STAIR TREAD AND STAIRWAY
stair tread and stairway landing compliance
The Building Code of Australia (BCA) and Australian Standards (AS1428.4) now require all new buildings to include slip-resistant stair treads. This is to provide safe access and mobility to all users.
According to the Building Code of Australia and Disability Discrimination Act (ODA), it is also mandatory to provide a stair nosing with horizontal depth between 50mm and 75mm on all steps.
