Yes, you can rent a car at 20 in San Francisco, but your options will be limited and significantly more expensive due to age-related policies. The standard minimum age to rent a car in the U.S. is 25, but most major rental companies make exceptions for drivers aged 20-24, charging a mandatory Young Renter Surcharge (often called an underage fee). This daily fee can add $25-$50 to your rental cost. Availability is also restricted; you will typically only be able to rent economy or compact vehicle classes, and luxury, SUV, or premium car rentals are almost always prohibited.

The key to a successful rental is preparation. You must present a valid driver's license that you've held for at least one year, a major credit card in your name (debit cards are rarely accepted for young drivers), and proof of any required insurance. Renting from an airport location often provides more flexibility for under-25 drivers compared to neighborhood branches. Be sure to book directly through the company's website or by phone to confirm the exact policy and fees for your specific dates, as these can change and are non-negotiable. Always factor the young renter surcharge into your total budget, as it can double the base cost of a rental.
