Where these numbers come from. 944 advertised prices read from Public Storage's own published listings across 144 locations in 3 markets, last checked 2026-08-31.

Online rate vs regular rate. Every listing publishes two figures and the regular rate is 1.5× the online rate at the median. That is a pricing rule, not a second quote. Figures here are the online rate (the promotional price for booking on the web) unless labelled otherwise. Budget on the regular rate.

Advertised rates for new rentals, not quotes; they move with availability. Insurance, admin fees and limited-time offers are excluded. This covers Public Storage only, which is a limit of what is collected here rather than of what exists. Not affiliated with Public Storage.
