How Extra Space Storage Works and What to Expect

What Extra Space Storage offers and how it operates

Extra Space Storage is a national chain of self-storage facilities with locations across the United States, including several in South Carolina. The company rents climate-controlled and standard units in various sizes—from small lockers to large rooms that can hold the contents of a multi-bedroom house. You rent a unit by the month, pay a monthly fee, and keep your own key or access card. The facility provides the building and security; you decide what goes inside and how long you keep it.

Extra Space Storage operates differently from a moving company or a warehouse service. You load and unload your own belongings, and you control access to your unit during the facility's posted hours. Most locations offer 24-hour gate access for renters, though office hours for signing up or paying in person are typically more limited. The company does not move items for you, store them on your behalf, or manage what you keep inside—that is entirely your responsibility.

South Carolina has Extra Space Storage locations in cities including Charleston, Columbia, Greenville, and Myrtle Beach, among others. You can search for a specific location on their website by zip code or city name to see what unit sizes are available, current pricing, and whether climate control is offered at that facility.

Key Takeaways

• Extra Space Storage charges a monthly rental fee for a unit you access yourself; prices vary by location, unit size, and whether climate control is included.
• You are responsible for loading, unloading, and securing your own items; the facility provides the locked space and building security.
• Most South Carolina locations offer 24-hour gate access for renters, though office hours for new rentals or payment are more limited.
• Climate-controlled units cost more than standard units but protect items sensitive to heat, humidity, or temperature swings.
• Move-in specials and promotional rates are common, but the advertised price often applies only to the first month or first few months.

Unit sizes and what they typically hold

Extra Space Storage offers units ranging from 5x5 feet (roughly 25 square feet) to 10x30 feet (300 square feet) or larger, depending on the location. A 5x5 unit fits seasonal items, a few boxes, or small furniture pieces. A 10x10 unit—one of the most common sizes—holds the contents of a one-bedroom apartment, including a bed, dresser, desk, and boxes of household goods. A 10x15 or 10x20 unit accommodates a two-bedroom apartment's worth of furniture and boxes.

The company's website lets you estimate unit size by describing what you plan to store—furniture type, number of boxes, appliances—and it will suggest a size. This is a rough guide; actual space needs depend on how you arrange items and whether you stack boxes efficiently. Many renters find it helpful to visit the facility in person before committing, so they can see an empty unit and visualize their belongings inside.

Climate control versus standard units

A climate-controlled unit maintains a temperature range (typically 55 to 85 degrees Fahrenheit) and reduces humidity. A standard unit is not heated or cooled and experiences the full range of South Carolina's seasonal temperatures and humidity. Climate control costs significantly more per month—often 50 to 100 percent more than a standard unit of the same size—but protects items that degrade in heat or moisture.

Climate control is worth the cost if you are storing wood furniture, electronics, photographs, documents, artwork, leather goods, or anything sensitive to temperature swings or mold. Standard units work for items that tolerate heat and humidity: metal tools, plastic storage bins, seasonal outdoor equipment, or items you plan to retrieve within a few months. South Carolina's hot, humid summers and mild winters mean standard units can pose a risk to sensitive items over time, particularly if stored for more than a season.

How pricing works and what affects your monthly cost

Extra Space Storage's monthly rent depends on the facility's location, the unit size, whether climate control is included, and current market demand. A 5x5 standard unit in a smaller South Carolina town may cost $40 to $60 per month, while the same size in Charleston or Greenville could run $70 to $100 or more. A 10x10 climate-controlled unit in a major city can exceed $150 per month. These are estimates; actual prices vary widely and change frequently.

The company often advertises a promotional rate for the first month or first three months—sometimes as low as $1 for the first month. This rate is temporary. After the promotional period ends, your rent increases to the standard rate, which is typically what you would have paid without the promotion. Read the rental agreement carefully to see when the promotional rate expires and what your regular monthly payment will be. Some facilities also charge a one-time administrative or facility fee at move-in, separate from the first month's rent.

Insurance, locks, and other add-ons are usually not included in the base rent. Extra Space Storage sells locks and insurance through the facility, or you can bring your own lock (though the facility may have restrictions on lock type). Renters' insurance through the facility typically costs $10 to $20 per month and covers your belongings against theft, fire, or weather damage; your homeowners or renters policy may or may not cover items in storage, so check before assuming you are protected.

How to rent a unit and what to bring

To rent a unit, visit the Extra Space Storage website, search for a location near you, and check availability and pricing. You can reserve a unit online or call the facility directly. Most locations allow you to complete the rental agreement online or in person at the office. You will need a valid photo ID and a payment method (credit card or bank account). Some facilities require a deposit equal to one month's rent, though this varies by location.

On move-in day, you receive a key or access card and the gate code (if applicable). Bring your own moving supplies—boxes, tape, dollies, blankets—or purchase them from the facility if available. The facility does not provide these items. You can move in during the facility's posted hours, which are usually 6 a.m. to 10 p.m. or similar; 24-hour gate access typically applies only after you have completed the rental agreement and received your key.

Keep your rental agreement, key, and gate code in a safe place. If you lose your key, the facility can issue a replacement for a fee. If you forget your gate code, call the facility to confirm it. Most locations allow you to pay rent online, by phone, or in person at the office; set up automatic payments to avoid late fees.

Rules, restrictions, and what you cannot store

Extra Space Storage prohibits storing hazardous materials, including gasoline, propane, paint thinner, batteries, fireworks, and other flammable or toxic substances. You also cannot store perishable food, live animals, or items that produce odors. Firearms and ammunition are prohibited at most locations. Stolen goods and illegal items are not permitted. The facility reserves the right to inspect units if there is evidence of prohibited items or if rent is overdue.

Most facilities have rules about how you can access your unit—typically during posted hours only, and you cannot live in or use the unit as a residence. Some locations restrict commercial use or require a separate commercial storage agreement if you are storing business inventory. Check your specific facility's rules before signing the agreement; they are usually listed on the website or provided at the office.

Month-to-month rental terms and ending your lease

Extra Space Storage units are rented on a month-to-month basis, meaning you pay for one month at a time and can leave whenever you want, as long as you provide notice and pay any remaining rent owed. The notice period is typically 30 days; check your rental agreement for the exact requirement. If you do not provide notice and simply stop paying, the facility will eventually place a lien on your belongings and may auction them off to cover unpaid rent and fees—a process governed by South Carolina's self-storage lien law.

To end your rental, contact the facility office, provide the required notice, remove all your belongings, and return your key. The facility will inspect the unit for damage beyond normal wear and tear. If there is damage, you may be charged a cleaning or repair fee. Once the unit is empty and inspected, your rental ends and you stop paying rent.

Frequently Asked Questions

Can I access my unit anytime, or are there restrictions?

Most Extra Space Storage locations offer 24-hour gate access for renters, so you can enter the facility grounds anytime. However, you can only access your individual unit during posted office hours unless you have a 24-hour access code. Check with your specific location to confirm their access policy, as it varies by facility.

What happens if I do not pay my rent?

If rent is overdue, the facility will charge a late fee and may lock your unit, preventing access. If you do not pay within the timeframe specified in your rental agreement (usually 30 to 60 days), South Carolina law allows the facility to place a lien on your belongings and eventually auction them to cover unpaid rent and fees. Contact the facility immediately if you cannot pay on time to discuss options.

Can I store my car or motorcycle at Extra Space Storage?

Most Extra Space Storage locations do not rent outdoor parking spaces or vehicle storage. Some facilities may have a separate vehicle storage option, but this is not standard. Call your local facility to ask whether vehicle storage is available; if not, they may be able to refer you to another storage company that offers it.

Do I need renters insurance for my stored items?

Extra Space Storage is not responsible for theft, fire, weather damage, or other loss unless you purchase their insurance or have coverage through your own homeowners or renters policy. Check your personal policy to see what it covers; many policies exclude items in storage or cover them only partially. The facility's insurance is optional but recommended if your items are valuable or irreplaceable.

How do I know what size unit I need?

Extra Space Storage's website has a size estimator tool where you describe your items and it suggests a unit size. You can also visit the facility in person to see empty units and visualize your belongings inside. If you are unsure, start with a slightly larger unit than you think you need; it is easier to upgrade or downsize after a month than to run out of space immediately.
