The national self-storage street rate for March 2026 was $131 per month. That number is technically accurate and operationally meaningless for most operators. The national average has been flat or modestly negative for eight consecutive months, and it is now the product of two very different market types canceling each other out: undersupplied, demand-dense cities pushing rates higher, and oversupplied, housing-stalled markets continuing to slide.
RentCafe's March 2026 monthly report, which tracks street rates across 150 of the largest U.S. cities, shows that 76% of those cities posted year-over-year rate declines in March. Twenty-four percent, or 36 cities, posted gains. The national average combines those two groups and produces a figure that describes neither of them accurately.
The 10-by-10 non-climate-controlled unit, the industry's standard pricing benchmark, averaged $119 per month nationally in March, down 0.8% year-over-year. Climate-controlled 10-by-10s averaged $134 per month, approximately flat year-over-year. Both figures have been in a narrow range since late 2025, which looks like stability until you examine the city-level data beneath it.
Which Cities Are Growing and Why
Boston leads every other major market in March 2026 with a 9.7% year-over-year street rate increase, bringing the city average to $223 per month. The gain is consistent with Boston's supply position: the metro has seen minimal new self-storage construction relative to its population density, and demand has held as housing affordability constraints continue to limit move frequency. A tenant who cannot afford to upsize their apartment is a tenant who needs more storage, and Boston has the household density to generate that demand at scale.
The other cities showing strong year-over-year gains follow a similar logic. Coastal metros with limited land for new development, strong professional employment, and below-average construction pipelines have been holding or gaining. The constraint on new supply in these markets, which reflects both zoning complexity and the economics of construction at current land costs and interest rates, is the primary driver of pricing power.
The Northeast region as a whole has been the strongest-performing area for street rates throughout 2025 and into 2026. Markets like suburban New Jersey, outer Boston, and mid-size New England metros have not seen the supply additions that characterized Sun Belt growth markets over the same period. That supply absence is now showing up in the rate data.
Where Rates Are Falling Fastest and What It Signals
Santa Rosa, California posted the steepest year-over-year decline among major markets in March 2026, with rates falling 9.8% to $166 per month. St. Petersburg, Florida declined 8.6% year-over-year to $152 per month, with an additional 2.3% month-over-month drop, the steepest single-month decline in the bottom five. Lubbock, Texas dropped 6.7% annually to $102 per month.
These markets share two characteristics: they absorbed significant new self-storage supply between 2022 and 2025, and their underlying housing activity has slowed materially. The combination produces persistent oversupply without the demand recovery that would typically absorb it. An operator in St. Petersburg competing for new tenants is pricing against facilities built in 2023 and 2024 that are still in lease-up mode, in a market where the relocation-driven move-in volume that used to underpin the sector has declined sharply.
Florida's situation is notable. The state that saw the most dramatic migration inflows during 2020 through 2022 is now experiencing a reversal. Florida's net migration inflows are down more than 90% from 2022 peaks. The self-storage facilities built to serve a growth wave that has largely stalled are now competing for a tenant pool that is not expanding.
Sun Belt markets broadly, including Sarasota, Cape Coral, Charlotte, Dallas suburbs, Phoenix exurbs, and Orlando, have moved into a second year of rate pressure. Facilities in these markets that were built with 2022-era projections about continued migration and housing turnover are operating in a fundamentally different environment than the one their underwriting assumed.
The Extremes Tell the Real Story
The national pricing range in March 2026 runs from $54 per month in Montgomery, Alabama to $309 per month in Honolulu, Hawaii. That $255 spread is the real story the national average conceals. San Rafael, California sits at $304 per month, followed by Santa Barbara, California at $296. On the low end, Denham Springs, Louisiana averages $55 and Peoria, Illinois averages $57.
This spread is not primarily about cost of living. It is about supply constraint, land availability, and local demand density. Honolulu's pricing power comes from an island geography that makes new self-storage construction genuinely difficult and expensive, combined with a high-density population that generates consistent demand. Montgomery's pricing reflects an abundance of available land, lower construction costs, and a lower household income base.
The practical implication for operators evaluating acquisitions or new development is that city-level street rate data, not national averages, should drive underwriting. A national average that says the market is flat says nothing about whether a specific metro is at $166 and falling or $223 and rising. Those are different businesses in different trajectories, and the national figure does not distinguish between them.
The Housing Lock-In Factor Is Structural, Not Cyclical
The demand driver sitting underneath this divergence pattern is the housing market freeze. Elevated mortgage rates have locked millions of households into homes that no longer fit their needs. A household that would have moved to a larger apartment or bought a starter home under pre-2022 rate conditions is instead staying put and, in many cases, renting a storage unit to manage the overflow. SpareFoot data indicates 16% of Americans have already rented a self-storage unit to cope with a home size mismatch, and an additional 25% are actively considering it.
This demand pattern does not produce the move-triggered storage rental that dominated the sector during 2020 through 2022. It produces a slower-moving, longer-duration rental cycle: tenants staying because they cannot afford to solve their storage problem through a home purchase or larger apartment. Average customer length of stay reached 18.5 months in 2026, approximately double the pre-pandemic norm.
The cities benefiting most from this structural demand are the ones where household incomes are high enough to afford storage costs as a substitute for moving, where renter populations are dense enough to generate volume, and where new supply has not arrived to dilute the pricing environment. Boston, coastal California metro areas with constrained pipelines, and select Northeast suburban markets fit this profile. Rapidly growing Sun Belt markets that attracted supply investment alongside migration inflows do not, because the migration has slowed while the supply completed.

The National Average Is Not a Market
Every self-storage operator reading a national average and trying to determine whether conditions are improving is looking at the wrong number. The $131 national figure in March 2026 is the product of Boston and Honolulu pulling rates up, Santa Rosa and St. Petersburg pushing them down, and the sum of many moderately declining Sun Belt markets outweighing the gains in constrained coastal metros.
The market operators are actually in is their city, their submarket, and their competitive set. The rate trajectory in that specific market is shaped by local supply deliveries, local housing activity, and local household income dynamics. In 36 cities, that trajectory is positive. In 114, it is not. Knowing which category a specific facility sits in is more valuable than any national data point.
