The main rental companies in Fremont and where to find them
Fremont has rental desks at Norman Y. Mineta San José International Airport (SJC), about 20 miles south, and at several off-airport locations around the city itself. The airport location gives you the widest choice of companies — Enterprise, Hertz, Budget, Avis, and National all operate there — but you'll pay an airport concession fee on top of the daily rate, usually 10 to 15 percent depending on the rental company.
Off-airport rentals in Fremont proper are cheaper because they skip that fee. Enterprise and Budget have standalone locations in central Fremont; you can find their addresses and phone numbers through their websites or by searching "[company name] car rental Fremont CA." Costco Travel also offers discounted rates through Hertz if you're a member, though you book through Costco's travel portal rather than calling Hertz directly.
If you're flying into SJC and want to avoid the airport fee, you can rent from an off-airport location instead — but you'll need ground transportation to get there first, which may cost more than the fee you're trying to avoid. The math usually favors the airport desk unless you're staying in Fremont for several days and can use public transit or a rideshare to reach an off-airport location.
Key Takeaways
- Airport rentals at SJC charge a concession fee of 10 to 15 percent on top of the daily rate, but offer the most company choices and the easiest pickup if you're flying in.
- Off-airport Enterprise and Budget locations in Fremont skip the airport fee but require you to arrange your own transportation to reach them.
- Daily rates vary by season, day of week, and how far ahead you book — weekend rates are typically higher than weekday rates, and booking two weeks early usually costs less than booking three days before.
- You'll need a valid driver's license, a credit card in your name, and proof of insurance (your own policy or the rental company's coverage) before you can pick up a car.
- Most companies charge extra for drivers under 25, additional drivers, GPS units, and fuel if you return the car with less than a full tank.
What documents and information you need to bring
Bring your valid driver's license — it must be current and match the name on your credit card. If your license is from outside the United States, bring your passport as well. The rental agent will scan both documents before you sign the rental agreement.
Bring a credit card in your name. The company will place a hold on it (usually $200 to $500 depending on the car size) to cover potential damage or fuel charges. Debit cards are rarely accepted for the hold, even if you have enough money in the account. If you're renting with someone else's credit card, most companies will refuse the rental or require that person to be present with ID.
Bring proof of insurance. This can be your own auto insurance card, a screenshot of your policy from your insurer's app, or a printed email confirmation. If you don't have insurance or your policy doesn't cover rentals, you can buy the rental company's damage waiver at pickup — this typically costs $15 to $25 per day and covers collision and theft. Read what it covers and what it doesn't before you agree; some waivers exclude damage from off-road driving or from towing.
How rates differ by season, day, and how far ahead you book
Fremont rental rates climb during summer (June through August), around major holidays, and during large events in the Bay Area. A compact car might rent for $35 to $50 per day in January but $60 to $90 per day in July. Weekend rates are consistently higher than weekday rates — a Friday or Saturday rental costs 20 to 40 percent more than the same car on a Tuesday or Wednesday.
Booking two to three weeks ahead usually locks in a lower rate than booking a week before or a few days before. However, most rental agreements let you cancel or modify your reservation up to 24 hours before pickup without penalty, so booking early doesn't lock you in if your plans change. If rates drop after you book, you can rebook at the lower rate and cancel the original reservation.
One-way rentals (picking up in Fremont and returning in another city) cost significantly more than round-trip rentals, sometimes 50 to 100 percent more. If you need a one-way rental, compare the one-way price to the cost of a round-trip rental plus a one-way flight or train ticket back to Fremont; sometimes the latter is cheaper.
Damage waivers, insurance, and what happens if you get in an accident
Your own auto insurance may cover rental cars, but not always. Call your insurer before you rent and ask whether your policy covers collision, theft, and liability on a rental vehicle. If it does, bring your insurance card to the rental desk and decline the rental company's damage waiver — you'll save $15 to $25 per day. If your policy doesn't cover rentals or you don't have insurance, buy the rental company's waiver at pickup.
The waiver typically covers collision damage and theft but excludes damage from off-road driving, racing, or towing. It also usually excludes damage to the windshield, tires, undercarriage, and interior (stains, burns, rips). Read the waiver document before you sign; the rental agent will explain what's covered and what isn't.
If you get in an accident, stop and call the police if anyone is injured or if there's significant damage. Get the other driver's name, phone number, address, driver's license number, and insurance information. Take photos of all vehicle damage, the accident scene, and the other vehicle. Call the rental company's claims line when ready — the number is on your rental agreement. Don't admit fault or sign anything except the police report. The rental company will handle the claim with the other driver's insurance or with their own coverage.
Fuel options and what to watch for at return
Most rental companies offer three fuel options: prepay for a full tank at pickup (you keep any unused fuel), return the car with a full tank yourself, or return it with whatever fuel is in it and pay the company's per-gallon rate for what's missing. The prepay option is usually the cheapest if you'll use most of the tank. Returning with a full tank yourself is cheapest if you find a gas station near the rental location. Returning with partial fuel is the most expensive option because the company charges $6 to $10 per gallon, roughly double the market rate.
When you return the car, the agent will inspect it for damage, check the mileage, and note the fuel level. Take photos of the car's condition before you leave the lot and keep your rental agreement and receipt. If the company later charges you for damage you didn't cause, you'll have documentation to dispute it. Most companies give you 30 days to contest damage charges; after that, the charge sticks.
Age restrictions and additional driver fees
Drivers under 25 pay a daily surcharge, typically $15 to $25 per day, at most rental companies. Some companies won't rent to drivers under 21 at all. If you're under 25, call ahead to confirm the company's age policy and the surcharge amount before you book.
Adding a second driver costs $10 to $15 per day at most companies, though some include one additional driver for free. The second driver must have a valid license and be present at pickup to sign the rental agreement. If you're renting with a spouse or partner, ask whether they can drive for free; policies vary by company.
GPS units (if the car doesn't have built-in navigation) cost $5 to $15 per day. Most modern smartphones have free navigation apps like Google Maps or Apple Maps that work just as well; use your phone instead and save the fee. If you need a phone mount, bring your own or buy one for $10 to $20 at a gas station or drugstore.
Comparing airport versus off-airport pickup and what each costs
| Pickup Location | Companies Available | Concession Fee | Best For |
|---|---|---|---|
| SJC Airport | Enterprise, Hertz, Budget, Avis, National | 10–15% of daily rate | Flying in; want maximum company choice |
| Fremont off-airport (Enterprise, Budget) | Enterprise, Budget | None | Staying in Fremont; have ground transportation |
| Costco Travel (Hertz) | Hertz only | None; discounted rate | Costco member; booking in advance |
The airport concession fee adds up quickly on longer rentals. A $50 per day compact car with a 12 percent fee costs $56 per day, or an extra $72 over a three-day rental. If you're staying in Fremont and can use a rideshare or public transit to reach an off-airport location, the savings may justify the extra trip. If you're flying in and need the car when ready, the airport desk is worth the fee because you avoid waiting for ground transportation.
Frequently Asked Questions
Can I rent a car if I have an international driver's license?
Yes, but you'll need both your international license and your passport. Some companies also require an International Driving Permit (IDP), which you obtain from your home country's automobile association before you travel. Call the rental company ahead of time to confirm what documents they need; requirements vary.
What happens if I return the car late?
Most companies charge an hourly rate for late returns — typically $15 to $30 per hour for the first few hours, then a full day's rate if you're more than a few hours late. Some companies are stricter than others. Call the rental location as soon as you know you'll be late and ask what the charge will be; they may waive it if you call ahead.
Can I rent a car with a debit card instead of a credit card?
Most companies won't accept a debit card for the damage hold because they can't verify funds the same way they can with a credit card. A few companies will rent to you with a debit card if you show proof of insurance and a return airline ticket, but this is rare. Bring a credit card if you have one; if you don't, call the rental company ahead of time to ask whether they'll accept a debit card.
Do I need to buy the rental company's insurance if I have my own auto policy?
Not if your policy covers rental vehicles. Call your insurer and ask specifically whether collision, theft, and liability are covered on rentals. If they are, bring your insurance card to the rental desk and decline the company's waiver. If your policy doesn't cover rentals or you don't have insurance, buy the rental company's coverage at pickup.
What's the difference between a compact car and a midsize car, and does it matter for my trip?
A compact car (like a Honda Civic) is smaller, uses less fuel, and costs less per day but has less trunk space and rear legroom. A midsize car (like a Toyota Camry) has more space and comfort but costs $5 to $15 more per day and uses more fuel. For a solo trip or two people with light luggage, a compact is fine. For a family or a road trip with multiple bags, a midsize is worth the extra cost.
