Your property may be deemed a House in Multiple Occupation (HMO) if it is occupied by multiple tenants who aren’t in the same family. To qualify for this, the property must have a minimum of three tenants or forms more than one household. It could also be an HMO if there are shared facilities, such as a toilet, bathroom or kitchen.
You may require an HMO license, although this depends on the type of property you have. Your local authority will be able to advise you further on this.
