Where to rent a car in Chicago and what to expect

You can rent a car at Chicago's two major airports, downtown near Michigan Avenue, and in neighborhoods across the city. O'Hare International Airport (ORD) has rental counters for every major company in the baggage claim area — Hertz, Enterprise, Avis, Budget, National, and others. Midway International Airport (MDW) on the southwest side has a smaller selection but the same major chains. If you're flying in and want to skip the airport lines, you can reserve online and pick up at a downtown location on North Michigan Avenue or at a neighborhood branch instead.

Downtown Chicago has rental locations within walking distance of hotels and the Loop. Enterprise, Hertz, and Avis all operate multiple branches in the central business district. Neighborhood locations in Lincoln Park, Wicker Park, and near the Museum Campus give you options if you're staying elsewhere or want to avoid airport crowds and pricing. Prices and vehicle availability vary by location and date, so comparing across pickup points before you book can save money — a downtown pickup might be cheaper than the airport, or vice versa depending on demand.

Key Takeaways

  • O'Hare and Midway both have rental counters for major companies, but O'Hare has more options and longer hours.
  • Downtown and neighborhood locations often have lower daily rates than airport pickups, though you pay for convenience if you need a car when ready after landing.
  • You need a valid driver's license, a credit card in your name, and proof of insurance or the option to purchase the rental company's coverage.
  • Chicago's parking fees and congestion pricing on I-90 add to your rental cost if you're driving downtown or to the airport.
  • One-way rentals between Chicago locations are usually free, but returning to a different city costs extra.

Documents and requirements you'll need at pickup

Bring your valid driver's license — a U.S. state license, passport card, or international driving permit all work. You must be at least 21 years old to rent; drivers under 25 typically pay a daily surcharge of $15 to $30. Have a credit card in your own name ready — the rental company will place a hold on it for the estimated rental cost plus a deposit, usually $200 to $500 depending on the vehicle class. Debit cards are rarely accepted, and some companies won't hold a debit card even if they say they will.

Proof of insurance is the third requirement. If you have a personal auto policy, bring your insurance card or a declaration page showing your name and coverage limits. If you don't have insurance or your policy doesn't cover rentals, you'll purchase the rental company's collision damage waiver (CDW) and liability coverage at the counter — this typically runs $15 to $25 per day. Some credit cards offer rental car coverage if you charge the full rental to that card; call your card issuer before you book to confirm what's covered and whether you need to decline the company's insurance.

Airport pickup versus downtown and neighborhood locations

O'Hare and Midway charge a 6% airport facility fee on top of the daily rate, plus Illinois's 6.25% sales tax and Cook County's 1.5% car rental tax — that's a 13.75% markup on the base price. A $50-per-day car becomes $56.88 at the airport. Downtown and neighborhood locations charge only the state and county taxes, no facility fee. The trade-off is time: if you land at 6 p.m. and need a car when ready, the airport counter is faster than driving downtown. If you're staying overnight or arriving early in the day, a downtown pickup saves money and avoids the airport crowd.

Midway is closer to downtown (about 20 minutes by car) than O'Hare (about 30 minutes), so returning a car to Midway costs less in time and parking if you're staying in the Loop or near the lakefront. Both airports have rental car shuttles that run every 5 to 10 minutes during the day. If you're renting for multiple days and plan to stay downtown, picking up at a Michigan Avenue location and returning there avoids the airport fee entirely and lets you keep the car parked at your hotel or a paid lot rather than at the airport.

Daily rates, insurance, and hidden costs in Chicago

Economy and compact cars rent for $30 to $60 per day at neighborhood locations and $40 to $75 at the airport, depending on the season and how far ahead you book. Midsize sedans run $50 to $90 per day. These are base rates before taxes and fees. The 13.75% airport markup, plus the optional insurance if you don't have coverage, can add $10 to $25 per day. If you decline the rental company's CDW and damage occurs, you're liable for the full repair cost — sometimes thousands of dollars — so the insurance decision matters.

Chicago-specific costs add up if you're driving downtown or to the airport. Parking in a downtown lot costs $15 to $40 per day depending on location and whether you book in advance. The Chicago Congestion Pricing Program charges $5 to $6 per trip on I-90 between the Loop and O'Hare during peak hours (6 a.m. to 10 a.m. and 3 p.m. to 7 p.m., Monday through Friday). If you drive to or from the airport during rush hour, budget for multiple tolls. Parking at O'Hare or Midway for a multi-day rental costs $8 to $15 per day if you leave the car there, though most renters return it before leaving the airport.

Booking online versus at the counter

Booking online before you arrive locks in a rate and guarantees a vehicle type (or at least a category). Prices fluctuate daily, and booking a week or two ahead is usually cheaper than booking the day before. Major rental sites like Hertz.com, Enterprise.com, and Avis.com show rates for each location; comparison sites like Kayak and Autoslash.com pull rates from multiple companies at once. Read the cancellation policy — most online bookings allow free cancellation up to 24 hours before pickup, but some discounted rates don't.

Booking at the counter after you land gives you flexibility if your plans change, but you'll pay more and may not get your preferred vehicle type if the lot is low on inventory. Counter staff can sometimes offer upgrades or discounts not shown online, but this is rare and not may provide. If you book online and the counter offers a lower rate, ask if they'll match it — some companies will, some won't. For a one-way rental (picking up in Chicago and returning elsewhere), book online to lock in the drop-off location and any one-way fees, which can be substantial.

One-way rentals and returning to a different city

Renting a car in Chicago and returning it to another city costs extra. A one-way rental from Chicago to Milwaukee or Indianapolis typically adds $30 to $80 to the total cost, depending on distance and the company. Returning to a city more than 200 miles away — like St. Louis or Detroit — can add $100 to $200. These fees vary by company and by which direction you're traveling; returning south is sometimes cheaper than returning north, for example.

If you're planning a one-way trip, book it as a one-way rental from the start rather than booking a round-trip and canceling the return. One-way bookings show you the drop-off fee upfront. Some companies waive one-way fees for rentals within Illinois or to nearby states if you book far enough in advance, so check each company's current policy. For trips longer than a few days, a one-way rental is often cheaper than paying for parking at your destination and driving back to Chicago to return the car.

Frequently Asked Questions

Can I rent a car with an out-of-state or international driver's license?

Yes. A valid U.S. state license, passport card, or International Driving Permit all work. If your license is in a non-Latin alphabet (Chinese, Arabic, Cyrillic), bring an International Driving Permit along with it. Some companies ask for a second form of ID, so bring a passport or state ID as backup.

What happens if I return the car late?

Late fees vary by company but typically run $25 to $50 for the first hour, then $10 to $25 per hour after that. Some companies charge a flat daily rate if you're more than a few hours late. Call the rental location as soon as you know you'll be late — they may waive or reduce the fee if you notify them in advance. Check your contract for the exact policy before you pick up the car.

Do I need to fill the gas tank before returning the car?

Yes. Most rental agreements require you to return the car with a full tank. If you don't, the company charges you for fuel at a premium rate — usually $5 to $8 per gallon, much higher than gas station prices. Fill up at a station near the rental location before you return the car. Some companies offer a pre-purchase fuel option at booking, which locks in a lower per-gallon rate if you know you won't return with a full tank.

Can I rent a car if I'm under 25?

Yes, but you'll pay an underage driver fee of $15 to $30 per day on top of the base rate. You must be at least 21 and have a valid license. Some companies have higher age minimums for certain vehicle types — luxury or large SUVs may require drivers to be 25 or older. Check the company's age policy when you book.

What's the difference between a collision damage waiver and liability insurance?

A collision damage waiver (CDW) covers damage to the rental car itself if you're in an accident. Liability insurance covers damage you cause to other vehicles or property. Most rental companies require you to have liability coverage — either through your personal policy or theirs. CDW is optional but recommended if your personal insurance doesn't cover rentals. Ask your insurance company what's covered before you decline the rental company's coverage.
