In Queensland, the approval process for a portable office is regulated at both the state level (via the Planning Act 2016 and Building Act 1975) and the local level. Whether you are in Brisbane, the Gold Coast, or the Sunshine Coast, you must navigate a specific hierarchy of “checks.”

Here is a detailed checklist to guide your local council approval process.

1. Step One: Zoning & Planning (The “Can I put it here?” Check)

Before looking at the building itself, you must determine if the land use is permitted.

• [  ] Identify the Zone: Use your local council’s online mapping tool (e.g., Brisbane’s City Plan online or Gold Coast’s PD Online) to find your property’s zoning (Residential, Commercial, Industry, etc.).
• [  ] Check Overlays: Does the property have a Heritage, Flood, or Bushfire overlay? These can trigger a mandatory Development Application (DA) even for small units.
• [  ] Define the Use: Is it a “Home Office” (ancillary to a house) or a standalone “Office”? Commercial offices in residential zones almost always require a DA for “Material Change of Use” (MCU).
• [  ] Verify Setbacks: Ensure the unit is at least 1.5m from side/rear boundaries and 6m from the road (standard QLD codes), otherwise, you’ll need a “Siting Variation” approval.

2. Step Two: Building Approval (The “Is it safe?” Check)

Nearly all portable offices in QLD require Building Approval (BA) from a private certifier.

• [  ] Engage a Private Certifier: In QLD, councils generally don’t do the building certification themselves; you must hire a licensed private certifier.
• [  ] Wind Rating (RPEQ): Ensure the unit has an RPEQ-certified engineering design. For Queensland (especially coastal areas like the Gold Coast or Sunshine Coast), the unit must be rated for at least Wind Region B (or Region C if in the far north).
• [  ] Form 15 & 16: Obtain a Form 15 (Compliance Certificate for Design) from the manufacturer and a Form 16 (Inspection Certificate) once the footings and installation are complete.
• [  ] Energy Efficiency: Ensure the unit meets NCC Section J (for commercial buildings) regarding insulation and glazing—essential for the QLD heat.

3. Step Three: Plumbing & Drainage (The “Amenities” Check)

If your portable office includes a toilet, shower, or kitchenette, this is a separate approval stream.

• [  ] Plumbing Permit: You must lodge a permit with the local council’s plumbing department.
• [  ] Regulated Work: Only a licensed plumber can perform the connection. They must lodge a Form 4 (Notifiable Work) with the QBCC or a local government permit depending on the complexity.
• [  ] Waste Management: If not connecting to the main sewer (e.g., in rural acreage), you will need an On-site Sewerage Facility (OSSF) permit.

4. Step Four: Site Preparation & Utilities

• [  ] Electrical Safety: Connection to the grid must be done by a QLD-licensed electrician. If the office is on a construction site, it must meet AS/NZS 3012 standards (Construction and Demolition sites).
• [  ] Foundations: The certifier will require an inspection of the “tie-downs.” In QLD, portable units must be securely anchored to prevent movement during storm cells.

5. Final Stage: Lawful Occupation

• [  ] Certificate of Occupancy: Once the certifier is satisfied that the planning, building, and plumbing requirements are met, they will issue a Form 11 (Certificate of Occupancy).
• [  ] Lodge with Council: The certifier will lodge the final paperwork with the local council for their records. You are now legally clear to work!
