Self Storage Statistics: Market Size, Rates and Demand Data

Who Uses Self Storage

This is the most frequently mangled statistic in the industry, so it is worth taking slowly.

You will see three different figures quoted, often in the same article:

The 33% and 13.4% figures are not in conflict, because one counts individuals with any usage and the other counts households with a current active rental. A household of four in which one person rents a unit registers once in the household figure and potentially several times in loose readings of the individual figure. Articles that present "one in three Americans rents a storage unit" as a current-penetration statistic are overstating the market by roughly a factor of two and a half.

The trend is unambiguous and more important than the level. The Self Storage Association's recurring study, cited in the PwC and ULI Emerging Trends 2026 report, found household penetration rose from 11.1% in 2022 to 13.4% in 2024, the largest jump between any two survey periods in the study's history. Over that same span there was estimated net absorption of more than 150 million square feet. Placer.ai's reading, that 12.6% of households used storage in 2023 against below 10% before the pandemic, tells the same directional story.

Behaviour is shifting alongside penetration. SpareFoot reports average length of stay reached 18.5 months, up 2.4% year over year. The PwC and ULI report found roughly 60% of surveyed users expected to stay longer than one year, a new high, and notes renters gravitating toward both longer leases and larger units.

What this means for an operator. Rising penetration and lengthening stays mean the tenant you win today is worth more than the equivalent tenant was three years ago, which changes the maths on acquisition cost. If average stay is 18.5 months and your average rate is $120, a tenant is worth roughly $2,200 in gross revenue. Judged against that, the $12.39 average cost per click in our search data looks very different than it does judged against one month's rent.

Search Demand: Where Renters Are Actually Looking

Supply, pricing and occupancy statistics describe the industry's physical and financial state. None of them tell you how many people in your city are looking for storage this month. That is what search demand measures, and it is the dataset StorIQ built because it did not exist in free, city-level form.

Across 2,459 US cities in June 2026, the Demand Index recorded 1,199,890 monthly searches for self storage, at an average cost per click of $12.39. Three additional storage types are tracked separately:

The cost per click spread is the most commercially useful part of this table. Climate-controlled clicks cost $14.00 against $5.84 for boat storage, a difference of nearly 2.4 times. Operators are bidding aggressively for conditioned-space renters and comparatively little for vehicle storage, which is a competitive gap worth knowing about if you have RV or boat capacity.

Regional demand looks quite different once you normalize for how many cities each region contains. Raw regional totals mostly reflect city counts, so the figures below are searches per month per tracked city:

Two patterns in that table are worth pausing on, because they line up with what you would expect from the physical world and therefore act as a sanity check on the data. Climate-controlled demand is nearly three times more intense in the South than in the West, which is what humidity does to storage requirements. RV storage demand is more than twice as intense in the West as in the South, tracking recreational vehicle ownership and the availability of land to park them on.

At the market level, demand and cost diverge sharply even between similar-sized cities. Chicago, Seattle, Las Vegas and Portland all recorded 6,600 monthly self storage searches in June 2026, but cost per click ranged from $14.25 in Portland to $23.88 in Chicago. Same demand volume, a 68% difference in what it costs to buy a click.

What this means for an operator. Search volume is the closest free proxy for move-in demand in your specific market, and cost per click is a live read on how hard your competitors are fighting for it. High volume with low cost per click is the most attractive combination available; high cost per click against flat volume means you are paying more for the same renters and organic visibility becomes the better investment. You can check your own city, and compare it against the storage type you actually offer, in the Self-Storage Demand Index.

Industry Consolidation and the Largest Operators

The top five firms control 37.6% of rentable space, according to SpareFoot, with other large and mid-size operators, each running more than 500,000 square feet, holding a further 22.2%. That leaves roughly 40% of the industry with smaller operators.

By facility count, using Self Storage Almanac 2024 data:

Extra Space took the top position by acquiring Life Storage in April 2023 for approximately $12.7 billion, displacing Public Storage, which had led the industry by facility count for decades.

By 2023 annual revenue: Public Storage $3.4 billion, Extra Space Storage $2.56 billion, CubeSmart $1.05 billion, National Storage Affiliates Trust $858 million, and U-Haul Holding Company $744 million from self storage operations specifically.

What this means for an operator. The consolidated 37.6% is not the number to worry about. The number to worry about is how many REIT-managed facilities sit inside your service radius, because those are the operators with dedicated marketing teams, brand recognition and the occupancy advantage described earlier. Consolidation is a local competitive question dressed up as a national statistic.

Investment and Valuation Statistics

For operators thinking about buying, selling or refinancing, Cushman & Wakefield's H1 2025 Valuation Index provides the clearest published picture. It aggregates data from approximately 520 properties with a combined value of roughly $5.0 billion.

Transaction volume reached nearly $2.85 billion in the first half of 2025, less than one percent above the first half of 2023. That places current activity in line with pre-2020 norms. For scale, the 2020 to 2022 period saw nearly $50 billion in transaction volume, exceeding the $35 billion transacted across the seven years from 2013 to 2020 combined.

Valuations peaked at $174.00 per square foot in Q1 2023 and then declined for six consecutive quarters to an average of $159.00 per square foot in Q2 2025, down 12% from peak, according to Real Capital Analytics data cited in the report. The nine-quarter average sits at $152.00 per square foot.

Capitalization rates hit an all-time low of 5.0% in Q4 2022, when the spread between self storage and apartments was at its widest at 52 basis points. Over the past six quarters cap rates have averaged 5.8%.

Among the 40-plus self storage experts in Cushman & Wakefield's investor survey, 56% expect little to no change in cap rates over the next twelve months. The slowing housing market was the top concern at 39% of respondents, followed by interest rates at nearly 35%.

What this means for an operator. A 12% decline from peak values with cap rates settling near 5.8% means the era of buying on the assumption of continued rate growth is over. Value now comes from operations, which means occupancy and rate management, which in turn means demand capture. That is a less exciting thesis than 2021 offered, but it favours operators who execute over operators who simply own.

Largest Storage Markets by Inventory

Using January 2026 Yardi Matrix data published by SpareFoot:

Fayetteville-Springdale-Rogers, Arkansas has the most storage square footage per capita of any US metro.

What this means for an operator. Square feet per capita is the supply-side half of a two-part question. Houston at 11.5 square feet per capita and New York at 4.1 are not comparable markets, and neither figure tells you anything by itself. Pair it with search demand for the same market and you have something closer to a real assessment: a market with high square footage per capita and weak search demand is genuinely saturated, while high square footage against strong demand simply means a large, active market.

How to Use These Statistics in Your Own Market

National statistics set context and mislead when used as targets. Three practical moves turn the numbers above into something usable.

Start with your own market's demand rather than the national aggregate. The 1.2 million monthly searches figure is meaningless for your facility; the volume in your city and the cost per click your competitors are paying is not. Both are free to look up in the Demand Index.

Compare against the right benchmark. If REIT occupancy sits near 87.7% while broad stabilized occupancy is 77.0%, the relevant question is which set of operators you actually compete with, and the answer is usually whoever appears above you in local search results.

Separate what you cannot change from what you can. You cannot fix regional oversupply, falling street rates or interest rates. You can fix whether renters searching in your radius this month find your facility before they find the one down the road. When demand exists in your market and your units are not full, the gap is almost always visibility, and you can measure that directly with the free Visibility Grader.
