Self Storage Questions Answered: What Renters Ask Most

Every month, thousands of people type the same self-storage questions into Google before they ever set foot in a facility. How much does it cost? What size do I need? Is my stuff actually safe in there? None of it is complicated once someone explains it plainly — but most renters end up piecing the answers together across a dozen browser tabs. Below are the questions we hear most often at Purely Storage, answered in roughly the order people ask them.

How much does a storage unit cost?

There is no single national price, and any article that gives you one is guessing. Rent is set facility by facility and moves with four things:

• Size. The biggest lever. A 5x5 locker and a 10x20 unit are different products at different prices.
• Climate control. Temperature- and humidity-regulated units cost more than standard ones because the building is doing more work.
• Location. Land costs drive rent. A unit in coastal California prices differently than the same unit in Tennessee.
• Timing. Storage demand peaks in late spring and summer alongside moving season. Rates and availability follow it.

The fastest way to get a real number is to pull current rates for the facility nearest you. Our storage unit locator shows what is actually available at each site rather than a national average that may not apply to your market.

What size storage unit do I need?

This is the question people get wrong most often, usually by renting too small. A rough starting point:

• 5x5 — a closet's worth. Boxes, seasonal decor, a few small pieces.
• 5x10 — a studio or dorm room. Mattress set, dresser, boxes.
• 10x10 — a one-bedroom apartment, or two rooms of furniture.
• 10x15 — a two-bedroom home, appliances included.
• 10x20 — a three-bedroom home, or a vehicle.

Two practical notes. First, measure your largest, least-flexible item — a sectional sofa or a treadmill often decides the unit size on its own. Second, a unit you can walk into beats one packed wall to wall, especially if you will be pulling things out over the next year. Our storage unit size guide walks through each size with visual comparisons.

Do I actually need climate control?

Sometimes, and the answer depends far more on what you are storing than on how long. Standard units handle tools, patio furniture, plastic bins, and most garage overflow without trouble. Climate control earns its cost when temperature swings and humidity can cause permanent damage: wood furniture and antiques that warp or crack, electronics, leather, vinyl records, artwork, photo albums, and paper documents.

A useful test: if the item would be unhappy spending a summer in your garage or an attic, put it in a climate-controlled unit. If it lives in your garage already, standard is usually fine.

What can't you store in a storage unit?

Every operator prohibits roughly the same list, and it is shorter than people expect. Off limits: anything hazardous, flammable, explosive, or combustible (gasoline, propane, paint thinner, fireworks); perishable food; living things, including plants and animals; and anything illegal. Nothing that can leak, spoil, or attract pests belongs in a unit, and no one may live in one.

Gray areas worth flagging: appliances need to be fully drained and dried first, lawn equipment needs its fuel emptied, and firearms have their own rules that vary by state. Our self storage FAQ covers the full policy.

Am I locked into a long-term contract?

No. Self storage runs on month-to-month agreements, not annual leases — you rent for as long as you need and give notice when you are done. That flexibility is the whole point of the product, and it is why storage works so well for renovations, deployments, and moves with a gap in the middle. We wrote more about how this works in our guide to month-to-month storage units.

When can I get to my unit?

Access hours are set per facility, so this is worth confirming before you sign. Many locations offer extended hours or 24/7 gate access; others run on daytime hours. You will get a personal gate code, and only you and authorized staff can get into your unit. If you expect to visit at odd hours — contractors and small business owners often do — check the access hours on the individual location page rather than assuming.

Is my stuff insured?

Your rent covers the space, not the contents. Many homeowners and renters policies extend limited off-premises coverage to items in storage, often at a reduced percentage of your main limit, so the first call should be to your existing insurer to ask what is covered and for how much. Most facilities either require proof of coverage or offer a protection plan you can add at move-in. Either way, photograph what goes into the unit and keep a rough inventory. It takes ten minutes and makes any future claim dramatically easier.

How secure are storage facilities?

Modern facilities layer several things: perimeter fencing, gated entry with individual access codes, surveillance cameras, lighting, and on-site staff during business hours. You supply the lock on your own door, and the choice matters — a disc lock resists bolt cutters far better than a standard padlock with an exposed shackle. When you tour a facility, look at whether the lighting is working, whether the drive aisles are clean, and whether someone is actually on site. Those tell you more than a feature list does.

Can I store a car, RV, or boat?

Yes, and it is one of the fastest-growing reasons people rent. Options range from open parking spaces to covered spots to fully enclosed units, and the right one depends on the vehicle and your climate. Purely Storage offers vehicle storage, RV storage, boat storage, and motorcycle storage across several states.

Before you park anything long-term: top off the fuel tank to limit condensation, connect a battery tender or disconnect the battery, inflate tires to spec, and give the interior a thorough cleaning so nothing attracts pests.

How do I keep mold, mildew, and pests out?

Almost every storage horror story traces back to moisture or food. Clean and fully dry everything before it goes in — a slightly damp cushion will find mildew eventually. Use sealed plastic bins instead of cardboard for fabric and paper. Keep everything off the concrete on pallets or shelving so air can move underneath. Leave a few inches between stacks and the walls. And never store food, not even sealed pantry goods. Our post on mold and pest prevention in storage units goes deeper on each of these.

Can a business rent a storage unit?

Regularly. Contractors store tools and materials, e-commerce sellers store inventory, offices store archived files, and seasonal businesses store everything between seasons. A business storage unit costs a fraction of commercial warehouse space and comes with the same month-to-month flexibility. If you will be loading and unloading often, a drive-up unit you can back a van into will save you more time than anything else on the list.

Drive-up or indoor — which is better?

Drive-up units are ground level with a roll-up door you park directly in front of, which makes loading heavy or bulky items enormously easier. Indoor units sit inside a secured building, add a layer between your belongings and the weather, and are where climate control usually lives. Choose drive-up for furniture, equipment, and frequent access; choose indoor for sensitive items and long-term storage. Plenty of people rent one of each.

How far in advance should I reserve?

In slower months, you can often rent the same day. During peak moving season — roughly May through September — popular sizes at busy facilities sell out, and the first few days of the month are the tightest. If your move date is fixed, reserve a week or two out. Reservations are typically free to place and easy to adjust, so there is little downside to booking early.

Still have questions?

These cover the ground most renters need before their first month, but every situation has its own wrinkle.
