The district was formed by the Local Government Act 1894 from the area of the existing St Albans rural sanitary district. An elected rural district council replaced the rural sanitary authority which had consisted of the poor law guardians of the area. The rural district comprised an area surrounding the Borough of St Albans, but did not include the city, which was an independent municipal borough.
The rural district initially consisted of seven civil parishes. Three parishes were formed in 1894 by the division of the parishes of St Michael, St Peter and Sandridge between the rural district and the city of St Albans. In 1947 the number was increased to eight, with the division of the parish of St Peter Rural.
