Self-storage same-store NOI growth measures the change in net operating income generated by an operator's defined stabilized same-store portfolio.

It is a property-level operating measure designed to reduce distortion from acquisitions, developments, expansions, and lease-up.

NOI combines revenue and property expense

A useful bridge is:

same-store NOI = same-store property revenue - same-store property operating expense

Extra Space Storage reported second-quarter 2026 same-store revenue growth of 2.4%, same-store expense decline of 0.5%, and same-store NOI growth of 3.5%.

The example shows why NOI growth can differ materially from revenue growth when operating expenses move in the opposite direction.

Occupancy and pricing drive the revenue side

Same-store revenue is influenced by:

The same occupancy result can produce different revenue growth depending on the rate environment.

Expense leverage matters

Property taxes, payroll, utilities, repairs, marketing, and other store-level expenses affect NOI.

When revenue grows faster than operating expense, NOI growth can exceed revenue growth.

When costs accelerate, NOI can underperform revenue.

That operating leverage is one reason same-store NOI is a central REIT metric.

Same-store NOI is not total-company profit

NOI generally excludes corporate overhead, depreciation and amortization, interest expense, and other items below the property operating line.

Issuer definitions also differ.

Public Storage and Extra Space caution investors to understand their own same-store pools and non-GAAP definitions rather than assume perfect peer comparability.

Primary-source examples

Self-storage same-store NOI growth is most useful as a stabilized property-profit measure, not as total-company earnings or a standardized accounting metric.

Part of the Self-Storage Operating Model

Connect customer move-in pricing, move-out pricing, churn, stabilized occupancy, same-store NOI growth, and tenant reinsurance to understand self-storage property and ancillary economics.

How the model fits together
  • Customer acquisition, retention, and occupancy: Move-in contract rent shows the price offered to new customers, while move-out contract rent shows the rate paid by departing customers after in-place increases. Same-store churn captures customer turnover, and same-store occupancy shows how those flows translate into stabilized space utilization.
  • Property and ancillary economics: Same-store NOI growth captures stabilized property-level revenue and expense performance, while tenant reinsurance adds a separate ancillary revenue and profit stream tied to insured tenants. Neither measure should be treated as a substitute for occupancy or customer pricing.
