Illinois Rent Prices, Caps & Rights: 2025 Renter Guide

If you’re renting in Illinois in 2025, understanding local rent prices, laws about rent increases, and your protections as a tenant is essential. This guide breaks down what renters need to know—from common Illinois rent figures to deposit limits and key legal protections. Let’s get started so you can protect your home and your budget.

What Are Average Rent Prices Across Illinois in 2025?

Average rent prices vary widely by city. According to the Illinois Housing Development Authority:

• Chicago (citywide average): Around $2,200/month for a two-bedroom apartment in 2025.
• Aurora, Rockford, and Peoria: Range from $1,000 to $1,400/month for two-bedroom units.
• Downstate or rural areas: Often $700–$900/month for similar units.

Rents may also fluctuate based on building type, amenities, and landlord policies. For up-to-date statistics and rent maps, see the Illinois Housing Development Authority's data portal.

Rent Control and Rent Caps in Illinois

Illinois does not have statewide rent control. That means—except in subsidized or special housing—landlords can generally set or raise rent to market value so long as they provide proper written notice.

• No rent caps: There’s no legal maximum on how much regular landlords can increase rent at lease renewal or for new tenants^[1].
• Notice required: For month-to-month rentals, landlords must give at least 30 days’ advance written notice before raising rent.
• Chicago exception: Some local ordinances (like Chicago's Residential Landlord and Tenant Ordinance—RLTO) contain extra disclosure requirements, but do not set rent caps. For more, visit the official City of Chicago Renters’ Rights page.

Rent Increase Example in Illinois

If your lease is month-to-month, and your landlord wants to increase rent, they must give you a written notice (30 days in advance). For example: If your landlord delivers notice on September 1, your new rent can't take effect until October 1. If you’re on a fixed-term lease, rent increases are only allowed after your lease term ends or if your lease specifically allows increases within the term.

Security Deposit Limits and Related Fees

Illinois law allows landlords to collect a security deposit but does not set a maximum limit. However, local ordinances—especially in Chicago—have specific rules:

• Statewide: No set cap on deposit amount, but landlords must return the deposit within 45 days of move-out (minus lawful deductions).
• Chicago (per RLTO): Landlords must pay interest on deposits and return them within 45 days. Failure to comply gives renters the right to recover double the deposit plus court costs and attorney’s fees.

Official Forms for Renters: Notices & Complaints

  Official guidance: See notice requirements in Illinois Compiled Statutes—Landlord and Tenant Act.
• Chicago RLTO Security Deposit Interest Rate Summary (Form required in Chicago): Chicago landlords must provide an annual summary of deposit interest rates. The official summary and guidance are available at the City of Chicago Renters’ Services page.

Frequently Asked Questions about Illinois Rent Prices and Caps

1. Can my Illinois landlord raise rent during my lease term?
   No, if you have a fixed-term lease (e.g., one year), your landlord cannot increase rent during that term unless the lease explicitly allows for increases.
2. How much notice must my landlord give before increasing my rent?
   For month-to-month rentals, landlords must provide at least 30 days’ written notice before a rent increase takes effect.
3. Are there any situations where rent increases are capped in Illinois?
   In regular private-market rentals, no statewide caps apply. Subsidized housing or other programs may have their own limits.
4. What should I do if my security deposit isn’t returned?
   First, send a written demand to your landlord. If there’s no resolution, you can file in your local circuit court. Chicago tenants have extra protections under the RLTO.
5. Does Illinois have a statewide agency for landlord-tenant problems?
   No. Issues are handled by county courts, but helpful resources are offered by the Illinois Housing Development Authority and the Illinois Department of Human Rights.
