Spec Industrial Pushes Outward — What a Washington Project Signals for Boise Industrial Growth
Not all industrial development happens in the obvious places.
Sometimes, the smartest bets show up just outside the spotlight—where land is available, infrastructure is improving, and demand is quietly building.
A recent example out of Washington highlights exactly that trend—and it has real implications for Boise commercial real estate.
According to reporting by Randyl Drummer in CoStar News (read the original article here: https://product.costar.com/home/news/101892148), national developer Panattoni is moving forward with a new industrial park in North Bend, a smaller town about 30 miles east of Seattle.
What’s Changing: Industrial Development Is Moving to “Edge Markets”
The project—called Mount Si Industrial Center—includes roughly 350,000 square feet across three buildings and is expected to break ground immediately, with delivery targeted for mid-2027.
Here’s what stands out:
- Built speculatively (no tenants signed yet)
- Located in an “underserved, emerging” submarket
- Positioned near major anchors like a Nintendo distribution center and outlet retail
- Backed by a $42.6 million construction loan from Fifth Third Bank
This isn’t happening in downtown Seattle—it’s happening in a smaller, outlying community.
And that’s the story.
Even more interesting: this project is moving forward despite weak industrial absorption in the Seattle region, which reportedly ranks among the lowest of major U.S. markets over the past year.
At the same time, about 90% of industrial construction in Seattle is speculative, meaning developers are building without pre-leasing.
That’s a bold signal.
Why It Matters: Developers Are Playing the Long Game
At first glance, building spec space in a soft leasing environment might look risky.
But zoom out, and the strategy becomes clearer:
- Land constraints in core markets are pushing development outward
- Lower costs in secondary areas improve long-term returns
- Logistics networks are expanding beyond urban cores
- Developers are betting on future demand, not current conditions
In other words, this isn’t about today’s vacancy—it’s about where demand is heading over the next 5–10 years.
And that’s exactly how institutional developers like Panattoni operate.
Local Market Impact: Boise Is Following a Similar Path
If you’re watching Boise development and the broader Treasure Valley, this should feel familiar.
We’re seeing the same pattern play out:
1. Industrial Growth Is Expanding Beyond Core Boise
Markets like Nampa, Caldwell, and Kuna are becoming the next wave of industrial development. Just like North Bend sits outside Seattle, these submarkets are positioned to capture overflow demand.
2. Spec Development Is Becoming More Common
More developers in Boise commercial real estate are willing to build without tenants in place—especially for smaller-bay industrial and flex space.
That’s a shift from the more conservative, pre-leased model we saw years ago.
3. Infrastructure + Access Is Driving Site Selection
Projects near highways, distribution nodes, and population growth corridors are winning.
That mirrors what’s happening in North Bend—proximity to existing logistics and retail anchors matters.
Key Takeaways for Boise Investors and Developers
- Emerging submarkets are no longer “secondary”—they’re strategic
- Spec industrial is becoming a normalized risk, not an exception
- Developers are prioritizing positioning over timing
- The next big opportunities may not be in Boise’s core—but just outside it
My Take: Pay Attention to the “Next Ring” of Growth
If you’re focused only on core Boise, you might miss where the real movement is happening.
The smarter play right now?
Start tracking land, zoning, and industrial activity in the next ring of growth markets.
That’s where:
- Pricing still makes sense
- Entitlements are more flexible
- And long-term upside is strongest
What’s happening in a small town outside Seattle today could easily mirror what happens around Boise tomorrow.
And in commercial real estate, those early signals are where the biggest opportunities live.
