This applies inside Sun Prairie city limits. ZIP codes and mailing addresses can cross city lines, and nearby towns, villages, and counties have their own rules. HOA rules and leases can be stricter.
Before you apply
- Register the premises with the Wisconsin DATCP Livestock Premises Registration program (free) and save your registration card.
- Apply for and obtain a Special Use Permit ($35) from the Planning Department with a scaled site plan and coop/enclosure elevation plan before building the coop.
- After Special Use Permit approval, apply online through OpenGov for the City Clerk Chicken-Keeping License.
Key rules
- Allowed on single-family residential lots with a single dwelling unit (and at schools under a Conditional Use Permit).
- Covered coop and fenced enclosure must be in the rear yard, set back at least 15 feet from all property lines, and placed on a paved surface or raised at least 24 inches off the ground.
- Combined coop and enclosure area must provide at least 16 square feet per chicken and not exceed 120 square feet total; the coop structure itself cannot exceed 50 square feet or 12 feet in height (coops over 80 sq ft total require a building permit).
- Chickens may range in the rear yard outside the enclosure only if the entire rear yard is enclosed by a 6-foot-high fence and hens are returned to the coop nightly.
- Feed must be stored outside the coop/enclosure in rodent-proof containers, waste must be bagged and placed in city refuse carts, and on-site slaughtering is prohibited.
