Stair Safety: How to Install a Compliant Handrail

Stairs and ramps are common features in many properties, but they can also be a significant safety risk. A properly installed and compliant handrail is the single most effective way to prevent falls, protect occupants, and reduce your liability as a property owner or manager.

This guide outlines the essential Australian building code requirements for handrails, helping you understand what makes a handrail safe, compliant, and reliable.

Key Requirements for a Compliant Handrail

Building handrails isn't just about putting a rail on the wall. They must meet specific standards to be effective.

  • Correct Height: The handrail height, measured from the stair nosing or floor, must be at least 865mm. On landings or platforms where the fall height is 1 metre or more, a guardrail must be at least 1000mm high.
  • Continuous & Unobstructed: Handrails should be continuous for the full length of the stairway or ramp. There should be no obstructions on the rail that would break a handhold, such as a large post in the middle of the rail itself.
  • Optimal Grip: A handrail must be easy to grip. Circular handrails typically have a diameter between 30mm and 50mm, and there must be at least a 50mm clearance between the handrail and the adjacent wall.
  • Strong and Secure: The handrail must be securely fixed to the wall or support structure to withstand the force of someone using it for support.

When is a Handrail Required?

According to building codes, a handrail is required on at least one side of any stairway, platform, or landing that is more than 1 metre above the ground. This usually applies to any staircase with four or more risers.

Why Professional Installation is Essential

Handrail installation is a task that should always be handled by a professional, especially in strata buildings where there is a duty of care to maintain common property.

  1. Compliance with Codes: Professionals are up-to-date with the latest Australian building codes and standards (such as AS 1428 and AS 1657), ensuring your handrail is installed correctly from the start.
  2. Structural Integrity: An expert can determine the right anchor points and fixings to ensure the handrail is strong and secure, preventing it from failing when someone needs it most.
  3. Liability Protection: A professionally installed, compliant handrail helps protect you from potential liability issues should an accident occur on your property.
