The South leads the United States in self-storage usage at 12% of regional households, according to List Self Storage's June 30, 2026 analysis of the Self Storage Demand Study. That penetration rate across more than 50 million Southern households equates to roughly 6.1 million active storage renters, the largest absolute user base of any U.S. region. The West follows at 11%, the Midwest at 10.2%, and the Northeast at 9.9%.
National penetration climbed to 12.6% in 2024 per the SSA's 2025 study cycle, up from 11.1% in 2022. Regional demand strength and regional rate performance are not the same metric in 2026.
What Does the Regional Breakdown Show?
List Self Storage published the four-region comparison on June 30, 2026, sourcing Calvary Realty's Brandon Robinson and the Self Storage Demand Study. The usage rates and household counts:
| Region | Household Penetration | Regional Households | Approx. Storage Households |
|---|---|---|---|
| South | 12.0% | 50M+ | ~6.1M |
| West | 11.0% | ~30M | ~3.3M |
| Midwest | 10.2% | ~28M | ~2.8M |
| Northeast | 9.9% | 22M+ | ~2.0M |
The South leads on both percentage and absolute scale. The Northeast trails on penetration despite cities like New York, Boston, and Philadelphia where apartment living and limited in-unit space would seem to favor off-site storage.
Robinson's analysis, published on List Self Storage, attributes Southern outperformance to rapid population growth in Texas, Florida, Georgia, and the Carolinas, plus military communities, seasonal residents, and expanding suburban development that generates relocation-driven demand.
Why Is the West Second Despite Housing Cost Pressure?
The West's 11% penetration across roughly 30 million households produces about 3.3 million storage users. List Self Storage cites high housing costs in Los Angeles, San Francisco, Seattle, and San Diego as a driver: smaller living spaces push belongings off-site.
Loan analytics data cited in industry research projects the western U.S. as the fastest-growing region by revenue CAGR through 2030 at roughly 7.2%, while the South accounts for about 39% of national market share by revenue. The West combines dense urban demand with migration inflows that sustain household formation even when for-sale housing turnover stalls.
That demand profile helps explain why Turnbull Equity closed a two-property Inland Empire portfolio at a 9.1% going-in cap in June 2026 while buyers in oversupplied Hill Country pockets like Spicewood, Texas, face 52.49 square feet per capita on List Self Storage's June 24-29 transaction roundup. Western demand is real. Local supply still determines returns.
What Holds the Northeast Back on Penetration?
The Northeast's 9.9% rate is the lowest among four major regions, yet it is not far behind the Midwest's 10.2%. Dense urban environments, apartment-heavy housing stock, and limited residential storage still support roughly 2 million renting households.
The gap versus the South is partly structural. Southern states absorbed outsized migration during the pandemic and post-pandemic years, accelerating first-time storage usage among relocating households. Northeast markets already had mature storage penetration in suburban corridors; new growth concentrates in infill conversions and retail adaptive reuse rather than household formation alone.
Rate data confirms the Northeast is not a weak pricing region. Yardi Matrix's May 2026 report showed Boston leading top-30 metros with 2.1% month-over-month advertised rate growth to $20.16 per square foot. Multi-Housing News cited New York City at $34.74 per square foot with a 1.0% sequential gain the same month.
Low penetration plus tight supply explains why Horizon Storage paid up for an 87% leased Westchester conversion with 4 net rentable square feet per capita within three miles, even as the Northeast usage rate trails the South.
How Does National Penetration Square With Sun Belt Rate Pressure?
The SSA's 2025 Demand Study, fielded February through March 2025 across more than 10,000 household screens and 3,456 in-depth renter surveys, measured national penetration at 12.6% for 2024. That continues a two-decade climb from roughly 6% in 2000 and 11.1% in 2022 documented across prior study editions.
Demand is rising nationally. Advertised rates are not uniform regionally. Yardi Matrix's June 2026 national report documented year-over-year advertised rate declines of 1.8% in May 2026 while month-over-month rates rose 0.8%, with supply-heavy Sun Belt metros including Tampa, Sarasota-Cape Coral, Orlando, and Las Vegas lagging on year-over-year growth.
Southwest Florida's July 2026 StorTrack snapshot compresses the paradox into one state: Naples commands $1.91 per square foot on 9.07 square feet per capita while Cape Coral faces 471,280 square feet of scheduled 2026 deliveries. The South leads on household usage. Individual MSAs inside the South diverge sharply on pricing power.
What Should Investors Do With Regional Demand Data?
Do not conflate penetration with cap rate. A region can lead on household usage while specific MSAs inside that region face supply hangover. Underwrite at the MSA and submarket level, not the census region.
Track absolute household counts, not just percentages. The South's 6.1 million storage households represent more than three times the Northeast's ~2 million users. Revenue scale lives in absolute numbers when building platform density.
Pair demand data with drive-time analysis. The SSA's 2025 study found 68% of tenants travel under 20 minutes to their unit. List Self Storage's June 2026 drive-time breakdown showed 33% of customers within 10 minutes. Regional penetration tells you the customer exists. Trade-area geometry tells you whether your site captures them.
Watch demographic tailwinds. Millennial storage usage surged 22% from 2023 to 2025 per the same demand study cycle. Regional growth rates will shift as younger cohorts enter peak storage usage years, but the South's migration and formation advantage is not disappearing in a single rate cycle.
The Numbers Worth Writing Down
- South penetration: 12.0% (~6.1M households on 50M+ base)
- West penetration: 11.0% (~3.3M households on ~30M base)
- Midwest penetration: 10.2% (~2.8M households on ~28M base)
- Northeast penetration: 9.9% (~2.0M households on 22M+ base)
- National penetration (2024): 12.6% (SSA 2025 Demand Study)
- Prior national reading (2022): 11.1%
- May 2026 national YoY advertised rate change: -1.8% (Yardi Matrix)
- May 2026 national MoM advertised rate change: +0.8% (Yardi Matrix)
- Analysis published: June 30, 2026 (List Self Storage)
Demand Is National. Returns Are Local.
The South's 12% household penetration confirms what migration data already suggested: more Americans store their belongings in Sun Belt and Southeast markets than anywhere else. The West, Midwest, and Northeast follow in a tight band between 9.9% and 11%.
Investors who stop at regional rankings miss the point. The Self Storage Demand Study measures where customers already rent. Yardi Matrix and StorTrack measure what operators can charge them this month. In 2026, those two maps do not match. Build the demand case regionally. Underwrite the deal locally.
