  ITEM 8.01 OTHER EVENTS
  On
  May 13, 2008, Extra Space Storage Inc., or the Company, entered into an
  underwriting agreement with Merrill Lynch, Pierce, Fenner & Smith
  Incorporated and Citigroup Global Markets Inc., pursuant to which the Company
  agreed to issue and sell 13,000,000 shares of the Company's common stock, par
  value $.01 per share, or the Common Stock, plus up to an additional 1,950,000
  shares of Common Stock pursuant to the Underwriters' over-allotment option, at
  a price to the public of $16.35 per share. The Underwriters exercised their
  over-allotment option in full on May 16, 2008. The offering (including the
  shares sold pursuant to the Underwriters' over-allotment option) is expected to
  close on May 19, 2008. Gross proceeds from the offering (including the
  shares sold pursuant to the Underwriters' over-allotment option) are expected
  to be approximately $233,433,038.
  Kenneth
  M. Woolley, the Company's Chairman and Chief Executive Officer, and Spencer F.
  Kirk, the Company's President, are each purchasing 60,000 shares of Common
  Stock in the offering at the public offering price.
  The
  Company intends to use approximately $55.5 million of the net proceeds of this
  offering to repay mortgage debt and outstanding amounts under its secured line
