US self-storage market, mapped
Largest Self-Storage Chains in the US: 52,000 Facilities, Top 5 Hold 23%
By US facility count, the 5 largest self-storage REITs operate around 12,000 of 52,000 facilities. Extra Space Storage leads at roughly 3,700 facilities post-Life Storage. The remaining 77% is independents and single-asset LLCs, and those are the active acquisition targets.
The market, in three numbers
The most REIT-consolidated real-estate vertical in America.
share held by the top 5 REITs
Public Storage, Extra Space, U-Haul, CubeSmart, and National Storage Affiliates together operate around 12,000 of the 52,000 US facilities. A decade ago that figure was closer to 14 percent.
independents and single-asset LLCs
Around 40,000 US self-storage facilities are mom-and-pop operators, regional banners under 100 sites, or single-purpose LLCs holding one asset. These are the active acquisition targets for the REITs.

Methodology
Why we anchor on 52,000 and not the 65,000 you sometimes see.
There are two reasonable answers to "how many self-storage facilities are in the US," and they sit about 13,000 apart. The Self Storage Almanac says 52,000 to 60,000. A wider commercial-real-estate classifier returns closer to 65,000. The gap is real and it is mostly definitional.
How the 52,000 figure is built
- Start with the Self Storage Almanac universe. The Almanac is the industry-canonical reference, published annually by Mini-Storage Messenger. Its 2024 figure puts active US self-storage facilities at 52,000 on the conservative end, 60,000 on the wide end. We anchor on 52,000 because it is the figure REIT investor decks, Cushman Wakefield self-storage reports, and the trade press cite as the floor.
- Cross-check against the facility-level map. Mapping every active US storage-classified location returns close to 65,000 records. That higher count picks up mixed-use commercial properties (a U-Haul truck-rental site with a small storage block, a moving company with a 50-unit rental yard) and co-located facilities the Almanac collapses into one line. Both views are correct; they answer different questions.
- Resolve each facility to a real operating business. A single-asset LLC under a regional banner is a different buyer than the franchise corporate office. We surface both, and we keep them separate.
- Roll up the chains, carefully. Extra Space, Public Storage, and CubeSmart are clean rollups. Storage Sense, operated as a franchise network, is harder; we report the network total separately from the individual franchisee LLC counts. The caveat is on the table, not hidden in a footnote.
- Find the owner. Around 77 percent of US self-storage facilities are independents or single-asset LLCs. Most of those owners do not have a polished LinkedIn presence. We find them by name, with a verified email and a direct dial, the same way we find owners across every long-tail vertical.
- Drop the dead pins. Closures, demolitions, sites rebranded after a REIT acquisition. Annual industry reports keep them on for twelve months. We do not.
- Refresh on a rolling schedule. June 2026 is the snapshot quoted on this page. Counts move every month because the REITs are buying independents and the franchise networks (Storage Sense, StorageMart, StorQuest) are net-adding sites quarter over quarter.
Want the source breakdown for a specific state, metro, or facility type (climate-controlled, drive-up, RV and boat)? Ask. We do not hide the working.
By state
Where the US self-storage facilities actually are.
Texas leads at 7,237 facilities, more than 50 percent ahead of California in second place. The Sun Belt does the heavy lifting because cheap land plus relocation churn makes new builds pencil where coastal infill never does. The top 15 states hold roughly 75 percent of US self-storage facilities mapped against the Almanac universe.
| # | State | Facilities | Share of US |
|---|---|---|---|
| 1 | Texas | 7,237 | 13.9% |
| 2 | California | 4,767 | 9.2% |
| 3 | Florida | 3,992 | 7.7% |
| 4 | North Carolina | 2,402 | 4.6% |
| 5 | Georgia | 2,221 | 4.3% |
| 6 | Ohio | 2,188 | 4.2% |
| 7 | Michigan | 2,170 | 4.2% |
| 8 | Illinois | 2,078 | 4.0% |
| 9 | New York | 2,072 | 4.0% |
| 10 | Wisconsin | 2,008 | 3.9% |
| 11 | Pennsylvania | 1,973 | 3.8% |
| 12 | Tennessee | 1,876 | 3.6% |

The top ten chains
Largest US self-storage chains by facility count.
Five REITs sit on top of every other operator in this market by a wide margin. The combined top 5 run about 12,000 facilities. The next five chains together add another roughly 2,000 facilities, and there is a long, choppy drop from there into the independents.
| # | Chain | US facilities | Parent / note |
|---|---|---|---|
| 1 | Extra Space Storage | ~3,700 | NYSE:EXR. Figure includes the Life Storage acquisition (closed July 2023, formerly NYSE:LSI). Combined entity runs the wholly-owned book plus a large third-party management book for outside owners. |
| 2 | Public Storage | 3,334 | NYSE:PSA. Largest self-storage operator by rentable square footage, even as Extra Space leads on raw facility count. Acquired Prime Storage in a roughly 2.2 billion dollar transaction announced in 2024 (see row 8). |
| 3 | U-Haul | 1,691 | AMERCO subsidiary (NYSE:UHAL). Self-storage is the second pillar of the business behind truck rental; many U-Haul locations co-locate storage with the rental yard. |
| 4 | CubeSmart | 1,466 | NYSE:CUBE. Pennsylvania-headquartered REIT. Includes both wholly-owned facilities and a sizable third-party management book. |
| 5 | National Storage Affiliates | 1,075 | NYSE:NSA. Operates through a Participating Regional Operator model; regional operators retain branding (Northwest Self Storage, SecurCare, Move It, others) under the NSA umbrella. |
| 6 | Storage Rentals of America | 672 | Privately held (SROA). Florida-headquartered, aggressive acquirer of independent operators across the Southeast and Mid-Atlantic. |
| 7 | Storage Sense | ~318 | Franchise network operated by Storage Sense LLC. Count is the floor for the network total; individual franchisee LLCs file under their own legal entity. Actual storefront count likely higher. |
| 8 | Prime Storage | 307 | Privately held by Prime Group. Acquired by Public Storage in 2024 in a roughly 2.2 billion dollar transaction; integration ongoing through 2026. |
| 9 | Simply Self Storage | ~290 | Blackstone-owned. Acquired from Brookfield in 2023 for around 1.2 billion dollars. Blackstone Real Estate Income Trust holds the asset. |
| 10 | StorQuest Self Storage | 247 | William Warren Group banner. Privately held, concentrated in California and the Mountain West. |
| * | Top 5 REITs combined | ~11,266 | Public Storage plus Extra Space plus U-Haul plus CubeSmart plus NSA. Roughly 23 percent of the 52,000 Self Storage Almanac universe, up from around 14 percent a decade ago. |
| * | Acquisitions in 2023 to 2024 | 3+ | Extra Space and Life Storage closed July 2023. Blackstone and Simply Self Storage closed 2023. Public Storage and Prime Storage announced 2024. The top-5 share creeps up every year. |
As of June 2026, US open facilities. Storage Sense and other franchise networks may under-count where individual franchisee LLCs file under their own legal entity.
Our take
Self-storage is quietly the most REIT-consolidated real-estate vertical in America.
We believe
Top 5 REITs run 23% of US facilities, up from 14% a decade ago. The other 77% is the acquisition pipeline.
Self-storage is the most quietly REIT-consolidated real-estate vertical in America. The top 5 (Public Storage, Extra Space, U-Haul, CubeSmart, NSA) together operate around 12,000 of the 52,000 US facilities, 23 percent concentration that has grown from 14 percent a decade ago. The remaining 77 percent is mom-and-pop or single-asset LLCs that are the active acquisition targets for the same five REITs. If you sell into self-storage operations (access control, payment, lead-gen), the top 5 are platform contracts; the 35,000 independents are where new logos come from.
That gap matters when you pick your motion. Build pipeline around five enterprise logos and you are fighting every other vendor for the same five procurement seats. Know the long-tail map and you run the same conversation 35,000 times, with a different LLC on the door, and ride the ones the REITs eventually roll up.
Who buys this data
B2B vendors selling into 52,000 facilities.
This page is for the teams selling into self-storage operators, not the tenants storing the boxes. If you ship one of the categories below, you need the facility-level map plus the owner name, not a REIT-only roll-up that hides 35,000 of your 40,000 buyers.
Facility management software
storEDGE, SiteLink, Storable, Easy Storage Solutions, Sentinel, and the next wave of cloud-based PMS tools selling the upgrade off a legacy desktop scheduler.
Access control and surveillance
OpenTech Alliance, PTI Security, Janus International, and the smart-lock and IP-camera vendors retrofitting older facilities for keypad and mobile entry.
Tenant payments and billing
ACH, card, and recurring billing platforms wired to the PMS. The independents still on monthly invoices are the upgrade target; the REITs already run integrated billing.
Acquirers, lenders, and brokers
REIT corp-dev teams, private storage roll-up sponsors, SBA and bridge lenders, and the brokerage layer (Marcus Millichap, Cushman Wakefield) writing the BOVs. The owner contact is the asset.
Marketing, listings, and lead-gen
SpareFoot, StorageCafe, listing aggregators, Google Local Service Ads agencies, and the SEO shops selling local-search dominance to operators with one to twenty sites.
Construction, doors, and unit systems
Janus International, Trac-Rite, Mako Steel, and the GCs building new boutique facilities and converting old retail boxes into climate-controlled storage. The owner signs the contract.
Tenant protection and operator coverage
SBOA, Bader Company, MiniCo, and the captive-insurance providers running tenant protection programs that the facility owner administers and earns margin on.
Adjacent universes built the same way: the market insights index, the broader by-industry email lists, the sister largest US pest control companies map, and the largest HVAC companies map for the trades family.
Plain-spoken
When the self-storage dataset is the wrong fit.
Do not buy this if any of the following are true.
You only sell into the top 5 REITs. If your motion is one annual platform contract with Public Storage or Extra Space, you do not need a facility-level map of 52,000 records. You need five relationships and a procurement contact list. Save your budget.
You sell to storage tenants directly. Movers, packing supplies, renter insurance to the household. That is consumer data, not facility owner contacts. Different list, different vendor.
Your sales motion only fires above $250k ACV. The 35,000 single-asset LLCs and mom-and-pop operators will not fit your unit economics. A single-site owner with 350 units rarely writes a six-figure annual check on day one. Call us when an enterprise-only motion stalls and you need a mid-market overlay.
You need real-time auction inventory. Storage lien auction inventory moves daily and the aggregators (StorageTreasures, Lockerfox) publish that better than we do. We refresh monthly, which is the right cadence for prospecting and the wrong cadence for tracking auction listings.
The honest version
Why most self-storage vendor data is wrong.
If you Google "largest self-storage chains in the US," the top result is usually the Inside Self Storage Top Operators list or the SpareFoot top-operators page. Both are good. Inside Self Storage ranks by rentable square footage and is the canonical industry reference, refreshed annually. SpareFoot ranks by facility count and serves up listings to consumers. Statista resells the SpareFoot view to enterprise buyers at a higher price. None of them have the buyer.
The Inside Self Storage view flatters the public REITs, correctly, because they own the most rentable space. By square footage, Public Storage leads by a wide margin. By facility count, Extra Space leads after the Life Storage close. By independent storefront, the answer is none of the above: the 35,000 single-asset LLCs and mom-and-pop operators together hold roughly 77 percent of US self-storage facilities. SpareFoot sees the listing but not the owner. Statista sees the brand but not the LLC. The facility-level view sees both.
The second problem is that enterprise B2B databases roll up by parent and lose the buyer. They show "Extra Space" as one customer at the Salt Lake City HQ and the 3,700 facilities collapse into a single row. The actual buyer for most self-storage vendor categories is a district manager, a regional operator, or an independent owner who never reports up to corporate procurement. Inside Self Storage sees the operator but not the procurement seat. Generalist databases see the parent but not the facility. The facility-level view sees both.
This is the gap Orbital sits in. We map the universe of US small and mid-market businesses, classify each facility into its market, find the owner or decision-maker for that facility, and ship a verified contact before the conversation starts. That works for self-storage the same way it works for HVAC, dental, and pest control. What is specific to self-storage is the layer on top: chain affiliation, parent REIT, facility type (climate-controlled, drive-up, RV and boat, business), and the management relationship (wholly-owned vs third-party managed) when the operator publishes it. We are the facility-count complement to Inside Self Storage, not a replacement. Use both. Inside Self Storage tells you who owns the most square feet; this page tells you who signs the contract at facility #2,847. Inside Self Storage Top Operators is the square-footage lens; this is the facility lens. IBISWorld's Storage and Warehouse Leasing report is the market-size lens, refreshed every twelve to eighteen months.
Questions
Before you ask sales about self-storage data.
How many self-storage facilities are there in the US?
There are roughly 52,000 active US self-storage facilities as of the 2024 Self Storage Almanac, the canonical industry reference published by Mini-Storage Messenger. Orbital's facility-level map shows close to 65,000 storage-classified records, but that figure includes mixed-use commercial properties and co-located facilities that the Almanac counts as one. We anchor on the conservative 52,000 number on this page.
How is Orbital's count different from the Self Storage Almanac?
The Self Storage Almanac is the industry-canonical universe figure, refreshed annually, and 52,000 facilities is its conservative estimate for 2024. Orbital's classifier returns a wider count because we include some mixed-use commercial properties and pick up co-located facilities that the Almanac collapses into a single line. Both views are useful. Almanac for the headline number; Orbital for the facility-level address, the brand affiliation, and the named owner for each independent.
Who is the largest self-storage company in the US?
Extra Space Storage is the largest US self-storage operator by facility count, at roughly 3,700 facilities once the Life Storage acquisition (closed July 2023) is rolled in. Public Storage sits second at 3,334 US facilities. U-Haul is third with 1,691 self-storage facilities, in addition to its truck-rental footprint. CubeSmart and National Storage Affiliates round out the top five.
How concentrated is the self-storage market?
More than most local-service verticals, less than the press coverage suggests. The top 5 REITs (Public Storage, Extra Space, U-Haul, CubeSmart, NSA) operate roughly 12,000 of the 52,000 US facilities, around 23 percent of the market by facility count. A decade ago that figure was closer to 14 percent. The remaining 77 percent is independents and single-asset LLCs, and the same five REITs are the active acquirers of that long tail.
Can I filter by state, metro, or facility type?
Yes. The dataset is filterable by state, metro, ZIP, chain affiliation, parent REIT, and facility type (climate-controlled, drive-up, RV and boat, business storage). Texas, California, and Florida together hold roughly 24 percent of US self-storage facilities, so most vendors start with those three plus their named target metros. Tell us the cut you want when you request the sample.
How is this list refreshed?
Orbital refreshes the facility graph against the universe of US small and mid-market businesses on a rolling monthly schedule. The Self Storage Almanac publishes annually and lags by 6 to 12 months at any given point. SpareFoot and the REIT 10-Ks publish quarterly but only at the brand level, not the facility level. Counts on this page move when facilities open, close, or change hands, including the steady drip of REIT acquisitions of independents.
When is this dataset the wrong fit?
Three cases. First, if you only sell into the top five REITs, you need five relationships and a procurement contact list, not 52,000 records. Second, if you sell to storage tenants directly (movers, packing supplies, insurance to renters), you want consumer data, not facility owner contacts. Third, if your sales motion only fires above 250,000 dollars in annual contract value, the 35,000 single-asset LLCs and mom-and-pop operators will not fit your unit economics. Save your budget.
Does the count include facilities owned by REITs but managed by third parties?
Yes, and we label both layers. The Extra Space figure includes facilities owned by Extra Space, facilities owned by Life Storage that Extra Space now manages, and the third-party management book that Extra Space runs for outside owners. The procurement decision lives in different places for each of those slices, so we tag the relationship and ship both views. If you want the wholly-owned count only, ask us for that cut.
