Summary
Cook County has no separate agricultural zoning district, but its R-1 Single-Family Residence District, the county's largest-lot residential category, is expressly designed, per Zoning Ordinance § 4.1.1, to allow "a mixture of agricultural uses and homes," and § 4.1.3.F lists agricultural uses, greenhouses and nurseries as permitted, by-right uses on R-1 lots.

All commercial activities are prohibited, except for selected recreation and sanitary uses. ...

Full Breakdown

Violations & Fines
Converting R-1 land to a use not enumerated in §§ 4.1.3 through 4.1.6, including ordinary commercial uses the district's description expressly excludes, is prohibited outright under § 4.1.7 ("All uses not expressly authorized... are prohibited") and can draw a cease-and-desist order from the Department of Building and Zoning, forcing the landowner either to stop the use or apply for a variance or special use permit.
