Where the big space is

Every available U.S. industrial building of 250,000 SF and larger, split into existing, under construction and planned (proposed, not yet started). Large marks are 1M+ SF buildings; orange marks heavy power (4,000+ amps) on existing and under-construction buildings. Each market label counts its 1M+ SF buildings by stage (UC = under construction).

Another 21 sit outside the major metros, mostly rural distribution and manufacturing plants.

The headline: There are 143 existing buildings of a million square feet or more with space on the market today, and 66 of them are completely available. Only 7 buildings of 1M+ SF are under construction nationwide; the other 166 in the pipeline are planned and not yet started. The Inland Empire shows the gap best: 60.2M SF existing available, 7.6M SF under construction and 129.5M SF planned, including 50 planned 1M+ SF buildings against 11 existing.

Top markets

The six big-box leaders

Markets group the cities in each metro (for example, Inland Empire includes Ontario, Fontana, Moreno Valley, Perris and the High Desert; NY/NJ includes Northern and Central New Jersey, New York City and Long Island). Asking rent is the median quoted rate (number of buildings quoting); — means fewer than 3 quotes.

Older sale offerings are mostly legacy Midwest and Northeast plants, which pulls the pre-1980 price down. Most landlords of new Class A big-box space don’t publish rates, so new-product rent samples are thin. Est. cap rate on 29 buildings with a figure: median 6.1%.

What it means

Owners

Big buildings take time: the median 250K+ SF listing has been on the market 413 days. Real near-term competition is the 27.5M SF under construction; the 483.8M SF planned pipeline, mostly 40′ clear, starts only when tenants commit, so older 32′ product needs sharp pricing or a power and yard story.

Users

With 143 existing 1M+ SF options and 514 heavy-power buildings, large users have real choice. Quoted rents run about $6.00/SF/yr for pre-1980 space and $8.04 for 2015+ product. Power narrows the list fast: only 83 of the 1M+ SF buildings report 4,000A or more.

Investors

The six top markets hold 32% of available big-box space (442.2M SF). The rising hubs offer 1M+ SF product at lower rents. The few new big-box buildings offered for sale with a price ask a median $140/SF; older plants ask far less, which is where owner-user and value-add basis sits.

Listings as of 9/28/2026: U.S. industrial and flex buildings of 250,000 SF and larger offered for sale or lease, counted once per building (lease, sale and multiple-suite listings combined). Office, retail, land-only and demolished records excluded. Under construction and planned (proposed) follow the listing’s building status. Available SF is the building’s total listed availability. 1M+ SF counts single buildings of 1–4M SF and exclude portfolios and multi-building campuses. Markets follow REIS market definitions; unassigned buildings were placed in the nearest market within 55 miles. Rents are asking, not effective; mostly NNN. Sale prices are asking prices on whole-building offerings. Power figures are as reported in listings, not verified; MVA estimates assume 480V three-phase. No closed-sale data in this edition.
