Frequently asked questions - Criterion 6

Q Do the clear opening widths for doorways apply to all doors or just those on the entrance level?

A The clear opening widths apply to all doorways and hallways/passageways/landings on all storeys within all dwellings, whatever form, on whatever storey, and all communal areas within a block of dwellings.

Q Is the 300mm nib required to room doors or just the entrance door?

A The 300mm nib requirement applies to all communal doors, and all doors on the entrance level within every dwelling. All room doors within a flat would therefore require the nib. All entrance doors into communal hallways or individual dwellings also require the nib.

Q Is the nib requirement only on the pull side of the door?

A The 300mm nib dimension relates to the latch side of the door only on the pull side of the door. No nib is required on the push side of the door. See diagram below (Figure 3).

Q What is meant by ‘clear opening’?

A ‘Clear opening’ refers to the clear effective opening of the door which is defined as: The opening width, measured in the same plane as the wall in which the door is situated, between a line perpendicular to the wall from the outside edge of the doorstop on the latch side and the nearest obstruction on the hinge side when the door is open at 90 degrees or more. The nearest obstruction may be projecting door furniture, a weatherboard, the door itself, or the door stop.
