What Does the SeaTac Airport Parking Garage Map Look Like? (Floor-by-Floor Guide)

The SEA parking garage is a multi-level structure where most floors serve General Parking and Floor 4 is set aside for Reserved Parking. Here is a floor-by-floor breakdown based on Port of Seattle information (checked October 2026). The Port says Reserved Parking expands to Level 5 on 13 October 2026, so follow the signs on arrival.

The skybridge connects the garage to the main terminal between Concourse B and Concourse C. From there, follow signage to reach any concourse — Concourses A, B, C, and D are all accessible from the central terminal. The North Satellite and South Satellite gates are reached via underground inter-terminal trains after clearing security.

Floor 1 also houses the free rental car shuttle, which runs 24/7. Off-site shuttle operators drop passengers on Floor 3 in the Courtesy Vehicle area — this is where you will be picked up when returning from the terminal.

Where Is the SeaTac Airport Parking Garage Located?

The main parking garage sits directly adjacent to the terminal building at Seattle-Tacoma International Airport, in the city of SeaTac, Washington. The garage entrance is accessed via Airport Expressway South, which loops off International Boulevard (State Route 99 / Pacific Highway South).

The garage is a single, connected structure, not multiple scattered lots. It serves all concourses through one terminal entry point via the skybridge. Signage inside the garage is clear, with color-coded lane guidance. White lanes lead to Reserved Parking. Blue lanes direct drivers to General Parking. Follow overhead signs from the moment you enter the structure.

The Cell Phone Lot is separate. It sits on the Off Airport Expressway, south of the terminal, and is completely free. It is the right choice if you are waiting to pick someone up and do not want to pay for the garage.

How Do You Get to SeaTac Airport Parking? (Driving Directions from I-5 and WA-99)

The garage is straightforward to reach from either Interstate 5 or State Route 99. Before you leave, check real-time traffic on Waze — the SEA Gateway Project roadway improvements are still underway in 2026 and may cause brief detours near the terminal frontage.

From I-5 (northbound or southbound):

1. Take Exit 154B for State Route 518 West toward Seattle-Tacoma International Airport.
2. Follow SR-518 west to the airport exit ramp.
3. Take Airport Expressway South and follow signs to the parking garage.

From SR-99 / International Boulevard:

1. Head north or south on International Boulevard (SR-99).
2. Turn onto S 170th St or use the Airport Expressway interchange — follow green parking signs.
3. Enter the garage from the Airport Expressway South ramp.

Drivers coming from West Seattle or Burien can also use State Route 509, which connects directly to the airport area. From the Eastside (Bellevue, Renton), take Interstate 405 south to SR-518 west. GPS navigation works reliably here — enter "Seattle-Tacoma International Airport Parking" and most apps route correctly to the garage entry.

What Is the Difference Between Reserved Parking and General Parking at SEA?

Reserved Parking guarantees you a space on Floor 4 of the garage (expanding to Level 5 on 13 October 2026). You book on the Port's ReserveSEA site at least 6 hours before entry and up to 120 days ahead, receive a QR code, and use a dedicated entry lane, with no circling required. General Parking is first-come, first-served on the other floors and cannot be reserved.

• Reserved Parking (Floor 4): $47/day | No posted weekly rate (7 days = $329) | Overstay $10/hour | Guaranteed space | QR code entry | Dedicated lane
• General Parking (other floors): $8/hr | $37/day max | $222/week | No reservation possible | Standard self-park

Reserved Parking costs $10/day more than General Parking. For a one-week trip, the gap is $107 ($329 vs. the $222 General Parking weekly rate). The main benefit is certainty, especially useful during holiday travel or for early-morning departures when the garage fills quickly.

Shuttles differ: Fox Parking SeaTac and the Seattle Airport Marriott run free 24/7 shuttles, Evods Parking at Spark by Hilton runs every 30 minutes around the clock, and Motel 6 runs only 7 AM to 10 PM. Rates below are for a 7-day stay booked ahead and change by date. For a full deep-dive on shuttles and timing, see our guide to SeaTac airport parking shuttle services.

The Seattle Airport Marriott is the closest lot Triply sells, listed 0.9 miles from SEA, with a free shuttle every 15 minutes around the clock. Motel 6 is the cheapest at about $9/day, but its shuttle stops between 10 PM and 7 AM. Fox Parking SeaTac at about $12/day is the lowest-priced option with a free 24/7 shuttle, and Evods Parking at Spark by Hilton is a valet lot with a 3-day minimum booking.

What Special Parking Options Are Available at SEA? (EV, Over-Height, ADA, Motorcycle)

The SEA garage offers several specialized parking options beyond standard stalls. Here is what is available and where to find it.

EV Charging

The garage has 94 free Level 2 EV charging stalls: 64 on Floor 7 (General Parking, rows E and F) and 30 on Floor 4 (Reserved Parking). The charge itself is free; you only pay the standard parking rate. Stalls are first come, first served and cannot be reserved. If you prefer to plan ahead, the ChargePoint app for EV drivers can help you locate charging near SEA before you arrive. Among the off-site lots Triply sells, Fox Parking SeaTac offers a separate Valet + Charging rate.

ADA / Accessible Parking

Accessible parking stalls are on Floor 5 (General Parking) and Floor 4 (Reserved Parking). No advance reservation is required for the General Parking accessible stalls; they operate on a first-come basis at the General Parking rate.

Over-Height Vehicles

The garage has a height limit of 6'10". Over-height vehicles, such as tall vans or trucks with roof racks, use a separate 78-stall outdoor lot (entrance off S 182nd St and International Blvd), first come, first served, at General Parking rates. Off-site, the Seattle Airport Marriott lot takes standard vehicles only.

Is It Cheaper to Book Off-Site Parking Near SeaTac Airport?

Yes. Off-site lots cost significantly less than parking in the on-site garage. Parking at Motel 6 at about $9/day costs about 75% less than General Parking at $37/day. For a seven-day trip, that is about $66 before tax vs. the $222 weekly rate, a saving of about $156.

• On-site General Parking: $37/day max ($222/week); garage attached to terminal, no shuttle needed
• On-site Reserved Parking: $47/day; guaranteed Floor 4 space, booked on ReserveSEA, QR code entry
• Off-site, Motel 6 and Fox Parking SeaTac: about $9 to $12/day; free shuttle (Motel 6 only 7 AM to 10 PM)
• Off-site, Evods Parking at Spark by Hilton and Seattle Airport Marriott: about $16 to $19/day; 24/7 shuttles, closest lots (1 mi and 0.9 mi)

The trade-off with off-site parking is the shuttle ride. Add 10-20 minutes each way to your travel time. Shuttle frequency varies: every 15 minutes at the Seattle Airport Marriott, every 15-20 minutes or on demand at Fox Parking SeaTac, every 30 minutes at Evods, and once an hour (7 AM to 10 PM) at Motel 6. Plan to arrive at the lot at least 30 minutes earlier than you would for the on-site garage. Budget travelers flying from Concourse B (Southwest, JetBlue) or Concourse C (Alaska Airlines) will find the skybridge arrival quick once the shuttle drops them on Floor 3.

Construction is also a factor in 2026. The SEA Gateway Project is improving roadway and terminal frontage access, while the C Concourse expansion ($260M) targets substantial completion in Q2 2026. The parking garage itself remains fully operational throughout all construction. Roadway signage is updated regularly, but budget a few extra minutes for navigation during peak periods near the terminal. For travelers doing overnight trips, compare the math using our guide to Seattle Airport long-term parking rates and lots.

Bottom line: The SEA airport parking garage is convenient and well-located, but off-site lots cost about 49% to 75% less per day than General Parking. Book in advance, especially for Reserved Parking on Floor 4, to hold your space and avoid surprises on travel day.
