Can You Have a Door at the Top of Stairs?

One of the most common questions homeowners ask when planning a staircase renovation is whether a door can be placed at the top of the stairs. The answer involves Australian Building Code requirements, safety considerations and practical design solutions. Here's everything you need to know.

The Short Answer

Yes, you can have a door at the top of stairs in Australia — but only if there is an adequate landing between the door and the first step. The Building Code of Australia (BCA) requires a minimum landing of 750mm between any door and the top riser of a staircase. This ensures occupants have stable footing when opening or closing the door.

BCA Landing Requirements

The National Construction Code (NCC Volume 2, Part 3.9.1) sets clear requirements for landings at the top and bottom of staircases:

• Minimum landing depth — 750mm measured in the direction of travel
• Landing width — At least equal to the width of the staircase
• Level surface — Landings must be flat and level, with a maximum gradient of 1:50 for drainage on external landings
• Door clearance — The door swing must not encroach upon the required landing area

These requirements apply to all residential staircases in Queensland and across Australia. See our full guide to QLD stair regulations for more details.

Door Swing Direction

The direction a door swings is critical when positioned near stairs:

• Swing away from stairs (recommended) — The door opens into the room, away from the staircase. This is the safest configuration as it prevents the door from pushing someone towards the stairs
• Swing towards stairs (requires larger landing) — If the door must swing towards the staircase, the landing must be enlarged to accommodate the full arc of the door plus a standing area of at least 750mm
• Sliding or pocket doors — An excellent alternative that eliminates swing conflicts entirely

Safety Concerns

Placing a door at the top of stairs introduces several safety considerations:

• Trip and fall risk — A person stepping through a door directly onto stairs can lose balance, especially when carrying items
• Collision risk — Someone ascending the stairs may be struck by a door opening towards them
• Emergency egress — In an emergency, a door at the top of stairs can create a bottleneck or hazard
• Visibility — A door can obstruct the view of anyone approaching from the staircase

Proper staircase lighting at the landing is essential when a door is positioned near stairs.

Practical Design Solutions

If your floor plan requires a door near the top of the staircase, consider these solutions:

• Extend the landing — Increase the landing depth to 900mm or more for improved safety and comfort
• Use a sliding door — Cavity sliders or barn-style sliding doors eliminate swing conflicts
• Relocate the door — Moving the door further from the staircase opening is often the simplest solution
• Install a half-height gate — For child safety, a self-closing stair gate can be fitted at the landing without creating a full door obstruction

QLD-Specific Rules

Queensland adopts the Building Code of Australia under the Queensland Development Code. The QBCC (Queensland Building and Construction Commission) enforces these standards for all building work. If you're renovating or building a new staircase in Brisbane, Moreton Bay or the Sunshine Coast, your builder must ensure compliance with both the BCA and any local council requirements.

Craftsman Stairs is a QBCC licensed staircase builder (Licence #69007). We design and install staircases that fully comply with all applicable building codes. Contact us for expert advice on your staircase project, including door and landing configurations.
