New York City Leads U.S. in Self-Storage Conversions

Over the last decade, New York City has emerged as the U.S. leader in converting industrial, commercial, and retail spaces into self-storage facilities. According to a new report from StorageCafe, these conversions have reshaped the urban landscape, tapping into an abundance of unused properties while catering to the city's ongoing need for storage space. But with this trend also comes an interesting mix of real estate implications, from shifting property values to the dynamics of rental prices.

The Adaptive Reuse Boom: Self-Storage Takes Over Industrial Spaces

New York City, with its deep industrial roots and rich history as a major shipping hub, offers a unique opportunity for repurposing older buildings. From outmoded factories and warehouses to vacant commercial properties, NYC has a surplus of underutilized real estate that can be repurposed for self-storage. The city’s conversion trend is part of a larger movement toward adaptive reuse in urban areas, where developers are finding creative ways to breathe new life into buildings that no longer serve their original purposes.

Brooklyn: The Nation’s Self-Storage Conversion Leader

Of the five boroughs, Brooklyn stands out as the leader in self-storage conversions. Over the past decade, more than 4.6 million square feet of industrial and retail space have been transformed into storage units across 42 properties. This accounts for over half of Brooklyn’s total 8.9 million square feet of self-storage, cementing the borough’s status as a self-storage powerhouse.

In fact, Brooklyn is second in the nation—just behind Chicago—when it comes to the amount of space converted for storage use. While Chicago has 72 properties totaling 7.2 million square feet, Brooklyn's numbers reflect the borough's growing role in the self-storage market, which has become a key part of the city's real estate landscape.

Manhattan: High Demand and Skyrocketing Prices

Manhattan follows closely behind Brooklyn in the self-storage conversion race, with 37 facilities and a total of 4.4 million square feet of converted storage space. However, Manhattan faces a much different dynamic when it comes to storage availability and pricing.

Despite the large number of conversions, the city remains severely undersupplied in terms of per capita self-storage space. In fact, Manhattan has just one square foot of self-storage space for every person, leading to a highly competitive market. The limited supply has pushed prices up considerably, with the average monthly cost of a standard unit hitting $241—well above the national average of $136.

For real estate professionals, this high demand and limited supply make Manhattan’s self-storage properties a lucrative but costly investment. The price premium for storage in Manhattan reflects broader trends in the city's commercial real estate market, where space is at a premium and competition is fierce.

Queens: Conversions Meet Cost Advantage

Queens, often regarded as the “World’s Borough,” is another hotspot for self-storage conversions. With 15 converted facilities totaling 1.4 million square feet, Queens has seen a significant uptick in repurposed properties. However, unlike Manhattan, where conversions are driving up prices, the cost of converted storage in Queens remains much more affordable.

Converted facilities in Queens charge an average of $5 per square foot, compared to $37 per square foot for purpose-built self-storage buildings. This price gap creates a clear incentive for consumers and businesses to seek out converted facilities, driving growth in this part of the self-storage market. For real estate developers, this could signal an opportunity to capitalize on the affordability and growing demand for converted self-storage units in Queens.

The Bronx: A Rising Player in Self-Storage

The Bronx, though not as heavily converted as Brooklyn or Manhattan, ranks third among the NYC boroughs and fifth nationally in self-storage space, with 21 converted facilities adding up to 2.1 million square feet of storage space. In the Bronx, conversions make up about one-third of the total storage properties, which is a significant portion when compared to other boroughs.

Perhaps one of the most compelling trends in the Bronx is the price advantage. Converted facilities in the Bronx charge $6 per square foot, which is roughly four times cheaper than purpose-built self-storage properties, where the cost is $24 per square foot. This cost difference translates to lower rent for consumers—around $165 for converted units versus $199 for purpose-built storage. The affordability factor in the Bronx makes it a desirable market for both storage users and investors looking to tap into a more cost-effective segment of the self-storage industry.

Real Estate Implications: A Growing Niche Market

‍

The rising trend of converting industrial and retail spaces into self-storage facilities reflects larger shifts in urban real estate. As cities like New York continue to grapple with space shortages, creative adaptive reuse projects offer a win-win scenario: they revitalize underutilized properties while meeting the rising demand for affordable storage options.

For real estate professionals, this trend offers several key takeaways:

1. Investment Opportunities in Adaptive Reuse: Converting existing buildings into self-storage facilities offers developers an opportunity to repurpose older, obsolete buildings while capitalizing on an increasing demand for storage space. In boroughs like Brooklyn and Queens, where demand continues to outpace supply, these conversions present a relatively low-risk investment, particularly in areas where land is scarce and new developments are expensive.
2. Renting and Property Values: The rise of self-storage facilities has potential implications for the broader real estate market, especially in areas where these facilities are concentrated. As rental prices for storage units continue to climb, landlords of commercial properties may look to pivot and convert their unused space into storage units—potentially boosting returns on underperforming assets.
3. Price Sensitivity and Consumer Behavior: As the self-storage market becomes more competitive, particularly in Manhattan, consumers will likely seek out more affordable options in areas like the Bronx and Queens. Developers can take advantage of this trend by offering lower-cost converted facilities, which could attract a wider range of renters and small businesses looking for cheaper storage options.
4. Urban Redevelopment and Neighborhood Transformation: The conversion of industrial spaces into self-storage units is also a sign of broader urban transformation. These projects help revitalize neighborhoods that were once dominated by warehouses and factories, turning them into vibrant hubs for modern-day needs. As these facilities continue to pop up, it will be interesting to see how they influence local property values and gentrification trends.
