Yes, you can rent a car in Portland at 20, but your options are limited and it will be significantly more expensive due to mandatory young renter fees. Major companies like Hertz, Enterprise, and Avis have policies allowing rentals starting at age 20, though specific franchise locations may have different rules. The primary challenge isn't finding a willing company, but budgeting for the additional daily surcharge, which is typically non-negotiable.
The most critical step is to call the specific rental location directly. Corporate policies can differ from individual franchisee rules. When you call, confirm three things: their minimum age , the exact daily young renter fee, and whether they accept debit cards or require a credit card. Many locations require a credit card in the renter's name for security.
You will need to present a valid driver's license from your country or state, and most companies require you to have held it for at least one year. They will also ask for proof of insurance or require you to purchase their coverage. Be prepared for a larger security deposit hold on your card.
The table below outlines the typical young renter fees and policies for major companies at Portland International Airport (PDX), though these are subject to change.
| Rental Company | Minimum Age | Typical Young Renter Fee (per day) | Credit Card Required? |
|---|---|---|---|
| Hertz | 20 | $25 - $35 | Usually Yes |
| Enterprise | 20 | $25 - $30 | Often Yes |
| Avis | 20 | $27 - $32 | Usually Yes |
| Budget | 20 | $27 - $32 | Usually Yes |
| Fox Rent A Car | 20 | $20 - $30 | Varies by Location |
| Sixt | 20 | $25+ | Varies by Location |
Booking through cost-comparison websites can sometimes bundle or slightly reduce these fees. The key is transparency—factor in the base rate, taxes, fees, and the young renter surcharge to understand the true total cost. Renting from an airport location often provides more consistent adherence to corporate age policies compared to off-airport neighborhood offices.

It's possible, but get ready for some extra steps and fees. You'll want to stick with the big names like Hertz or Enterprise. My advice? Don't just book online. Pick up the and call the actual location you want to rent from. Ask them point-blank: "What's your daily under-25 fee?" Also, make sure you have a credit card; a debit card can cause headaches. It’s totally doable, just plan for a higher cost.

I rented a car here last year when I was 20. I used the Enterprise at the airport. The process was smooth, but the young driver fee was a surprise—it added about $30 a day to the cost. They were strict about needing a card for the deposit. The agent was helpful, but I wish I’d known to call ahead to get the full fee breakdown. It worked out fine, just budget for that extra charge. It definitely beats trying to get around Portland without a car.

Focus on the total cost, not just the advertised daily rate. The young renter fee is the main financial hurdle. You must be 20, but the fee applies until you're 25. This surcharge is on top of all other taxes and fees. To manage this, use the rental company's official website to get a quote and look for the fee disclosure in the fine print. Compare the final totals, not the starting prices. Companies like BuddyLo or U-Save might have lower base rates but always confirm their age by phone.

Absolutely, but your choices narrow. The major players at PDX are your best bet for clear policies. Beyond the fee, consider the vehicle class. Renting a standard economy car might have fewer restrictions than a premium SUV. Also, look into non-traditional options like Turo; some individual car owners on the platform set their minimum age to 21, but it's worth checking as policies vary. Regardless of where you book, having your own liability from a personal auto policy will significantly reduce the cost of coverage they try to sell you at the counter.
