In Q2 2025, StorageMart and Manhattan Mini Storage significantly expanded their Third-Party Management portfolio with the onboarding of 31 storage facilities across the United States. This strategic growth adds more than 2.4 million net rentable square feet and over 25,000 storage units to the third-party management footprint, reinforcing its position as a leading provider of third-party management services in the self-storage industry.
Strategic Growth Across New and Existing Markets
These facilities span key suburban and urban areas, including San Antonio, TX; Des Moines, IA; Miami, FL; Pearl River, NY, and 27 former Metro Self Storage locations in high-demand states such as Florida, Illinois, Minnesota, New Jersey, Pennsylvania, and Wisconsin. All locations are currently operating under the StorageMart or Manhattan Mini Storage, depending on regional alignment.
“This kind of nationwide growth under our Third Party Management program reflects the confidence property owners have in our ability to deliver results,” said Alex Burnam, Senior Vice President of Real Estate Acquisitions at StorageMart. “By combining local facility strengths with our operational and marketing expertise, we’re helping owners unlock the full potential of their assets.”
All 31 facilities were existing operations that have now joined the company’s management program. With conveniently placed locations, modern amenities, and StorageMart’s centralized operational support, they are now better positioned to meet the evolving needs of today’s storage customers.
