The main rental companies in Portland and how they differ

Portland has rental desks at Portland International Airport (PDX), downtown on Southwest Alder Street, and in several neighborhoods. The largest chains — Enterprise, Hertz, Budget, and Avis — operate multiple locations, while regional companies like Costco Travel (for members) and local operators like Getaround and Turo offer alternatives with different pricing and pickup models.

Airport rentals cost more than off-airport locations because the airport charges concession fees that companies pass to you. A car rented at PDX might run 15 to 25 percent higher than the same car from a downtown lot. If you're flying in, check whether picking up a few miles away saves enough to justify the extra drive time. Downtown Portland locations are walkable from transit and hotels, which matters if you don't have a ride to the lot.

The rental agreement you sign at pickup specifies the daily rate, mileage limits (if any), fuel policy, and damage coverage. Read the damage section carefully — it describes what you pay for if the car gets scratched, dented, or damaged. Most companies charge a damage waiver fee (typically $15 to $30 per day) that limits your out-of-pocket cost if something happens.

Key Takeaways

  • Airport rentals cost 15 to 25 percent more than downtown Portland locations because of concession fees, so compare pickup locations before booking.
  • You need a valid driver's license, proof of insurance (yours or the rental company's), and a credit card in your name at pickup — bring all three documents.
  • Damage waivers ($15 to $30 per day) limit what you pay if the car is damaged, but read the agreement to understand what damage costs extra.
  • Fuel policies vary: some charge you per gallon if you return the car empty, others charge a flat rate, and some require you to return it full or pay a premium.
  • Mileage limits depend on the rental type and company; daily rentals often have unlimited miles, but weekly and monthly rates sometimes cap mileage or charge per mile over the limit.

What documents and payment method you need at pickup

Bring your valid driver's license, a credit card in your name, and proof of insurance. The credit card doesn't have to be charged — it's a hold to cover potential damage or fuel charges. Some companies accept debit cards, but most require a credit card and may hold a larger amount ($200 to $500) as a security deposit.

Proof of insurance can be your personal auto policy, your credit card's rental coverage (if it includes it), or the rental company's coverage. Check your personal policy or credit card benefits before you rent; if you're covered, you can decline the company's damage waiver and save money. If you're not covered, buy the company's coverage at pickup — it's cheaper than paying out of pocket for damage.

Some companies ask for a second form of ID (passport, military ID, or state ID) and your contact information. Have your phone number and email ready. If you're under 25, expect a young driver fee ($15 to $25 per day) added to your bill.

Daily, weekly, and monthly rates and what they include

Daily rates in Portland range from roughly $40 to $80 for an economy car, depending on the company, season, and how far in advance you book. Weekly rates are usually cheaper per day — booking for seven days might cost $200 to $350 total, or about $29 to $50 per day. Monthly rentals drop further, sometimes to $20 to $40 per day for a full month.

The rate includes the car, basic insurance (if you buy it), and roadside information from most companies. It does not include gas, tolls, parking fees, or traffic violations. Some companies charge extra for GPS rental (though most phones have maps built in) or additional drivers. Check the final quote before you confirm — it should list every fee.

Mileage limits vary. Daily rentals typically offer unlimited miles. Weekly and monthly rentals sometimes cap mileage at 100 to 150 miles per day; if you exceed it, you pay 15 to 25 cents per extra mile. Ask the company what mileage limit applies to your rental length before you book.

Fuel policies and how they affect your final bill

Most Portland rental companies use one of three fuel policies: full-to-full, full-to-empty, or prepay. Under full-to-full, you pick up the car with a full tank and return it full; if you don't, you pay the company's per-gallon rate, which is usually 30 to 50 percent higher than gas station prices. Under full-to-empty, you return the car empty and pay only for the gas you used. Under prepay, you buy a full tank upfront at a set price; if you return it with gas left, you don't get a refund.

Full-to-full is the most common and usually the cheapest if you return the car with a full tank. Full-to-empty works best if you'll use most of the tank. Prepay is rarely the best deal unless you know you'll use nearly a full tank and want to avoid the per-gallon markup. Ask which policy applies when you book, because it affects your total cost.

Damage waivers, insurance, and what you're responsible for

A damage waiver (also called a collision damage waiver or CDW) limits your liability if the car is damaged. Without it, you're responsible for the full repair cost, which can be thousands of dollars. With it, you typically pay a deductible ($500 to $1,500) and the company covers the rest. The waiver costs $15 to $30 per day.

Check whether your personal auto insurance or credit card covers rental cars before you buy the company's waiver. Many personal policies and premium credit cards include rental coverage; if yours does, you can decline the waiver and save money. Read the fine print — some policies exclude certain damage types or have mileage limits.

You're always responsible for traffic violations, parking tickets, and tolls, even if you buy a damage waiver. You're also responsible for damage caused by misuse — driving off-road, towing a trailer without permission, or driving under the influence. The rental agreement lists these exclusions. Return the car clean and undamaged to avoid extra charges.

Pickup and return locations around Portland

Portland International Airport (PDX) has rental desks in the baggage claim area. Downtown Portland has multiple locations on Southwest Alder Street and nearby. Neighborhoods with rental locations include Northeast Portland (near Lloyd Center), Southeast Portland (near the airport), and Beaverton (west of the city). Some companies offer one-way rentals, so you can pick up in Portland and drop off elsewhere; one-way fees vary but typically run $50 to $200 depending on distance.

Hours vary by location. Airport desks are usually open from early morning (5 or 6 a.m.) until late evening (11 p.m. or midnight). Downtown and neighborhood locations typically close by 6 p.m. and may have limited weekend hours. Check the company's website for the specific location's hours before you book, especially if you're arriving late or need to return early.

Some companies offer mobile pickup — you reserve online, and an employee brings the car to you at the airport or a nearby location. This service usually costs extra ($10 to $25) but saves time if you're in a hurry. Ask whether it's available when you book.

Booking online versus at the counter and timing

Booking online before you arrive locks in a rate and lets you compare companies side by side. Rates change daily, and advance bookings are usually cheaper than walk-up rates. Book at least a few days ahead if possible. If you book the day before or the day of, expect higher prices and fewer car options.

At the counter, you can negotiate or ask about upgrades, but the base rate is usually higher than online. If you book online and the counter offers a better rate, ask them to match it — some companies will. Pickup takes 10 to 20 minutes if you have all your documents; longer if you need to buy insurance or add services.

Return is usually faster than pickup — 5 to 10 minutes if the car is undamaged and the tank is full. The company inspects the car for damage, checks the mileage and fuel level, and processes your payment. Keep your receipt and the rental agreement for your records.

Frequently Asked Questions

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

Most Portland rental companies require a credit card in your name for the security hold. Some accept debit cards, but they typically hold a larger amount ($300 to $500) and may require additional ID or a deposit. Call the company before you book to confirm whether they accept debit cards.

What happens if I return the car late?

Late fees vary by company but typically run $25 to $50 per hour or a percentage of the daily rate. If you're running late, call the rental location as soon as you know — some companies waive or reduce the fee if you notify them in advance. Check your rental agreement for the exact late fee policy.

Can I add another driver after I pick up the car?

Yes, but you'll need to return to the rental location with the additional driver and their valid license. The company will add them to the agreement and may charge an additional driver fee ($10 to $15 per day). It's cheaper to add them at pickup if you know in advance.

What if the car breaks down while I'm renting it?

Call the rental company's roadside information number (it's on your rental agreement). They'll send a tow truck or replacement car at no cost to you. Keep the receipt for any expenses and report the breakdown to the company in writing within 24 hours.

Do I need to buy extra insurance if I already have auto insurance?

Check your personal policy first — it may cover rental cars. If it does, you can decline the company's damage waiver and save $15 to $30 per day. If your policy doesn't cover rentals or you're unsure, buy the company's coverage at pickup to protect yourself from repair costs.
