It took place on the same day as many other local elections in Wales and England.
This was the tenth annual all-Cardiff elections since the 1914-18 Great War.
Elections to the local authority were held annually, though not all council seats were included in each contest, because the four councillors in each ward stood down for election in three-yearly rotation.
Following the November 1927 election the balance on the city council was 18 Liberal, 18 Conservative, 13 Labour and 3 Others.
In 1929 Labour increased their number by two, Conservative and Independent dropped by one each.
