Council Approval & Compliance for Mezzanine Floors

If you are planning a mezzanine in a Queensland warehouse, factory or workshop, mezzanine building approval Queensland businesses need is a certifier-led process, not a single form lodged with council. Knowing who does what, and in what order, saves you from the delays that come from starting the paperwork late.

This guide walks through the Queensland building approval pathway for a commercial or industrial mezzanine, the documents you should have ready, and the points where projects most often slow down. It is general guidance only. Your building certifier will confirm what applies to your site.

Does a Queensland mezzanine need building approval?

Building work in Queensland needs a building development approval unless it is accepted development under the Building Regulation 2021 (Schedules 1 and 2). Some work may also need approval under the local council planning scheme. That is the position set out by Business Queensland.

For a mezzanine, the practical advice is simple: do not assume your project is accepted development. Ask your certifier to confirm in writing before you commit to a design or a start date. A free-standing steel platform inside a shed still carries people, stock and sometimes plant, so it is the kind of work you want assessed properly.

Who issues the approval: the building certifier

In Queensland, building approvals are issued by a building certifier. That may be a private certifier or one employed by a council. Certifiers are licensed by the QBCC, and they assess, inspect and certify work against the Building Act 1975, the BCA and the Queensland Development Code. You can read more about the role on the QBCC website and on Business Queensland.

This is the main difference from what many people expect. You are not usually waiting on a council counter. You are engaging a certifier, giving them a complete set of drawings, and responding to their assessment.

Brisbane City Council gives a useful local example. It states that you must receive building approval from a private certifier before final building certification, and that the certifier lodges the documents with Council. The detail is on the Brisbane City Council certifier information page. Other councils will have their own arrangements, so check yours.

The approval pathway, step by step

Every site is different, but a commercial mezzanine in Queensland generally follows this order.

1. Confirm the building and the proposed use

Start with what the mezzanine is for: storage, production, or an office or amenity area. The use shapes the design, the access and the way your certifier looks at the project. Have the existing building's approved plans to hand if you can find them.

2. Check the size against the NCC storey test

Under NCC 2022 Volume One, clause C2D3(4), a mezzanine is regarded as a storey when calculating rise in storeys if its floor area is more than 200 m² or more than one-third of the floor area of the room, whichever is the lesser. Two or more mezzanines at or near the same level are aggregated for this test. The clause is on the ABCB website.

The ABCB guidance explains why: larger mezzanines are counted because of their potential fire load, and rise in storeys feeds into the fire-resisting construction requirements. Your certifier will confirm how this applies to your building. It is worth knowing early, because it can influence the size and staging of a project.

3. Get engineered drawings

Your certifier needs enough detail to assess the structure, access and safety features. In practice that means engineered drawings and supporting documentation prepared for your specific slab and building. Our team prepares engineered designs for this stage.

4. Check whether the planning scheme is involved

Separately from the building approval, some work may need approval under the local council planning scheme. Whether it does depends on your site, your zone and the nature of the work. Your certifier or a town planner can tell you, and it is much better to find out before fabrication starts than after.

5. Lodge, assess and build

Once the certifier is satisfied, the building approval is issued and installation can proceed. The certifier inspects and certifies the work as it progresses.

6. Certificate of occupancy before use

A certificate of occupancy (formerly the certificate of classification) is required before a class 1b to 9 building is used or occupied after building work. That includes the commercial and industrial classes 5 to 9. It is issued by the certifier, as set out on Business Queensland.

In other words, do not load the new floor with stock or move staff upstairs until the certifier has signed off.

Site conditions that add approval steps

Some Queensland sites bring extra requirements, and our past projects show how varied they can be.

• Flood-affected land. At Grevillea Distribution, a Brisbane wholesaler had limited ground-level space, structural restrictions and flood-zone compliance requirements, and needed to expand without disrupting operations.
• State-controlled roads. The BSeen Promotions project site sat on a state-controlled arterial road, which meant a separate approval pathway beyond council.
• Mixed-use fit-outs. At Multiple Electrical Services, a raw 600 m² factory needed a multi-use facility approved by council, and the project secured fast-track council approval.

These are examples of site-specific issues, not a promise about any future approval. Your certifier decides what your site requires.

Industrial areas across Queensland

Whether your business sits in the industrial areas of Brisbane, the Gold Coast or the Sunshine Coast, the process above is the same. What changes is the building age, the zoning and the council. Our Brisbane location page lists the areas we work in.

Getting your documents ready

To keep the certifier's assessment moving, gather these before you lodge:

• The existing building's approved plans, if available
• A clear description of the intended use and loading
• Site and slab information
• Engineered mezzanine drawings
• Details of stairs, handrails and any pallet gates
• Contact details for the owner, and the landlord if you lease

If you lease the premises, owner consent will also come into play, and our post on mezzanine approval for leased warehouses covers that side.

FAQs

Do I apply to council or to a private certifier?

You apply through a building certifier, who can be private or employed by a council. Brisbane City Council, for example, states that building approval from a private certifier is required before final building certification. Your certifier will tell you how lodgement works in your council area.

Can I use the mezzanine as soon as it is built?

No. A certificate of occupancy is required before a class 5 to 9 building, such as most commercial and industrial buildings, is used or occupied after building work. The certifier issues it once they are satisfied.

Is a small mezzanine exempt from approval?

Do not assume so. Building work needs a building development approval unless it is accepted development under the Building Regulation 2021. Your certifier should confirm in writing whether your mezzanine falls under an exemption.
