Pet Rent Laws in Illinois: What Landlords Can Charge and What You Can Negotiate

Pet rent laws in Illinois are looser than most renters expect: no statewide law caps what a landlord can charge for a dog or cat each month. That freedom comes with a catch, because the charge has to be in writing, and assistance animals are exempt from it entirely.

If you’re budgeting for a move, the real question is not just “is it legal?” but “what will I actually pay, and what can I push back on?” This article walks through the rules for deposits, fees, and monthly rent, plus the local and federal protections that change the math for some tenants.

One thing to know up front: the bills discussed below were still proposals in the sources I reviewed, so check the Illinois General Assembly site before signing a lease.

Is Pet Rent Legal in Illinois?

Yes. LeaseRunner’s Illinois guide says housing providers can collect monthly pet rent if the lease states it clearly. Illinois has no dedicated pet rent statute, so general landlord-tenant rules and the lease itself do the work.

Illinois also doesn’t force landlords to allow pets. A “no pets” clause is enforceable for ordinary dogs, cats, and other companion animals, as our breakdown of pet bans in Illinois explains. If a landlord does allow pets, they can attach a price to that permission.

Pet Rent vs. Pet Fee vs. Pet Deposit in Illinois

These three charges get lumped together, but they behave differently. Knowing which one you’re being asked to pay tells you whether you’ll ever see the money again.

Charge	How It Works	Refundable?
Pet Deposit	One-time amount held against damage	Yes, if there is no pet damage
Pet Fee	One-time charge for allowing the pet	No
Pet Rent	Recurring monthly charge added to rent	No

That structure comes from our renter’s guide to pet housing in Illinois. Any refundable pet amount should follow the same return timelines and itemized-deduction rules that apply to security deposits, according to LeaseRunner.

Important Note: Sources disagree on deposit limits. Most describe no statewide cap on pet deposits, while one site (petdepositsbystate.com) reports a 1.5-month total security deposit cap and a ban on non-refundable pet fees. Treat the “no statewide cap” position as the majority view, and ask your landlord to point to the statute if they cite a limit either way.

Does Illinois Cap Pet Rent?

No. TenantPetRights.org lists monthly pet rent as allowed with no state limit. LeaseRunner adds that Illinois doesn’t make landlords pick only one type of pet charge, so a deposit, a fee, and monthly rent can all show up on one lease.

Lawmakers have floated changes. As of 2025, LeaseRunner reported that Senate Bill 1669, which would define pet fees and recurring pet rent and possibly cap them, was still in committee. Hotspot Rentals says House Bill 5183 would let landlords charge either a pet fee or pet rent but not both, with pet rent capped at the lower of 1% of monthly rent or $35.

That same source says HB 3564, which requires full fee disclosure, was already signed and takes effect July 1, 2026. Since I couldn’t confirm the details of these bills from official legislative text, verify their current status before relying on them.

How Much Is Pet Rent in Illinois?

Market rates, not statute, set the price. TenantScreeningBackgroundCheck.com puts typical Illinois pet rent at $25 to $75 per month per pet, with higher-end urban buildings sometimes charging more.

Location matters. Our guide to pets in Illinois apartments cites roughly $25 to $40 a month downstate and higher in Chicago. It also notes that one local Chicago guide puts a one-time pet fee plus monthly rent at $830 or more in year one for a single dog.

Run the annual math before you sign. At $50 a month, pet rent costs $600 a year, which often exceeds the one-time fee a building next door might charge.

Is Pet Rent Charged Per Pet in Illinois?

Usually, yes. Illinois has no rule on whether pet rent is per pet or per household, so each landlord sets the structure. The $25 to $75 range cited above is quoted per pet, and a second animal often triggers a second charge.

Some landlords also limit the number of animals. Steadily notes that Illinois landlords may restrict the type and number of pets allowed. Ask whether the rent is flat, per animal, or tiered before you add a second pet.

Which Pets Can Landlords Charge Pet Rent For in Illinois?

Landlords can generally charge for conventional pets: dogs, cats, and whatever other species the lease approves. Steadily’s Illinois guide says landlords may restrict pets by type and number and may consider weight when judging suitability.

Breed restrictions are also allowed for ordinary pets. If you own a breed that insurers or landlords flag, see our pages on pit bull laws in Illinois and American Bully laws in Illinois. Unusual animals raise a separate question of legality, such as under Illinois hedgehog ownership laws.

Can a Landlord Add Pet Rent Mid-Lease in Illinois?

Generally not without your agreement. Because pet rent must be spelled out in the lease, a landlord can’t normally tack on a new monthly charge partway through a fixed term. Changing the contract mid-term typically requires your signed consent.

Renewal is the exposure point. When your lease ends, a landlord can propose new terms, including pet rent, and you can accept, negotiate, or move. This is general landlord-tenant practice rather than a rule I found stated in a specific Illinois pet statute, so read your lease’s amendment clause closely.

Pet Rent in Rent-Controlled and Local Rules in Illinois

Illinois has no rent control, so pet rent isn’t tied to a regulated rent schedule. The local layer that matters is Chicago. TenantPetRights.org says the Chicago Residential Landlord Tenant Ordinance gives renters some of the strongest protections in the country, and landlords in buildings with 6 or more units must pay interest on security deposits.

The same source says Chicago landlords who break deposit rules can owe twice the deposit plus attorney fees, with a 30-day return deadline (45 if the tenant disputes it). Another source notes that Chicago and Evanston ordinances interact with pet deposits through the overall security deposit framework.

If you rent in a condo or HOA community, building rules can add limits on breed, weight, or species. For a closer look at local limits, see our piece on residential pet limits in Illinois.

Can Landlords Charge Pet Rent for ESAs and Service Animals in Illinois?

No. Assistance animals aren’t pets under housing law. Under the Illinois Assistance Animal Integrity Act, RealESALetter reports that a landlord cannot charge a pet deposit, pet fee, or monthly pet rent for an assistance animal, even in a building that charges other tenants (310 ILCS 120/10).

The statute has been in effect since January 1, 2020, per our Illinois pet housing guide. Landlords also can’t apply breed, size, or weight limits to the animal or require special liability insurance.

Pro Tip: If a landlord adds a pet charge to your ESA or service animal, answer in writing, cite the Fair Housing Act and 310 ILCS 120/10, and keep a copy. Tenants who believe their rights were violated can file a complaint with HUD, as noted by petdepositsbystate.com.

You remain responsible for actual damage the animal causes. A landlord may verify that your documentation is authentic, but can’t demand a specific diagnosis or medical records.

Can Landlords Charge Pet Rent for Visiting or Pet-Sitting Pets in Illinois?

Illinois law doesn’t address guest animals directly, so the lease controls. Many landlords write a clause that requires approval for any animal staying beyond a set number of days, and some attach a fee.

If you’re pet-sitting for a friend, ask first and get approval in writing. A short-term, written okay is far cheaper than defending an unauthorized-pet claim later.

What If You Have an Unauthorized Pet in Illinois?

A landlord can treat an unapproved pet as a lease violation, but can’t take matters into their own hands. According to our guide to pet bans, any eviction must go through the courts under the Forcible Entry and Detainer Act (735 ILCS 5/9-101 et seq.). A landlord can’t change your locks or remove your belongings over a pet.

The practical fix is usually cheaper than a fight. Ask to add the pet to the lease, expect back charges for the months the animal was there, and pay any deposit or fee the landlord would have charged from the start.

1. Read your lease’s pet clause and any notice you received.
2. Contact the landlord in writing before the situation escalates.
3. Offer to sign a pet addendum and pay the standard charges.
4. If you have a disability-related need, submit an accommodation request rather than a pet application.

Is Pet Rent Refundable in Illinois?

No. Pet rent is a recurring charge for the right to keep the animal, so it isn’t returned when you move out. Only a true pet deposit comes back, and only if the unit has no pet damage, as the comparison table above shows.

Deposits follow Illinois security deposit law, which TenantPetRights.org ties to 765 ILCS 710 and 765 ILCS 720. Document the unit’s condition with dated photos at move-in and move-out so deductions stay tied to actual damage.

Can You Negotiate Pet Rent in Illinois?

Yes, and with no statewide cap, negotiation is your main lever. Hotspot Rentals says timing matters most, and that renting during winter can improve your chances of flexibility.

• Offer a higher refundable deposit in exchange for lower monthly rent.
• Provide a pet resume with vaccination records, training certificates, and landlord references.
• Ask for the pet fee to be waived if you sign a longer lease.
• Compare per-pet charges across buildings before you commit.

Whatever you agree to, get it in writing. Our Illinois apartment pet guide stresses that these charges must appear in the lease and should be reasonable.

Is Pet Rent Taxable Income for Landlords in Illinois?

Generally, yes. Pet rent is money a landlord receives from a tenant for use of a rental property, so it is typically reported as rental income on federal and state returns. I didn’t find a source in my research that addresses Illinois treatment specifically, so this reflects general rental-income principles.

Refundable pet deposits are usually treated differently, since the landlord may have to return them. If you’re a landlord, a tax professional can tell you how to book each charge type.

What a Illinois Lease Must Say About Pet Rent

The one firm requirement is clarity. Illinois sources agree that every pet charge needs to be stated in the lease, and the LeaseRunner guide says landlords must list all extra pet charges to avoid disputes. The charge must also be reasonable.

A solid pet clause covers these points:

• The exact monthly pet rent amount and whether it applies per pet
• Any one-time pet fee and any refundable pet deposit, labeled separately
• Which animals, breeds, or weight limits are approved
• The process for adding or removing a pet
• A statement that assistance animals are exempt from pet charges

Illinois also has other animal rules that can affect a rental, such as leash laws and dog bite liability. Moving with an animal from out of state? See our summary of pet import laws in Illinois.
