Storage unit prices in Phoenix, AZ

In Phoenix the town line does most of the pricing. A 10x10 runs a median $37 across Peoria's branches and $102 across Tempe's, 176% apart before any single branch is compared.

The Phoenix market reaches 15 further towns: Avondale, Cave Creek, Chandler, Fountain Hills, Glendale, Goodyear, Laveen, Laveen Village, Litchfield Park, Peoria, Scottsdale, Sun City, Surprise, Tempe, Youngtown.

The cheapest branch here and the dearest are 456% apart on what they will let you in at: $27 for a 10x10 on 91st Avenue in Peoria, $150 for the same size on Broadway in Tempe.
Public Storage publishes a review score for each branch. Across Phoenix they run from 3.9 on Cactus in Glendale to 4.9 on Avondale in Avondale.
Rates here land 22% under the US median, so what moves them is the region rather than any one address.
That $27 rests on one address. The next cheapest branch, Camelback in Litchfield Park, wants $34, so a unit gone from the first is a 26% jump rather than a short walk.

Where these numbers come from. 453 advertised prices read from Public Storage's own published listings across 71 locations, last checked 2026-08-12.

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.
