What you need to rent a car in San Juan

To rent a car in San Juan, you need a valid driver's license, a credit card in your name, and proof of insurance — either your own policy or the rental company's coverage. Most major rental companies (Enterprise, Hertz, Avis, Budget) have desks at Luis Muñoz Marín International Airport, in Old San Juan, and in the Condado neighborhood. You can reserve online or by phone before you arrive, which usually locks in a lower rate than walking up to the counter.

Your driver's license must be valid for the entire rental period. If your license is from outside the United States, bring an International Driving Permit (IDP) along with it — Puerto Rico recognizes both, but some rental companies ask for the IDP as a secondary form of ID. You'll also need to be at least 21 years old; most companies charge an extra daily fee (typically $15 to $25) if you're under 25.

The credit card must be in your name and have enough available credit to cover the estimated rental cost plus a hold for damage. Some companies place a hold of $200 to $500 on top of your reservation. Debit cards are rarely accepted, even if you have a damage waiver.

  • Collision damage waiver (CDW) through the rental company typically costs $12 to $20 per day and covers damage to the rental vehicle.
  • Puerto Rico drives on the right side of the road, and many streets in Old San Juan are narrow, one-way, and steep — parking is tight and paid.

Where to pick up and drop off a rental car

Luis Muñoz Marín International Airport (SJU) is the most convenient pickup location if you're flying in, but it's also the most expensive. All major rental companies have desks in the baggage claim area on the ground floor. Pickup is fast — usually 10 to 15 minutes after you've collected your luggage — but rates here run 15 to 30 percent higher than off-airport locations because the airport charges rental companies a concession fee.

Old San Juan (the historic district) has several rental offices within walking distance of the cruise ship terminal and the main plazas. Hertz, Enterprise, and Budget all have locations on Calle Fortaleza or nearby streets. Rates here are typically lower than the airport, and you can walk around the neighborhood while you wait for paperwork to be processed. The trade-off is that Old San Juan has limited parking, so returning a car here means navigating narrow streets and paying for a spot while you complete the return paperwork.

Condado, the beachfront tourist district, has Enterprise and Hertz locations near the major hotels. Pickup and return here are usually faster than Old San Juan because there's more parking, and rates fall between airport and Old San Juan prices. If you're staying in Condado and don't need a car when ready, this is often the best choice.

One-way rentals (picking up at the airport and dropping off in Old San Juan, for example) are possible but usually cost $30 to $75 extra. If you're renting for just a day trip, returning to your pickup location saves that fee.

Insurance and damage coverage options

Your own auto insurance may cover rental cars, but check your policy before you travel — many policies exclude rentals in Puerto Rico or require you to pay out of pocket and file a claim later. If your policy doesn't cover rentals, or if you prefer not to use it, the rental company will offer you a collision damage waiver (CDW) for $12 to $20 per day. This covers damage to the rental car from collisions, theft, or vandalism, though you'll still pay a deductible (usually $500 to $1,000) if there's a claim.

Credit card companies sometimes cover rental car damage if you charge the full rental to that card. Call your card issuer before you book to confirm coverage and what it includes — some cards cover only collision, not theft or vandalism. If your card covers rentals, you can decline the rental company's CDW and save the daily fee, but you'll be responsible for paying the rental company first and then filing a claim with your card issuer.

Liability insurance (coverage if you damage someone else's property or injure another person) is required by Puerto Rico law and is included in all rental agreements. Your own auto insurance usually covers liability in rentals, but confirm this with your insurer. If it doesn't, the rental company will add it to your bill — typically $10 to $15 per day.

Decline any add-ons like roadside information, GPS rental, or additional liability coverage unless you specifically need them. Your phone's GPS works fine in San Juan, and roadside information is rarely necessary for a short rental.

Rates, fees, and what to expect at checkout

Daily rental rates in San Juan range from $25 to $80 for a compact economy car, depending on the season and how far in advance you book. Summer (June through August) and winter holidays are peak season, with rates at the high end. September through November is slower, with lower rates. Booking online at least a week in advance usually saves 20 to 40 percent compared to booking at the counter.

The quoted daily rate does not include taxes, which add about 16 percent to your bill in Puerto Rico (the sales tax is 11.5 percent, plus a 4.75 percent rental tax). A $50-per-day car will cost roughly $58 per day after tax. Fuel is not included — you pay for gas when you return the car, or you can prepay for a full tank at the time of rental (usually a better deal if you'll return the car with less than a full tank).

At pickup, you'll walk around the car with a rental agent and note any existing damage on the contract. Take photos of the car's condition with your phone before you drive away — this protects you if the company claims you caused damage you didn't. At return, the agent will inspect the car again. If there's new damage and you didn't purchase CDW, you'll be charged for repairs. If you did purchase CDW, you'll pay the deductible.

Fuel charges can surprise you if you don't plan ahead. If you prepay for a full tank and return the car with a quarter tank, you lose that money. If you don't prepay and the tank is low at return, the company will charge you for a full tank at a markup (often $5 to $8 per gallon, compared to $2 to $3 at a gas station). Return the car with a full tank to avoid this.

Driving in San Juan and Puerto Rico

Puerto Rico drives on the right side of the road, and the speed limit on highways is 65 mph unless posted otherwise. In San Juan proper, limits are 25 to 35 mph. Traffic laws are enforced, and speeding tickets start at $100. Seat belts are required for all passengers, and using a phone while driving is illegal.

Old San Juan's streets are narrow, steep, one-way, and confusing if you don't know them. Parking is metered and costs $0.50 to $2.00 per hour depending on the zone. If you're renting just to explore Old San Juan, consider a taxi or ride-share instead — the stress and parking hassle often outweigh the convenience. If you do drive there, arrive early to find a spot and allow extra time for navigation.

Outside Old San Juan, roads are generally well-maintained and clearly marked. The PR-52 highway connects San Juan to the south coast and is fast and straightforward. The PR-22 toll road heads west toward Arecibo. Tolls are paid at toll plazas with cash or a T-Pass (a prepaid toll card you can rent from the car rental company for a small fee). If you don't have a T-Pass and try to pass through a toll plaza, you'll be photographed and billed later — expect a $5 to $10 toll plus a processing fee.

Parking at hotels and attractions is usually free, but validate your ticket at the business. Street parking in residential areas is free but can be hard to find. Never leave valuables visible in the car, and avoid parking in unfamiliar neighborhoods after dark.

Booking online versus at the counter

Booking online before you arrive locks in a rate and guarantees a car in your chosen category. Walk-up rates at the rental counter are almost always higher — often 20 to 40 percent more — because the company charges more for same-day bookings. If you book online and the rate drops before your trip, you can usually rebook at the lower rate (check the rental company's cancellation policy first).

Use a price comparison site like Kayak, Autoslash, or Priceline to see rates from multiple companies at once. Enter your pickup and return dates, location, and driver age, then sort by total price (not daily rate, since taxes and fees vary). Read the fine print on each quote — some include CDW, some don't; some have strict cancellation policies, others don't.

Book directly with the rental company's website if you have a loyalty program or corporate discount code. These often beat third-party sites. Enterprise Plus members, for example, can skip the counter entirely and go straight to their car — useful if you're in a hurry.

Frequently Asked Questions

Do I need an International Driving Permit to rent a car in San Juan?

No, but it's recommended if your license is not in English. Puerto Rico recognizes valid driver's licenses from all countries, but some rental companies ask for an IDP as a secondary form of ID. An IDP is inexpensive and takes a few minutes to get from your local auto club before you travel, so it's worth having if your license is in another language.

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

Yes, but you'll pay an underage driver fee of $15 to $25 per day. You must be at least 21. Some luxury or specialty vehicles have higher minimum age requirements (25 or 30), so check the listing when you book.

What happens if I get a speeding ticket or parking ticket in a rental car?

The rental company will be notified and will bill you for the ticket plus a processing fee (usually $15 to $25). Pay any ticket you receive when ready if possible — ignoring it will result in additional fines and may prevent you from returning the car. If you believe the ticket is unfair, you can contest it in Puerto Rico traffic court, but this requires staying on the island or hiring a local attorney.

Is it cheaper to rent a car or use taxis and ride-shares in San Juan?

For a single day or short trips, ride-shares (Uber and Lyft operate in San Juan) are usually cheaper and less stressful than renting. A ride from the airport to Condado costs $15 to $25. If you're staying for three or more days and plan multiple trips outside Old San Juan, a rental car becomes cheaper. Calculate your expected rides and compare the total cost to a daily rental rate before you decide.

Can I rent a car if I don't have a credit card?

No. All rental companies require a credit card in your name to hold the reservation and cover potential damage charges. Debit cards are not accepted. If you don't have a credit card, ask the rental company whether a family member can provide theirs — some companies allow this if that person is present at pickup.
