Full Breakdown
1(A)(8)(a) governs backyard sheds, workshops and other detached accessory buildings citywide. Any accessory structure set on a permanent foundation, or reaching 200 square feet or more of gross floor area, requires a building permit before construction under subsection (1). Subsection (2) then scales the maximum combined footage of all detached accessory buildings to lot size: on lots under one-half acre they cannot cover more than 30% of the rear yard, though a shed under 200 square feet on a corner lot may drop its side setback to 5 feet from the intersecting street's right-of-way if screened by a 6-foot opaque fence.
5% of lot size, whichever is greater. 5% of lot size, and every detached accessory building must sit at least 25 feet off the side and rear property lines. Lots of three acres or more may build up to 5% of the lot in accessory space, still with the 25-foot side and rear setback. 1(A)(7) separately requires at least 6 feet between a detached shed's walls and any dwelling or accessory building's walls, and 5 feet between eaves, unless a fire-resistive wall substitutes for the gap. No shed may be occupied or built before the main house is finished, under subsections (3) and (4).
Violations & Fines
Building without the required permit, exceeding the lot's percentage cap, or placing a shed closer than the code's wall and eave separation is a zoning violation under Article 18-4. Section 18-4-1-408 makes any violation punishable by the fine schedule elsewhere in the code, with each day of continued violation a separate offense chargeable to owners, tenants, contractors and anyone assisting in the unpermitted construction.
