Self storage cost in 2026: what the index actually shows
This page used to open with a national 10x10 average and a year-on-year percentage. Both were our own estimate rather than a measurement, and they came off on 7 September 2026. What is here instead is the one national price series anyone can check for free, running back to December 2003, and the rent figures the largest operator discloses in its own annual report. Neither is a price for a unit. Between them they answer the question this page exists for, which is not what storage costs but which way it is going.

What changed here on 7 September 2026
A national 10x10 average and its climate-controlled counterpart came off this page, along with the year-on-year percentage in the heading and the standfirst, the seven-year table of national dollar averages, the 2026 size grid with its six standard and six climate bands, a 2027 dollar forecast, and the city figures in the FAQ. All were our own estimate presented as measurement. The stale FY2024 rent figures for Public Storage were replaced with the FY2025 ones read at source. Nothing has been invented to fill the gap: the trend table below now shows the free public index instead, which is a real series and is labelled as an index rather than dressed up as a dollar figure.
Why there is no national average here
No free primary source publishes US self-storage rates by unit size. The averages this page used to carry were assembled by us and described as aggregated from consumer-facing operator rates, which is both a basis we cannot show you and one that those operators' terms do not permit us to collect or republish. A number with that provenance is an opinion wearing a measurement's clothes, and on a page whose title is a year it ages badly and quietly.
What can be checked is the direction, and on that the picture is the opposite of what most 2026 price pages imply. The US Bureau of Labor Statistics producer price index for self-storage operators stood at 185.5 in July 2026, up 1.4 percent on the year but still 7.5 percent below its December 2023 peak of 200.6. The industry is recovering from a fall, not extending a boom. It remains 24.5 percent above January 2020 on the same measure, so the pandemic-era step up has not reversed either.
The filings tell the same story from the other end. Public Storage's Form 10-K, FY2025 reports realized annual rent of $22.54 per occupied square foot across its Same Store Facilities, against $22.43 the year before, a rise of 0.5%, at 92.0% average occupancy from 92.4%. That is a large, audited operator putting through a low single-digit increase on a slightly emptier portfolio. It is not a price for any unit, and it must not be multiplied out into one, because it blends every size and market the company operates.
One structural point survives the removal of the averages, and it is the most useful thing on this page: a national figure would mislead you even if it were accurate, because the spread between two metros is several times over for the same box of air, and the spread between two facilities in one city is wider than most people expect. The state page covers the geography, and the way to get your own number is three sites near you in the same week, compared on the month-two rate.

The trend, on the one series that is actually published
Calendar-year averages of the US Bureau of Labor Statistics monthly index for miniwarehouse and self-storage operators, series PCU531130531130. The year-on-year column is computed from the column beside it rather than typed. This replaced a table of national dollar averages that had no source behind it.

Two things this table is not. It is not a dollar figure, and we do not convert it into one, because that needs a per-square-foot assumption we would be inventing. And it is size-blind and national: a 5x5 and a 10x30 sit inside the same series, and the gap between two metros is far wider than anything the index shows.

The size grid that used to sit here
A six-row table gave a standard band, a climate band and a year-on-year percentage for every size from 5x5 to 10x30. Every one of those eighteen figures was hand-typed, and the same bands were being published on six other pages of this site, which is how a single editorial guess came to look like a corroborated fact. They were withdrawn everywhere on 7 September 2026.
What replaces them is not another table. It is the argument that made the table look plausible in the first place, which you can test against your own quotes in one phone call: the fixed costs of a unit, its door, lock, light, aisle frontage and share of security and administration, land once per unit and do not scale with the floor. So the smallest sizes are always the dearest per square foot, a 5x10 is never twice a 5x5, and the curve flattens above roughly 200 square feet where availability rather than area sets the price. The size guide works through that in full, ranked rather than priced.
Three big industry shifts in 2026
REIT consolidation reshaped the chain landscape. Two mega-mergers redrew the top of the industry. The 2023 Extra Space-Life Storage merger combined the second and fourth largest US operators into one, creating an Extra Space portfolio of roughly 4,300 operated stores, about 2,000 of them wholly owned and the balance managed or in joint ventures (rebranded to the Extra Space name from August 2024, with rates generally pulled up 5 to 15 percent toward EXR levels). Then in July 2026 Public Storage completed its roughly $10.5 billion all-stock acquisition of National Storage Affiliates, absorbing another top-six operator's 1,000-plus stores and taking its own portfolio to about 4,500 stores, edging back past Extra Space to reclaim the largest-by-store-count title. The implication for renters is that the 2026 chain landscape has two very large premium operators (PSA, EXR) and one value operator (CubeSmart), with U-Haul as the price-locked alternative, and one fewer independent national brand (NSA) than a year ago.
Peer-to-peer storage has gone mainstream. Neighbor.com and similar platforms have grown rapidly, with 2026 estimates putting peer-to-peer at 5 to 10 percent of the residential storage market in major US metros, up from 1 to 2 percent in 2020. The growth has put modest competitive pressure on traditional facility pricing, particularly in the small-unit segment (5x5 and 5x10 equivalents) where peer-to-peer offers compelling savings. Traditional operators have responded with more aggressive promotional pricing on smaller units rather than direct rate cuts on the asking rate.
Demand normalised post-pandemic. The pandemic-era demand surge that drove 2021-2022 pricing has fully unwound. Industry occupancy rates returned to pre-pandemic norms (88 to 90 percent nationally) by 2024-2025 and are stable in 2026. The 2026 modest price increase reflects normal inflation pressure on a stable demand base, not a return to the pandemic-era growth trajectory. Forecasters expect continued 2 to 5 percent annual increases through 2027-2028 unless macro conditions shift meaningfully.
