Installing a new staircase — whether it's an internal timber staircase or an external staircase — involves more than choosing a design. One of the most common questions homeowners in Brisbane, Moreton Bay and the Sunshine Coast ask is whether planning permission is required. The short answer: it depends on the scope of work. Here's what you need to know.
When Is Planning Permission Required?
In Australia, the terms "planning permission" and "building approval" are often used interchangeably, but they refer to different processes. Planning permission (or a development application) relates to land use and development controls — typically managed by your local council. Building approval ensures the work complies with the Building Code of Australia (BCA) and is issued by a private building certifier or council.
For most internal staircase replacements and new installations within an existing building envelope, you will need a building approval but not necessarily planning permission. However, if your staircase project involves:
- Changes to the external appearance of a heritage-listed building
- New external staircases that extend beyond the existing building footprint
- Structures within setback zones or boundary clearances
- Work on a property in a character overlay or conservation area
...then you may need a development application (DA) in addition to a building approval.
Building Approval vs Planning Permission
A building approval is almost always required for staircase work in Queensland. This is obtained through a private building certifier who assesses your plans against the BCA requirements for:
- Riser height (115–190mm for residential)
- Tread depth (minimum 240mm going)
- Handrail height (minimum 865mm residential)
- Balustrade spacing and height requirements
- Headroom clearance (minimum 2,000mm)
- Landing dimensions and door clearances
Queensland-Specific Requirements
Queensland uses the Queensland Development Code (QDC) alongside the BCA. Key considerations for QLD homeowners include:
- QBCC licensing: All structural building work, including staircase construction, must be performed by a QBCC licensed builder.
- Bushfire areas: Properties in designated bushfire-prone areas may have additional requirements for external staircases.
- Flood zones: Staircases connecting to ground-level areas in flood-affected zones must comply with minimum habitable floor levels.
Exempt and Self-Assessable Work
Some minor building work in Queensland is classified as "exempt" — meaning no building approval is needed. However, staircase construction is generally not exempt because it is considered structural work that affects the safety and amenity of the building. Even replacing an existing staircase with a like-for-like design typically requires certification.
BCA Compliance for Staircases
The Building Code of Australia sets out detailed requirements for staircase dimensions, handrail specifications and slip resistance. Compliance with these standards is mandatory and will be verified by your building certifier during the approval and inspection process. Non-compliant staircases may need to be rectified before a final inspection certificate is issued.
Why You Should Hire a QBCC Licensed Builder
Working with a QBCC licensed staircase builder ensures your project is compliant from the start. A licensed builder will:
- Advise on which approvals are required for your specific project
- Prepare plans and documentation for the building certifier
- Ensure the staircase meets all BCA and QDC requirements
- Carry appropriate insurance, protecting you from liability

Frequently Asked Questions
Do I need council approval to replace an existing staircase?
Generally, a like-for-like replacement of an existing staircase does not require council planning approval. However, you will still need a building approval (BA) to ensure the new staircase complies with the Building Code of Australia (BCA) and Queensland Development Code.
What approvals do I need for an external staircase in QLD?
External staircases typically require a building approval from a private building certifier. If the staircase changes the building's footprint or is near a boundary, you may also need a development application (DA) through your local council.
Can I install a staircase myself without a licence?
In Queensland, structural building work including staircase installation must be carried out by a QBCC licensed builder. DIY structural work is not permitted and could void your home insurance and create safety liabilities.
