Approvals can seem like a maze of acronyms and authorities. In practice, the pathway for a new home in Queensland follows a predictable logic. Understanding it helps you plan realistic timeframes and avoid costly redesigns.
The two main types of approval
Building approval (always required)
Every new home needs a building approval, also called a building development approval. It confirms that the design complies with the National Construction Code (NCC), the Queensland Development Code (QDC) and the relevant Australian Standards. In Queensland, building approvals are usually issued by a private building certifier licensed by the QBCC, rather than by council.
Planning approval (sometimes required)
Some homes also need council planning approval: a development application assessed by council against the local planning scheme. Whether one is needed depends on the zone, any overlays and how the design compares with the scheme's requirements. Common triggers include:
- A character, heritage or other overlay on the property
- Proposals that exceed the planning scheme's height, site cover or setback requirements
- Steep land, flood-affected land or significant vegetation
If your design meets all of the planning scheme's "acceptable outcomes", planning approval may not be needed. Where it departs from them, the application is assessed against the "performance outcomes", which takes longer and involves more uncertainty.
Siting variations and concurrence agency referrals
The QDC sets standard boundary setbacks, site cover and height rules for houses. If your design doesn't meet them, the certifier may need a concurrence agency referral to council (often called a siting variation or "relaxation"). Council considers matters such as amenity, overshadowing and streetscape. This is common on small or awkwardly shaped blocks.
Other approvals and reports you may need
- Energy efficiency assessment: to show compliance with the 7-star and whole-of-home requirements.
- Plumbing and drainage approval: for new sanitary drainage and plumbing work.
- Bushfire (BAL) assessment: in bushfire-prone areas.
- Flood certification: confirming floor levels where a flood overlay applies.
- Build-over-sewer approval: from the water authority (for example, Urban Utilities in Brisbane) if building near or over a sewer main.
- Driveway and crossover approval: from council for new or modified driveway access.
- Demolition approval: if an existing house is being removed, particularly in character areas.
Inspections during construction
The certifier, or a competent person engaged on their behalf, inspects the work at mandatory stages. These typically include footings, slab, frame and final. Engineers usually inspect structural elements such as reinforcement and steel. After the final inspection the certifier issues a Form 21 final inspection certificate for a house, which is your confirmation that the work has been completed in line with the approval.
Typical timeframes
Timeframes vary between councils and depend on how complete the application is. As a broad guide:
- Building approval with a certifier only: often a few weeks once documentation and reports are complete.
- Concurrence agency referral (siting variation): adds weeks, depending on council.
- Council planning approval: can take several months, especially if council requests further information.
How to keep approvals on track
- Check overlays and constraints before design starts so the design responds to them from day one.
- Design to "acceptable outcomes" where you can. Each departure adds time and risk.
- Lodge complete documentation. Incomplete applications are the most common cause of requests for information and delay.
- Engage the certifier early on complex projects, so compliance questions are answered during design rather than after.
- Allow realistic time in your program before committing to finance or lease dates.
