Class 2 buildingsĪ Class 2 building is generally a building containing two or more sole occupancy units such as an apartment building and each sole occupancy unit is a single dwelling.Ī ‘sole occupancy unit’ is a room or other part of a building for occupation by one or joint owner, lessee, tenant, or other occupier to the exclusion of any other owner, lessee, tenant, or other occupier.

It is important to note that a single dwelling that is located above another classification of building other than a private garage is not a Class 1 building which is explained below.Īlso if you have a single dwelling with habitable outbuildings they are also part of the Class 1a dwelling, for example a ‘sleep out’ in the backyard. The main difference between a Class 1a and Class 1b is the fire safety requirements in that a Class 1b has more stringent provisions around smoke alarms and also requires a level of disability access.

These can include row houses, terrace houses, townhouses or villa units.Ī Class 1b building is a smaller boarding house, guest house or hostel that may be commonly referred to as a ‘bed and breakfast’ accommodation that cannot accommodate more than 12 people and the floor area cannot exceed 300m2.Ī Class 1b also includes four or more single dwellings located on one allotment and used for short-term holiday accommodation. There are two types of Class 1 buildings:Ĭlass 1a is a single detached dwelling (house) or can also be one or more attached dwellings that will share a common wall (party wall). The following provides details and examples of the various classifications of buildings as provided in the National Construction Code (NCC).
