How do walk-up and local off-airport renters access the SeaTac Rental Car Facility without arriving on a flight?

For local renters or walk-up customers not arriving via a flight at Seattle-Tacoma International Airport, accessing the Rental Car Facility requires using the ground-level public entrances rather than the airport train. The primary street address for GPS navigation is 3150 S 160th St, SeaTac, WA 98188. If you are driving and dropping off a vehicle, approach the facility via International Boulevard and turn onto S 160th St. There are 2 designated local renter drop-off lanes located on the ground floor near the north entrance, clearly marked with signage for 'Local Return / Off-Airport Drop-Off'. Parking is strictly limited to 15 minutes in these active drop-off zones. For pedestrians, rideshare users, or those being dropped off, there is a dedicated walk-up entrance located on the east side of the building along 24th Avenue S. This entrance provides direct stair and elevator access to the second-floor customer service lobby. Rideshare drop-offs are permitted at the 24th Avenue S entrance roundabout. Once inside the building, local renters proceed to the same consolidated service counters as arriving airline passengers. Allow approximately 5 to 10 minutes to walk from the 24th Avenue S entrance to the rental counter area. Avoid using the Airport Transit Station walkway, as it requires a valid airline boarding pass or airport badge to cross the security threshold.
