The average self-storage street rate across the United States was $133 per month in May 2026. That figure combines different unit sizes, locations, and climate-control options, so your actual quote may land well below or above it.
A standard 5×5 unit averages close to $52 per month. A standard 10×10 averages $119. A larger 10×20 averages about $193. Climate control raises the price, especially as the unit gets larger.
Your real cost comes down to 5 questions:
- How much floor space do you need?
- What are you storing?
- How long will you keep the unit?
- How often will you need access?
- What fees sit outside the advertised rate?
That last question deserves more attention than it usually gets.
Quick answer: How much does a storage unit cost in 2026?
Here are national average monthly rates reported at the beginning of 2026.
| Storage unit size | Standard unit | Climate-controlled unit | Common use |
|---|---|---|---|
| 5×5 | $52 | $53 | Boxes, seasonal items, small furniture |
| 5×10 | $74 | $82 | Contents of a small bedroom or studio |
| 10×10 | $119 | $134 | Furniture from a 1- or 2-bedroom home |
| 10×15 | $156 | $179 | Contents of a 2- or 3-bedroom home |
| 10×20 | $193 | $232 | Larger household move, tools, inventory |
| 10×30 | $256 | $327 | Large home, business stock, major equipment |
These are national averages based on Yardi Matrix pricing data. Local demand can move the number sharply in either direction.
A 10×10 unit, for example, averaged about $80 per month in Houston and $219 in Los Angeles in one 2026 national provider’s pricing data. The same square footage can cost nearly 3 times as much because of local land prices, demand, available inventory, and operating expenses.
What size storage unit do you need?
Paying for unused floor space adds up fast. Renting too small creates another problem: you may end up moving everything twice.
Measure the large items first. Count your boxes. Then plan for a narrow aisle if you’ll need to retrieve things during the rental.

5×5 storage unit cost
A standard 5×5 unit averages about $52 per month. A climate-controlled version averages close to $53 per month.
A 5×5 gives you 25 square feet of floor space, roughly the footprint of a hall closet. It works for:
- Holiday decorations
- Small lawn tools
- Camping equipment
- A dresser
- A twin or full mattress
- Several boxes
- Seasonal clothing
- Small business supplies
This size works well when you have a specific pile of belongings rather than a whole room to empty.
5×10 storage unit cost
A standard 5×10 averages about $74 per month. Climate-controlled space averages $82 per month.
A 5×10 has 50 square feet of floor space. It’s about the size of a large walk-in closet and can usually hold the contents of a small bedroom or studio apartment.
For a homeowner, that may mean a mattress, dresser, desk, chairs, and boxes.
For a contractor, it may hold boxed tools, ladders, portable equipment, safety gear, and jobsite supplies. The long, narrow shape can become frustrating if you need something buried at the back, so leave an aisle.
10×10 storage unit cost
A standard 10×10 unit averages $119 per month. A climate-controlled 10×10 averages $134 per month.
This is one of the most commonly rented sizes. You get 100 square feet, usually enough for furniture and boxes from a 1- or 2-bedroom apartment.
A 10×10 may hold:
- Bedroom furniture
- Sofas and chairs
- A dining set
- Small appliances
- Bicycles
- Office equipment
- 50 or more boxes, depending on furniture placement
The square shape is easier to organize than a 5×10. Shelving along one wall and a center aisle can keep frequently used items within reach.
10×15 storage unit cost
A standard 10×15 averages around $156 per month. Climate-controlled space averages about $179 per month.
This size works for a 2- or 3-bedroom move, depending on how much furniture you own. It can also make sense for a contractor who needs room for tools, boxed materials, portable machines, and shelving.
Check the door width before signing. A wide floor plan loses some of its usefulness when large equipment can’t pass through the opening.
10×20 storage unit cost
A standard 10×20 averages about $193 per month. A climate-controlled unit averages $232 per month.
You’re getting 200 square feet, close to the footprint of a small one-car garage. This size can hold the contents of a 3- or 4-bedroom house, depending on how tightly everything is packed.
It can also work for:
- Contractor tools and jobsite equipment
- Retail inventory
- Landscaping machines with drained fuel systems
- Farm parts and boxed supplies
- Office furniture
- Moving and renovation storage
Ask about drive-up access. Carrying a table saw, tool chest, or heavy furniture through an interior hallway gets old quickly.
10×30 storage unit cost
A standard 10×30 averages $256 per month. The climate-controlled average is about $327 per month.
At 300 square feet, this is one of the largest common rental sizes. It may hold a large household move, commercial inventory, or a mix of equipment and supplies.
It also creates a large recurring bill. A standard 10×30 rented at the national average costs $3,072 over 12 months before insurance, administrative charges, locks, taxes, or future rate changes.
Why storage unit prices change from one facility to another
Two facilities can be a few miles apart and charge very different rates.
The building itself is only part of what you’re paying for. Availability, access, security, local property costs, and the type of unit all shape the monthly price.
Your city and neighborhood
Storage costs usually rise in dense markets where land is expensive and households have less space at home.
In May 2026, the nationwide weighted street rate was $133. City averages ranged from about $81 in Montgomery, Alabama, to $280 in Glendale, California, among markets covered in RentCafe’s report.
Search beyond the closest facility. Driving another 10 or 15 minutes may cut the monthly bill, especially around large cities.
Keep fuel and retrieval time in the calculation. A cheaper unit 35 miles away may cost more once you start making weekly trips.
Climate control
Climate control raises construction and operating costs, so renters pay more for it.
The price difference changes by size. January 2026 averages showed:
| Unit size | Standard | Climate controlled | Monthly difference |
|---|---|---|---|
| 5×5 | $52 | $53 | $1 |
| 5×10 | $74 | $82 | $8 |
| 10×10 | $119 | $134 | $15 |
| 10×20 | $193 | $232 | $39 |
| 10×30 | $256 | $327 | $71 |
Climate control makes sense for belongings that react badly to heat, cold, humidity, or condensation. Common examples include wood furniture, electronics, paper records, photographs, leather, musical instruments, and certain business goods.
Plastic patio furniture, metal hand tools, and other temperature-tolerant items may do fine in standard storage when they’re cleaned, dried, and packed correctly.
Ask the facility what “climate controlled” means at that location. Temperature control and humidity control aren’t always the same service.
Not sure whether climate control is worth the added cost? Read our comparison of climate-controlled and non-climate-controlled storage buildings.
Drive-up access
Drive-up units are convenient for heavy or frequently used items. You park beside the door and load directly from the vehicle.
That convenience can raise the rent in busy markets. Indoor upper-floor units may be cheaper, though you’ll have elevators, hallways, and access hours to deal with.
Contractors and small businesses should calculate labor time here. Saving $20 a month loses its appeal when 2 employees spend an extra 30 minutes loading every week.
Ground floor versus upper floor
Ground-floor units often carry a premium because they’re easier to reach. Upper-floor units can cost less, especially in multi-story facilities with plenty of unused space.
Walk the route before renting. Check elevator size, cart availability, doorway width, turning space, and the distance from parking to the unit.
Seasonal demand
Storage demand often rises during spring and summer as more households move, renovate, or relocate for school and work.
Online specials can bring the move-in rate down. Read how long the special lasts. A heavily discounted first month tells you very little about what months 4 through 12 will cost.
The advertised price may leave out several charges
Treat the online rate as the beginning of your calculation.
Depending on the operator and location, your move-in or monthly bill may include:
- A one-time administrative or setup charge
- A lock charge
- Insurance or a tenant-protection plan
- State or local taxes
- Late-payment charges
- Access charges for special hours
- Cleaning or disposal charges after move-out
Extra Space states that taxes and a one-time setup charge can sit outside its advertised monthly rental rate. Some of its facility listings also show separate administrative and lock charges. Public Storage requires customers to carry insurance on stored goods. Requirements differ by company and contract.
Ask for the total amount due on move-in day and the normal recurring monthly total after every promotion ends.
Get both numbers in writing.
Can a storage facility raise your rent?
Many self-storage agreements run month to month. That gives you flexibility to leave, and it gives the operator room to review the rental rate.
Public Storage explains that its rentals use month-to-month agreements and that prices may change over time. The notice requirements depend on your contract and local law.
Ask these questions before moving anything:
- Is this an introductory rate?
- How long is the quoted price guaranteed?
- When can the first increase occur?
- How much notice will I receive?
- Is there a cap on each increase?
- Can I prepay several months at the current rate?
- Does prepayment lock the rate?
Price disclosures deserve close attention. On July 9, 2026, New York City announced a $1.7 million settlement involving allegations of low advertised prices followed by excessive increases and other consumer-protection violations. The case applied to New York City, but the lesson travels well: save the advertisement, lease, payment receipts, and every rate-change notice.
What a storage unit really costs over several years
Monthly rent looks manageable in isolation. The total becomes clearer when you run it across 3 or 5 years.
The calculations below use January 2026 national average standard-unit rates. They exclude insurance, taxes, setup charges, locks, late fees, and rent increases.
| Unit size | Monthly average | 1 year | 3 years | 5 years |
|---|---|---|---|---|
| 5×10 | $74 | $888 | $2,664 | $4,440 |
| 10×10 | $119 | $1,428 | $4,284 | $7,140 |
| 10×20 | $193 | $2,316 | $6,948 | $11,580 |
| 10×30 | $256 | $3,072 | $9,216 | $15,360 |
A climate-controlled 10×20 averaging $232 per month reaches $13,920 over 5 years before added charges or price changes.
That’s why the expected rental period matters so much.
A 3-month rental during a move solves a temporary problem. Paying for 2 large units year after year deserves a deeper cost comparison.

Storage costs for homeowners
Homeowners often rent during a move, renovation, downsizing project, or estate cleanout.
A few practical starting points:
- Use a 5×5 for boxes, decorations, and small furniture.
- Use a 5×10 for one bedroom or a modest amount of household overflow.
- Use a 10×10 for a 1- or 2-bedroom move.
- Consider a 10×15 or 10×20 for a larger household renovation.
Pick the smallest unit that fits without forcing you to build an unsafe wall of boxes. A unit packed to the door becomes a black hole. The item you need will always be in the back. That appears to be a law of storage.
For long-term household overflow, compare the accumulated rental bill with the installed cost of on-site storage. Include the foundation, site preparation, permits, insurance, and maintenance in the ownership number.
Storage costs for contractors
Contractors need access as much as square footage.
A cheap indoor unit can slow your crew down when every load requires a cart, elevator, and 200-foot hallway. A drive-up 10×15 or 10×20 may cost more per month but save paid loading time.
Think about:
- Door width and height
- Trailer access
- Vehicle turning space
- Gate hours
- Weekend access
- Electrical outlets
- Camera coverage
- Unit alarms
- Delivery acceptance
- Rules for business inventory
- Weight limits on upper floors
Most facilities allow storage but prohibit running a workshop or operating a business from inside the unit. Hazardous materials, toxic chemicals, perishables, and living items are also commonly prohibited.
Gasoline, propane, paint, fertilizer, pesticides, and similar materials need approved storage elsewhere. Clean and drain permitted equipment before moving it into a unit.
Storage costs for farmers and ranch owners
A rental unit can help with seasonal overflow, parts, hand tools, fencing supplies, boxed records, and equipment that fits through the door.
Distance can erase the savings.
A farmer who needs a part during planting or harvest can’t always afford a 45-minute round trip to town. Frequent-access items usually belong closer to where the work happens.
Check the facility’s rules before storing:
- Tires
- Batteries
- Lubricants
- Animal-health supplies
- Seed
- Feed
- Fertilizer
- Pesticides
- Fuel-powered equipment
Facilities commonly prohibit hazardous chemicals, perishables, and liquids.
Long-term farm storage often deserves an on-site building comparison. Add up the rent on every unit, the travel cost, loading time, and the risk of being locked out after hours. That combined number is more useful than rent alone.
Storage costs for small businesses
Self-storage can work well for boxed inventory, displays, archived files, event supplies, tools, and seasonal merchandise.
Choose the unit around your retrieval pattern.
Inventory that moves every day needs shelving, labels, an aisle, and easy vehicle access. Archived records can sit farther back in a smaller indoor unit.
Ask whether the facility allows:
- Commercial deliveries
- Multiple authorized users
- Package acceptance
- Extended gate access
- Shelving
- Business inventory
- Vehicle storage
- Regular employee access
Sensitive stock may need climate control. Paper records, electronics, wood products, textiles, and items affected by humidity deserve extra care.

When renting makes sense
A storage-unit rental is usually practical when:
- You’re moving and need space for a few months.
- Your home is under renovation.
- You’re settling an estate.
- Your business has temporary excess inventory.
- You need storage in another city.
- You have no suitable land for an on-site building.
- Your storage needs may shrink soon.
The month-to-month model gives you room to leave once the project is finished.
Set an exit date. Review the contents every 3 months. People often keep paying because moving the pile feels harder than paying one more bill.
When on-site storage deserves a price comparison
Long-term renters should calculate what they’re spending across several years.
A contractor renting 2 standard 10×20 units at the 2026 national average would pay about $386 per month, $4,632 per year, or $23,160 over 5 years before fees and increases.
An on-site metal storage building may make financial sense when you:
- Own suitable property
- Need storage for several years
- Rent multiple large units
- Make frequent trips to the facility
- Need wider doors or taller clearance
- Want storage near your home, farm, or business
- Have a growing equipment or inventory load
Use this calculation:
Break-even period in months = total installed building cost ÷ monthly storage rent avoided
The building cost needs to include the full project:
- Building package
- Delivery and installation
- Site preparation
- Foundation or concrete
- Permits
- Electrical work
- Insulation
- Doors
- Financing expense
- Insurance
- Maintenance
Compare like with like. A 10×20 rental unit gives you 200 square feet. A building with the same footprint may provide better door access and control, though it comes with site and ownership costs.
For commercial self-storage development, construction budgeting needs a separate calculation covering land, unit mix, concrete, doors, security, permits, and climate control. Our mini-storage construction cost guide covers those project expenses in detail.

How to spend less on a storage unit
Make an inventory before choosing the size
Write down the large pieces and estimate your box count. Measure bulky items.
Storage sales staff can make a better recommendation when you give them real dimensions rather than saying, “It’s about half a garage.”
Compare the normal monthly price
A $1 first month can still lead to an expensive year.
Compare:
- Amount due today
- Normal monthly rent
- Insurance
- Taxes
- Lock cost
- Administrative charge
- Rate-guarantee period
- Cancellation rules
Ask for a smaller unit after packing
Furniture can often be disassembled. Empty drawers waste space. Matching boxes stack more safely than grocery-store boxes in 14 unrelated shapes.
Use freestanding shelving when the contract permits it. Keep heavy items low.
Skip climate control when the contents can handle it
Climate control earns its cost for sensitive belongings.
Clean metal tools, outdoor furniture, plastic bins, and other temperature-tolerant goods may be suitable for standard storage. Your climate, packaging, and rental period still matter.
Check your existing insurance
Your homeowners, renters, or business policy may cover stored property, though limits and exclusions vary. Ask your insurer for written confirmation before declining a facility plan.
Review the unit every 3 months
Sell, donate, relocate, or discard items that no longer justify their share of the rent.
A $119 unit costs almost $1,430 per year. Keeping $300 worth of unused furniture there for 4 years is expensive furniture storage.
Questions to ask before signing the rental agreement
Take this list with you:
- What is the full monthly cost after the promotion?
- How long is this rate guaranteed?
- How much notice is given before an increase?
- What insurance coverage is required?
- Are there setup, lock, tax, or administrative charges?
- Are move-out months prorated?
- What are the gate and office hours?
- Is drive-up access available?
- Has this unit had water or pest problems?
- What security systems cover this section?
- Can contractors or employees access the unit?
- Are business deliveries allowed?
- Which items are prohibited?
- What happens after a late payment?
- How much notice must I give before moving out?
Walk through the exact unit whenever possible. Confirm that the door works, the roof and walls look dry, and the floor has no sign of standing water.
Frequently asked questions
How much is a storage unit per month in 2026?
The weighted national average was $133 per month in May 2026. Smaller standard units may average $52 to $74, while large units can average $193 to $256 or more. Location and climate control can change the price sharply.
How much does a 10×10 storage unit cost?
A standard 10×10 storage unit averaged $119 per month in early 2026. A climate-controlled 10×10 averaged $134 per month.
What is the cheapest common storage unit size?
A 5×5 is usually the cheapest common size. The national average was about $52 per month for a standard unit and $53 for climate-controlled space at the beginning of 2026.
How much does climate-controlled storage cost?
Climate-controlled prices depend on size. National averages ranged from about $53 per month for a 5×5 to $327 for a 10×30 in January 2026. A climate-controlled 10×10 averaged $134.
How much does a storage unit cost for one year?
At national average rates, a standard 5×10 costs about $888 for one year. A 10×10 costs about $1,428, and a 10×20 costs about $2,316. These totals exclude insurance, taxes, setup charges, locks, and rent increases.
Can a storage facility increase the monthly price?
Yes. Many storage agreements are month to month, and the operator may change the rate after giving the notice required by the contract and local law. Ask how long the move-in rate is guaranteed before signing.
Does the advertised storage price include insurance?
Often, it doesn’t. Some facilities require proof of insurance or enrollment in a tenant-protection plan. Administrative charges, taxes, and locks may also sit outside the advertised rate.
Is it cheaper to rent a storage unit or own a storage building?
Renting usually works well for short-term needs. Long-term renters should compare several years of rent with the complete installed cost of an on-site storage building. Include the building, foundation, site work, permits, financing, insurance, and maintenance.
Can contractors store tools in a storage unit?
Many facilities allow tools and business inventory. Rules vary. Working from inside the unit may be prohibited, and hazardous materials such as fuel, toxic chemicals, and certain liquids are commonly banned.
Rent for the short job. Price ownership for the long one.
Storage units solve real problems. They give you room during a move, renovation, business rush, or family change without requiring a permanent building.
Time changes the math.
A few months of rent can be reasonable. Several years of rent on a large unit can reach $10,000, $15,000, or more. Multiple units raise that total even faster.
Run the numbers using the normal monthly rate, every required fee, your travel time, and the number of years you expect to need the space.
