Self-Storage Construction Cools in 2025, But Sunbelt Leaders Still Add Big Space – Atlanta, Phoenix Top U.S. Metros

Self-Storage Construction

NATIONWIDE (January 6, 2026) – After a pandemic-era building surge, the U.S. self-storage sector shifted into cautious optimism in 2025, with developers pulling back to restore balance between supply and demand. New deliveries totaled 51 million square feet of rentable space nationwide last year – about 2.4% of existing inventory – marking a 21% decline from 2024 and signaling a deliberate recalibration rather than a full stop.

South and Southwest Dominate New Supply

Supply growth was heavily concentrated in the South and Southwest, with Florida, Texas, California, Georgia, and North Carolina leading. Florida stood out as the most significant gainer nationally, with developers delivering nearly 9 million square feet of new self-storage space in 2025, expanding the state’s inventory by roughly 5%. Texas ranked among the most active construction markets, adding approximately 5.1 million square feet, while California ranked third with 4.4 million square feet delivered in 2025.

Florida metros with the largest additions (square feet delivered; inventory growth; average street rate):
  • Orlando: 1,195,200; 5.0%; $126
  • Tampa-St. Petersburg: 1,031,100; 3.8%; $134
  • Jacksonville: 1,008,700; 6.4%; $136
  • Cape Coral-Fort Myers: 924,800; 10.5%; $130
  • Miami: 615,300; 4.1%; $169
  • Deltona-Daytona: 498,600; 7.4%; $123
Atlanta and Phoenix Lead Metro Deliveries

At the metro level, 13 markets recorded more than 1 million square feet of new self-storage deliveries in 2025, led by Atlanta and Phoenix. Both Sunbelt hotspots added more than 2 million square feet each, outpacing the rest of the field by a wide margin. New York-Newark-Jersey City ranked third with 1.7 million square feet delivered, followed by Los Angeles and Chicago.

Even in the most active large metros, new construction generally arrived at a measured pace. Most top-delivery markets expanded inventory by only 2% to 5%, allowing supply to grow without overwhelming local fundamentals.

Smaller Markets See the Sharpest Percentage Swings

While the biggest markets led in total square footage, the fastest inventory changes occurred in smaller metros where new construction can dramatically shift local supply.

  • Elizabeth City, NC: added about 265,900 square feet; inventory up nearly 48.6%
  • Cape Coral-Fort Myers, FL: added 924,800 square feet; inventory up 10.5%
  • Gainesville, FL: added 244,800 square feet; inventory up 10.4%
  • York-Hanover, PA: added 275,600 square feet; inventory up 9.8%
Why the ‘Winners’ Keep Winning

The 2025 pattern reinforces a core thesis of self-storage: demand is often strongest where ‘stuff movement’ is constant. That includes markets fueled by in-migration and relocation churn, suburban growth and household accumulation, high housing costs and space constraints, and seasonal residency and life-event storage.

  • In-migration and relocation churn (Florida, Georgia, North Carolina)
  • Suburban growth and household accumulation (major Texas metros)
  • High housing costs and space constraints (coastal California and dense urban markets)
  • Seasonal residency, downsizing, and life-event storage (many Florida metros)
Heading into 2026: Recovery, Uneven by Market

Industry commentary points to a sector in recovery, with improving absorption and stabilization in markets that entered the cycle with higher initial supply. Rates have been rising since late 2024 in many major metros, while a decline in lease-up supply has helped reduce competitive pressure in numerous locations. Developers and major operators have generally slowed their pace, focusing new projects more selectively on pockets of growing demand and undersupply.

The result is a market approaching an inflection point: oversupply is easing in many locations, rents are stabilizing, and growth strategies are shifting toward careful site selection rather than blanket expansion.
