Storage unit prices in South Carolina

No single market speaks for South Carolina. Its largest, Columbia, holds only 25% of the 92 locations we price here, so the state median of $81 is an average of 10 places rather than one city's number.

Inside South Carolina

Where these numbers come from. 223 advertised prices read from Public Storage's own published listings across 92 locations in 10 markets, last checked 2026-08-12.

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. Other operators do not publish per-location pricing in a form that can be read. Not affiliated with Public Storage.
