If you own a rental home in the Naperville area and you're still on the fence about pets, you're not alone. We talk to owners every week who have either lost a good tenant over a no-pet rule or, on the flip side, ended up with $1,200 in carpet damage because they never put anything in writing. Both situations are avoidable. This post covers what a solid pet policy actually looks like, why the details matter more than most owners realize, and how getting this one document right can protect your property and your cash flow.

A No-Pet Policy Isn't the Safe Play You Think It Is
A lot of owners assume refusing pets keeps their property safer. We get it. But here's what we actually see in the market.
One owner we work with set a strict no-pet policy on a single-family rental in Downers Grove. The property sat vacant for over three weeks. During that same stretch, comparable pet-friendly listings nearby were renting in under 10 days. Once they adjusted the policy to allow one dog under 40 lbs with a $350 refundable deposit, they were under lease within days.
About 43% of renters in the U.S. own a pet, according to recent survey data. In suburban Chicagoland, where single-family homes dominate and backyards are common, that number skews heavily toward dog owners. A blanket no-pet policy can eliminate roughly 37–39% of your potential renter applicant pool, since studies show that approximately that share of renters own pets., and in a market where Yellow Key's average time on market is 8 days, extended vacancy is a cost you feel immediately. You can see exactly what that extended vacancy costs you using our Vacancy Loss Calculator.
The screening process is what protects your property. Not the pet restriction.
What a Pet Policy Actually Needs to Say
A pet policy that just says "no pets" or "pets allowed" is not a pet policy. It's a conversation waiting to go wrong.
A well-written policy should cover:
- Species and breed: Which animals are permitted? Are there breed restrictions? HOA communities in DuPage County often restrict certain dog breeds, so your policy needs to match those governing documents.
- Size limits: Many owners cap weight at 25 to 50 lbs. Be specific. "Medium-sized dogs" is not enforceable.
- Number of pets: One pet? Two? Set a hard limit.
- Deposit amount: In DuPage County, $250 to $500 per pet is standard. Yellow Key charges refundable deposits, not non-refundable fees, and that distinction matters under Illinois law.
- Tenant responsibilities: Waste removal, flea treatment at move-out, lawn repair if applicable. Write it out.
- Unauthorized pet clause: What happens if a tenant brings in an undisclosed pet? Your policy should address this directly.
Vague language in a pet policy is how you end up with a dispute you cannot win.
Use a Separate Pet Addendum, Not the Lease Body
This is one of the most common mistakes we see from owners who self-manage or who worked with less organized teams before coming to Yellow Key.
When pet terms are buried inside the main lease, updating them at renewal becomes messy. You either redraft the whole document or end up with conflicting language across renewal cycles. Yellow Key charges a $200 lease renewal fee, and part of what that covers is keeping your lease documents current and clean. A standalone pet addendum makes that process straightforward.
The addendum should reference the main lease, stand alone as a signed exhibit, and be specific enough to function as a standalone legal document if it ever needs to.
Refundable Deposits vs. Pet Rent: Which One Actually Protects You?
A lot of owners have shifted toward monthly pet rent, typically somewhere in the $25 to $75 per month range, because it looks like extra income. And it is income. But it cannot be applied to damage at move-out.
In Illinois, pet rent is generally understood as a recurring fee rather than a security deposit, meaning it typically cannot be applied to cover move-out damage the way a security deposit can. Landlords concerned about pet-related damage may be better served by collecting a proper pet security deposit—subject to all applicable security deposit rules—rather than relying on pet rent alone, since pet rent is not structured or legally treated as a damage reserve. Consult a local attorney for guidance specific to your situation.
A refundable pet deposit, on the other hand, is specifically set aside for damage. Yellow Key charges refundable deposits because they hold up when it matters. When Juan, our maintenance coordinator, walks through a unit at move-out and identifies pet-related damage, a documented, refundable deposit gives the owner a real path to recovery.
Illinois requires security deposits to be returned within 45 days of lease termination under the Illinois Security Deposit Return Act; if no itemized statement of deductions is provided within 30 days of the tenant vacating, the landlord must return the full deposit within that same 45-day period. Illinois has no statewide ordinance capping pet deposit amounts, giving landlords in many areas — including much of DuPage County — significant flexibility to set amounts that reflect the actual risk, though owners should verify whether their specific municipality has adopted local rules. Just make sure any deposit you charge is handled in compliance with state law.

Document the Property's Condition Before a Pet-Owning Tenant Moves In
No deposit protects you if you cannot prove the damage was new.
We worked with an owner who came to us after self-managing a townhome in suburban DuPage County. A tenant had kept an undisclosed cat, and because there was no written pet policy and no move-in inspection on file, the owner had zero documented financial recourse when the unit needed $1,200 in carpet and odor remediation at move-out. The damage was real. The paper trail was not.
At Yellow Key, we use Rentvine to document move-in conditions with timestamped photo reports. Every room, every floor, every surface. When a pet-owning tenant moves out, the comparison is documented and defensible. Without that baseline, even a perfectly written pet addendum loses most of its teeth. Our Rent-Ready Guidelines outline exactly what condition we expect a property to be in before a tenant moves in, which also establishes a clear baseline for any move-out comparison.
Fair Housing, ESAs, and Why This Trips Up Self-Managing Owners
Here's one most owners don't see coming.
Federal fair housing law and Illinois state law both require landlords to make reasonable accommodations for tenants with documented emotional support animals. That applies regardless of what your pet policy says. You cannot charge a pet deposit for an ESA. You cannot deny housing based on the presence of one.
Anthony, who leads our owner relations and leasing process, has worked with multi-family property owners who tried to enforce a blanket no-pet rule across all units. Once it came out that one tenant had an ESA with proper documentation, the owner had no written procedure in place for handling accommodation requests. That gap created fair housing exposure they hadn't planned for.
Your pet policy needs a section that acknowledges ESA and service animal accommodations, explains the documentation process you'll follow, and confirms that your no-pet or limited-pet rules do not apply in those situations. It's not optional language. It's required.
HOA Properties Need an Extra Layer
If you own a townhome or condo unit in a DuPage County community managed by an HOA, your pet policy has to line up with the association's governing documents, not just your own preferences.
HOAs in this area frequently restrict:
- Total number of pets per unit
- Specific dog breeds (pit bulls and rottweilers are common examples)
- Pet weight limits
- Common-area pet rules
If your lease allows two dogs and the HOA allows one, your tenant is going to get caught in the middle. And any fines the HOA issues for violations can pass through to you as the unit owner. We've seen that happen. It's an expensive oversight for something that takes about 15 minutes to verify up front.
Before writing your pet policy, pull your HOA documents and review the pet section. Then write your policy to be equal to or more restrictive than what the HOA permits.
What to Do at Renewal
A good pet policy doesn't end at lease signing. It needs to carry forward cleanly at renewal.
If a tenant brought a pet mid-lease and you approved it with an addendum, that addendum should be re-signed or explicitly incorporated into the renewal agreement. If pet deposit amounts or conditions have changed, update the addendum at renewal rather than assuming the original terms still apply.
Yellow Key's $200 lease renewal fee includes a review of the existing lease and addenda, so nothing gets carried forward on autopilot without a fresh look. One client described the process simply: Anthony listens, communicates fast, and always has the owner's best interests in mind while keeping tenants satisfied too. That balance is easier to maintain when the paperwork is in order going into every renewal. You can read more experiences like that on our Testimonials page.
FAQ
Does Illinois law cap how much I can charge for a pet deposit?
Illinois does not set a statewide cap on residential security or pet deposits for most landlords. DuPage and suburban Will County owners have flexibility to set deposit amounts. That said, the deposit must be handled in compliance with state law, including the 45-day return window after lease termination, or 30 days if the landlord is itemizing deductions.
Can I charge a pet deposit for an emotional support animal in Illinois?
No. Federal fair housing law and Illinois law both prohibit charging a pet deposit for a documented emotional support animal or service animal. Your pet policy should address ESA accommodations in writing so you have a clear process when a request comes in.
What happens if a tenant brings in an unauthorized pet?
Your lease or pet addendum should spell this out explicitly. Common approaches include a written warning, a required retroactive pet deposit, or grounds for lease termination if the tenant refuses to comply. Without that language in writing, your options are limited. If a situation escalates to the point of needing to remove a tenant, see our step-by-step breakdown of the eviction process for landlords in IL.
Should I charge pet rent or a refundable pet deposit?
In Illinois, security deposits—including any pet deposit—are subject to strict rules about how they can be applied at move-out; landlords should review state law carefully before applying any collected fees toward damage claims. A refundable pet deposit can. If protecting the condition of your property is the goal, a refundable deposit gives you actual financial recourse when documented damage is present at move-out.
Does my pet policy apply to HOA-managed properties in DuPage County?
Your policy has to work within the HOA's governing documents. If the HOA restricts breeds or limits the number of pets, your lease must be at least as restrictive. Writing a policy that conflicts with HOA rules creates liability for you as the unit owner if your tenant violates association rules.
If I allow pets, what's a reasonable deposit amount for this market?
In the DuPage County rental market, $250 to $500 per pet is the typical range. The right number depends on the property type, flooring material, and the size or breed of the animal. Refundable deposits in that range are defensible and standard enough that they rarely push away an otherwise qualified applicant.
If writing a pet policy feels like it's generating more questions than answers, that's a pretty normal place to land. We're happy to talk through how we handle it for the properties we manage across Naperville and the surrounding suburbs.
