Portland to Seattle is roughly 145 miles by road — a drive of about 2.5 to 3 hours on a clear day — making it one of the most traveled relocation routes in the Pacific Northwest. A typical household move on this corridor runs $1,500–$5,500, depending on home size, time of year, and the services you need. The biggest change this move brings is not the distance or the rain — it's the jump in cost of living, particularly housing, set against the fact that Washington has no state income tax.
How far is Portland to Seattle, and how long does a move take?
The straight-line distance is approximately 145 miles, with driving distance slightly longer via I-5 North — typically 175–180 miles depending on your specific origin and destination addresses. A moving truck (traveling slower than a passenger vehicle, with a potential rest stop) should plan for 3 to 4 hours of drive time under normal conditions.
That said, "one day" doesn't always mean one smooth day. I-5 through Tacoma and into Seattle can stack up quickly, especially on summer Fridays or around holidays. If your move falls between May and September, build buffer time into your schedule. A departure from Portland before 7 a.m. puts the truck ahead of the afternoon crawl through Tacoma.
What a Portland-to-Seattle move costs
Because this is an interstate move (Oregon to Washington), it is regulated differently than a local move, and pricing is typically based on weight and distance rather than hourly rates. Here are ballpark ranges:
| Home Size | Estimated Moving Cost |
|---|---|
| Studio / 1-bedroom | $1,500 – $2,500 |
| 2-bedroom | $2,500 – $3,800 |
| 3-bedroom | $3,500 – $5,500 |
| 4+ bedroom | $5,000 – $8,500+ |
These are typical market estimates and will vary based on the volume of your shipment, access at both locations, packing services, season, and current fuel costs. Always request a binding estimate in writing before committing to any mover.
A few cost factors specific to this route:
- Season is one of the inputs. Quotes for June through August dates can differ from quotes for late September through April dates. Ask each mover for the same move priced on two or three different dates and compare them.
- Ask about delivery windows. On an interstate move, even a short one like this, movers may quote a delivery window rather than a guaranteed same-day delivery. Clarify this upfront. Over a distance of about 145 miles, same-day or next-day delivery may be possible, but the date or window that counts is the one written on your bill of lading.
- Valuation coverage. On an interstate move, Full Value Protection applies automatically, meaning the mover must repair, replace or pay the replacement value of what is damaged. The free Released Value option (60 cents per pound per article) applies only if you sign a written waiver choosing it. Valuation is the mover's liability level, not insurance, so ask each mover to explain both options in writing.

Portland and Seattle side by side: rent, home prices and tax
Seattle is meaningfully more expensive than Portland across almost every category — but Washington's zero income tax can partially offset that gap for higher earners.
| Category | Portland, OR | Seattle, WA |
|---|---|---|
| Cost-of-Living Index | 105 | 111 |
| Median 2BR Rent | $1,850/mo | $2,850/mo |
| Median Home Price | $510,000 | $850,000 |
| State Income Tax | Up to 9.9% | 0% (none) |
| City Population | 652,503 | 737,255 |
Measured against the 2024 federal price index (U.S. = 100), the Portland area sits at 105 and the Seattle area at 111 — Seattle runs about 5% to 6% more expensive than Portland on a broad basket of goods and housing. The rent difference alone — $1,000/month more for a comparable two-bedroom — belongs in your budget before the move, not after.
The income tax change works in the other direction. Someone earning $100,000 in Portland pays several thousand dollars a year in Oregon state income tax, and Washington charges none. For a person relocating to a tech or professional job in Seattle, that saving narrows the effective cost-of-living gap.
Seattle's grey against Portland's wildfire smoke
The short version: similar, but with a little more grey and a little less wildfire smoke.
Both cities share the classic Pacific Northwest pattern — mild, dry summers and cool, wet winters. Portland summers typically reach the 70s–80s°F; Seattle's summers tend to sit in the mid-70s, a degree or two cooler. Both cities see rare snowfall in winter, and neither handles it gracefully when it does fall.
One practical note for the move itself: Portland residents in late summer sometimes contend with regional wildfire smoke that can significantly reduce air quality. Seattle isn't immune — smoke from Eastern Washington and Oregon fires can drift in — but patterns vary year to year. If you're sensitive to air quality, late summer is worth thinking about when scheduling your move date.
Seattle neighborhoods, from Capitol Hill to West Seattle
Seattle's neighborhoods vary dramatically in character, price, and commute profile. While neighborhood data can change quickly in a growing city, here's a practical framework:
- Capitol Hill & First Hill — Dense, walkable, vibrant. A good fit if you work in healthcare or downtown.
- Ballard — A former Scandinavian fishing village with a strong local identity. More relaxed pace, excellent restaurant scene, increasingly family-oriented.
- Fremont — Quirky, artsy, and close to the water. Good bike infrastructure if you want to commute that way.
- Queen Anne — Stunning views, quieter, and close to Seattle Center. Suits families and professionals.
- West Seattle — More affordable (relative to Seattle standards), with a neighborhood feel and great waterfront access.
- Bellevue / Eastside — If you're working in tech on the Eastside, living across the lake cuts commute time dramatically and may offset the higher rents.
Take at least one exploratory trip before committing to a lease or purchase. Seattle's topography — hills, water, bridges — means that two neighborhoods that look close on a map can feel very far apart during rush hour.
Washington paperwork, Puget Sound traffic and the ORCA card
A few things worth knowing on this route:
- Register your vehicle. Washington requires you to register your vehicle and get a WA driver's license within 30 days of establishing residency. Put it on the calendar for your first week.
- Seattle's traffic is no joke. The city's geography (hemmed in by Puget Sound and Lake Washington) means there are limited corridors and bridges. Know your commute route before you sign a lease.
- No income tax, but check other taxes. Washington has no state income tax, but does have a higher sales tax than Oregon (Oregon has none). Work through the math with your own spending habits.
- ORCA card, day one. Seattle's transit card covers buses, light rail, and ferries. Get one as soon as you arrive.

Choosing a carrier for the I-5 corridor
This is an interstate move, which means your mover must have a USDOT number and MC (motor carrier) authority issued by the Federal Motor Carrier Safety Administration (FMCSA). Check both before you book anyone.
Beyond licensing:
- Collect three binding estimates in writing. Not ballparks — written binding estimates based on an in-home or video survey of your belongings.
- Read the reviews on independent review sites. Look for consistent feedback about communication, care with belongings, and delivery timing — not just price.
- Ask specifically about this route. Movers who run Portland–Seattle regularly will know the quirks: Seattle delivery logistics (narrow streets, elevator reservations in apartments, permit requirements for parking a truck), timing, and traffic.
- Get the valuation options in writing before you sign anything.
Start your search with movers in Portland, your origin. Ask each carrier how often it runs the Portland–Seattle corridor and which Seattle deliveries it has handled.
Portland-to-Seattle questions, answered
How long is a moving truck on I-5 between Portland and Seattle?
Plan for 3 to 4 hours under typical conditions, covering roughly 175–180 miles via I-5 North. Traffic through Tacoma and into Seattle can add 30–60 minutes during peak hours, particularly on weekday afternoons and summer weekends. An early morning departure from Portland gets the truck ahead of that traffic.
Does crossing the Columbia River into Washington make this an interstate move?
Because the move crosses a state line (Oregon to Washington), it is classified as an interstate move, regardless of the short distance. That means federal regulations apply, your mover must hold USDOT and MC authority, and pricing is typically based on shipment weight and mileage rather than hourly rates.
What does leaving Oregon's income tax for Washington's sales tax mean for my paycheck?
Potentially a meaningful saving for higher earners. Oregon levies a state income tax of up to 9.9%, while Washington has no state income tax. However, Washington's sales tax (which Oregon doesn't have) will offset some of that advantage depending on your spending habits. Run your own numbers based on your income and lifestyle.
Does the month I move change the quote for Portland to Seattle?
Ask each mover to price the same shipment for more than one date and put the dates in the written estimate. The quote is tied to the date and window you agree to. If your timeline is flexible, comparing a few dates costs nothing.
Do I need to reserve a parking permit for the moving truck in Seattle?
Often, yes. Seattle neighborhoods and apartment buildings commonly require you to reserve a loading zone or obtain a temporary no-parking permit for your moving truck. Contact your new building management or the Seattle Department of Transportation well in advance. Your mover should be familiar with this process; if they're not, that's a flag.
How do I check that a mover is licensed for an Oregon-to-Washington interstate move?
Look up the company's USDOT number on the FMCSA's Safety and Fitness Electronic Records (SAFER) system at safer.fmcsa.dot.gov. An interstate mover will have active USDOT registration and motor carrier authority. If a company can't provide a USDOT number, don't hire them for an interstate move.
