Summary
Winnebago County allows home occupations in a dwelling or a small accessory building, but bans retail sales, outside employees, and a long list of trade-shop businesses.
A home occupation shall be conducted within a dwelling or within an accessory building that does not exceed five-hundred (500) square feet in area... No person, other than a resident of the dwelling, shall be employed in the conduct of a home occupation... There shall be no stock-in-trade other than products manufactured on the premises. Customary retail sales are prohibited.

Full Breakdown
Under the county's Unified Development Ordinance, a home occupation must be run inside the dwelling or an accessory building of 500 square feet or less, with overhead doors and main entrances kept closed to conceal the activity. Only a resident of the home may work in the business, no outside employees, and it can't start until the operator actually lives there. The county bars stock-in-trade beyond items made on site, outdoor storage or display, added traffic or on-street parking, and any nameplate sign bigger than 2 square feet. Contractor shops, landscapers, medical/dental clinics, bait shops, gun/ammo manufacturing, and vehicle or small-engine repair are flatly prohibited as home occupations, and a zoning permit is required that expires after three years.
Violations & Fines
Operating without the required zoning permit, exceeding the 500-sq-ft accessory building cap, or running a prohibited use (e.g., vehicle repair, contractor shop) can result in permit denial/revocation and code enforcement action under the UDO.
