Commercial properties can make ideal conversions into HMOs as often they are situated in or around a town or city centre, have large rooms and services already provided. It is still possible to acquire permitted development rights for changing a commercial property from B1(a) offices to C3 residential (which includes HMOs for no more than 6 people). The permitted development rights will only cover change of use: any associated physical development which currently requires a planning application will continue to need one.
