Yes, you can rent a car in Puerto Rico if you're under 25, but it comes with significant challenges and extra costs. Major rental companies like Enterprise, Avis, and Hertz typically rent to drivers as young as 21, but they charge a Young Driver Surcharge—often an additional $25-$35 per day. Drivers under 21 will find it extremely difficult, though not entirely impossible, as a few local agencies might offer rentals to 18-20 year olds with very strict conditions and much higher fees.
The primary hurdle is the daily surcharge. If you're 21-24, budgeting for this non-negotiable fee is crucial. You must also possess a valid driver's license from your country of residence (a U.S. license is ideal) and a major card in your name for the security deposit; debit cards are often not accepted for young drivers.
Strategies to Reduce Costs:
The table below compares the general policies for drivers under 25 from major rental companies operating in Puerto Rico.
| Rental Company | Minimum Age to Rent | Typical Young Driver Fee (Ages 21-24) | Key Requirements & Notes |
|---|---|---|---|
| Enterprise | 21 | ~$25 per day | Must have a valid license; major credit card required. |
| Hertz | 21 | ~$27 per day | Fee varies by location and rental type. |
| Avis | 21 | ~$30 per day | Prepaid debit cards are not accepted for security holds. |
| Local/Independent Agencies | 18-21 (varies) | Varies; can be higher | Policies are less standardized; requires direct verification. |
In short, renting under 25 is feasible with careful planning and a budget that accommodates the unavoidable surcharges. Your best approach is to compare total costs, including all fees, from both international and reputable local companies.

Just went through this. I'm 23, and yeah, you can do it, but get ready for the "young driver fee." It slapped an extra $30 onto my daily rate. My advice? Call a couple of local rental spots directly. I found one in San Juan that was a bit more flexible on the hold they put on my card compared to the big names. Definitely use your own if it covers rentals to skip their pricey damage waiver.

As a frequent traveler, the key is meticulous comparison. The advertised base rate is irrelevant for drivers under 25. You must get a final quote that includes all mandatory fees. Focus on the total cost, not the daily rate. I recommend using rental comparison websites that have a filter for "young driver" to see the true price. Also, ensure your license has been valid for at least a year, as some companies have that requirement.

It's totally possible, but it's a budget-buster. The main thing is that debit card you use for everything? They probably won't take it. You need a real card for the security deposit. The fee for being under 25 is annoying, but it's just part of the deal. Pack your patience and read every line of the rental agreement so there are no surprises when you go to pick up the keys.

Focus on the financial logistics. The young renter fee is a fixed cost, but the Collision Damage Waiver (CDW) is where you can save. Before you book, call your card company. Many premium cards include primary rental insurance as a benefit. If yours does, you can confidently decline the rental company's CDW, potentially saving hundreds over the course of your trip. This single step is the most effective way to manage the overall cost of renting while under 25.
