Questions about house to HMO conversion in Richmond

It depends on the nation, the council and the number of sharers. In England, three to six unrelated sharers is use class C4, and moving from a family house is usually permitted development unless the council has an Article 4 direction; seven or more normally needs permission. In Wales a change to an HMO always needs permission, in Northern Ireland all new HMOs need it, and in Scotland council policy decides. We check the address before drawings start.
