Where these numbers come from. 18 advertised prices read from Public
Storage's own published listings across 18 locations, last checked
2026-08-27.
Online rate vs regular rate. Every listing publishes two figures. Measured across thousands of observations, the regular rate is 1.5× the online rate at the median, with 88% inside 1% of that and none outside 1.40–1.60×. That is a pricing rule, not a second quote. The online rate is the promotional price for booking on the web; the regular rate is what the unit reverts to. Budget on the regular rate. Comparisons here hold the basis constant, so the gap between locations is real either way.
These are advertised rates for new rentals, not quotes — Public Storage states prices are not guaranteed and they move with availability. Insurance, admin fees and limited-time offers are not included.
How this is measured. The sampling, the percentile method and the rules for withholding a figure are set out on the methodology page. The figures are published as CC BY 4.0 and may be reused with attribution.
