Storage unit prices in San Antonio, TX

San Antonio is a market on paper more than on the ground: 54 of its 59 10x10 branches stand inside San Antonio itself. Price differences here are between streets rather than suburbs, and on entry price they reach 373%.

The market also holds Cibolo, Converse, Helotes, Live Oak and Universal City.

Cheapest 10x10 in San Antonio: $26 on Interstate Highway 35, $39 once the introductory rate lapses. The dearest branch, Loop 1604 in Live Oak, starts at $123.
Bigger is not cheaper by the foot here. The 10x25 works out at $0.43 a square foot against $0.21 for the smaller 10x20.
41 branches list more than one 10x10. Where they do, the second costs 29% above the first at the same address, so the advertised figure is the door the cheapest unit is behind.
That $26 rests on one address. The next cheapest branch, Center Park, wants $35, so a unit gone from the first is a 35% jump rather than a short walk.

Where these numbers come from. 370 advertised prices read from Public Storage's own published listings across 61 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.
