A stairway that provides access to a service platform, rigging loft, or the like, must comply with AS 1657. with the seat in the up position if folding seats are used; or, an evacuation route from the stage side of a proscenium must not pass through the proscenium; and. 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. Where a building with external combustible cladding is made up of different uses and contains a Class 2, 3 or 9 use, then the owner must register the building no matter how small or how far away from the cladding the Class 2, 3 or 9 part is located. 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. This would include a call-out cost estimated to be $2,000 - $4,000 as a one-off cost. For example, if people are likely to be employed to stack materials/produce in a storage building or remove materials/produce from a storage building then a classification of Class 7b may be appropriate. Each part of a building must be classified according to its purpose and comply with all the appropriate requirements for its classification. H1.4(c) allows a reduced width in such cases. See also Volume One Table D3.1 which contains an explanation of what is considered be "one allotment". We pay our respect to their elders past and present and extend that respect to all Aboriginal and Torres Strait Islander peoples today. required exits from backstage must be independent of the audience evacuation routes. have a sprinkler system (other than a FPAA101D or FPAA101H system) complying with Specification E1.5; or. As can be seen from the definition of a Class 6 building, it includes a hotel bar which is not an assembly building. The NCC has definitions of "farm building" and "farm shed" which are certain Class 7 and 8 buildings used for farming purposes. A Class 9b building is an assembly building which is defined to include a building where people may assemble for entertainment, recreational or sporting purposes. Unless another classification is more suitable an occupiable outdoor area must have the same classification as the part of the building to which it is associated. The maximum gap of 125 mm stipulated in is consistent with . In a case where the classification is unclear, a decision should be made according to the perceived risks inherent in the use of the building. The classification of a building or part of a building is determined by the purpose for which it is designed, constructed or adapted to be used.

Class 2 buildings can be attached to buildings of another Class. When two or more dwellings are attached to another Class, they cannot be Class 4 parts, as any building can only contain one Class 4 dwelling. For A6.3, a Class 3 building is not a Class 1 or 2 residential building. A building (or part of a building) may also have more than one such purpose and may be assigned more than one classification. A sole-occupancy unit used for residential purposes located over another sole-occupancy unit used for residential purposes will always be a Class 2 or Class 3 building (depending on the circumstances). Class 9a buildings are health-care buildings, including day-care surgeries or procedure units and the like. For example, if the intended use of a building is to grow or store a large amount of tomatoes, such as a large greenhouse, and there is likely to be only one to two persons in the building at any time, it is considered inappropriate to classify the building as a Class 10a under the Deemed-to-Satisfy Provisions and a classification of Class 7 or Class 8 would be more appropriate. The audience must be protected from this fire source by either: A proscenium wall must comply with Specification H1.3. 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. Wholesale means sale to people in the trades or in the business of on-selling goods and services to another party (including the public). have the stage, backstage area and accessible under stage area separated from the audience by a proscenium wall in accordance with H1.3. These Class 1, Class 2 or Class 3 parts need not be attached to one another, nor be more than a single storey. Class 10a - A private garage, carport, shed or the like. It cannot be a Class 1 building. Class 5 buildings include professional chambers or suites, lawyers' offices, government offices, advertising agencies and accountants' offices. They will look at what classification the building most closely resembles. The Deemed-to-Satisfy Provisions of this Part apply to every enclosed Class 9b building or part of a building which . 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. However, a building could be a mixture of Class 3 and another Class. Note that a habitable building such as a sleepout cannot be classified as a Class 10 building. Classification is a process for understanding risks in a building or part, according to its use. The NCC groups buildings and structures by the purpose for which they are designed, constructed or adapted to be used, rather than by the function or use they are put to, assigning each type of building or structure with a classification. Professional Engineers must also be registered. This slope cannot be used in aisles required to be accessible by people with disabilities. A Class 7 building is a storage-type building that includes one or more of the following sub-classifications: Class 7b a building that is used for storage, or display of goods or produce for sale by wholesale. Under H1.1(b)(i), H1.4 applies to all Class 9b buildings, both enclosed and open. Class 1b (1) (a) Dwellings located on one allotment (2) and used for shortterm holiday accommodation consisting of: To and within: . See to determine which buildings need to comply with . 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. METHOD OF COMPLIANCE WITH H1.4(b) IF DIFFERENCE BETWEEN LEVELS IS 230-400 MM. The certification may require fire services to arrive on site and assess the situation physically. A small toolshed, used for trade-related hobbies for non-commercial purposes or home repairs, on the same allotment as a Class 1 building, would be classified as a Class 10 building. Class 4 is a dwelling in a Class 5, 6, 7, 8 or 9 building. It is possible for a single building to have parts with different classifications. Class 1b buildings used for short-term holiday accommodation include cabins in caravan parks, tourist parks, farm stay, holiday resorts and similar tourist accommodation. Volume Three - contains the requirements for plumbing and drainage for all classes of buildings. the gradient of the floor surface must not be steeper than 1 in 8, or the floor must be stepped so that, a line joining the nosings of consecutive steps does not exceed an angle of 30 to the horizontal; and, the height of each step in the stepped floor is not more than 600 mm; and, the height of any opening in such a step is not more than 125 mm; and, if an aisle divides the stepped floor and the difference in level between any 2 consecutive steps, exceeds 230 mm but not 400 mm an intermediate step must be provided in the aisle; and, exceeds 400 mm 2 equally spaced intermediate steps must be provided in the aisle; and, the going of intermediate steps must be not less than 270 mm and such as to provide as nearly as practicable equal treads throughout the length of the aisle; and, the clearance between rows of fixed seats used for viewing performing arts, sport or recreational activities must be not less than, 300 mm if the distance to an aisle is not more than 3.5 m; or. Such decisions are determined on a case-by-case basis. Typical outbuilding classifications include the following: Provisions relating to Class 10c structures are only intended to address private bushfire shelters associated with a single Class 1a dwelling. applies to all Class 9b buildings, whether or not they are enclosed, and regardless of size. Under A6.11 each part of a building (including the entire building) may have more than one classification. For example, if the intended use of a building is to grow or store a large amount of tomatoes, such as a large greenhouse, and there is likely to be only one to two persons in the building at any time, it is considered inappropriate to classify the building as a Class 10a under the Deemed-to-Satisfy Provisions and a classification of Class 7 or Class 8 would be more appropriate. A Class 6 building is a building where goods or services are directly sold or supplied to the public. Class 2 buildings can be single storey attached dwellings. A Class 9 building is a building of a public nature that includes one or more of the following sub-classifications: Class 9a a health-care building including any parts of the building set aside as laboratories, and includes a health-care building used as a residential care building. The NCC groups buildings and structures by the purpose for which they are designed, constructed or adapted to be used, rather than by the function or use they are put to, assigning each type of building or structure with a classification. For A6.0(1) where a part of a building has been designed, constructed or adapted for a different purpose and is less than 10% of the floor area of the storey it is situated on, the classification of the other part of the storey may apply to the whole storey. 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. Stages used for live performances can contain high fire loads due to the props, scenery, lighting, and the like used in such productions. Accommodation for the aged, children, or people with disability. The construction details for a proscenium wall are contained in . Class 9c buildings are residential care buildings that may contain residents who have various care level needs. Stages used for live performances can contain high fire loads due to the props, scenery, lighting, and the like used in such productions. Examples of a Class 6 building may include. A sleepout on the same allotment as a Class 1 building is part of the Class 1 building. The requirements of (a) do not apply to a material or assembly if it is . This width is based on studies of movement between rows. However, when that use is minor compared with the remainder of the bar, such as a piano bar or the like where patrons only listen to music and there is no dance floor, the appropriate authority should exercise judgement on the predominant use and therefore the appropriate classification of the bar. The first is a carpark as defined in the NCC. It is not unusual for a manager's, owner's or caretaker's dwelling attached to a Class 3 building to be thought of as a Class 4 part of the Class 3 building. The length of stay is unimportant. 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.

Suite 5, 5 Green St Maroubra NSW 2035 02 9700-8600. A Class 1 building includes one or more of the following sub-classifications: Class 1a is one or more buildings, which together form a single dwelling including the following: One of a group of two or more attached dwellings, each being a building, separated by a fire-resisting wall, including a row house, terrace house, town house or villa unit. This Part explains how each building classification is defined and used in the NCC. Hence, it is not intended to restrict the resident type and provides maximum flexibility for service providers, residents and the community. A6.9(2) excludes any parts of the building that are of another Class. four or more single dwellings located on one allotment and used for short-term holiday accommodation. They would only make this decision if a classification of Class 7 or Class 8 would not be more appropriate. Such buildings must not be otherwise classified as a Class 1 or Class 3 building or Class 4 part. 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. NSW Part J(A)2 Building Sealing. These buildings can include. H1.7 applies to every enclosed Class 9b building. has a stage with an associated rigging loft. Class 10b structures are non-habitable structures. Class 1b is one or more buildings which together constitute, a boarding house, guest house, hostel or the like that, would ordinarily accommodate not more than 12 people; and, have a total area of all floors not more than 300 m2 (measured over the enclosing walls of the building or buildings); or. Where there is any common space below such dwellings, they are Class 2 (and cannot be Class 1) irrespective of whether the space below is a storey or not (see Figure 5). Class 4 classification applies to some types of accommodation located within a Class 5-9 building. The Class 9c classification recognises that many residents progress through a continuum of care needs from low to high. In most cases, each of these parts is a separate classification. In the spirit of reconciliation the Australian Building Codes Board acknowledges the Traditional Custodians of country throughout Australia and their connections to land, sea and community. A room that contains a mechanical, thermal or electrical facility or the like that serves the building must have the same classification as the major part or principal use of the building or fire compartment in which it is situated. They will also take into account the likely fire load, plus, the likely consequences of any risks to the safety, health and amenity of people using the building. required exits from backstage must be independent of the audience evacuation routes. Some establishments claim to sell goods to both the wholesale and retail markets. Throughout class 1 - 9 buildings if any part of the building has an effective height of more than 25 m. Table E1.5 REQUIREMENTS FOR SPRINKLERS The type of sprinkler system to be installed will depend on the hazard classification of the building according to the NCC. Unless another classification is more suitable an occupiable outdoor area must have the same classification as the part of the building to which it is associated. Multi-care level facilities are for residents who may require the full range of care services outlined by the Aged Care Act. The maximum slope of the floor of 1 in 8 is consistent with D2.10(b)(ii). NSW Subsection J(A) Energy efficiency Class 2 building and Class 4 parts. theatres, cinemas and halls, churches, schools, early childhood centres, kindergartens, preschools and child-minding centres; and, indoor cricket, tennis, basketball centres and sport stadiums; and, nightclubs, discotheques, bar areas providing live entertainment and/or containing a dance floor, public halls, dance halls and other places of entertainment; and. 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. A stage and backstage area of a theatre or public hall has a high fire load due to the storage of props and scenery/etc. Part H1 contains Deemed-to-Satisfy Provisions additional to those contained in Sections C, D and E for Class 9b buildings. Hence, it is not intended to restrict the resident type and provides maximum flexibility for service providers, residents and the community. Where the potential exists for residents of varying care needs to be accommodated, consideration of the Class 9c provisions may be appropriate. To set out the detailed construction requirements for a proscenium wall. The most common way to describe a Class 8 building is as a factory. It is not unusual for a manager's, owner's or caretaker's dwelling attached to a Class 3 building to be thought of as a Class 4 part of the Class 3 building. However identification of low fire load, low occupant risk and low risk of fire spread should not be used as justification for choosing a less stringent building classification for a building under the Deemed-to-Satisfy Provisions. Class 5 buildings include professional chambers or suites, lawyers' offices, government offices, advertising agencies and accountants' offices. The reasoning is that the smaller size of the building and its lower number of occupants represents reduced fire risks. However, if any other part of the principal building is used for accommodation, for example, the attached shop is converted into an additional flat, both flats become classifiable as Class 2 or, depending on their use, possibly Class 3. Class of building. A detached entertainment room on the same allotment as a Class 1 building, perhaps associated with a. For example, it may be appropriate to classify a shed which is used to store a tractor as a Class 10a building. has a stage with an associated rigging loft. in the case of school assembly, church or community halls, contain both a stage and backstage area which exceeds 300 m, are not covered by , and have a stage and backstage area which exceeds 200 m, the installation of a sprinkler system; or. To enable safe egress from the stage and backstage areas of a theatre. The attached Class 2 buildings need not be attached to one another, and need not be more than a single storey. NSW Part J(A)2 Building sealing. Building work that consists of non-structural work on abuilding, regardless of the class for the building; or the gross floor area of the building. However, a number of farm buildings and farm sheds are often not only used for the storage of farm vehicles, but to store supplies such as fuel, grain or hay. For example, it may include what is ordinarily called a house, plus one or more habitable outbuildings such as sleepouts. When two or more dwellings are attached to another Class, they cannot be Class 4 parts, as any building can only contain one Class 4 dwelling. A Class 5 building is an office building used for professional or commercial purposes. Class 3 buildings are a common place of long term or transient living for a number of unrelated people. When does a Class 3 motel unit become a Class 2 holiday flat and vice versa? The classification of a building or part of a building is determined by the purpose for which it is designed, constructed or adapted to be used. See Figure 4 for a typical configuration of Class 1 and Class 2 buildings. Some classifications also have sub-classifications, referred to by a letter after the number (e.g. The Deemed-to-Satisfy Provisions of this Part apply to every enclosed Class 9b building or part of a building which, is a school assembly, church or community hall with a stage and any backstage area with a total floor area of more than 300 m2; or, otherwise, has a stage and any backstage area with a total floor area of more than 200 m2; or. NSW Part 3.12.3 Building sealing. See Figure 6 for an indication of some Class 10 building configurations. A single Class 1 dwelling can be made up of more than one building. applies only where the public is seated on fixed seating to view an event. Such decisions are determined on a case-by-case basis. A Class 7a classification may still be appropriate where the majority of the shed's space is intended to be designated for the parking of vehicles. In the spirit of reconciliation the Australian Building Codes Board acknowledges the Traditional Custodians of country throughout Australia and their connections to land, sea and community. It is also recognised that the specific care needs of the residents may result in a greater minimum number of staff. If there are two or more dwellings, they are Class 1, Class 2, or possibly Class 3. See also Volume One Table D3.1 which contains an explanation of what is considered be "one allotment". However, a Class 4 part of a building can only be part of a Class 5-9 building. The second is a building used for storage, often referred to as a warehouse. Class 9can aged care building. For A6.3, a Class 3 building is not a Class 1 or 2 residential building. These concessions allow people to rent out rooms in a house, or run a bed and breakfast, without having to comply with the more stringent Class 3 requirements. A Class 2 building is a building containing two or more sole-occupancy units. To enable safe egress from the stage and backstage areas of a theatre. To protect the audience in a theatre or public hall from a fire on the stage. Such props and scenery are often also stored in backstage areas, which adds to the fire load. lighting is dimmed or extinguished during public occupation; and. Many older people enter residential care with low care needs (typically Class 3 facilities) but, as they age, require higher levels of care. These are outlets used for the servicing of cars and the selling of fuel or other goods. Class 1 buildings are not located above or below another dwelling, or another class of building other than a private garage.
