Clause A3—Building importance levels For the purposes of clause C, a building has one of the importance levels set out below: Importance level Importance level 1 Specific structure • Ancillary buildings not for human habitation • Minor storage facilities • Backcountry huts Importance level 2 Importance level 3 Description of building type 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.

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.

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.
• All buildings and facilities except those listed in importance levels 1, 3, 4, and 5 • • • 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 23 Schedule 1 Building Regulations 1992 Version as at 24 August 2023 Importance level Description of building type Specific structure • 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.
24 • • • • 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 • • • Version as at 24 August 2023 Building Regulations 1992 Schedule 1 Importance level Description of building type 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).
Specific structure • 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 • Major dams • Extremely hazardous facilities Schedule 1 clause A3: inserted, on 10 April 2012, by regulation 5 of the Building (Building Code: Fire Safety and Signs) Amendment Regulations 2012 (SR 2012/33).
