FAQs About Portable Storage Units in South Carolina

Portable self-storage buildings offer greater flexibility, faster permitting, and the ability to relocate units as needed. They can be quickly deployed, making them an excellent option for businesses or property owners who need storage solutions without the delays associated with constructing permanent structures.

Unlike traditional self-storage units that require on-site construction, our portable mini-storage units are shipped directly from our Indiana location and set in place upon delivery. Once the delivery driver leaves, the units are 100% turnkey and ready to rent. Many of our customers have successfully rented their units the same day they were delivered.

South Carolina has a rich history dating back millennia. For centuries the land was home to the Cherokee, Catawba, and Yemassee peoples before European explorers arrived. In 1521, a Spanish expedition mapped the lowcountry shores, and by 1670 English colonists had founded Charles Towne on Albemarle Point. The colony flourished on rice, indigo, and naval stores, using the skills and labor of enslaved Africans, who forged the distinctive Gullah-Geechee culture along the Sea Islands. South Carolina played a pivotal role in the American Revolution, from the 1776 defense of Sullivan’s Island to the 1780 British victory at Camden. In December 1860 it became the first state to secede from the Union, precipitating the Civil War’s opening shots at Fort Sumter in Charleston Harbor. Reconstruction brought profound social change, while the late 19th century saw textile mills rise along its rivers, ushering in industrialization. The early 20th century welcomed tourism at seaside retreats like Myrtle Beach, and during the Civil Rights era, events at Emanuel AME Church and Seneca’s Friendship Nine marked key milestones. Today, South Carolina balances heritage preservation with urban renewal in places like Greenville and Columbia. Learn more on the official state website and Wikipedia.
