US Self Storage Market

According to a report by Mordor Intelligence, the US self storage market is expected to reach $44.33 billion in 2024. The market is estimated to grow at a compound annual growth rate (CAGR) of 2.44% and reach $50.01 billion by 2029. The growth can be attributed to the increase in urbanization in the country. Populous states such as Texas, California, Florida, and New York often have smaller living spaces, leading to a high demand for self-storage solutions. The US has also observed an increase in the number of renters, which as a result is driving the demand for self storage facilities in the country. The report cites the data from the US Census Bureau, which states that the number of households living in rented homes in the US reached 43.8 million in 2023, compared to 43.1 million in 2022. Homeownership in the country saw a decline, with only 66% of households owning homes in 2023. For households in rented homes, it becomes challenging to move their belongings to their rental homes, which increases their reliance on self storage units.
