Are you planning to build a staircase in your home or business in Australia? Well, you’re in luck because in this blog post, we’re going to talk all about staircase standards in Australia! It may sound like a dry topic, but we promise to make it as fun and easy to read as possible. So, let’s dive right in!

What are Staircase Standards?

Staircase standards are a set of guidelines and regulations that ensure the safety of those who use the stairs. These standards cover various aspects of stair design, including the height and depth of steps, the width of the staircase, the placement of handrails, and much more.

These standards vary from country to country, and even within countries, there may be different standards for different types of buildings.

Staircase Standards in Australia

In Australia, the staircase standards are set by the Building Codes Board, which is a national code that sets out the minimum requirements for building construction. The BCB covers everything from fire safety to structural integrity, and of course, staircase design.

Let’s take a closer look at some of the key staircase standards in Australia:

  • Staircase Width: The minimum width of a staircase in Australia is 900mm for residential buildings and 1200mm for commercial buildings. This width is measured between the handrails and includes any landings.
  • Tread and Riser Dimensions: The tread (the flat part of the step) must be at least 240mm wide, and the riser (the vertical part of the step) must be no more than 190mm high. The maximum difference in riser height between consecutive steps must be 12mm.
  • Handrails: Handrails are required on both sides of a staircase and must be between 865mm and 1000mm above the nosing (the front edge of the tread). The handrail must also be continuous and extend beyond the top and bottom steps.
  • Lighting: Staircases must be well-lit to ensure visibility and safety. The BCB requires a minimum of 5 lux (a measure of illumination) on stairs and landings.

These are just a few examples of the staircase standards in Australia. If you’re planning to build a staircase, we highly recommend consulting the BCB for a complete list of requirements.

Why Are Staircase Standards Important?

Staircase standards are essential for ensuring the safety of those who use the stairs. Falls on stairs can result in serious injuries, and even fatalities, so it’s crucial that stairs are designed and built to a high standard.

In addition to safety concerns, building codes and standards are also important for legal and insurance purposes. If a staircase is not up to code, and someone is injured as a result, the building owner could be held liable. Insurance companies may also refuse to cover claims related to accidents on non-compliant staircases.
