5. Operating Partnerships [Abstract]
Operating Partnerships [Text Block]	5. Operating Partnerships As of December 31, 2011, Camden Operating, L.P. (“Camden Operating” or the “operating partnership”) had 4.0 million 7.0% Series B Cumulative Redeemable Perpetual Preferred Units outstanding. Distributions on the preferred units were payable quarterly in arrears. In February 2012, we redeemed all of these outstanding units at their redemption price of $25.00 per unit, or an aggregate of $100.0 million, plus accrued and unpaid distributions. In connection with this redemption, the unamortized issuance costs relating to these units of approximately $2.1 million were expensed in the first quarter of 2012. We hold the controlling managing member interest in Oasis Martinique, LLC, which owns one property in Orange County, California and is included in our consolidated financial statements. During the first quarter of 2012, the remaining interests, comprising approximately 0.3 million units, were converted to approximately 0.2 million of our common shares, resulting in this entity being wholly-owned.
