Storage unit prices in Hilton Head Island, SC

Most Hilton Head Island branches advertise several 10x10 units at once, and the second one costs 32% more than the first at the same address. The $37 headline is the entry price, not the shelf.

These prices take in Beaufort as well.

A 10x10 starts at $37 on Parris Island Gateway in Beaufort and at $87 on Dillon. The market median, $79, sits between them before the introductory rate lapses.
That $37 rests on one address. The next cheapest branch, Storage in Beaufort, wants $60, so a unit gone from the first is a 62% jump rather than a short walk.
Bigger is not cheaper by the foot here. The 10x25 works out at $0.45 a square foot against $0.25 for the smaller 10x20.
Rates here land 17% under the US median, so what moves them is the region rather than any one address.

Where these numbers come from. 43 advertised prices read from Public Storage's own published listings across 8 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.
