Approvals/authorised person
Assessable development
- Where a wall is deemed ‘assessable development’ and requires building approval from a private building certifier, and must meet all of the requirements of the Building Regulation 2006, the Building Code of Australia (current edition) and the Sunshine Coast Planning Scheme 2014.
QBCC licensed builder
In Queensland, individuals and companies must hold a Queensland Building and Construction Commission (QBCC) license to carry out:
- Any building work valued over the QBCC amount (includes all labour and material costs regardless of who supplies the materials).
Walls
A wall is regarded as a non-habitable structure under the BCA and requires building approval from a private building certifier where the wall is:
- Over 1.0 m high above the adjacent natural ground level.
- Under pressure from an adjacent surcharge loading (such as a driveway).
- Where the wall is located within 1.5 m of a building or another retaining wall.
- Where a fence is connected to the wall.
- Walls over 1.0 m high, must be designed by a suitably qualified engineer in accordance with all relevant codes and Standards.
- Footing design for walls is to be designed by a suitably qualified engineer.
- A retaining wall greater than 1.0 m high must be designed and certified by an RPEQ, and must include a fall barrier in accordance with Sunshine Coast Planning Scheme.
Coastal management district
- Ensure appropriate environmental approvals are obtained and the conditions observed where any building work is proposed in the Coastal Management District.
- Consult with Queensland Government Department of State Development, Infrastructure and Planning (DSDIP) – State Assessment and Referral Agency (SARA) for application forms, guidelines and information sheets.
Other
- Ensure all relevant approvals are obtained from the appropriate governing bodies and all conditions are observed.
- Department of Transport and Main Roads (DTMR) approval is required for works near state controlled roads. This applies to any part of the road reserve including pathways, kerb and channelling, nature strip and traffic island.
