Both events take place from Aug. 11-17 and Roddick wants to remain in his home country to help his build-up for the US Open which begins two weeks later.
"My goal every summer is to win the US Open," the 25-year-old American said in a statement released on Tuesday by Washington Open organisers.
"I have won the Legg Mason Tennis Classic three times and feel defending my title in Washington best prepares me for another grand slam title."
Roddick, who won his only grand slam title at the 2003 US Open, triumphed in Washington in 2001, 2005 and last year.
He clinched the 2007 crown by beating fellow American John Isner 6-4, 7-6 in the final.
