It says mayors will also have a greater say over national housing funding in their areas, while Homes England would focus its funding and expertise around priorities agreed with mayors. Proposals also include powers to permission in advance in designated circumstances and to raise a development levy for major .

The detailed proposals are due to be published by government, so the precise way the powers will operate in practice will matter. For now, the change is that some of the biggest planning decisions in the Tees Valley could ultimately move from individual councils to the mayoral level.
