The district council's headquarters were at Lugar, near Cumnock.
The district was abolished in 1996 by the Local Government etc. (Scotland) Act 1994, when the regions and districts were replaced by unitary council areas. The area of Cumnock and Doon Valley District was merged with that of Kilmarnock and Loudoun to form East Ayrshire.
Because of the fairly short and modern existence of this district, no material of genealogical interest has been attached to it. Refer to Ayrshire and the parishes within it.
