If you’re planning a new build, renovation, or extension in South East Queensland, you’ll quickly come across three key planning controls: setbacks, site cover, and height limits. These rules play a major role in determining what you can build, where it can sit on your block, and how large it can be.
Understanding these requirements early can save you time, money, and unnecessary design changes. Here’s a clear breakdown of what each one means and how they affect your project.
What Are Setbacks?
Setbacks refer to the minimum distance a building must be positioned away from property boundaries.
Common setback types include:
- Front setback – Distance from the front boundary or street
- Side setbacks – Distance from side boundaries
- Rear setback – Distance from the back boundary
Setback requirements vary depending on:
- Your local council
- Zoning of the property
- Lot size and shape
- Whether the home is new or existing
- Character or heritage overlays
Setbacks help maintain streetscape consistency, privacy, access to light, and separation between neighbouring properties.
What Is Site Cover?
Site cover is the percentage of your block that can be covered by buildings and structures.
This usually includes:
- The house or building footprint
- Garages and carports
- Covered outdoor areas
It generally does not include:
- Driveways
- Open decks (depending on council)
- Landscaping and gardens
For example, if your block allows 50% site cover and your land is 600m², your total building footprint cannot exceed 300m².
Site cover limits are designed to:
- Prevent overdevelopment
- Allow room for landscaping and drainage
- Reduce flooding and stormwater issues
Understanding Height Limits
Height limits control how tall a building can be and are usually measured:
- In metres, and/or
- By number of storeys
Height restrictions can vary significantly based on:
- Zoning
- Overlays (character, flood, airport noise, etc.)
- Slope of the land
In Brisbane, for example, character homes may have stricter height controls to maintain the look and scale of traditional streetscapes.
Why These Rules Matter
Setbacks, site cover, and height limits directly influence:
- Overall building size
- Floor plan layout
- Outdoor space and landscaping
- Approval pathways (accepted development vs development application)
If a design does not comply, you may need:
- A development application (DA)
- Design changes to meet code
- Additional reports or planning justification
This can add time and cost if not considered early.
Can You Build Outside These Limits?
In some cases, yes, but it depends.
Non-compliant designs may still be approved if:
- Performance outcomes are met
- Neighbour impacts are minimal
- A strong planning argument is provided
This is where experienced building designers and town planners add real value, helping you understand when flexibility is possible and when it’s not.
