How Much Can I Charge for a Security Deposit in Chicago?

Quick Answer

• Chicago does not set a maximum security deposit amount — landlords can charge what the market will bear.
• But the RLTO's obligations kick in the moment you collect it, regardless of how much it is.
• Before deciding on an amount, it's worth understanding what obligations come with it — Dweller IQ can walk you through exactly what the RLTO requires.

No Cap, But Don't Get Too Comfortable

Unlike some cities and states, Chicago doesn't limit how much a landlord can collect as a security deposit. If you want to ask for three months' rent, there's no ordinance that says you can't.

But that freedom comes with a catch. The higher the deposit, the bigger the potential penalty if you mishandle it. The RLTO's consequences for noncompliance are tied to the deposit amount — which means more money collected is more exposure if you miss a step.

What Counts as a Security Deposit

This is where landlords sometimes get tripped up. The RLTO's definition of "security deposit" is broader than most people assume. Money collected to cover potential damages, unpaid rent, or any future obligation — whatever you call it on the lease — may be treated as a security deposit under the ordinance.

Trying to relabel a deposit as something else to escape the rules is a move that has not gone well for Chicago landlords in court.

The Amount Sets the Stakes

Here's what's important to understand before you decide what to collect: the security deposit rules don't change based on amount. The same obligations apply whether you take $500 or $5,000. But the penalties for getting it wrong scale with the amount.

That's a math problem worth thinking about before you ask for more than you need. The full framework for what those obligations look like is covered in the Chicago Security Deposit Laws guide for landlords.
