Can You Have Pets in Condos in Illinois? What the Law Really Says
September 8, 2026
Buying a condo in Illinois does not automatically give you the right to keep a dog, cat, or any other pet inside it. Whether you can have pets in condos in Illinois depends almost entirely on what your specific building’s governing documents say, not on any statewide statute protecting pet owners. That surprises a lot of buyers who assume pet ownership is a given once they own their unit outright.
Illinois is not one of the handful of states that guarantees condo owners the right to keep at least one pet. Instead, your board’s declaration, bylaws, and rules fill in nearly every detail, from whether pets are allowed at all to how many pounds your dog can weigh. Below is what actually controls the answer, where state and federal law step in, and what your options look like if your board’s pet policy does not work for you.
Can a Condo or HOA Ban Pets in Illinois
Yes. An Illinois condo association or HOA can legally prohibit pets entirely, and many buildings do exactly that. Industry research on state HOA laws confirms that there are no Illinois HOA pet laws that regulate how a HOA can enforce pet policies in its community. That puts Illinois in a very different position than California, where no governing documents shall prohibit the owner of a separate interest within a common interest development from keeping at least one pet, subject to reasonable rules and regulations of the association. Illinois has no equivalent guarantee.
Attorneys who represent Illinois community associations confirm this directly. Not all condominiums and common interest communities permit owners to have pets, and in fact, some community associations have no pet policies in place. When boards do allow pets, courts generally defer to the association’s authority to set the terms. Courts throughout the country have consistently upheld the right of HOAs to impose architectural restrictions as long as the restriction serves a legitimate purpose, is within the association’s power under state law and/or the community’s declaration, and does not violate any other law or public policy.
Most pet disputes in Illinois condos revolve around the two most common companion species — the domestic dog (Canis lupus familiaris) and the domestic cat (Felis catus) — but the same board authority applies to birds, reptiles, and anything else an owner might want to keep. Before you assume your building is pet-friendly, ask for the current declaration and rules in writing.
Important Note: A listing agent telling you a building is “pet-friendly” is not a substitute for reading the actual declaration and rules and regulations. Verbal assurances are not enforceable against the association.
What Illinois Law Says About Pet Restrictions
No single Illinois statute sets statewide rules for pet ownership in condos. The two main laws governing associations, the Illinois Condominium Property Act and the Common Interest Community Association Act, address governance, assessments, and records. Neither one dictates whether pets are allowed or how many a unit owner can keep, which is why enforcement and recordkeeping duties under 765 ILCS 605/19 of the Condominium Act and 765 ILCS 160/1-30 of the Common Interest Association Act leave pet policy entirely to each association’s own documents.
The one Illinois law that speaks directly to animals in condos is narrower than most owners expect. The Illinois Assistance Animal Integrity Act, 310 ILCS 120/1, et seq., provides guidelines to help condominium associations and other housing providers who receive a request for an exception to a policy prohibiting or restricting animals due to a disability-related need for an assistance animal. That law only governs disability accommodation requests. It does not create a general right to own a pet.
Outside your building, local government adds another layer. No statewide pet limit applies in Illinois — your city, county, HOA, or landlord sets the rules. Associations can also stack their own limits on top of whatever the municipality allows: owners and landlords of multiunit housing structures or condominium associations may further limit the number of animals in said structures and units, meaning a landlord can set the pet limit at one, zero, or any other number, and that limit applies regardless of what the local ordinance allows. For a broader look at how municipal caps interact with private rules, see this breakdown of local pet limits across Illinois.
| Illinois Law | What It Actually Covers |
|---|---|
| Illinois Condominium Property Act (765 ILCS 605) | Association governance, budgets, and records — not pet policy |
| Common Interest Community Association Act (765 ILCS 160) | HOA governance for non-condo common interest communities |
| Illinois Assistance Animal Integrity Act (310 ILCS 120) | Disability accommodation requests for service and support animals only |
| Fair Housing Act / Illinois Human Rights Act | Federal and state disability discrimination protections tied to assistance animals |
What Your Governing Documents (CC&Rs/Bylaws) Control
Since state law stays quiet on pets, your association’s own paperwork does the heavy lifting. That paperwork typically comes in layers: the declaration (sometimes called CC&Rs), the bylaws, and the separately adopted rules and regulations. Pet policy usually lives in the rules and regulations, though some declarations address it directly, which matters because rules are easier for a board to change than a recorded declaration.
Well-drafted pet policies cover more than a simple yes-or-no on ownership. According to attorneys who regularly draft these provisions, pet policies should include language pertaining to restrictions on pet types, pet sizes, number of pets, along with rules for pet registration, leash requirements, waste disposal, nuisance behaviors, and liability of owners for damage or injury caused by their pets. Boards are also expected to enforce whatever they adopt consistently. Pet registration allows the board to properly enforce rules and regulations, and residents are required to register their pets — the board can ask to see the animals in person and take photographs for documentation.
Vague wording causes real disputes. Illinois condo and HOA attorneys point to Lakeshore Hills, Inc. v. Adcox, 90 Ill. App. 3d 609 (1980), where a homeowner argued his pet bear qualified as a “household pet.” The court ultimately ruled against the owner as it pertained to his specific pet, but the decision highlights the importance of having well-drafted pet policies in place. An undefined term like “household pet” can leave room for interpretation the board never intended.
Pro Tip: Before closing on any Illinois condo, request the current declaration, bylaws, and rules and regulations directly from the board or managing agent — not an old copy from a real estate portal. Amendments happen, and pet rules are commonly revised.
Number, Breed, and Size Restrictions in Illinois
Illinois sets no ceiling on how many dogs or cats a household can own at the state level. As one detailed review of Illinois pet limits puts it, Illinois sets no cap on the number of common pets like dogs or cats at the state level, but it does prohibit dangerous animals and primates in residential settings statewide. That means the number you can keep in your condo comes down to whatever your association’s rules say, and boards commonly set that number lower than what a city ordinance would otherwise allow.
Breed and size limits follow the same pattern. Declarations frequently exclude certain breeds outright or cap weight at a set number of pounds, and boards are free to prohibit species entirely. An HOA might allow dogs, cats, and fish, but prohibit exotic animals such as ferrets, sugar gliders, and hedgehogs, and breed restrictions are also common, particularly for dogs. Exotic pet bans in particular tend to track state-level restrictions closely — if you’re weighing an unconventional pet, it’s worth reviewing which exotic pets are legal in Illinois before you check whether your building allows them, since a species banned statewide will never be a condo option regardless of what your declaration says. Primates are a clear example: owning a monkey in Illinois already runs into state restrictions long before an association’s rules even come into play.
If your building’s declaration limits you on dogs and cats but stays silent (or more permissive) on smaller companion animals, there’s often more flexibility than owners assume. Condo-friendly alternatives that tend to fit within tighter size and space restrictions include:
- Small mammals and other low-maintenance pets suited to compact living spaces
- Certain rabbit breeds that adapt well indoors
- Chameleons and other contained reptiles, where declarations don’t specifically exclude them
- Insects kept as pets, which rarely trigger the same weight or noise-based restrictions as dogs
Even so, exotic species like a pet scorpion can still fall under a broad “no exotic animals” clause, so confirm with your board before assuming a smaller or quieter animal is automatically exempt from the declaration’s definition of a household pet.
Service Animals and Emotional Support Animals in Illinois
Service animals and emotional support animals are not “pets” under the law, and that distinction changes everything about what a board can restrict. A service animal is trained to perform a specific task tied to a disability, while an ESA works differently. ESAs are not pets — an ESA is any animal that provides support to a person with a disability, and the animal does not need to be trained to perform exact tasks; it can be any animal that provides support, comfort, or aid through companionship, unconditional positive regard, and affection.
Federal and state disability law overrides a no-pets declaration for both categories. The Fair Housing Act, along with the Illinois Human Rights Act, protects tenants from discrimination based on disability, and these laws ensure that service and emotional support animals are accommodated in rental units — the same protection extends to condo owners facing their association. For service animals specifically, the HOA cannot impose pet restrictions on these animals, is not allowed to refuse certain breeds, weights, or sizes, and service animals are also allowed in all areas of the property.
ESA requests work a little differently in practice. Effective January 1, 2020, the Illinois Assistance Animal Integrity Act gave associations a framework for evaluating these requests, but the underlying obligation predates it. Under the longstanding Fair Housing Act, a landlord or condominium association is legally obligated to provide a reasonable accommodation to any resident who has a physical, mental, or emotional disability and needs an emotional support animal, and in the condominium setting this accommodation must be provided even if the association’s declaration contains a no dogs or no pets restriction. Under the Illinois Assistance Animal Integrity Act, a qualifying letter comes from someone with a genuine therapeutic relationship to the requester and does not need to come from a physician specifically.
“Reasonable,” however, does not mean unlimited. An Illinois federal court addressed this directly in a case involving a no-pets high-rise. In Stevens v. Hollywood Towers & Condo. Ass’n, 836 F.Supp.2d 800 (N.D. Ill. 2011), an Illinois federal district court determined that a community association does not necessarily have to grant unlimited, unrestricted access throughout a no-pets building for an emotional support animal, but the terms and conditions of the accommodation offered instead by the association still must be reasonable. A board can negotiate conditions like carrying the animal in common areas; it just cannot deny the accommodation outright.
| Category | Training Required | Can Board Restrict Breed/Size | Legal Basis |
|---|---|---|---|
| Regular pet | No | Yes, under declaration/rules | Association’s own governing documents |
| Service animal | Yes, task-trained | No | ADA, Fair Housing Act |
| Emotional support animal | No | Generally no, but terms can be negotiated | Fair Housing Act, Illinois Human Rights Act, Assistance Animal Integrity Act |
What Happens If You Already Own a Pet When a Ban Is Introduced
Boards do amend pet policies after owners have already moved in with their animals, and how that gets handled usually comes down to a grandfather clause rather than a hard legal mandate. Community association attorneys routinely advise boards to build one in. A well-drafted amendment should include an express exemption for members who already had non-compliant pets prior to the amendment, which helps prevent waiver claims that cite the non-compliance of grandfathered residents.
When a grandfather clause exists, it typically doesn’t transfer with the pet or the unit indefinitely. If an HOA pet policy is new or the board has made amendments, the changes generally will not apply to the pets residents already have, but the association can impose the new restrictions once residents get new pets or once new homeowners join the community. Some Illinois practitioners describe the exemption as tied to the individual owner rather than the unit itself, ending when that specific animal is no longer there. The board can still set guidelines for how grandfather clauses work — for example, the pet exceptions expire if the homeowner no longer has the animal or if there is a change in property ownership.
Important Note: Illinois law does not require a board to grandfather existing pets when adopting a new restriction — it’s a drafting choice, not a statutory mandate. Most association attorneys recommend it anyway, since retroactively forcing out a resident’s existing pet invites disputes and potential litigation over reliance on the prior rule.
Legal guidance for boards frames the grandfather clause the same way: as a fairness tool, not a legal obligation. For existing association residents with pets that do not meet the community’s new rules, boards should consider including a grandfather clause that allows these pets but enforces the rules for any new pets residents may acquire. If your board adopts a new ban and you already own a pet, your first move should be checking whether the amendment includes this kind of exemption language before assuming you’ll need to rehome your animal.
What to Do If You Disagree With Your HOA’s Pet Policy
Start with the governing documents themselves rather than assuming the rule is fixed. Illinois gives unit owners a real voice in how these policies get written. Community members have certain responsibilities to the HOA, like following bylaws and paying dues, but they also have the right to participate in the governance of their HOA, including the right to elect board members, and members can propose changes by a majority vote according to the association’s rules. That process is documented in the Rights and Responsibilities document from the Illinois Department of Financial & Professional Regulation, which is worth reading before you attend a board meeting to raise the issue.
If your disagreement centers on a disability-related need rather than a general preference, you’re dealing with a fair housing matter, not just an internal association dispute. Document your request in writing, include supporting documentation from a provider with a genuine therapeutic relationship to you, and reference the Fair Housing Act and Illinois Human Rights Act protections against disability discrimination directly in your accommodation request. A denial in that context can potentially support a fair housing complaint, which is different from simply disliking a breed or size restriction.
For disputes that don’t resolve through board discussion, condo law attorneys handle exactly this kind of conflict regularly. Firms that represent both owners and associations note that they regularly advise and assist condominium associations and common interest communities in reviewing, revising, and drafting pet policies, and the same attorneys can advise an individual owner on whether a specific rule is enforceable. If you’re moving into an Illinois building from out of state with a pet already in tow, it’s also worth checking Illinois pet import rules so your animal’s paperwork is in order before your association even gets involved.
Ultimately, most pet disputes in Illinois condos come down to documentation on both sides: what the board actually wrote into its rules, and what you can show about your pet, your request, or your legal protections. Reading the declaration closely, registering your pet where required, and raising concerns through the association’s own amendment process resolves far more disputes than most owners expect — and if you’re still house-hunting, it’s worth browsing pet-friendly options and condo-appropriate pet choices before you buy, rather than after.
