Self-storage has spent the last two years in a correction — a well-earned one after the most explosive demand surge in the sector’s history. Pandemic-era tailwinds drove occupancy to record highs, rents to all-time peaks, and valuations to levels that left little room for error. When the cycle turned, it corrected hard: asset values fell roughly 25% from peak, rents softened across most major markets, and new supply continued delivering into weakening demand. That correction is now largely behind us. Q1 2026 REIT earnings, transaction data, and pipeline reports all point to the same conclusion: self-storage has found its floor, supply growth is hitting an 11-year low, and the sector’s structural demand drivers remain as strong as ever. For sponsors and capital allocators, this is the setup — not the aftermath.

The Setup: How Self-Storage Got Here

Few asset classes had a more dramatic pandemic run than self-storage. Household dislocation, remote work, life transitions, and a surge in e-commerce created demand that the sector had never seen at scale. Average asking rents hit an all-time high of $134 per unit in 2022. Occupancy reached levels that operators had previously considered theoretical maximums.

Then the cycle turned — as cycles do. Rents began declining in the second half of 2023 amid softening net demand, new supply that had been permitted during the boom, and increased cost sensitivity among tenants. Occupancy rates fell from their peaks and ranged between 89% and 92% through most of 2024 and into 2025.

What makes 2026 different is not that demand has exploded again. It’s that supply has stopped. Construction starts are down 21% from the 2023 peak. The pipeline of new facilities entering the market is the thinnest it has been in over a decade. And demand’s structural drivers — housing churn, life transitions, small-business storage, and the long-term trend toward smaller living spaces — never went away.

What Q1 2026 REIT Earnings Actually Say

The four major self-storage REITs reported Q1 2026 earnings in April and May, and the directional signal across all four is consistent: occupancy gaps are closing, revenue growth is accelerating, and supply pressure is easing. The details matter.

The CEO commentary across all four operators uses the same language: declining supply pressure, improving occupancy trends, and a market where the best existing assets are the primary beneficiaries of constrained new construction. That is not cautious optimism — it is a synchronized signal from the four largest operators in the sector.

Supply Is the Story. And the Numbers Are Stark.

New supply is the single most important variable in self-storage underwriting, and in 2026, it is working in investors’ favor for the first time since the pandemic cycle began.

According to Green Street, supply growth hit an 11-year low in 2025. Construction starts are down 21% from the 2023 peak, with 2025 year-to-date activity trailing the 2024 pace. The drivers of this restraint are structural, not temporary: elevated construction costs, tariff risk on building materials, tighter construction lending, and longer entitlement timelines have all combined to make breaking ground on a new facility a fundamentally different financial calculation than it was in 2019 or 2021.

Extra Space’s management put it plainly on their Q1 earnings call: properties facing new competitive supply declined to 8% of their portfolio in 2025 and are expected to fall to 6% in 2026. That is a meaningful and measurable reduction in the supply headwind that has pressured the sector’s best operators for three years.

For private owners of well-located, quality facilities in supply-constrained markets, this is the backdrop that drives the next two to three years of performance. Absorption of existing units without meaningful new competition is the cleanest path to rent recovery — and the pipeline suggests that path is now open.

Where Markets Are Bifurcating

The national headline numbers — $131/month average street rates, down 2.2% YoY in March 2026 — mask a sharp divergence between supply-constrained and supply-saturated markets that is critical for underwriting.

Boston illustrates the supply-constraint thesis perfectly. With just 0.7 square feet of storage per resident — well below the national benchmark of 7 square feet — and apartment sizes that have shrunk 11% over the past decade, Boston operators are recovering pricing power that most Sun Belt markets won’t see for another 12 to 18 months.

The operator commentary reinforces this bifurcation. CubeSmart’s CEO noted that “our more stable urban markets in the Northeast and Midwest continue to outperform, while our more transient supply-impacted markets across the Sunbelt and the West Coast are beginning to see green shoots.” That phrasing — green shoots — means the turn is beginning, but it is not complete.

The Values Reset — and What Comes Next

Self-storage property values fell approximately 25% from post-pandemic peaks over 12 quarters. For buyers who missed the 2021 cycle top, this reset is not a warning sign — it is an entry point. Green Street’s Commercial Property Price Index shows pricing reached a floor in Q2 2025 and has risen for two consecutive quarters heading into 2026. The repricing phase appears to be ending.

This matters for capital allocators because the sector’s long-term track record is exceptional. Self-storage has outperformed core CRE segments in most years since 2006, including during the 2008 financial crisis and the early months of COVID. The combination of low capital expenditure requirements, operationally intensive but tech-enabled management, and monthly lease structures that allow rapid rent adjustment gives the asset class a resilience profile that most property types cannot match.

Buying a well-located facility today — at or below replacement cost, with occupancy recovering and supply constrained — is structurally similar to buying multifamily in 2012 or industrial in 2016. The institutions know it. Public Storage’s $10.5 billion acquisition of NSA is the loudest possible institutional signal that this is the right moment to be allocating to the sector.

What HB Capital Is Watching

• 1Per-capita supply as the primary underwriting filter. Markets below 5 square feet per capita are the most compelling. Boston at 0.7, New York at under 3, and select Midwest metros are where supply-constrained pricing power lives. Markets above 9–10 square feet per capita require a much longer recovery runway.
• 2Existing facility acquisitions over ground-up development. With construction costs elevated and debt for speculative development scarce, acquiring existing stabilized or value-add facilities at a discount to replacement cost is the dominant strategy. The supply data supports this for at least the next 24 months.
• 3Technology-driven operators commanding premium valuations. Self-storage has undergone a meaningful technology transformation — dynamic pricing, automated kiosks, remote management, and digital-first customer acquisition. Facilities with modern tech infrastructure are achieving higher occupancy and lower expense ratios, and they are trading at a premium. Buyers need to underwrite operational quality, not just location.
• 4Bridge lending as a capital markets opportunity. SmartStop’s launch of a bridge lending JV targeting 10%–14% yields signals that the debt markets for transitional self-storage assets are generating attractive risk-adjusted returns for non-bank lenders. This is a capital deployment opportunity HB Capital is actively tracking for clients seeking yield with collateral backing.

Executive Takeaway

Self-storage is at an inflection point that looks remarkably like the setup that defined the sector’s best vintage years. Values have corrected 25% from peak. Supply growth is at an 11-year low. Occupancy gaps are closing at the REIT level. And the structural demand drivers — housing transitions, shrinking living spaces, small-business storage needs, and an aging population downsizing into smaller homes — are as durable as any demand thesis in commercial real estate.

For sponsors, the playbook is straightforward: acquire below replacement cost in supply-constrained markets, prioritize operational quality and technology infrastructure, and position for the rent recovery that a constrained pipeline will ultimately deliver. For LPs and family offices, this is the vintage moment the sector creates once every decade. The institutions have already signaled where they stand. The $10.5 billion acquisition of NSA is not a forecast — it is a statement.
