Can a Chicago Landlord Charge a Pet Deposit?

Yes, a Chicago landlord can charge an additional deposit for a tenant's pet. But how that deposit is characterized, how it's held, and what rules govern its return matter a great deal — because under the RLTO, a deposit is a deposit, regardless of what you call it.

Quick Answer

• Chicago landlords can charge a pet deposit, but if it functions as a security deposit — held to cover potential damages — it's subject to all of the RLTO's security deposit rules.
• That includes interest requirements, separate account requirements, and the return timeline and itemization rules that apply to security deposits generally.

The Naming Problem

Landlords sometimes believe that calling a payment a "pet deposit" rather than a "security deposit" changes the legal category it falls into. In Chicago, it typically doesn't. The question isn't what the payment is called. The question is what it's held for.

If the pet deposit is collected and held to cover potential damage the pet may cause — which is the most common purpose — it functions as a security deposit. That means Chicago's security deposit rules apply to it in full. Interest requirements. Separate account requirements. The 30-day return rule after move-out. The itemization requirements if deductions are taken.

A landlord who collects a pet deposit, calls it something other than a security deposit, and treats it as exempt from RLTO security deposit rules may be in for a surprise when the tenant moves out and knows their rights.

Non-Refundable Pet Fees

There is a distinction worth knowing: a non-refundable pet fee — charged upfront as compensation for the fact that the landlord is accepting a pet at all, not held to cover potential future damage — may be treated differently than a deposit. A true fee, fully disclosed as non-refundable and not held for potential damage, may not trigger the same security deposit obligations.

But this distinction requires that the fee be genuinely non-refundable, clearly disclosed as such in the lease, and not structured in a way that looks like a deposit with a different label. A "non-refundable pet deposit" is a contradiction in terms — deposits are refundable instruments by definition. That kind of language creates confusion and may invite a tenant claim that the rules around deposits apply regardless of the "non-refundable" label.

"Call it a pet deposit or a pet fee — Chicago's rules care about what you're holding and why, not what you named it."

Pet Deposits and Accommodation Requests

This connects directly to the fair housing layer of the pet question. If a tenant has an emotional support animal or a service animal and submits a legitimate accommodation request, the landlord generally cannot charge a pet deposit for that animal — the accommodation request changes the legal status of the animal in the unit.

Charging a pet deposit for an animal that qualifies under a housing accommodation isn't just a lease issue. It can be a fair housing violation with its own set of consequences.

The full security deposit framework that governs how any deposit must be held and returned is covered in the Chicago Security Deposit Laws overview. The Chicago Lease Laws overview covers the broader lease context. Dweller IQ can help you think through the structure of a pet deposit before you put it in the lease.
