Concessions to specific Deemed-to-Satisfy Provisions apply to farm buildings and farm sheds in recognition of their often low risk features, and it is recommended that reference is made to the definitions of "farm building" and "farm shed" for further guidance which may assist determination of an appropriate NCC classification. It is expected that this approach may be taken by a builder who is uncertain of what the precise use of a building will be after its sale, or to maximise the flexibility of the building's use.

However, a building could be a mixture of Class 3 and another Class. Regarding A6.9(2) Exemption 1, a building could be a mixture of Class 9b and another Class, or a Class 9b building could contain parts that are of another Class, but be taken as a Class 9b building because of A6.0 Exemption 1.

There is no requirement for Class 10 buildings to be appurtenant to a building of any other Class, for example, a small shed standing on its own on an allotment and a toilet block in a park. The guidance above outlines the relevant Deemed-to-Satisfy (DtS) provisions outlined in NCC 2019 for the fire sprinkler system in any applicable building containing Class 2 and 3 parts. The reason is that laboratories are considered to have a high fire hazard potential and classifying them with the remainder of the building could, in a majority of cases, endanger occupants of the other parts of the building which have a lower fire hazard potential. However, a Class 4 part of a building can only be part of a Class 5-9 building. These kinds of rooms do not need to be ancillary or subordinate to the part of the building they are in, that is, the 10% criterion is not applicable.

Similarly if a Class 7 or 8 building used for farming purposes does not meet all the criteria to be considered a farm building or farm shed under the Deemed-to-Satisfy Provisions, this would not limit the ability to develop a Performance Solution which could contain features similar to those allowed under the Deemed-to-Satisfy Provisions for farm buildings or farm sheds. Apart from their use, the primary difference between Class 1a and Class 1b buildings is that the latter is required to have a greater number of smoke alarms and in some circumstances, access and features for people with a disability. It is also recognised that the specific care needs of the residents may result in a greater minimum number of staff.

For example, if a Class 8 commercial poultry building meets all the criteria to be considered a farm building under the Deemed-to-Satisfy Provisions other than the maximum floor area criteria, a Performance Solution could be developed to demonstrate that the concessions for a farm building under the Deemed-to-Satisfy Provisions are appropriate. Depending upon whether the criteria in the definition of farm shed or farm building have been met, the associated Deemed-to-Satisfy Provisions in NCC Volume One Part H3 may apply. The maximum slope of the floor of 1 in 8 is consistent with . The maximum gap of 125 mm stipulated in is consistent with .

Class 3 buildings, where the occupants are generally unfamiliar with the building and have minimum control over the safety of the building, represent a higher risk level and therefore require higher safety levels. A single Class 1 dwelling can be made up of more than one building. NSW Part J(A)1 Building Fabric. required exits from backstage must be independent of the audience evacuation routes.

It should also be noted that State and Territory authorities responsible for building regulatory matters may have issued advice, interpretations or guidelines to assist practitioners in applying the correct classification to a building or part. See Figure 6 for an indication of some Class 10 building configurations. The Objectives and Functional Statements for Part H1 are contained in Sections C, D and E of this Guide. . The reasoning is that the smaller size of the building and its lower number of occupants represents reduced fire risks. We pay our respect to their elders past and present and extend that respect to all Aboriginal and Torres Strait Islander peoples today.

When making their decision they consider the building's size, purpose, operations and the extent to which people are employed in the building. Some States or Territories may exempt some Class 10 buildings or structures (often on the basis of height or size) from the need to have a building permit.

This Part explains how each building classification is defined and used in the NCC. To set out the requirements for stairways to service platforms, rigging lofts, and the like. It should also be noted that State and Territory authorities responsible for building regulatory matters may have issued advice, interpretations or guidelines to assist practitioners in applying the correct classification to a building or part.

Class 7 buildings include those used to sell goods on the wholesale market, whereas Class 6 buildings are used to sell goods to the public. A Class 2 building is one that includes more than one dwelling, each of which is generally solely occupied by one or more people to the exclusion of others. The Deemed-to-Satisfy Provisions for a Class 7 or Class 8 farm building or farm shed do not prevent the ability to consider or develop a Performance Solution for a particular building where the requirements may not be considered appropriate or are viewed as too stringent. Also, the intent is not to allow sole-occupancy units in Class 2, 3 or 4 parts to be regarded as another Class such as Class 6 and then not have any fire or sound insulation between the units and any other classification which may have a high fire load and could endanger the occupants of the Class 2, 3 or 4 part.

Likewise, the lighting and equipment levels, people occupancy and load profiles for the area of minor use for the purposes of Volume One Section J must be in accordance with the use of the area.
