Residential definition

It defines residential purpose groups as:

Residential (dwellings):

A separate and self-contained premises constructed or adapted for use for residential purposes and forming part of a building from some other part of which it is divided horizontally (includes live/work units, i.e. a flat intended to serve as a workplace for its occupants and for persons who do not live on the premises).

Residential (Institutional): Hospital, home, school or other similar establishment used as living accommodation for, or for the treatment, care or maintenance of persons suffering from disabilities due to illness or old age or other physical or mental incapacity, or under the age of 5 years, or place of lawful detention, where such persons sleep on the premises.
