“Rising Industrial Vacancy in Salt Lake City — What It Means for Boise Commercial Real Estate”

by | Apr 22, 2026 | Boise, Idaho

Spec Builds, Slower Demand — What Salt Lake’s Logistics Shift Signals for Boise Industrial Real Estate

Industrial real estate doesn’t turn overnight—but when it does shift, it usually starts with supply getting ahead of demand.

That’s exactly what’s unfolding in Salt Lake City right now. And if you’re watching Boise commercial real estate, there are some very real takeaways worth paying attention to.

According to reporting by CoStar News journalist John Gillem (read the original article here: https://product.costar.com/home/news/1377411519), a wave of speculative logistics development is pushing vacancy rates higher—even as construction begins to slow.

But this isn’t just a Utah story. It’s a preview of what could happen in markets like Boise.

What’s Changing: Supply Outpaced the Surge

Salt Lake’s industrial market rode the same wave most Western cities did during the pandemic—rapid tenant expansion, supply chain urgency, and a rush to build.

Now, that momentum is cooling.

Here’s what stands out:

  • Vacancy climbed to 10.1%, up sharply from 2.9% in mid-2022
  • Roughly 36 million square feet has been added since 2020
  • About 20% of that space is still available
  • Of the newest deliveries, over 75% remains unleased
  • Sublease space is easing slightly, now at 17.9% of availability

In short: a lot of buildings delivered at the same time… just as tenant demand slowed.

The Real Pressure Point: New Construction

Not all vacancy is created equal—and that’s the key insight here.

Older industrial buildings in Salt Lake are still relatively tight, with vacancy around 6.8%.

But newer product? That’s where the pressure is building.

  • Properties built this decade are sitting at 19.5% vacancy
  • Large-format buildings (500,000+ SF) are especially exposed
  • Nearly all recent big-box deliveries are still available

This is classic late-cycle behavior: developers built for peak demand, but leasing didn’t keep pace.

Why It Matters for Boise Industrial Real Estate

If you’re active in Boise development or industrial leasing, this should feel familiar.

Boise has seen:

  • Strong industrial demand from logistics and distribution users
  • A growing pipeline of speculative development
  • Increasing interest in larger-format warehouse space

But here’s the reality: Boise is not immune to timing risk.

1. Spec Development Comes With Lease-Up Risk

Developers betting on future demand may face longer lease-up periods—especially for big-box product.

2. Tenant Demand Is Normalizing

The urgency we saw during peak supply chain disruption has cooled. Tenants are still active—but more selective.

3. Big Buildings Need Big Tenants

In both Salt Lake and Boise, a single lease can swing vacancy dramatically in large buildings. Without those anchor users, vacancy lingers.

4. Newer Product May Sit Longer

Just like Salt Lake, Boise could see a gap between delivery and absorption—especially if multiple projects hit the market at once.

Pipeline Watch: The Next Phase

Salt Lake still has 1.5 million square feet under construction, most of it large-format—and about 76% of that space is currently unspoken for.

That signals a market still working through excess supply.

For Boise, the takeaway is simple:
Watch the pipeline closely.

If new deliveries continue without preleasing, vacancy could rise faster than expected—even if overall demand remains healthy.

My Take: This Is a Rebalancing, Not a Red Flag

This isn’t a crash story. It’s a reset.

Markets like Salt Lake—and potentially Boise—are shifting from:

“Build it and they’ll come” → “Build it… and wait.”

For Boise commercial real estate, that creates opportunity:

  • Tenants may gain negotiating leverage
  • Investors can find deals in newer, slower-leasing assets
  • Landlords need to sharpen positioning, pricing, and concessions

The winners in this next cycle won’t just be the ones who built—they’ll be the ones who can lease.

Local Insight: Boise Isn’t There Yet—But It’s Getting Closer

Boise’s industrial market still has strong fundamentals.

But if you’re watching closely, you can see early signs of the same pattern:

  • More speculative construction
  • Slightly longer marketing times
  • Increased competition for large users

Salt Lake is just a few steps ahead in the cycle.

And that’s exactly why it matters.
