When planning to construct a garage, garden shed, carport, or shade sail, which are classified as Class 10 structures, it is essential to understand the certification process to ensure compliance and smooth approval. Below is a concise guide to help you navigate the requirements for obtaining Class 10 certification.
Key Requirements:
- Application Form: Complete and submit DA Application Form 2. Ensure to fill out the ‘Email address’ section as the Council processes applications electronically.
- Project Valuation:
- If the project value is $3,300 or more and carried out by a QBCC licensee, you must notify the Queensland Building and Construction Commission (QBCC).
- For owner-builders, QBCC notification is required if the value exceeds $11,000.
- Documentation:
- Site Plan: Provide a scaled site plan (minimum 1:200) showing property boundaries, existing buildings, setbacks, and proposed structure dimensions.
- Cross Section: A detailed cross-section (minimum 1:50) showing framing sizes, footings, spans, connections, and construction details.
- Engineer’s Design Certification: Necessary for structures with steel members, including Form 15 for engineer certification.
- Bracing and Tie-down Details: Ensure these details are included for the proposed structure.
- Footing/Slab Design: This should comply with AS2870 standards or be certified by a Registered Professional Engineer of Queensland (Form 15).

- The structure exceeds specific height or length limits relative to boundaries.
- Council Infrastructure: Ensure the structure is clear of council services. Special provisions may be required for base and footings if building near council infrastructure.
- Timber and Metal Frames: Follow AS1684 for timber frames and provide structural engineering details with Form 15 for metal frames.
