How our United States self-storagefigures are sourced.
Every United States self-storage figure on Real Assets links to the page that published it. Counts are sites tracked, not a census. As of 21 October 2026: 1,515 sites, 1,496 with a source link.
What we record
Real Assets reads company pages, filings, reports, news and listings, and records what they state about United States self-storage: where a site is, who runs it, what status it has and, where a source gives one, a figure such as size. As of 21 October 2026 that is 1,515 sites, 1,515 of them placed on a map, and 4,931 sourced figures.
What a source line means
Every figure in the workspace carries a source line: the publisher, the link to the page, the date we read it and, for a report, the page and the exact words it prints. A source line says where a figure was read, not that we checked the figure against anything else. 1,496 of the 1,515 sites here carry a source link; the others are listed as recorded and their figures are not shown as sourced. Publishers behind this market's data include Public Storage, Merit Hill Capital, Inside Self-Storage, Compass Self Storage.
Counts are sites tracked, not a census
A count on these pages is the number of sites Real Assets has recorded, not the number that exist, so it can be lower than a figure published by a body that counts the whole market. Rankings are by sites tracked unless a page says otherwise, so they can differ from a ranking by capacity or area.
Operating and planned
Operating means a site that is open. Planned means a site that is not open yet: announced, planned or under construction. The two are shown side by side and are never added together, because a planned site may change, move or not be built.
Rates and benchmarks are not on these pages yet
Market rates such as vacancy, rent, yield and cap rate are not published on the public pages. The workspace holds some of them from published reports, but a person has not reviewed them yet, so we do not present them as checked. Where publishers give different figures for the same market, a benchmark will show each publisher with its period and definition side by side and will not blend them into one number.
Updates and corrections
Public figures are updated as sites, sources and deals are added; this page's figures are as of 21 October 2026. To report a mistake or ask where a figure comes from, write to hello@analystai.ai.
