Organization, Consolidation and Presentation of Financial Statements [Abstract]  
National Storage Affiliates Trust was organized in the state of Maryland on May 16, 2013 and is a fully integrated, self-administered and self-managed real estate investment trust focused on the self storage sector. As used herein, "NSA," the "Company," "we," "our," and "us" refers to National Storage Affiliates Trust and its consolidated subsidiaries, except where the context indicates otherwise. The Company intends to elect and qualify as a real estate investment trust ("REIT") for U.S. federal income tax purposes commencing with its taxable year ending December 31, 2015.
Through our controlling interest as the sole general partner of NSA OP, LP (our "operating partnership"), a Delaware limited partnership formed on February 13, 2013, we are focused on the ownership, operation, and acquisition of self storage properties in the United States. Pursuant to the Agreement of Limited Partnership (as amended, the "LP Agreement") of our operating partnership, our operating partnership is authorized to issue Class A Units ("OP units"), different series of Class B Units ("subordinated performance units"), and Long-Term Incentive Plan Units ("LTIP units"). We also own certain of our self storage properties through other consolidated limited partnership subsidiaries of our operating partnership, which we refer to as "DownREIT partnerships." The DownREIT partnerships issue equity ownership interests that are intended to be economically equivalent to our OP units ("DownREIT OP units") and subordinated performance units ("DownREIT subordinated performance units").
The Company completed its initial public offering on April 28, 2015, pursuant to which it sold 20,000,000 shares of the Company's common shares of beneficial interest, $0.01 par value per share ("common shares"), at a price of $13.00 per share. As part of the offering, the Company granted the underwriters an option to purchase up to 3,000,000 additional common shares within thirty days after the offering. The underwriters exercised their option and, on May 18, 2015, purchased an additional 3,000,000 common shares. These transactions resulted in net proceeds to the Company of approximately $278.1 million, after deducting the underwriting discount and before additional expenses associated with the offering.
The Company contributed the net proceeds from its initial public offering to our operating partnership in exchange for 23,000,000 OP units. OP Units are the economic equivalent of the Company's common shares and for each common share issued by the Company, our operating partnership issues a corresponding OP Unit to NSA in exchange for the contribution of the proceeds from the share issuances. Immediately prior to the completion of our initial public offering on April 28, 2015, we redeemed 1,000 common shares held by National Storage Affiliates Holdings, LLC ("Holdings"), an entity formed on February 13, 2013, for no consideration. Prior to this redemption, the Company was 100% owned by Holdings and the only assets of Holdings were 126,400 OP units and 1,000 common shares.
The Company owned 261 self storage properties in 16 states with approximately 14.8 million rentable square feet in approximately 115,000 storage units as of September 30, 2015. These properties are managed with local operational focus and expertise by our participating regional operators ("PROs"). These PROs are SecurCare Self Storage, Inc. and its controlled affiliates ("SecurCare"), Kevin Howard Real Estate Inc., d/b/a Northwest Self Storage and its controlled affiliates ("Northwest"), Optivest Properties LLC and its controlled affiliates ("Optivest"), Guardian Storage Centers LLC and its controlled affiliates ("Guardian"), Move It Self Storage and its controlled affiliates ("Move It"), and Arizona Mini Storage Management Company d/b/a Storage Solutions and its controlled affiliates ("Storage Solutions").
