- Industrial Outdoor Storage (IOS) is experiencing a sharp rise in demand and rents, with values outperforming even the bulk warehouse sector.
- AI and data center development are fueling the need for staging grounds, equipment storage, and logistical support — roles IOS properties are uniquely positioned to fill.
- $300B worth of IOS real estate is institutionally investable, with big players like Blackstone, J.P. Morgan, and Blue Owl Capital now entering the space.
- Despite promising fundamentals, zoning constraints and economic headwinds pose risks for future expansion.
The Big Picture
A quietly booming corner of commercial real estate is attracting big-time investment: Industrial Outdoor Storage, reports CNBC. These are paved or gravel lots used for storing everything from shipping containers to heavy machinery. They’ve become critical infrastructure supporting the country’s data center and logistics buildout.
Now, with AI and quantum computing fueling new demand for data centers, IOS has emerged as a vital and increasingly scarce asset class.
Not Just Dirt Lots Anymore
Traditionally the domain of local business owners, IOS is now undergoing institutionalization. IOS is defined by land parcels where structures occupy less than 25% of the site. It plays a support role in supply chains, construction, and infrastructure — especially in urban-adjacent industrial zones.
Sites near ports, highways, and major distribution hubs are seeing increased demand. They are increasingly used as staging grounds for AI data centers, which require temporary space for large generators, backup systems, and delivery trucks.

Big investors are buying in. In August, Zenith IOS launched a $700M joint venture with J.P. Morgan, targeting a national IOS portfolio valued at over $1.5B.
Other notable deals include:
- Blackstone’s $189M loan commitment to Alterra IOS for 49 sites
- $231M loan to Jadian Capital for a 43-site portfolio
- Blue Owl Capital’s first IOS financing — a $150M facility backing Alterra’s acquisitions
Alterra IOS, a leading operator in the space, has already acquired more than 400 sites nationwide.
Performance Metrics
According to Newmark, IOS rent growth has increased 123% since 2020, with top-performing markets including Phoenix, Memphis, and Atlanta. Vacancy rates are roughly half that of bulk warehouses, and in some cases, rents are comparable when measured per acre.
By comparison, IOS now outpaces better-known niche assets like marinas, RV parks, and self-storage in total market size and institutional interest.
A Scarce Asset With Strong Fundamentals
Despite covering 1.4M acres in the US, well-zoned and well-located IOS parcels are hard to come by. That scarcity is driven in part by zoning challenges — municipalities are increasingly reluctant to approve IOS sites, viewing them as low-tax, low-employment uses.
“The No. 1 biggest risk is zoning,” said Leo Addimando, CEO of Alterra IOS. “No one’s giving zoning variances for IOS real estate.”
What’s Next
While macroeconomic factors like high interest rates and tariffs loom large, the sector’s fundamentals remain solid. Institutional investors are betting on continued growth tied to AI, logistics, and e-commerce — all of which rely heavily on outdoor storage infrastructure.
With $300B in addressable IOS real estate still owned by small businesses, expect further consolidation — and further investor interest — in this once-overlooked asset class.
