A semi-commercial property is a property that has both a commercial element and a residential element to it. For example, shops which have flats or living space above them are one of the most common forms of semi-commercial property, but B&Bs, pubs or any business that would require employees to have accommodation on site, such as a kennel service, would qualify for this definition.
Existing rules state that if the residential aspect of a semi-commercial property occupies any more than 40% of the overall floorspace (as well as being occupied by a common tenant) then loans will be regulated.
