Storage unit prices can vary widely, even within the same market. There are many factors that contribute to the prices offered by any given storage location.

The good news for consumers is that the cost to rent a self-storage unit has gone down in recent years thanks to a surge of new storage facilities opening up around the country.

How Much Does a Storage Unit Cost?

The average monthly cost to rent a self-storage unit is $89.12. That is the average monthly rental price for reservations on all storage sizes and types made on SpareFoot’s self-storage network over the last 12 months.

That is a 1.39% increase from the average price in 2019, which equaled $87.89 per month. The coronavirus pandemic and associated response contributed to increased demand for self-storage space in 2020, causing prices to rise slightly from the previous year. Record levels of self-storage development in the years proceeding the pandemic have provided an ample amount of supply in many markets, which has prevented prices from rising too quickly. In some markets with limited supply, rates have increased more dramatically in 2020.

Storage rates per square foot equaled 91 cents on average in 2020.  In 2019, the average price was 92 cents per square foot of self-storage space.

Storage Prices by Unit Size

The price of storage varies by the size of the unit. Usually larger units are more expensive to rent than smaller units. However, the self storage cost per square foot goes down as you move up in size due to economies of scale. Local demand and availability for certain sizes in a market or at a single facility can also affect the price.

The table below shows the average cost for the six most popular storage unit sizes. As you can see some types of units fell in price while others increased in price. This is likely due to variations in market demand.

A major factor in falling prices has been a surge of new storage construction across the country. As the supply of storage units rises to meet demand, prices in many markets are on a downward trend. In other words, storage operators are lowering prices because there is more competition now than there has been in recent years.

Factors Affecting the Cost of Self-Storage

Keep in mind that the average prices above include both climate-controlled and units without climate control. Climate-controlled storage units are generally about 30 to 50 percent more expensive than units without climate control.

There are several other factors that can affect the price of storage units, even within the same market. For example a facility in a rural area will typically be cheaper than a facility in an urban area. When shopping for a storage unit, it is important to consider these additional factors.

Climate Control

Climate control offers better protection for your stored items, as it regulates air temperature and humidity all year-round. Because of the additional costs required to install, maintain and power these systems, you can expect to pay a premium to rent a climate-controlled storage unit.

You can save money by renting a unit without climate-control, however your items will be susceptible to extreme temperatures and high-humidity. This may be fine for the short term storage of durable items, but climate control is strongly recommended when storing valuable and delicate items for long periods of time.


You can expect to pay more for a storage unit from May to September than you would during the rest of the year. During these months is when most Americans move to new homes, which is a major driver for the storage industry. With the increased demand, storage operators are able to increase prices on their storage inventory. Renting a storage unit during the off-season can save you more money than renting during the peak season.

Storage Sizes

Perhaps the greatest determinant of self-storage costs is the size of the unit. Smaller units naturally cost less than larger units. However, larger units should cost less per square foot than a smaller unit.

To find the price per square foot, multiply the size of the unit (10×10=100) to find the total square footage. Then divide your monthly rent by the total square footage. This yields the price per square foot, and can be useful way to make sure you aren’t being charged more than you should for a larger-sized units.

Special Storage Offers

Promotions and specials are very common in the storage industry. Some companies offer first month free deals, for example. When shopping for a storage unit, these promos should be factored into the overall price of a storage unit. Be sure to read the fine print, however, to see if there is a minimum commitment required.

Other times facilities will offer discounts to professional organizations and club members, so always be sure to ask. For example, AAA members can get one month free and get a $20 gift card when they reserve a unit through SpareFoot.

Insurance Coverage Cost

It is important to remember that insurance is not included with the price of storage. Most storage facilities require that your items are insured, and some may ask for proof of insurance. Often times your homeowners or renters policy will cover your items, but not always. You can typically purchase storage coverage from the facility you are renting from.

Generally speaking, $2,000 of coverage will cost around $10 to $12 a month. Policies can go up to around $30 a month and provide up to $5,000 worth of insurance coverage.

Facility Type and Location

Another major factor in pricing is the type and location of the storage facility. A facility in a dense urban area will cost more than a facility in a rural area, as there is more consumer demand inside cities and suburban centers.

The type of facility will also affect cost. Age and condition of a facility could also be a factor. Newer, multi-story indoor facilities typically will command a higher price than an older outdoor facility with drive up access.

In addition to climate-control, other amenities can add to the monthly cost of renting a storage unit. For example, a facility with extensive video cameras throughout the property might charge more than a similar facility without video monitoring. Depending on the market, you might also pay a bit more for 24-hour access.

There has been a recent trend towards unmanned facilities that use a kiosk system to handle rentals. These may cost slightly less to rent from than facilities with an onsite manager, as there is less overhead in the form of employee wages.

Other Facility Charges

Depending on where you live, there might be local taxes applied to your monthly storage rent. Also, some facilities might charge a small administration fee on top of the quoted monthly cost.

Full Service Storage vs Traditional Storage

Recently there has been a new storage concept available in some cities called full service storage. Also known as on-demand or valet storage, these new providers advertise that they offer a more convenient option than traditional mini storage. Full service storage companies will pickup your items from your home and place them in a shared warehouse with other customers’ stuff. When you are ready to receive your items, the company will deliver them to your home.

These companies try to price their services to be comparable to the cost of traditional self-storage. However, there is sometimes a delivery fee and a minimum commitment required.

Popular traditional self-storage companies include Public Storage, U-Haul, CubeSmart, Life Storage and Extra Space. However the majority of self-storage facilities are operated by small and medium sized operators.

Average Cost by Location

If you are searching for “storage units near me“, prices will vary widely depending on where you live in the United States. One major factor is the square foot of self-storage per capita available in a market. The lower amount of square footage available per capita, the higher prices you can expect to find. In other words, storage is more expensive in dense urban areas compared to rural and suburban locations.
