Seven years later, in 1447, the county corporate was extended to also include an adjoining rural area lying to the west of Hull itself, which became known as Hullshire.

[10] The reformed borough was enlarged to match the Kingston upon Hull constituency, which had been expanded in 1832 to take in areas including Drypool and Sculcoates.

[11] As part of the same reforms, Hull lost its jurisdiction over the parts of Hullshire outside the enlarged borough boundary (the parishes of Hessle, Kirk Ella and North Ferriby and their associated townships), which were returned to the jurisdiction of the Sheriff of Yorkshire.

[16] Hull's borough and city statuses and its lord mayoralty were all transferred to the new district and its council.

This therefore had the effect of restoring the city council to the powers it had held when Hull was a county borough prior to 1974.

Political control of the council since 1929 has been as follows:[27] The role of Lord Mayor is largely ceremonial.

[39] The council meets at the Guildhall at the junction of Alfred Gelder Street and Lowgate in the city centre.

[41] It has several other administrative buildings, including the Wilson Centre, also on Alfred Gelder Street (which houses the main customer service centre),[42] and the City Treasury building on Guildhall Road, immediately north of the Guildhall.
