STATES IN THE US + Puerto Rico


Rentable Square Feet

NSA is focused on growing through the integration of best-in-class regional operators with self storage properties located in markets with strong fundamentals in the top 100 MSAs throughout the United States. NSA’s differentiated strategy was designed to facilitate outperformance over the long-term.

Innovative Structure

NSA’s PRO structure incentivizes private self storage operators to join NSA thereby facilitating robust portfolio growth, shared operating expenses and the realization of meaningful scale benefits.

Differentiated Market Exposure

Approximately two-thirds of NSA’s properties are located outside of the top 20 MSAs. In the most recent development cycle, new development was largely concentrated in the top MSAs.

Multi-Faceted External Growth Strategy

Since NSA’s IPO in 2015, the Company has grown its portfolio at a rapid pace. The Company has achieved this robust growth through:

  1. Adding new PROs
  2. Captive pipeline acquisitions
  3. Third party acquisitions
  4. Strategic joint ventures

Company History

Arlen Nordhagen co-founded SecurCare Self Storage in 1988 to invest in and manage self storage properties. In 2007, SecurCare raised $100M of institutional capital to expand the platform. Mr. Nordhagen subsequently recognized a market opportunity for a differentiated public self storage REIT that would leverage the benefits of national scale by integrating multiple experienced regional operators with local operational focus and expertise. Mr. Nordhagen’s vision culminated in the formation of NSA in 2013 by three founding PROs (SecurCare, Northwest and Optivest).
