A house to HMO conversion turns a single-family home into a house in multiple occupation: a shared home for unrelated people with private bedrooms and shared kitchen or bathroom space. Birmingham is in West Midlands. We price house to HMO conversion there against England’s HMO rules and the council’s written HMO standards, so work is planned to the standard an inspection looks for. With students as well as working sharers renting in Birmingham, we plan bigger jobs for the gap between academic-year tenancies where we can.

Questions about house to HMO conversion in Birmingham
Do I need planning permission to turn a house into an HMO?
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.
