Guest side Malawi and Djibouti are the other teams in Group C, Tanzania and Somalia feature in Group A while Burundi and Zanzibar complete Group B.
As well as Addis, games are set to be played in Hawassa and Bahir Dar.
One side that is not taking part is Eritrea with Nicholas Musonye, the Cecafa secretary general, explaining this was due to their ongoing political tensions with hosts Ethiopia.
Eritrean players have also sought political asylum on several trips to play overseas. most recently for a World Cup qualifier in Botswana.
Kenya's Harambee Stars won the last tournament on home soil in 2013 with a win over Sudan in the final.
The regional tournament was not held last year after Ethiopia withdrew from hosting the event.
