If you live in a densely populated urban area, you know that having a little elbow room comes with a big price tag. You’ve probably calculated the cost per square foot over and over while searching for an apartment or house. And “do I really need a bedroom?” becomes a real debate. Self-storage is a luxury for those living in cities that are home to some of the most expensive property prices in the world. Couple that with the massive growth of urbanization in countries like China and South Africa, and the price per square foot (or meter!) really skyrockets.

By the end of this decade, over 50% of the world's population will live in major cities. And just like real estate, selling self-storage is a lucrative business in these major metropolitan areas. I did some investigating and found the 20 most expensive places in the world to rent a standard 5 x 10 ft. storage unit, based on average cost per month. All of the prices have been converted to USD for a true comparison. Check out my list of the most expensive cities in the world to rent a storage unit!

With 2.2 million residents and hundreds of historic areas, Paris is extremely limited on living space. Students flock to Paris for their world-class universities and celebrities buy up real estate.

The Golden Gate Bridge in San Francisco Bay.

11. San Francisco: $166/mo

Party in the city where the heat is on...for self-storage, that is. Miami is home to many of the world's wealthiest residents. Of course, with riches comes a need for high-security storage.

6. Dubai: $192/mo

The business hub of the Middle East and jewel of the Persian Gulf is home to 2.5 million people, and one out of every 100 people in Dubai is a millionaire. Of course, millionaires need somewhere to store their toys, too. Uber-secure (and highly expensive) self-storage is common in Dubai. Many facilities don't even list their location on their website for added security. You can expect to pay as much as $231 per month for a 5 x 10 ft unit in Dubai.

5. Hong Kong: $205/mo

Space is incredibly expensive in Hong Kong, the world's fourth most densely populated state. The city is also exorbitantly wealthy: Hong Kong has more Rolls Royce cars per capita than anywhere else in the world. Self-storage is popular among those who can afford it. Micro storage units (think your middle school locker) are just as common here as more standard American size units. A 5 x 10 ft storage unit ranges from $103 to $377 per month.

3. Shanghai: $217/mo

With 14.3 million residents, Shanghai is the most densely populated city in China. Housing costs are also six times higher than anywhere else in China, so ample living space is a luxury reserved for the wealthy. Self-storage is huge for those moving to the city. Love Box Self Storage is a popular choice created by expats to help with the transition. But space is expensive, with units starting around $165 per month and topping out around $300.

2. New York: $219/mo

The Big Apple is home to 8.5 million people, and it’s also the most expensive place in America to rent a storage unit. But that shouldn't come as a huge surprise. Everything is more expensive in New York, especially when you're talking about square footage. Rent prices have skyrocketed due to a shortage of affordable housing and few areas available for new development. Storage units feel like a steal compared to the cost of housing. Unit prices range from around $100 per month in the Brooklyn area to $350 per month in the Chelsea neighborhood.

1. Tokyo: $280/mo

The world’s biggest city is also the most expensive place in the world to rent a storage unit. Tokyo's 13 million residents do self-storage a little differently. Units are typically referred to as "trunk rooms" and sizes are measured by the number of tatami mats that can fit in the space. A 5 x 10 ft unit (or 2.8 tatami) in Tokyo is considered a large unit, and they’re much harder to come by than locker size micro-units. Only the affluent can afford large units in Tokyo. Japan's 1% are more likely to store artwork or nihonshu than sports cars or expensive jewelry, so extra-large units are typically high-security units reserved for millionaire expats. The cheapest 5 x 10 ft unit I could find cost 21,300 yen, which translates to $211 USD at the current exchange rate. Units nearby more exclusive neighborhoods like Ebisu and Azabu were around 50,000 - 58,000 yen per month, or $495 - $574 USD.
