Illinois is one of the many distinct rental markets across the United States, with its own mix of prices, laws, and local customs. Whether you are moving to Chicago, moving to Aurora, moving to Naperville, or simply comparing Illinois against other parts of the country, understanding what you will actually pay — and the legal protections you are entitled to — can save you thousands of dollars a year. This guide breaks down current average rents by bedroom size and metro area, explains the security deposit rules, walks through Illinois's tenant protections, and shows you exactly how much income you need to rent comfortably here.
Every dollar figure below is grounded in public rental data and current state statute. Because rents move month to month and local ordinances can be stricter than state law, treat these as well-sourced planning benchmarks rather than a quote for any specific apartment. Use the free calculators linked throughout to run your own numbers.
Like every state, Illinois blends high-cost urban cores with far more affordable smaller communities, and the right budget depends entirely on where — and how — you choose to live.
Average Rent in Illinois (2026)
As of mid-2026, the average asking rent for a one-bedroom apartment in Illinois is approximately $1,400 per month, according to Zillow rental market data and U.S. Census American Community Survey figures. That is roughly in line with — or below — the national average of about $1,523. Rents across the state have been relatively steady over the past year.
| Bedroom Type | Typical Statewide Rent | Notes |
|---|---|---|
| Studio | ~$1,090 | Cheapest option; common near universities and downtown cores |
| 1 Bedroom | ~$1,400 | Statewide Zillow average, mid-2026 |
| 2 Bedroom | ~$1,710 | Most popular for couples and roommates |
| 3 Bedroom | ~$2,130 | Families; larger gap between metro and rural areas |
Ranges reflect Zillow Rentals and U.S. Census American Community Survey data as of 2026. Actual asking rents vary by neighborhood, building age, and season.
Rent by Major Illinois Metro
Illinois is really several different rental markets stacked into one state. The largest metros tend to run higher than rural and smaller-town areas. Here is roughly what a one-bedroom costs across the biggest metros:
| Metro Area | Approx. 1-BR Rent | vs. State Average |
|---|---|---|
| Chicago | ~$1,700 | Dominates, above average |
| Aurora | ~$1,350 | Suburban |
| Naperville | ~$1,650 | Above average |
| Springfield | ~$1,000 | Below average |
If your job or school allows flexibility, living outside the priciest metro can cut your housing cost substantially. To compare Illinois against other states side by side, use our Cross-State Rent Comparison tool, or drill into individual cities in our City Guides.
Renting in Illinois: What Drives the Cost
Several forces shape what you pay in Illinois, and understanding them helps you negotiate and choose where to live. The largest is geography: employment centers such as Chicago, Aurora, and Naperville command premiums because of concentrated jobs, universities, and amenities, while smaller cities and rural towns cost a fraction of those figures. If your commute allows flexibility, living even 30–45 minutes outside the priciest metro can cut your housing bill by 15–35%.
The numbers are concrete in Illinois. The priciest metro, Chicago, averages about $1,700 for a one-bedroom, while Springfield sits near $1,000 — a spread of roughly $700 a month. That gap is often larger than the difference between a studio and a two-bedroom in the same city, so where you live usually matters more than the size of the unit you pick.
Timing matters. Across most of Illinois, leases signed in late spring and summer (roughly May through August) cost more because demand peaks with graduation and the moving season. In high-demand metros like Chicago the seasonal swing can be steeper, while slower markets such as Springfield move less — so the savings from timing your search depend on which metro you target.
Building type and age move the number too. Older garden-style apartments and walk-ups generally rent below brand-new mid-rise and luxury buildings with amenities like gyms and rooftop decks. A studio or one-bedroom is far cheaper than a two- or three-bedroom, which is exactly why so many renters in Illinois split a larger unit with a roommate to lower their effective rent per person.
Total cost is more than the rent line. Utilities, parking, pet fees, and renters insurance add up, and their size varies by region — cooling-dominated in hotter parts of Illinois, heating-dominated in colder ones. Capture every line item with our Hidden Monthly Cost Calculator before you sign, so there are no surprises in month one.
Security Deposit Rules in Illinois
Illinois has no single statewide statutory cap on security deposits. Landlords most often request one month's rent, but the exact amount is set by your lease. Because local city ordinances can be stricter, confirm the current limit — and any city-specific rule — with the Illinois Attorney General's office or your local housing authority before you sign.
Rent Control & Tenant Protections in Illinois
Illinois has no statewide rent-control law. Chicago's Residential Landlord and Tenant Ordinance (RLTO) sets deposit-return and notice rules but does not cap rents.
Notice Periods & Tenant Rights in Illinois
Illinois gives renters a baseline set of protections. A few rules are worth memorizing before you sign a lease:
- Rent-increase notice: In Illinois, a landlord must generally give at least 30 days' written notice before raising rent on a month-to-month tenancy (longer notice may apply to larger increases — check state statute).
- Ending a tenancy: For month-to-month renters, landlords typically must provide 30 days' written notice; tenants usually give the same. Fixed-term leases follow their own terms.
- Habitability: Landlords must keep the unit livable — working plumbing, heating, weatherproofing, and safe conditions. You have legal remedies if repairs are ignored.
- Document the condition: Walk through the unit in writing and with dated photos before you move in to protect your deposit. Our Rental Inspection Checklist makes this easy.
When you find a place, walk through it carefully and document the condition in writing and with photos before you move in — that record protects your deposit when you leave.
Estimated Monthly Utilities in Illinois
Rent is only part of your housing budget. For a typical apartment (about 900 sq ft / 85 m²), plan for these monthly utility costs in Illinois:
| Utility | Typical Monthly Cost |
|---|---|
| Electricity, gas, water, garbage | ~$200 |
| Home internet (100 Mbps+) | ~$65 |
| Renters insurance | $15 – $25 |

Cost of Living & Taxes in Illinois
Illinois has a progressive state income tax, so your take-home pay after taxes is smaller than in no-income-tax states. When you run the affordability math below, budget for state tax — it raises the gross income you need to rent comfortably.
Beyond rent, everyday costs in Illinois — groceries, transport, and insurance — sit near the national norm, but the single biggest budget lever is which metro you choose. The gap between the most expensive metro (Chicago at ~$1,700) and the most affordable (Springfield at ~$1,000) is about $700 a month for a one-bedroom — roughly 70% of the cheaper metro's rent.
Illinois Metro Rent Deep-Dive
Chicago runs about $1,700 for a one-bedroom — dominates, above average. That is about $300 above the Illinois statewide average of $1,400, so Chicago stretches a typical renter's monthly budget.
Aurora runs about $1,350 for a one-bedroom — suburban. That is about $50 below the Illinois statewide average of $1,400, so Aurora eases a typical renter's monthly budget.
Naperville runs about $1,650 for a one-bedroom — above average. That is about $250 above the Illinois statewide average of $1,400, so Naperville stretches a typical renter's monthly budget.
Springfield runs about $1,000 for a one-bedroom — below average. That is about $400 below the Illinois statewide average of $1,400, so Springfield eases a typical renter's monthly budget.
Total Estimated Monthly Cost in Illinois
Adding rent, utilities, and internet together gives a more realistic monthly figure:
1-BR: Rent $1,400 + Utilities $200 + Internet $65 = $1,665
2-BR: Rent $1,710 + Utilities $230 + Internet $65 = $2,005
Splitting a two-bedroom with a roommate can dramatically lower your per-person cost — often to less than a solo studio. Our Roommate Rent Splitter divides rent fairly even when bedrooms are different sizes.
How Much Income Do You Need to Rent in Illinois?
The most widely used guideline is the 30% rule: spend no more than 30% of your gross (pre-tax) monthly income on rent. To afford the median one-bedroom rent of $1,400, you would need about $4,670 per month, or roughly $56,040 per year before taxes. Many renters — especially in the priciest metros — spend well above 30% and are considered "cost-burdened."
Note that the 30% figure is pre-tax. After federal and Illinois income taxes, your take-home pay is smaller, so the rent you can truly afford may be below the gross math — our calculator factors taxes in. If the median rent pushes you above 30%, common ways to close the gap are taking a roommate, choosing a smaller unit, or living in a less central neighborhood.

Renting is not "throwing money away" — it buys flexibility, predictable maintenance, and freedom from market risk, which is valuable if you may relocate for work or are still building savings. Buying makes more sense once you plan to stay put for several years and can clear the down payment, closing costs, and ongoing ownership expenses. The breakeven point depends on Illinois home prices, mortgage rates, and how fast local rents rise.
A simple way to decide: compare your all-in monthly rent against the estimated monthly cost of owning a similar home (mortgage, taxes, insurance, maintenance) using our Rent vs Buy Break-Even Calculator. If owning costs materially more per month and you might move soon, renting keeps your options open. If the gap is small or negative over your time horizon, buying may build equity faster.
Money-Saving Tips for Illinois Renters
- Compare metros. Living 30–45 minutes from Chicago can cut rent by 15–30% — in Illinois that keeps roughly $180 a month in your pocket.
- Target Springfield if you can. It is the most affordable major metro in Illinois at about $1,000 for a one-bedroom, often hundreds less than Chicago.
- Time your search. Rents tend to soften in late fall and winter (October–January) when demand drops across Illinois.
- Negotiate concessions. In softer markets, landlords offer one to two months free — always ask about the net effective rent, not just the advertised rate.
- Know your deposit rights. Understand the deposit rules above and do not overpay; document the unit's condition at move-in with our Rental Inspection Checklist.
- Budget for the full move-in. First month, deposit, and moving costs add up fast — estimate them with the Move-In Cost Calculator.
