Everything You Need,
Nothing You Don't

We've thought of the details
so you don't have to.

Climate Controlled

South Carolina summers are no joke. Our A/C and heat-controlled units keep your belongings safe year-round from Charleston's notorious humidity.

Video Surveillance

Sleep easy. Our facilities are monitored 24/7 with high-definition security cameras and gated keypad entry for your peace of mind.

Convenient Hours

Office open Mon–Sat, 9am–5:30pm. Gate access available 7 days a week so you can get to your unit when it fits your schedule.

U-Haul Truck Rentals

Reserve a moving truck right at our facility. We're an authorized U-Haul dealer at both locations — one stop, and you're moving.

Boat & RV Storage

Got a boat for the Lowcountry waters or an RV for road trips? We offer dedicated vehicle storage so they stay safe between adventures.

Online Bill Pay

Pay your rent from anywhere, any time. Our secure online portal makes managing your account easy — no trips to the office required.

Packing Supplies

Boxes, bubble wrap, tape, locks — we stock the essentials on-site at both locations so you can grab what you need right when you need it.

Month-to-Month Leases

No long-term contracts required. Flexible month-to-month leasing gives you the freedom to store for as long — or as short — as you need.

Welcome to
Main Road Self Storage

You have wandered off the beaten path and now you are at Main Road Self Storage. We want to introduce ourselves. We are a self-storage facility with two locations — one in Johns Island, South Carolina, and the other in Summerville, South Carolina. With two locations, you may be worried about being stretched too thin, but we have doubled the storage space without doubling the price.

Whether you are upgrading or downsizing, renovating, remodeling, or relocating, we have the best storage options available. We have storage units that are available in a range of sizes, so regardless of how much you need, we can store it all. They also come in various types. There is a standard rental, which is just fine for personal storage, but should you need extra protection, our rentals also come with air conditioning, climate control, and heat. No matter the weather, keep your items safe together.

The main road is always at the heart of every community. At Main Road Self Storage, we strive to be the pulse for the members of our community, and we keep our doors open to accommodate everyone. Visit either one of our locations to see how we can help.

Community-First Values

Family-owned since 1990, we treat every customer like a neighbor — because in most cases, you are one.

Range of Unit Sizes

From 5×5 to 10×20 and beyond — we have the right fit for any storage need.

Month-to-Month Flexibility

No long-term contracts. Rent for as long as you need — and leave when you're ready.

Charleston Storage Tips
You'll Actually Use

Beat the SC Humidity

With summer humidity regularly topping 80%, climate-controlled units aren't a luxury in Charleston — they're essential for protecting wood furniture, electronics, art, and clothing.

Smaller Homes, More Storage

As Charleston and Summerville keep growing, homes stay pricey and garages fill up fast. A storage unit is often the most affordable square footage in town.

Store Your Boat Between Seasons

The Lowcountry's waterways are legendary. When your boat isn't on the water, keep it secure and protected at our Johns Island facility — close to the launch.

What Our Customers Say

Don't just take our word for it — here's what real Charleston-area customers think about Main Road Self Storage.

The Buck Family, owners of Main Road Self Storage

More Than Storage —
We're Your Neighbors

Main Road Self Storage has been a part of the Charleston community since 1990, when the Buck family saw a simple need: people needed a safe, convenient place to store the things that matter to them.

What started as a single facility on Johns Island has grown into two trusted locations serving thousands of families and businesses across the greater Charleston area. But through all that growth, our approach has stayed the same: real people, real service, and a genuine care for every customer who walks through our gate.

When you rent with us, you're not a number in a national chain's database. You're a neighbor — and we treat you like one.
