Keeping Farm Animals as Pets in Illinois: Zoning, Permits, and Local Rules Explained

Illinois has a long agricultural tradition, and more residents than ever are bringing that tradition closer to home by keeping chickens, goats, miniature pigs, and other farm animals as pets. Whether you live on a rural acreage in Sangamon County or a suburban lot in the Chicago collar counties, the rules governing farm animal ownership can vary dramatically depending on where your property sits.

There is no single statewide law that says you can or cannot keep a farm animal as a pet in Illinois. Instead, the legal framework is built from layers — state statutes, county zoning codes, municipal ordinances, and in some cases HOA rules — each of which can expand or restrict what the layer above it allows. Understanding how those layers work together is the first step before you ever bring an animal home.

Pro Tip: Always verify rules at the municipal and county level before purchasing any farm animal. State law sets a baseline, but your city or township ordinance is almost always the controlling authority for residential properties.

Which Farm Animals Can You Keep as Pets in Illinois

Illinois does not maintain a statewide list of farm animals that are explicitly approved or banned for residential pet ownership. What the state does regulate, however, is a category of animals that nobody may keep: dangerous animals and primates. Illinois structures its exotic animal law as a general prohibition — it is illegal for any person to keep, harbor, or have in their care any animal classified as a dangerous animal or a primate, and these animals may only be kept in properly maintained zoological parks, federally licensed exhibits, circuses, scientific institutions, and research laboratories.

Outside that prohibition, common farm animals kept as pets in Illinois include chickens (hens), ducks, rabbits, goats, miniature pigs, sheep, and horses. Each of these falls under local jurisdiction rather than a statewide permit scheme. The Illinois Domestic Animals Running at Large Act (510 ILCS 55) defines “livestock” to include bison, cattle, swine, sheep, goats, equidae, camelids, ratites, and fowl — a definition relevant to confinement and liability rules, not to whether you may keep them as pets.

Practically speaking, the animals most commonly approved for residential pet ownership across Illinois municipalities are backyard chickens (hens only), dwarf or Nigerian Dwarf goats, rabbits, and miniature pigs. Larger livestock — horses, cattle, full-size pigs — are generally restricted to agricultural or large-lot residential zones. You can explore a broader overview of farm animals to understand which species are most commonly kept in domestic settings before narrowing your focus to what Illinois law allows near your address.

Key Insight: Rabbits occupy an interesting legal middle ground in Illinois — many ordinances treat them as domestic pets rather than farm animals, which can make them easier to keep in standard residential zones where chickens or goats would require a permit or be outright banned.

Zoning and Property Requirements in Illinois

Zoning is one of the primary tools Illinois municipalities use to regulate how many and what kinds of animals can be kept on a property. The zone your home sits in — residential, agricultural, or mixed-use — often determines not just whether you can keep certain animals, but how many.

Agricultural (A) zones are the most permissive. Properties zoned A-1 or AG in most Illinois counties can keep horses, cattle, swine, goats, sheep, and poultry without special permits, subject to minimum lot sizes and setback rules. Standard residential zones — R-1, R-2, and similar designations — are far more restrictive and typically limit farm animal keeping to small poultry or dwarf breeds, if they allow it at all.

A household in an unincorporated rural county may face no numeric limit at all, while a household in a dense suburb may be capped at three or four animals. Conditional use permits are common — they allow a use in a zone that does not automatically permit it, subject to a public hearing and approval by the local zoning board. If your current zoning does not allow the animal you want, a conditional use permit or variance may be your only legal path forward.

Unincorporated areas of a county fall under county zoning authority rather than any city’s rules. Once a parcel is annexed into a municipality, city ordinances take over. This distinction matters enormously: the same half-acre lot may be perfectly legal for a small goat herd if it sits just outside city limits, and completely prohibited if it sits inside them.

Lot Size and Number Limits for Farm Animals in Illinois

The type and number of animals you may keep on your property depends on the property’s zoning district and lot size. Illinois counties and municipalities each set their own thresholds, so the numbers below represent real examples from actual local codes rather than statewide rules.

Animal Type	Example Jurisdiction	Minimum Lot Size	Number Limit
Hens (chickens)	Des Plaines	R-1 residential lot	Up to 6 hens; no roosters
Hens (chickens)	Tinley Park	Standard residential lot	Up to 4 hens; no roosters
Hens (chickens)	North Barrington (R-1)	40,000 sq. ft. or greater	Up to 6 hens
Goats, sheep, cattle	North Barrington (R-1)	Minimum 3 acres	3 animals per 5 acres; max 6
Horses, donkeys, mules	North Barrington (R-1)	Minimum 3 acres	3 per 5 acres; max 6
Goats, chickens, honey bees	Madison County (unincorporated)	Varies by zoning district	Set by district classification

In North Barrington, horses, donkeys, and mules are not permitted as an accessory use except in the R-1 District, and are not permitted in the R-1 District if the tract consists of less than three acres. In the R-1 District, not more than three such animals shall be permitted for each five acres, with the total not to exceed six animals.

Sheep, goats, and cattle are similarly restricted — permitted only in the R-1 District when maintained as pets of children under 18 years of age, and not permitted if the parcel is less than three acres. In the R-1 District, not more than three sheep, goats, or cattle shall be permitted for each five acres of land, with the total not to exceed six animals.

Most residential areas allow hens, but roosters are often restricted or banned due to noise. In many major Illinois cities, the hen limit in standard residential zones falls between four and ten birds. Roosters are banned or heavily restricted in almost every Illinois city and residential zone due to noise ordinances and neighbor complaints.

Permit and Registration Requirements in Illinois

Illinois has no statewide permit required to keep farm animals as pets on private property. The Illinois Department of Agriculture’s Bureau of Animal Health and Welfare has statutory authority to license and inspect pet shop operators, dog dealers, kennel operators, cat and dog breeders, animal control facilities, animal shelters, and horse rescues — facilities defined in the Illinois Animal Welfare Act, 225 ILCS 605. Private pet ownership of farm animals falls outside that licensing framework at the state level.

At the local level, however, permits are common and sometimes mandatory. In Champaign, residents must first obtain a coop license before keeping hens. Before a license is approved, applicants may need to meet building code requirements and notify neighbors to ensure compliance.

Des Plaines allows backyard hens, but under strict rules and with a permit. Residents may keep up to six hens, but roosters are prohibited. The applicant must also provide a courtesy notice, at least two weeks prior to the date of application, to the owners of adjoining property stating the applicant’s intention to apply for a permit to keep hens.

Tinley Park allows residents to keep up to four hens with a poultry license, but roosters are not permitted. Coops must be under 24 square feet, no taller than six feet, and placed in the rear yard at least 10 feet from property lines and 75 feet from schools, streets, or neighboring homes. Runs must be enclosed and predator-proof, and a building permit is required for any coop or enclosure.

For beekeeping — another popular form of farm animal keeping in Illinois — a separate permit and registration framework applies under the Illinois Bees and Apiaries Act (510 ILCS 20). Our detailed breakdown of beekeeping laws in Illinois covers registration, hive placement rules, and county-level requirements specific to that species.

Important Note: Even if a permit is not required in your jurisdiction, you may still need to pull a building permit for any coop, pen, or enclosure you construct. Check with your local building department separately from your animal control or zoning office.

Housing, Setback, and Sanitation Rules in Illinois

Physical infrastructure rules — where structures must be placed, how large they can be, and how they must be maintained — are as important as the permit itself. Violating a setback or sanitation rule can result in permit revocation even if you obtained proper approval to keep the animals.

In Des Plaines, coops and enclosures must not be visible from the street, must be located in a fenced rear yard, and must comply with all applicable setback requirements. A permanent fence structure must fully enclose the rear yard containing the coop and enclosure. If the rear yard of a property requesting a hen permit is not already enclosed with a permanent fence, the property owner must obtain a fence permit from the city and install the fence prior to keeping chickens on the property.

In North Barrington, no horses, donkeys, mules, sheep, goats, or cattle shall be housed or grazed within 200 feet of an adjacent property owner’s dwelling. This 200-foot setback from neighboring structures is a common benchmark across Illinois municipalities for larger livestock, though exact distances vary by jurisdiction and animal species.

In Decatur, it is unlawful to keep chickens, ducks, rabbits, or other domestic fowl unless they are in an enclosure that is at least 75 feet from any dwelling other than the owner’s, and the enclosure cannot be placed in the front or side yard.

Sanitation standards apply universally. Coops and enclosures shall be maintained in clean and sanitary condition at all times. Most Illinois ordinances require that manure be removed regularly, feed be stored in sealed containers to prevent rodent attraction, and standing water be eliminated to reduce mosquito breeding. Failure to meet sanitation standards is one of the most common grounds for nuisance complaints and permit revocation.

County and City Ordinances That May Override State Rules in Illinois

One of the most important things to understand about farm animal law in Illinois is that local ordinances routinely go further than state law — and that is entirely legal. Laws differ between cities, some adhering solely to Article 6 of a county public health ordinance, and others outlining their own regulations, which makes communication and education between agencies necessary.

The variation across Illinois is striking. Bolingbrook does not allow backyard chickens. According to the Bolingbrook village code, no goat pen, chicken coop, runway, yard, or other place for the keeping of any goat, chicken, pigeon, goose, turkey, mule, donkey, sheep, bovine, swine, or other such animal or fowl shall be maintained within the village. Residents cannot keep backyard chickens for personal use within the Bolingbrook city limits.

Joliet does not permit backyard chickens either. According to Joliet’s planning and zoning rules, unless your property is classified as a farm, you cannot keep farm animals, including fowl such as chickens, within city limits. By contrast, Springfield does allow backyard chickens with some restrictions. Residents may keep hens as long as they are properly fenced in, though roosters are not permitted. Chickens are prohibited in Zone E, which means they can be kept in other zones as long as local requirements are followed.

In McHenry, except as authorized by the issuance of a conditional use permit in the A-M Agricultural and Mining Overlay District, no person shall keep or harbor any farm animals within the corporate limits of the city, including chickens sold as “household pets.” That last detail — the explicit mention of chickens marketed as household pets — shows how seriously some municipalities take the distinction between pet and livestock classification.

Madison County takes a tiered approach in its unincorporated areas. Domestic farm animals are defined as small farm animals that have historically coexisted in urban and suburban settings, and for the purposes of the Madison County ordinance, this definition includes only goats, chickens (hens only), and honey bees. Animals that do not fit that narrower definition fall under the broader “farm animal” category, which carries more restrictive zoning requirements.

HOA rules add yet another layer. Many associations limit the number, types, and breeds of pets residents can keep. An HOA might allow dogs, cats, and fish, but prohibit exotic animals such as ferrets, sugar gliders, and hedgehogs — and the same logic applies to farm animals. An HOA can prohibit chickens or goats even in a city where the municipal code permits them. Always check your CC&Rs before purchasing any farm animal.

Common Mistake: Assuming that because your neighbor keeps chickens, you can too. Your neighbor may be in a different zoning district, may have a grandfathered permit, or may simply be out of compliance. Always verify the rules for your specific parcel — not the parcel next door.

Right-to-Farm Laws and How They Apply to Pet Farm Animals in Illinois

Illinois has a Right to Farm Act, codified under the Illinois Compiled Statutes. The law is designed to protect established agricultural operations from nuisance lawsuits brought by neighbors — particularly neighbors who move near a farm and then complain about odors, noise, or dust that are normal byproducts of farming. The Illinois Livestock Management Facilities Act (510 ILCS 77) and related statutes provide a legal shield for qualifying operations.

The critical question for pet farm animal owners is whether those protections extend to a backyard goat or a small flock of hens on a residential lot. The short answer is: generally no, not in the way they apply to commercial or established agricultural operations. Illinois Right to Farm protections are designed for bona fide agricultural uses — operations that predate nearby residential development and are conducted in conformance with good agricultural practices. A few chickens kept as pets in a suburban backyard are unlikely to meet that threshold.

That said, the Right to Farm framework does have indirect relevance. If you live in an unincorporated rural area and your property is used for genuine agricultural purposes — even small-scale ones — the law can offer some protection against nuisance claims from newer neighbors. The Illinois Department of Agriculture’s Code of Country Living guidance addresses the realities of living in the countryside and acknowledges that some conflicts between rural agricultural uses and newer residential development are inevitable. The guidance encourages prospective rural buyers to investigate existing agricultural practices before purchasing property.

For pet farm animal owners in suburban or urban settings, the more practical protection comes from your local zoning approval or permit. If you obtained a valid permit, complied with all setback and sanitation rules, and your animals are not creating a legally actionable nuisance, your permit itself provides a measure of legal standing. If the permit holder is found to be in violation, the City Manager may revoke the permit — which means maintaining full compliance is your best long-term protection against neighbor complaints and enforcement action.

It is also worth noting that Illinois nuisance law cuts both ways. While Right to Farm protections may not cover a backyard flock in a residential zone, a neighbor cannot use nuisance law to shut down a lawfully permitted and properly maintained animal operation simply because they dislike it. The animals must actually create a legally cognizable nuisance — unreasonable interference with the use and enjoyment of neighboring property — for a complaint to succeed in court.

Pro Tip: If you want the strongest possible legal footing for keeping farm animals on your property, document your permit, your compliance with all setback and sanitation rules, and any neighbor communications. This paper trail is your best defense if a nuisance complaint is ever filed against you.

Keeping farm animals as pets in Illinois is genuinely achievable for many residents, but it requires doing your homework at the local level first. State law sets only the broadest guardrails. Your county zoning code, your municipal ordinance, and potentially your HOA rules are the documents that will actually determine what you can keep, how many, where you can house them, and what permits you need to obtain. Check those sources in that order before you commit to any animal.
