Rockville sits in the middle of Montgomery County’s I-270 Corridor, the part of Suburban Maryland best known for life sciences, federal agencies, and dense office parks. Its industrial base is small and old, and that shapes everything a small business will run into when it looks for space here.
The headline numbers look healthy. Vacancy in North Bethesda/Rockville is about half the Suburban Maryland average, according to Cushman & Wakefield. The harder question is whether a business that needs 500 or 1,500 Sq Ft can find a space, a term, and a setup that fits, in a submarket where most listings are built and priced for larger users.
Vacancy and absorption
Cushman & Wakefield tracks about 6.6 million Sq Ft of industrial inventory in North Bethesda/Rockville, roughly half of Montgomery County’s total.
| Q2 2026 measure | North Bethesda/Rockville | Gaithersburg/Germantown | Montgomery County |
|---|---|---|---|
| Inventory | 6,603,181 Sq Ft | 7,329,940 Sq Ft | 13,933,121 Sq Ft |
| Overall vacancy | 5.5% | 9.2% | 7.4% |
| Q2 net absorption | -55,500 Sq Ft | +43,255 Sq Ft | -12,245 Sq Ft |
| YTD net absorption | -136,283 Sq Ft | -43,463 Sq Ft | -179,746 Sq Ft |
| Under construction | 100,854 Sq Ft | 0 Sq Ft | 100,854 Sq Ft |
Suburban Maryland as a whole (53,976,922 Sq Ft) ran 11.0% vacancy in Q2 2026, with 63,275 Sq Ft of positive year-to-date net absorption and 538,818 Sq Ft under construction.
Vacancy in North Bethesda/Rockville rose from 3.4% in Q1 2026 to 5.5% in Q2, as the submarket gave back space in both quarters. Even so, it remained one of the tighter industrial submarkets in Suburban Maryland, where Prince George’s County ran 10.0% and Frederick County 27.1% after a wave of new deliveries.
NAI KLNB’s Q3 2026 figures, which define the I-270 Corridor more broadly, point the same way. The corridor’s 13.96 million Sq Ft of industrial space was 5.4% vacant, with 30,671 Sq Ft of negative net absorption in the quarter but 124,192 Sq Ft of positive absorption over the trailing 12 months. I-270 flex space was looser, at 8.1% vacancy across 11.17 million Sq Ft.
A fixed, aging small-bay supply
Montgomery Planning’s 2021 review of county industrial land, based on CoStar data, explains why small space stays scarce. The county had 655 industrial properties totaling about 15.5 million Sq Ft. Most of it (87%) was service or warehouse space, 63% of buildings were smaller than 20,000 Sq Ft, and only 13 buildings were larger than 100,000 Sq Ft. Development peaked in the 1980s, and the report found no undeveloped areas in the county that permit new industrial uses.
More than half of the county’s industrial land sits in three clusters: the Montgomery County Airpark area, Gaithersburg, and Rockville/North Rockville. When an older building in one of those clusters is redeveloped for housing, labs, or retail, that small-bay space rarely comes back. The I-270 Corridor industrial areas guide maps where the remaining stock is.
New supply is thin. Cushman & Wakefield counted a single 100,854 Sq Ft project under construction in North Bethesda/Rockville in Q2 2026, at 15400 Calhoun Dr. Across Suburban Maryland, Frederick County accounted for 88% of new supply.
Market asking rents
Broker rent figures are weighted net asking rents for larger industrial leases. They exclude operating expenses such as taxes, insurance, and common-area charges, and they do not describe small-unit pricing.
| Source and period | Area | Product | Asking rent (per Sq Ft per year) |
|---|---|---|---|
| Cushman & Wakefield, Q2 2026 | North Bethesda/Rockville | Office service/flex | $17.10 |
| Cushman & Wakefield, Q2 2026 | North Bethesda/Rockville | Warehouse/distribution | $17.00 |
| Cushman & Wakefield, Q2 2026 | Gaithersburg/Germantown | Office service/flex | $15.95 |
| NAI KLNB, Q3 2026 | I-270 Corridor | Industrial | $16.56 |
| NAI KLNB, Q3 2026 | I-270 Corridor | Flex | $24.55 |
| CBRE, Q3 2026 | Suburban Maryland | Industrial | $14.53 |
CBRE reported Suburban Maryland asking rents up 3.6% year over year in Q3 2026, while Cushman & Wakefield’s Q2 figures showed the regional average down $0.85 per Sq Ft from a year earlier. The two firms define the market differently, so treat the direction as mixed and the Rockville premium over the regional average as the steadier signal.

Who needs space near Rockville
Rockville Economic Development, Inc. (REDI) describes the city as a life-science and biotech hub, close to the National Institutes of Health and the U.S. Food and Drug Administration. Much of the demand for small industrial space comes from the businesses around that economy: lab suppliers, equipment service firms, specialty contractors, event and media companies, and local distributors serving the dense neighborhoods of North Bethesda, Potomac, and Gaithersburg.
NAI KLNB’s Q3 2026 commentary notes that investor demand is stronger for smaller-bay infill product, and that flex users want loading, power, parking, and office space in one place. That is the same mix many small operators struggle to find in a single listing. The flex space vs. small warehouse guide compares the two.
Access and logistics
2800 Tower Oaks Blvd sits beside the I-270 Montrose Road interchange in Rockville’s Tower Oaks area. I-270 connects north toward Gaithersburg and Frederick and south to the Capital Beltway (I-495). Rockville Pike (MD 355) runs to the east, and Twinbrook and Rockville stations on the Metro Red Line are each about 1.7 miles away in a straight line, with MARC and Amtrak service at Rockville station.
Choosing small warehouse space in Rockville
- Check whether your address is inside Rockville city limits or in unincorporated Montgomery County. Permits and occupancy approvals come from different offices. The Rockville permits guide covers both.
- Compare total monthly cost, not only the asking rate, and weigh multi-year terms against a 6- or 12-month agreement.
- If you are storing stock in self-storage today, read business storage vs. self-storage in Rockville before you outgrow it.
- Trades that need staging space near I-270 can start with the contractor storage guide.

Methodology
This report compiles published third-party data. Cushman & Wakefield and NAI KLNB define submarkets differently, so their figures are shown side by side rather than combined. Rents are weighted net asking rents per Sq Ft per year as each firm reports them. Montgomery Planning’s building counts come from CoStar data published in 2021. No WareSpace leasing data is included.
