Rule verified: 2026-10-28
Quick answer
Yes — Chicago landlords must pay interest on qualifying security deposits. Chicago's RLTO requires annual interest on security deposits in 25+ unit buildings — the City Comptroller publishes the rate each year, and it has been 0.01% in recent years (2026 = 0.01%).
State statute (official text) · 2026-10-28The current rate in Chicago
Chicago's rate is 0.01% for the period 2026 (published annually by the City Comptroller). The rate is computed and published by the City Comptroller every year — it is not a fixed statutory percentage. The published rate has been 0.01% in recent years; the 2026 value of 0.01% is per a secondary source, so confirm against the City's current-year notice.
When the rate changes
The Chicago rate is not written permanently into law — the publishing authority re-announces it periodically, and the number can move up or down with it. When a new value publishes, this page's rate, the worked example below and the verified date all move together. Before relying on a figure from any source — including this one — check the official announcement linked below for the current period.
Who the rule applies to
Rental units covered by the Residential Landlord and Tenant Ordinance (RLTO): buildings with 25 or more units. Interest accrues on deposits held more than 6 months. Cook County's RTLO carries its own separately published rate for suburban coverage.
Rules that go further
- Interest is owed only on deposits held more than six months.
- Cook County's RTLO has its own separately published rate — suburban Cook tenants should check the county figure, not the Chicago one.
Chicago vs Illinois state law
Illinois law already requires interest statewide, and Chicago layers its own city rate and rules on top — where both apply, the tenant gets the more protective treatment. Full statewide picture: Illinois security deposit interest.
What that looks like in dollars
For a $2,000 deposit held for a full year at the current 0.01% rate, the interest owed works out to $0.20:
| Deposit | Rate | One year's interest |
|---|---|---|
| $2,000 | 0.01% | $0.20 |
| $3,500 | 0.01% | $0.35 |
Partial years are prorated. This example applies the published rate mechanically — the statute and the calculation method section above control in a real dispute.
