➤ Key Highlights
2026 deliveries projected at ~51.1M SF, down from 55.1M SF in 2025.
Deliveries forecast to fall ~18% in 2026 and ~8% in 2027.
New supply drops to ~2.4% of total stock, vs. a long-term average of 4.2%.
Drivers: higher financing costs, slower rent growth, longer entitlements, elevated construction costs.
Developers are narrowing focus to growth Sun Belt metros and select secondary markets.
➤ SIGNAL
The supply correction is policy-driven and durable, not a one-quarter dip.
Below-average new starts protect existing owners’ occupancy.
Saturation risk is now local, not national.
Self-storage spent the last cycle over-building into demand. The 2026 pullback flips that: with new supply at roughly 2.4% of stock — barely half the historical norm — the sector is rebalancing toward the operators who already own the assets.
The headwinds keeping starts down are structural. Costly debt, harder-to-raise equity demanding higher returns, longer and less certain entitlement timelines, and elevated construction costs all push new feasibility further out. None reverses quickly.
For existing portfolios in supply-disciplined submarkets, thinning competition is the quiet tailwind — rent growth has cooled, but a starved pipeline limits how much new product can undercut them. The underwriting edge has moved from development to acquisition and lease-up of standing assets in markets where the pipeline is genuinely empty; pro formas built on continued heavy supply growth are now stale. The constraint is delivery, not demand.
➤ TAKEAWAY
When the cranes stop, incumbents win — self-storage just handed pricing power back to the operators who already own it.
