Summary

Winnebago County keeps medical cannabis cultivation centers at least 2,500 feet from any pre-existing school, day care center, day care home or residential district under UDO § 15.3.16, more than double the 1,000-foot buffer set for dispensing organizations. Cultivation must also happen entirely inside a locked, enclosed facility, and operators must file a security and operations plan before the county approves siting.

These county ordinances apply to unincorporated areas of Winnebago County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Full Breakdown

16 sets the county's toughest cannabis buffer: no licensed medical cannabis cultivation center may sit within 2,500 feet of a pre-existing primary or secondary school, day care center, day care home, or residential district. The facility itself must be "an enclosed, locked facility, defined as a room, greenhouse, building, or other enclosed area equipped with locks or other security devices," accessible only to the registered cultivation center's or dispensing organization's own agents, and used solely to cultivate, store and distribute cannabis to registered qualifying patients.

As with dispensaries, the county defers to state law and any future amendment that tightens the standard automatically controls locally. An operator must submit an operation plan covering security measures, days and hours of operation, and a site plan describing exterior lighting and parking capacity. Article 24 defines a Medical Cannabis Cultivation Center as a facility "registered by the Illinois Department of Agriculture to perform necessary activities to provide only registered medical cannabis dispensing organizations with usable medical cannabis," confirming this section governs wholesale growing operations, not retail storefronts.

Cultivation centers are listed as a Special Use in the county's zoning tables, so a special use hearing is required on top of meeting the buffer and enclosure standards.

Violations & Fines

Siting or operating a cultivation center inside the 2,500-foot buffer, or without the required enclosed/locked facility and special use approval, is a Chapter 90 zoning violation enforced under § 4-4(j)(6): $75 for a first offense, $150 for a second, $350 for a third, and mandatory personal appearance before the hearing officer for a fourth or later offense.

Frequently Asked Questions

How far must a cannabis cultivation center be from a house in Winnebago County?
At least 2,500 feet from any pre-existing residential district under UDO § 15.3.16(A)(2), a wider setback than the 1,000-foot rule that applies to dispensing organizations elsewhere in the same Article.
Does a cultivation center have to be indoors?
Yes. Section 15.3.16(A)(1) requires the operation to occur inside an enclosed, locked room, greenhouse or building equipped with security devices limiting access to the licensed center's own registered agents.
Is a cultivation center allowed by right in any zoning district?
No. It is listed as a Special Use, meaning the operator must go through the county's special use permit hearing in addition to meeting the 2,500-foot buffer and enclosed-facility standards of § 15.3.16.
What agency licenses a cannabis cultivation center in Illinois?
The Illinois Department of Agriculture registers cultivation centers, per the definition adopted into Winnebago County's own zoning ordinance; county approval is layered on top of that state registration, not a substitute for it.
