New Supply Is Reshaping Storage Markets—Here's What That Means for You
Self-storage development has been one of the most discussed dynamics in the industry over the past several years—and for good reason. The pace of new supply delivery has been significant, and its effects on local market conditions have been uneven. For some owners, the supply wave has passed with minimal impact. For others, it created meaningful pressure on occupancy and rent. And for many, the trajectory of that supply wave is now changing in ways that matter.
The Development Cycle in Numbers
New self-storage construction accelerated sharply between 2019 and 2023, fueled by historically low financing costs, strong facility performance data, and aggressive institutional interest in expanding storage footprints.
The pace of new delivery reached its peak around 2023–2024. According to Yardibreeze's 2026 state of self-storage analysis, new supply in 2025 represented approximately 3.0% of total existing storage stock—already elevated compared to historical norms. The forecast for 2026 is notably more modest: new deliveries are expected to fall to approximately 2.4% of total stock, compared to a long-term historical average of around 4.2% in prior cycles.
That declining pipeline is meaningful. Higher interest rates, elevated construction costs, tighter development financing, and more cautious developer sentiment have all contributed to a substantially thinner forward supply queue. As of late 2025, the active under-construction pipeline nationally was approximately 52.96 million net rentable square feet—significant in absolute terms, but concentrated in specific markets rather than distributed broadly.
Where Supply Pressure Has Been Most Acute
The supply wave hit different markets very differently. Sun Belt metros—Phoenix, Austin, Dallas-Fort Worth, Charlotte, Nashville, Atlanta, Tampa—attracted the most aggressive development activity. These markets offered favorable construction economics, population growth, and strong historical storage demand. But the cumulative effect of multiple new facilities opening simultaneously in many of these submarkets created occupancy softening and rent compression.
According to StorageCafe and RentCafe data, Sun Belt markets with storage inventory exceeding 8 square feet per capita have faced the most persistent downward pressure on rates. For reference, the national benchmark for a balanced market is approximately 7 square feet per capita. Markets that have exceeded that threshold—particularly in submarkets where population growth cooled from pandemic-era highs—have seen the most pronounced pricing pressure.
Looking ahead, eight of the top ten cities for forecasted new storage development in 2026 are located in Sun Belt markets, according to Yardibreeze—even in areas that are already well-supplied. This continued construction activity in already-pressured markets is worth monitoring for owners in those regions.
By contrast, markets in the Northeast, parts of the Mid-Atlantic, and other areas with structural development barriers—zoning complexity, high land costs, entitlement challenges—saw far less new supply and have maintained tighter fundamentals throughout this cycle.
What Supply Does to NOI and Valuation
When supply enters your market and increases competitive pressure, the effects flow directly through your income statement:
Occupancy may decline as tenants have more options and new facilities offer competitive pricing to fill units. National stabilized occupancy ran at approximately 77.0% in Q4 2025 per SkyView Advisors—a figure that reflects markets at various stages of supply absorption.
Street rates may compress if competitors lower pricing to attract move-ins. Widespread move-in specials are a reliable signal of supply-demand imbalance in a submarket.
Revenue growth stalls or reverses as the combination of occupancy pressure and rate softness reduces top-line performance.
Buyers discount for risk when they see a market with significant new supply or an active pipeline. Even if your facility isn't yet affected, the threat of nearby competition factors into buyer underwriting.
The connection to valuation is direct: if your NOI declines due to supply-driven pressure, your facility's value declines proportionally at whatever cap rate applies.
The Absorption Question
Supply overhang is a timing issue as much as a fundamental one. Demand for storage doesn't disappear when new supply enters—it grows over time as a market's population expands and demographic drivers continue. The question is how long it takes for the market to absorb the new units and return to equilibrium occupancy.
Markets with strong underlying demand drivers—population growth, household formation, income growth—tend to absorb supply more quickly. Markets where demand is more static take longer. The declining 2026 construction forecast suggests that for many markets, the most challenging supply period may be behind them—though absorption timelines vary widely by submarket.
What This Means for Your Decision-Making
If your facility is in a submarket that has already absorbed its development wave and returned to healthy occupancy, the supply story may actually be a tailwind going forward—the pipeline is thinner, and fewer new competitors are coming.
If you're in a market still working through absorption, the question is whether you're closer to the beginning or the end of that process. That assessment directly informs whether near-term patience or proactive action makes more sense for your exit timeline.
Advisors who track supply data at the submarket level—tracking not just what's been built, but what's under construction and what's been entitled—can give you a much more precise read than national data alone provides.
