Building Regulations 1992

Clause A1—Classified Uses

1.0 Explanation

• 1.0.1 For the purposes of this building code buildings are classified according to type, under seven categories.

  1.0.2 A building with a given classified use may have one or more intended uses as defined in the Act.

2.0 Housing

• 2.0.1  Applies to buildings or use where there is self care and service (internal management). There are three types:

  2.0.2 Detached dwellings

  Applies to a building or use where a group of people live as a single household or family. Examples: a holiday cottage, boarding house accommodating fewer than 6 people, dwelling or hut.

  2.0.3 Multi-unit dwelling

  Applies to a building or use which contains more than one separate household or family. Examples: an attached dwelling, flat or multi-unit apartment.

  2.0.4 Group dwelling

  Applies to a building or use where groups of people live as one large extended family. Examples: within a commune or marae.

3.0 Communal residential

• 3.0.1 Applies to buildings or use where assistance or care is extended to the principal users. There are two types:

  3.0.2 Community service

  Applies to a residential building or use where limited assistance or care is extended to the principal users. Examples: a boarding house, hall of residence, holiday cabin, backcountry hut, hostel, hotel, motel, nurse's home, retirement village, time-share accommodation, a work camp, or camping ground.

  3.0.3 Community care

  Applies to a residential building or use where a large degree of assistance or care is extended to the principal users. There are two types:

  • (a) Unrestrained; where the principal users are free to come and go. Examples: a hospital, an old people's home or a health camp.

  • (b) Restrained; where the principal users are legally or physically constrained in their movements. Examples: a borstal or drug rehabilitation centre, an old people's home where substantial care is extended, a prison or hospital.

  Schedule 1 clause A1 3.0.2: amended, on 31 October 2008, by regulation 4 of the Building (Building Code: Backcountry Huts) Amendment Regulations 2008 (SR 2008/358).

4.0 Communal non-residential

• 4.0.1 Applies to a building or use being a meeting place for people where care and service is provided by people other than the principal users. There are two types:

  4.0.2 Assembly service

  Applies to a building or use where limited care and service is provided. Examples: a church, cinema, clubroom, hall, museum, public swimming pool, stadium, theatre, or whare runanga (the assembly house).

  4.0.3 Assembly care

  Applies to a building or use where a large degree of care and service is provided. Examples: an early childhood education and care centre, college, day care institution, centre for handicapped persons, kindergarten, school or university.

  Schedule 1 clause A1 4.0.3: amended, on 1 December 2008, by section 60(2) of the Education Amendment Act 2006 (2006 No 19).

5.0 Commercial

• For the purposes of clause C, a building has one of the importance levels set out below:

  Importance level		Description of building type		Specific structure
  Importance level 1		Buildings posing low risk to human life or the environment, or a low economic cost, should the building fail. These are typically small non-habitable buildings, such as sheds, barns, and the like, that are not normally occupied, though they may have occupants from time to time.		•	Ancillary buildings not for human habitation
  				•	Minor storage facilities
  				•	Backcountry huts
  Importance level 2		Buildings posing normal risk to human life or the environment, or a normal economic cost, should the building fail. These are typical residential, commercial, and industrial buildings.		•	All buildings and facilities except those listed in importance levels 1, 3, 4, and 5
  Importance level 3		Buildings of a higher level of societal benefit or importance, or with higher levels of risk-significant factors to building occupants. These buildings have increased performance requirements because they may house large numbers of people, vulnerable populations, or occupants with other risk factors, or fulfil a role of increased importance to the local community or to society in general.		•	Buildings where more than 300 people congregate in 1 area
  				•	Buildings with primary school, secondary school, or daycare facilities with a capacity greater than 250
  				•	Buildings with tertiary or adult education facilities with a capacity greater than 500
  				•	Health care facilities with a capacity of 50 or more residents but not having surgery or emergency treatment facilities
  				•	Jails and detention facilities
  				•	Any other building with a capacity of 5 000 or more people
  				•	Buildings for power generating facilities, water treatment for potable water, wastewater treatment facilities, and other public utilities facilities not included in importance level 4
  				•	Buildings not included in importance level 4 or 5 containing sufficient quantities of highly toxic gas or explosive materials capable of causing acutely hazardous conditions that do not extend beyond property boundaries
  Importance level 4		Buildings that are essential to post-disaster recovery or associated with hazardous facilities.		•	Hospitals and other health care facilities having surgery or emergency treatment facilities
  				•	Fire, rescue, and police stations and emergency vehicle garages
  				•	Buildings intended to be used as emergency shelters
  				•	Buildings intended by the owner to contribute to emergency preparedness, or to be used for communication, and operation centres in an emergency, and other facilities required for emergency response
  				•	Power generating stations and other utilities required as emergency backup facilities for importance level 3 structures
  				•	Buildings housing highly toxic gas or explosive materials capable of causing acutely hazardous conditions that extend beyond property boundaries
  				•	Aviation control towers, air traffic control centres, and emergency aircraft hangars
  				•	Buildings having critical national defence functions
  				•	Water treatment facilities required to maintain water pressure for fire suppression
  				•	Ancillary buildings (including, but not limited to, communication towers, fuel storage tanks or other structures housing or supporting water or other fire suppression material or equipment) required for operation of importance level 4 structures during an emergency
  Importance level 5		Buildings whose failure poses catastrophic risk to a large area (eg, 100 km2) or a large number of people (eg, 100 000).		•	Major dams
  				•	Extremely hazardous facilities
