only apply in R-1, R-2 and R-3 zoning districts.

(e)

No more than one accessory building (storage building) in excess of 200 square feet of floor area shall be allowed in the R-2, R-3, R-4, R-5 and R-6 districts except where the parcel is larger than one acre.
