Meta adds two more buildings at Kuna campus on 40-acre expansion

Meta is expanding again in Kuna. BoiseDev reports the company is building two additional rapid deployment structures at its campus, and city records show the work is tied to a site plan amendment that added 40 acres north of the existing campus.

That’s worth paying attention to because it shows the Kuna campus didn’t stop changing once the main facility opened. For people tracking Kuna growth, this is another example of a big employer project continuing to add pieces after the headline launch.

What Meta is building

According to BoiseDev, Meta’s Brad Davis said the new buildings are rapid deployment structures made with an aluminum substructure covered by weather-resistant fabric. He told BoiseDev each one takes about eight months to set up, and he estimated both would be finished by the end of 2026.

BoiseDev also reported that:

• There are two new structures under construction
• They add a small additional percentage of capacity
• Meta did not disclose the exact amount
• The Kuna data center campus cost $1.2 billion

I think the important thing here is not to overread the size of the expansion. Meta said it adds some capacity, but not how much. So the confirmed news is the physical expansion and the timeline, not a specific jump in output.

Where the expansion sits

City of Kuna materials for Case No. 25-24-DR describe the request as a design review for a Kuna Data Center site plan amendment. The city agenda says the application added 40 acres north of the existing campus.

The records list the site as:

• 14375 S Cole Rd., Kuna
• Parcel No. S1531222400

Kuna Rural Fire District comments tied to the same case reference a Meta site expansion and two new structures at:

• 601 Kuna Mora Road, Kuna, ID

Those addresses and references all point to the north side of the existing campus in the same broader project area.

What happens next

There’s still more review ahead even with construction underway. Kuna Rural Fire District comments say final conditions for each structure will be set during later building-permit and fire-code review.

The same comments say the available firefighting water supply has to be included with the complete building-permit application.

BoiseDev also noted that Meta’s campus water rights allow up to 3.7 million gallons per day, and Davis said the new structures’ water use remains within those existing water rights. BoiseDev separately reported that these rapid deployment structures use evaporative cooling, while the main data center operates as a closed-loop system.

So if you’re watching this story, the next meaningful checkpoints are the permit reviews and whether the end-of-2026 construction target holds.

My take

For Kuna homeowners and buyers, this is one of those stories that matters because it confirms momentum, not because it changes everything overnight. The campus already opened last month, according to BoiseDev. What this update shows is that nearby growth pressure and infrastructure questions don’t end when the first phase is done.

If you’re making housing decisions in Kuna, I’d keep a few things in mind:

• This year: the visible change is ongoing construction activity.
• Longer term: large employment centers tend to keep surrounding land in play for more development.
• If you live nearby: city case files and permit reviews are worth following if you want facts instead of rumors.

I’d also keep the tradeoffs in view. Continued investment can bring confidence to an area, but it also means more phasing, more service demands, and more questions about roads, utilities, and emergency coverage. That’s usually the real story once the first building is already open.
