Who decides where hens can live

The state law we read gives a named local body its own powers over where hens can live. What the checked sources say:

  • Inside a city, village or incorporated town, the municipality’s zoning ordinance supersedes any county zoning plan.
  • County zoning powers may not be used to impose regulations, eliminate uses or require permits for land used for agricultural purposes, which include animal and poultry husbandry, when agriculture is the principal activity on the land.
  • That limit does not cover parcels under 5 acres in counties of more than 400,000 people, or parcels under 5 acres from which $1,000 or less of agricultural products were sold in a calendar year in counties of 300,000 to 400,000 people or counties contiguous to one.

No statewide permission or prohibition on keeping chickens is established by this finding. Inside a city, village or incorporated town, its zoning ordinance supersedes county zoning, so check with your municipality. This page names the Counties Code, not municipal zoning powers or ordinances, and doesn't cover HOA, rooster or setback rules.

Registration: not established in the state sources we read.

The law's own words are quoted under state rules on keeping poultry below.

How to check: Look up the local rules where you live (the ordinances, bylaws or zoning of the body named here), or ask that office, before you get hens.

Housing-order finding as checked on 2026-10-24

The scope and conditions below are a dated record, not confirmation of today's position.

Not established from the sources checked

Uses housing orders in this scope: Not established from the sources checked.

Jurisdiction: Illinois

Applies to: Quarantine and movement-restriction powers of the Illinois Department of Agriculture under the Illinois Diseased Animals Act, which covers poultry, as published in an archived copy of the official statute page dated 11 June 2026.

Outside this finding's scope

  • A movement quarantine does not by itself establish a mandatory indoor-housing mechanism or an order currently in force.
  • The Act text comes from an archived copy dated 11 June 2026; later amendments were not checked.

What the checked sources say

  • Under the Act, animals include poultry, and a contagious or infectious disease is a specific disease the Department designates as contagious or infectious under its rules; whether avian influenza is so designated was not checked here. When the Illinois Department of Agriculture learns that animals are infected or suspected of being infected with a contagious or infectious disease, it may quarantine them. For a dangerously contagious or infectious disease, it orders the diseased and exposed animals and their premises quarantined, and it may issue area-wide quarantines on animals and premises.
  • With a quarantine, the Department may order that no diseased, contaminated or exposed animal be removed from the quarantined premises and that no susceptible animal be brought onto them, except under its rules.
  • Where conditions warrant, the Director may ask the Governor to proclaim a quarantine of an affected municipality or geographical district. The Director may also declare a temporary prohibition on the sale, movement or exhibition of certain types of animals for up to 30 days, extendable in increments of up to 30 days.
  • A quarantine stays in effect until removed by Department order.
  • As checked on 24 October 2026, the Department’s HPAI page carried a producer letter dated 14 October 2025 in which the state veterinarian strongly encouraged producers to move all birds indoors. That is a dated recommendation, not a mandatory housing order. Report unusual findings in domestic poultry immediately to the Department at 217-782-4944.
  • Current mandatory housing status remains unconfirmed.
