Self-storage acquired net rentable square feet measures the rentable storage area added through completed property acquisitions during a stated period.

It is an acquisition-volume measure, not organic same-store growth.

Acquired square feet show external growth in physical terms

Public Storage acquired 87 self-storage facilities containing 6.1 million net rentable square feet during 2025 for $945.6 million.

In the first quarter of 2026, it acquired three facilities containing 0.2 million net rentable square feet for $20.8 million and disclosed additional facilities acquired or under contract after quarter-end.

Square footage adds a physical scale dimension that purchase price alone cannot provide.

Acquisition volume should be separated from development

Purchased facilities can begin contributing revenue immediately, though acquired properties may still require lease-up or operational changes.

New development and expansion projects follow a different capital and stabilization path.

That is why acquisition square feet should be read separately from Self-Storage Development and Expansion Pipeline Square Feet.

Quality matters more than raw square footage

Location, occupancy, current rent, required capital spending, market supply, and acquisition price all affect the economics of an acquired portfolio.

More square footage is not automatically more value.

Primary-source examples

Self-storage acquired net rentable square feet is most useful as an external owned-portfolio growth measure. Read it with acquisition cost, occupancy, lease-up needs, and same-store eligibility timing.

Part of the Self-Storage Operating Model

Connect move-in and move-out pricing, churn, occupancy, same-store NOI growth and margin, rent per occupied square foot, tenant reinsurance, acquisitions, development pipeline, and third-party management scale to understand self-storage economics and portfolio growth.

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.
  • Portfolio scale, margin, and external growth: Same-store rent per occupied square foot and same-store NOI margin add current monetization and property-margin context. Acquired net rentable square feet and development-and-expansion pipeline square feet show owned portfolio growth, while third-party managed store count and rentable square feet show fee-based platform reach beyond the consolidated portfolio. These issuer-defined measures add portfolio-scale and growth context rather than forming a standardized cross-company formula.
