 Approved document B definition
A unit of residential accommodation occupied (whether or not as a sole or main residence):
- By a single person or by people living together as a family.
- By not more than six residents living together as a single household, including a household where care is provided for residents.
A dwellinghouse is regarded as large if it has more than one storey and any of those storeys exceed 200 sq. m.
 Approved document L1A definition
‘...a self-contained unit designed to accommodate a single household.‘
The 2001 Census definition of a dwelling is:
'a self-contained unit of accommodation. Self-containment is where all the rooms (including kitchen, bathroom and toilet) in a household’s accommodation are behind a single door which only that household can use. Non-self contained household spaces at the same address should be counted together as a single dwelling. Therefore a dwelling can consist of one self-contained household space or two or more non-self-contained household spaces at the same address.
'Ancillary dwellings (eg former ‘granny annexes’) are included provided they are self-contained, pay separate council tax from the main residence, do not share access with the main residence (eg a shared hallway) and there are no conditional restrictions on occupancy.'
For more information see: Gov.uk, Definitions of general housing terms.
The English Housing Survey Housing Stock Report, 2014-15, prepared by the Department of Communities and Local Government, defines a dwelling as:
- The household spaces it contains are ‘part of a converted or shared house’, or
- Not all of the rooms (including kitchen, bathroom and toilet, if any) are behind a door that only that household can use, and
- There is at least one other such household space at the same address with which it can be combined to form the shared dwelling.
