Why premium storage is a different product

Self-storage is often discussed as one asset class. In practice the gap between commodity product and premium product is wide enough that they compete for different customers and age in opposite directions.

Conditioning changes the customer

Full climate control throughout — not as a premium tier within a mostly unconditioned building — changes what people store and how long they store it. Longer tenancy and lower sensitivity to rate changes follow from that, and both show up in the asset’s durability well before they show up anywhere else.

Security is a drawing-stage decision

Access control, camera coverage, sightlines, and lighting either get designed in or get retrofitted badly. Facilities that treat security as a specification hold occupancy in ways that facilities treating it as an amenity do not.

Build quality determines who can buy it

The most underappreciated point: construction quality determines the eventual buyer pool. An asset specified to institutional standards underwrites cleanly to an institutional purchaser. An asset built to the minimum viable standard underwrites to whoever will take it, at whatever the market gives that day.

Supply is not uniform

Markets described as saturated frequently are not saturated with this product. Aggregate square footage per capita is a blunt measure that treats a twenty-year-old unconditioned facility as equivalent supply. It usually is not.

The practical consequence is that markets have to be screened on the quality of existing supply, not only its quantity — which is slower, and which is the point.
