Summary
Farming inside the City of Sun Prairie is zoned, not banned. Cultivation, husbandry and intensive agriculture are regulated land uses under Title 17 Zoning. On any buildable lot, cultivation cannot exceed twenty percent of the lot area, and animal husbandry in the RH-35ac Rural Holding district needs a special-use permit with a three-hundred-foot setback from residential property.

Full Breakdown
080 of the Sun Prairie Code of Ordinances splits agricultural land use into three tiers. 040. Husbandry, keeping animals at less than one animal unit per acre, is a special use only in the RH-35ac Rural Holding district: any building housing animals must sit at least three hundred feet from residentially zoned land and one hundred feet from every other lot line, with outdoor animal pens set back at least ten feet from residential property. Intensive agriculture, feedlots, hog farms, poultry operations and similar high-density operations, requires a conditional use permit and is confined to the RH-35ac district as well.
The RH-35ac Rural Holding district itself sits at the edge of the city, reserved for very low-density development so that farmland is not forced out by suburban lot sizes before urban services reach it. 140, not under this section. Because the City of Sun Prairie is incorporated, Dane County's zoning authority under Wis. 69 stops at the city line; Title 17, adopted under the state's city zoning enabling statute, Wis. 23, is what actually governs.
Violations & Fines
Operating a husbandry or intensive agriculture use without the required special-use or conditional-use permit, or outside the RH-35ac district where the code confines it, is a zoning violation enforced by the Zoning Administrator under Chapter 17.48, Administration and Enforcement. Exceeding the twenty-percent cultivation cap or placing animal buildings inside the three-hundred-foot residential setback triggers a stop-work or correction order, and unresolved violations can be cited as municipal ordinance violations carrying forfeitures set by the common council.
