Summary
A shed under 36 square feet skips Racine County's zoning permit, but every accessory building on a lot counts toward an aggregate footprint cap, from 720 square feet on small lots up to a percentage of acreage on larger ones.
any detached accessory structure less than thirty-six (36) square feet in area is exempt from the requirement for obtaining a zoning permit... The aggregate total footprint area for all accessory structures shall not exceed the following square footage for the stated lot size... < 10,000 square feet lot = 720 square feet... ≥ 10 acre lot = five (5) percent of lot area.

Full Breakdown
Sec. 20-1115(a) exempts any detached accessory structure smaller than 36 square feet from needing a zoning permit; anything larger needs one from the zoning administrator. Sec. 20-1115(c) then caps the combined footprint of all accessory structures on a lot: 720 square feet on lots under 10,000 square feet, rising through fixed figures to 4 percent of lot area on 5-to-10-acre lots and 5 percent on lots of 10 acres or more. A conditional-use permit or site plan review can allow more square footage when the extra building is integral to an approved use. This governs unincorporated towns that adopted county zoning, not the City of Racine or its incorporated villages.
Violations & Fines
Exceeding the lot's aggregate footprint cap or skipping the required permit for a shed over 36 square feet voids any permit issued under Sec. 20-84 and can draw a removal order.
