self storage units

For people in need of extra space for their belongings, storage companies offer the opportunity to stow a wide array of items in a rental unit.

The units vary significantly — from indoor units as small as 5 feet by 5 feet capable of storing a few odds and ends, to large outdoor garage spaces that can accommodate vehicles or commercial storage needs.

Some facilities come with special characteristics, such as advanced security measures like individually alarmed units, or climate-controlled storage to protect temperature-sensitive items.

General storage unit statistics

With widespread use of storage units in the U.S., self-storage facilities are resilient to economic shocks, with the usage of units often closely tied to the housing market and moving residences.

For example, self storage benefited during the COVID-19 pandemic, because of the increase in people relocating and the growth of  home offices. In a strong economy, consumers often accumulate more material goods, opting to keep some of these possessions in storage units — in a weaker economy, consumers and businesses may turn to storage units when downsizing.

The evidence of the industry’s strength was seen throughout and after the pandemic. Private construction spending on mini-storage facilities annually grew from about $4.6 billion from 2019 to 2020, to a record high of nearly $7 billion in 2023.

The market is composed of several different types of units, including the following:

  • Outdoor units: These garage-like facilities are typically more spacious and can be reached by driving directly up to the unit. However, they are more susceptible to security issues and tend to be a bit cheaper than other options.
  • Portable units: These units, often called pods or moving containers, can provide space when moving a long distance or for temporary storage. These units are typically delivered and picked up by a company that can transport them to a new location.
  • Climate-controlled units: A more expensive option, climate-controlled storage offers specialized spaces with temperatures between 55 and 85 degrees. These are meant for storing items sensitive to extreme temperatures.

Storage unit industry market size

In 2024, the estimated size of the global self-storage market is more than $58 billion.

The self-storage market is expected to grow to more than $72 billion by 2029, as a combination of increasing urbanization and economic growth driving new business.

Personal storage makes up a major share of the market, as businesses also rely on larger storage facilities such as warehouses, in place of self-storage units.

Market size by region

The self-storage market is most prominent in North America, where in recent years, the U.S. has seen continued growth.

In 2022, U.S. self-storage businesses recorded nearly $20 billion in revenue, a 16% increase over 2021 and a 55% increase from 2017.

North America is expected to continue to be the largest segment of the self-storage market, as storage units remain more widely available in the urbanized U.S. and Western Europe. The industry is still getting off the ground in new markets, such as China and India.

The major players in the self-storage industry are U.S.-based companies, such as Public Storage, Extra Space Storage and CubeSmart.

Storage unit costs and factors

Per-month costs for storage units typically range from $90 to $290 and include an upfront administrative fee and monthly rental payment. These costs vary depending on the size of the rented unit and any other add-ons, such as a climate-controlled space.

The most common storage unit, 10 feet by 10 feet, can hold the furniture from a single room and has an average monthly cost of $160.

Alongside unit size, other factors that may affect the cost of a storage unit are as follows:

  • Security: Some facilities have secure entrances and exits with guards, cameras, or a keypad. These upgrades generally come with higher costs and may be a better option for storing more costly items.
  • Location: Similar to rent, fees are typically more expensive for units in larger urban areas.
  • Season: Fees fluctuate depending on the time of year and may cost more during peak times, such as the summer when students store items between semesters.
  • Length of rental: Shorter rental periods may come with higher monthly fees, as many companies offer discounts for long-term rentals or contracts.
  • Additional fees: Some facilities also charge for insurance protection or security deposits.

Storage unit usage

In the U.S., storage-unit occupancy rates have hit record highs in recent years, peaking around 92% in 2021 and 2022, before a recent downturn in 2023. In September 2023, estimates indicated that occupancy of U.S. storage units had fallen to 87%.

With fewer relocations, the drop came alongside a downturn in the housing market, and residents relying on storage units to hold extra belongings.

In Europe, the average occupancy rate of storage units was nearly 79% in 2023, reflecting lower usage of self storage than in the U.S.

Storage unit industry future projections

The global market for the self-storage industry is expected to grow at a compound annual rate of 4.4% over the next five years, increasing to an annual revenue of more than $72 billion by 2029.

Factors driving the growth include increasing urbanization and rising urban populations more likely to rely on self-storage facilities, located in urban and suburban areas. The growth of e-commerce is also a contributing factor, as more online businesses turn to self storage as a cost-effective means to store inventory.

Other projections for the U.S.-based self-storage industry indicate an expansion of supply in the short term, while the development of new storage facilities will decline in the long term.
