Miami’s Warehouse Market Has A Divide That Tenants Should Watch

Miami-Dade County’s industrial market is showing a widening divide between smaller warehouses and large distribution buildings—a distinction that matters for businesses searching in Doral and near Miami International Airport. Marcus & Millichap’s fourth-quarter 2026 outlook reports vacancy of 10.4% among properties larger than 50,000 square feet, compared with 4.5% in smaller properties.

Those countywide figures help explain why a business seeking a modest warehouse may encounter different conditions than a company shopping for an entire distribution center.

New Construction Has Favored Larger Buildings

According to Marcus & Millichap, Miami-Dade’s inventory of industrial properties larger than 50,000 square feet increased 6.7% since the first quarter of 2024. Inventory of smaller properties increased just 0.1% over the same period.

That uneven expansion has given larger users more space to consider while adding little inventory at the smaller end of the market.

Smaller properties have experienced some softening, too. Marcus & Millichap reports that tenant departures pushed their vacancy rate up more than two percentage points over the past year. Even with that increase, their vacancy remains substantially below the rate for larger buildings.

Smaller Requirements Are Reshaping Leasing

Separate research from Colliers shows that the average industrial lease size across South Florida declined from approximately 75,000 square feet in 2020 to about 46,000 square feet in 2026.

An average lease size does not describe every tenant’s requirements, but the shift underscores the importance of smaller industrial spaces within the broader market.

Colliers also identifies a constraint on future supply: modern small-bay properties can be difficult to develop economically. That limits the addition of new competing space and helps support occupancy and pricing.

Investors have continued buying into that segment. Colliers tracked at least 10 small-bay portfolio transactions across South Florida in 2026, with an average transaction value of approximately $31 million.

What This Means For A Doral Warehouse Search

For businesses looking in Doral, the practical takeaway is to evaluate availability within the size range and property type they actually need.

A higher vacancy rate among large buildings does not automatically translate into more suitable small suites. Building size and available suite size are also different measures: a larger industrial property may accommodate several smaller tenants.

A useful search should compare available square footage alongside loading access, clear height, office buildout, parking and permitted use. Those requirements determine whether an available property offers a workable alternative.

Owners should make similar distinctions when evaluating competing listings. A small warehouse and a large distribution building may serve different tenants, even when both fall within the same industrial submarket.

The regional data points to a market where building size increasingly shapes the choices available. For Doral tenants and owners, understanding that difference provides a more useful starting point than relying on a single countywide vacancy figure.
