Why small-bay supply isn't coming back.

The most reliable edge in real estate is structural scarcity, and small-bay industrial flex has it in a way few asset classes do.

Start with what's being built. Industrial construction over the last cycle has overwhelmingly meant big-box bulk: million-square-foot distribution centers for national tenants near major freight corridors. That's where the institutional capital went, and it's where developers can pencil a deal. What almost no one is building is the 1,500–10,000 SF suite — the small-bay, multi-tenant flex product that local contractors, service businesses, e-commerce sellers, and light manufacturers actually need. Less than 2% of new industrial supply is small-bay.

The reason is economics, not demand. Rising construction, land, and entitlement costs make small-bay product difficult to deliver at a price that works, especially in supply-constrained submarkets. When replacement cost sits well above the price of standing assets, the existing buildings are protected by a moat: a new competitor literally cannot build the same thing for what you paid. Meanwhile the standing inventory is aging — the average industrial building in the United States is over 40 years old — which steadily widens the gap between what tenants want and what exists.

Demand, by contrast, is structural and growing. Three tailwinds reinforce each other: the reshoring of light manufacturing, the continued build-out of last-mile logistics, and the steady formation of small businesses. In a market like Austin — where more than $30 billion of manufacturing and digital-infrastructure investment is underway, from semiconductor fabs to hyperscale data centers, alongside some of the fastest population growth in the country — that demand lands on a submarket with very little modern small-bay product to absorb it.

The result is a quiet but durable setup: national vacancy around 3%, facility costs that have stayed in a tight 3–6% band, and industrial rents that have grown more than 40% cumulatively over two years, with projections of roughly 6% annual growth ahead. For a disciplined buyer and developer, scarcity you can underwrite is worth more than a story you have to believe. Small-bay supply isn't coming back at scale — and that's precisely the point.
