Security deposit rules in Skokie: how much, where it goes, and getting it back

Since June 2021, security deposits in Skokie are governed by Cook County's Residential Tenant Landlord Ordinance — Skokie has no village ordinance of its own, and Chicago's better-known RLTO stops at the city line. The RTLO caps deposits at one and a half months' rent, gives you the right to pay the excess in installments, and requires the deposit back within 30 days with itemized deductions. Illinois state law adds a receipts-or-refund rule and, in larger buildings, interest. Every rule below links to its source.

The cap is 1.5 months' rent — and you can pay the excess in installments

Under the Cook County RTLO (in force since June 1, 2021), a landlord may not demand a security deposit larger than one and a half times the monthly rent. Anything over one month's rent is payable, at your election, either up front or in up to six equal monthly installments over the first six months of the lease. Skokie never adopted its own tenant ordinance, so the county ordinance is the local law here. Source: Cook County RTLO — official page & ordinance text

Receipt required, and the deposit stays separate from the landlord's money

The RTLO requires a receipt for the deposit and requires landlords to keep tenant deposits separate from their personal accounts. Keep the receipt with your lease — it is the document that proves the amount if the move-out math is ever disputed. Source: Cook County RTLO — official page & ordinance text

30 days to return it, with an itemized list of any deductions

Under the RTLO the deposit must come back within 30 days of move-out, and anything withheld needs an itemized list of deductions — damage repairs beyond normal wear, unpaid rent, and some court costs. The ordinance backs this with penalties when a deposit isn't returned properly. Source: Cook County RTLO — official page & ordinance text

State law adds a receipts-or-refund backstop: full refund at 45 days

Illinois' Security Deposit Return Act runs alongside the county ordinance: to keep any of your deposit for damage, a landlord must send an itemized statement with paid receipts (or repair estimates) within 30 days of your leaving — and if that paperwork never arrives, the Act requires the deposit back in full within 45 days. A court finding of bad faith makes the landlord liable for twice the deposit plus court costs and attorney's fees. Source: Security Deposit Return Act (765 ILCS 710/1)

Interest is owed only in larger buildings — and today it rounds to almost nothing

The RTLO itself does not require interest on deposits. Illinois' Security Deposit Interest Act does, but only in buildings or complexes of 25 or more units and only once the deposit has been held more than six months — at the passbook-savings rate of the state's largest bank, which in recent years has been a small fraction of one percent. Honest translation: in most Skokie buildings, don't expect deposit interest; the protections that matter here are the cap and the return deadlines.

Who's NOT covered: owner-occupied small buildings

The RTLO exempts owner-occupied buildings of six units or fewer, plus a handful of special cases (hotels and motels under 32 days, dormitories, shelters). If your landlord lives in your small building, the county deposit cap and 30-day rule may not apply — the state Return Act's receipts-or-refund rule is then the main protection.

What that means in dollars at today's Skokie rent

The average Skokie rent is $2,179/month as of May 2026 (how we compute this), so for a typical unit:

The most a landlord can demand as a deposit is $3,268 (1.5× the monthly rent).
Of that, only $2,179 (one month) is due up front if you elect installments — the remaining $1,090 can be spread over six monthly payments of about $182.

By ZIP, using each ZIP's current average rent:

ZIP	Average rent	Max deposit (1.5× rent)
60077 (North Skokie / Old Orchard)	$2,230	$3,345
60076 (South Skokie)	$2,053	$3,080

Honest caveat: these are smoothed market averages (Zillow's ZORI index — methodology), not your lease. The legal caps apply to your actual rent, whatever it is — the table just shows the scale at typical Skokie rents.

Moving in or out?

Worth checking alongside the deposit rules: what your ZIP actually rents for (60077, 60076); whether you're signing in the market's soft season, when there's more room to negotiate the whole package; and the rules for rent increases at renewal. If a deposit isn't coming back and the landlord has gone quiet, the free legal-aid resources are exactly for this.
