Handrails on private and common stairs
Private stairs with a rise over 600 mm and common stairs in blocks of dwellings must have continuous handrails on at least one side (if under 1000 mm wide) or both sides (if 1000 mm or wider), with single handrails on tapered-tread flights positioned on the outer side.
Flights in a private stair with a total rise of more than 600 mm and a common stair in a block of dwellings, should have a continuous handrail that gives firm support and a firm grip and be located –
(a) on at least one side where the stair is less than 1000 mm wide; or
(b) on both sides where the stair is 1000 mm wide or more.
Where only one handrail is required on a flight with tapered treads, it should be located on the outer side of the flight.
