How Old Do You Have to Be to Rent a Car in Chicago? Complete Guide

If you’re a young traveler planning a Chicago trip, the age question comes up before almost anything else: can you even rent a car, and how much extra will it cost? The short answer is that 21 is the practical minimum at most companies, but the real picture — surcharges, which brands are friendliest to under-25 drivers, and whether you need a car at all — is more nuanced than a single number.

What Is the Minimum Age to Rent a Car in Chicago?

Most major rental companies in Chicago set 21 as the baseline minimum age. Drivers aged 21–24 fall into a middle tier: they can rent, but they pay a young driver surcharge on top of the base rate, typically $25–$45 per day. Once you turn 25, you rent at the standard rate with no extra fee. A handful of companies — Enterprise, National, and Alamo among them — will rent to drivers as young as 18 at some locations, though this is location-specific rather than a blanket brand policy, and the fees for under-21 drivers are noticeably steeper. If you’re under 21 and hoping to rent, call the exact pickup location in advance rather than assuming the brand’s general policy applies everywhere.

How Much Is the Young Driver Surcharge in Chicago?

Budget for $25 to $45 per day extra if you’re between 21 and 24. Enterprise tends to sit at the lower end, averaging $25–$30/day, while Hertz and Avis run higher, often $35–$45/day. Over a full week that gap adds up fast — an extra $175 to $315 depending on which company you book with. The good news is this surcharge is one of the more controllable costs in the whole trip: booking early and comparing multiple companies side by side (rather than defaulting to whichever counter is closest at the airport) can meaningfully cut what you pay. On our comparator, filtering results by total price rather than base rate is the fastest way to see which company actually comes out cheapest once the surcharge is included.

Best Car Rental Companies in Chicago for Young Drivers

If you’re under 25, not all companies are equal. Enterprise and its sister brands, National and Alamo, generally offer the most competitive under-25 rates and the widest age flexibility, including some locations that will rent to 18-year-olds. Budget and Payless also tend to charge lower young driver surcharges than Hertz or Avis at Chicago pickup points. One consistent pattern worth knowing: off-airport locations, reachable by a short shuttle ride, often charge noticeably lower surcharges than the counters directly inside the airport terminals — worth the extra ten minutes if you’re trying to save money.

Renting a Car at Chicago O’Hare (ORD) vs. Midway (MDW)

O’Hare and Midway both have full rental counters, but the pickup experience differs. At O’Hare, every major company operates out of the Consolidated Car Rental Facility (CCRF) next to the airport — you get there via the free Airport Transit System (ATS), an automated rail that runs 24/7 and takes about five minutes from any terminal. Midway’s rental setup is more compact and typically has a shorter walk from baggage claim. In terms of rates, neither airport is consistently cheaper across the board — it varies by company and week — so it’s worth checking both if your itinerary allows flexibility on which airport you fly into.

Do I Need a Rental Car in Chicago as a Tourist?

Not necessarily. Chicago’s public transit, run by the CTA, is genuinely good by U.S. standards, and the El train plus bus network covers the areas most visitors care about: downtown (The Loop), the Magnificent Mile, Wicker Park, Wrigleyville, Lincoln Park, and Hyde Park. If your trip is mostly city sightseeing, museums, and neighborhood exploring, you can skip the rental altogether and save the young driver surcharge entirely. Where a car becomes genuinely useful is day trips outside the city — Milwaukee, Galena, the Indiana Dunes, or the wider Illinois countryside are all easiest, and often only really practical, with your own wheels.

Tips for Young Drivers Renting a Car in Chicago

Book early. Rates climb and the cheapest inventory (usually the companies with the lowest young driver surcharges) sells out first, especially for summer weekends. Understand your insurance options before you get to the counter — a young driver surcharge is unavoidable, but paying for insurance you don’t need is not, so check what your credit card or travel insurance already covers. And once you’re behind the wheel, know that Chicago’s downtown grid is logical once you learn The Loop, but the expressways (I-90, I-94, I-290) see aggressive lane changes, and street cleaning rules mean parked cars get towed more often than out-of-towners expect. Stick to paid garages near the Magnificent Mile, Millennium Park, and the Museum Campus, and keep Waze or Google Maps running.

Whichever company you end up with, the booking basics are the same everywhere on our platform: the rate you see is the rate you pay, cancellation is free up to 48 hours before pickup, and you don’t pay anything today — just at pickup.

Final Tips for Young Drivers Renting in Chicago

If you’re 25 or older, none of this applies — book normally at standard rates. If you’re 21–24, budget for the surcharge but shop around, since the gap between the cheapest and most expensive company for your age bracket can be well over $200 for a week-long trip. If you’re 18–20, your options narrow to specific Enterprise, National, or Alamo locations, so confirm directly with the pickup counter before you book anything. And if your Chicago trip is mostly downtown, seriously consider skipping the rental altogether — the CTA will get you almost everywhere you actually want to go, and a car only earns its keep once you’re planning trips outside the city.
