Yes, you can rent a car at 21 in Maryland, but it comes with significant restrictions and extra costs. Unlike the standard rental age of 25, Maryland state law allows rental companies to rent to drivers as young as 18, but most major companies set their minimum age at 21. The primary challenge is the Young Renter Fee (also called an underage surcharge), which is a daily charge that can substantially increase your rental cost. Additionally, you'll face limited vehicle choice, typically restricted to economy or compact car classes, and you must meet stricter requirements, like possessing a valid driver's license for a minimum period.
The key factor is the rental company's specific policy. While the law permits it, companies have their own rules. You will almost always be required to present a valid, non-provisional driver's license that you've held for at least one year, and a major credit card in your name is mandatory; debit cards or cash are generally not accepted for young renters. The underage surcharge is the biggest hurdle. This daily fee can range from $15 to $50 or more, depending on the company and location.
Here is a comparison of policies from major rental companies at Maryland locations like BWI Airport:
| Rental Company | Minimum Age to Rent | Young Renter Fee (Under 25) | Vehicle Class Restrictions for Under-25 |
|---|
| Enterprise | 21 | ~$25 per day | Typically excludes premium, luxury, SUVs, and minivans |
| Hertz | 21 | ~$27 per day | Often limited to Compact through Full-size cars |
| Avis | 21 | ~$27 per day | Similar restrictions on larger vehicle types |
| Budget | 21 | ~$25 per day | Usually cannot rent specialty or high-value vehicles |
| Alamo | 21 | ~$30 per day | Restrictions apply to premium car categories |
To successfully rent, plan ahead. Book online and be prepared to show your license and a credit card. Always ask the rental agent to confirm the total cost, including all taxes and the young renter fee, before you finalize the agreement. Renting at 21 is possible, but it requires careful budgeting for the added expenses.
