Do I Need Council Approval to Renovate in Queensland?

Quick answer: most cosmetic renovations in Queensland - new kitchens, bathrooms, flooring, painting, joinery and like-for-like repairs - do not need council approval. You generally need building approval once you change the structure, alter the building's footprint or height, remove a load-bearing wall, build a deck over 1 metre high, or convert a garage into a habitable room. Development approval from council is a separate step and is usually only triggered by planning overlays such as character housing, heritage, flood or coastal controls.

The two approvals people confuse

Queensland has two separate approval systems and almost every argument on a job site comes from mixing them up. Building approval (BA) is about how the work is built - structure, fire, waterproofing, glazing, energy efficiency - and it is assessed against the National Construction Code and the Queensland Development Code. Development approval (DA) is about whether the work is allowed on that land at all, and it is assessed against the local planning scheme, which on the Gold Coast is the City Plan and in Brisbane is the Brisbane City Plan.

A straightforward rear deck on a suburban Robina block may need building approval and no DA at all. A modest front-facing change to a pre-1946 Brisbane cottage in a character overlay may need a DA even though the building work itself is minor. Same state, different triggers.

Renovations that usually need no approval

• Replacing a kitchen in the same footprint, with no wall removal and no new plumbing outside the existing wet-area zone
• Bathroom refits where the room stays the same size and the waterproofing is redone to AS 3740 by a licensed waterproofer
• New flooring - hybrid, timber, tile or carpet - over an existing subfloor
• Painting, rendering, skirting, architraves, internal doors and built-in joinery
• Replacing a like-for-like roof covering, gutters and downpipes
• Low decks and landings under 1 metre above natural ground level (still check the planning scheme and any pool-barrier implications)
• Non-structural plasterboard and ceiling repairs

Note the phrase 'no approval' does not mean 'no rules'. Waterproofing, electrical, plumbing, glazing and termite management still have to comply and still have to be done by licensed trades. Exempt work that fails inspection at sale time is a very expensive way to save a certifier's fee.

Renovations that almost always need building approval

• Removing or altering a load-bearing wall, including inserting a steel or LVL beam
• Any home extension, room addition, second-storey addition or building in under an existing high-set house
• Converting a garage, carport or under-croft into a habitable room
• Decks, verandahs and stairs more than 1 metre above ground, or any structure attached to the house that changes its structural load path
• New window or door openings in a load-bearing wall
• Carports, garages, patios, pergolas with a roof, and most shade structures
• Re-stumping, re-blocking or raising a Queenslander
• Any change that alters the building's classification - for example creating a dual occupancy or a secondary dwelling

What a private building certifier actually does

In Queensland you do not lodge building approval with the council in most cases. You engage a private building certifier, who assesses the drawings, issues the approval, carries out mandatory inspections at set stages and issues the Form 21 final certificate at the end. Council still gets a copy for its records. A competent builder will have certifiers they use regularly, and part of our job at Orange Projects is coordinating that whole chain so the homeowner is not chasing paperwork.

1. Concept and measured drawings prepared
2. Engineering (RPEQ) certificates prepared where structure is affected
3. Certifier assesses and issues building approval
4. Stage inspections - footings, frame, waterproofing, final
5. Form 21 final certificate issued and filed

Planning overlays that catch Gold Coast and Brisbane owners out

Overlays are the reason two identical renovations get different answers. The ones we hit most often across South East Queensland are the character residential overlay in Brisbane's inner suburbs, flood hazard overlays along the Nerang and Brisbane rivers, coastal erosion and storm-tide overlays through Palm Beach, Mermaid Beach and Paradise Point, and height or setback controls on canal-front blocks in Broadbeach Waters and Hope Island.

Check the property report on your council's mapping tool before you commission drawings. Ten minutes there can save a design that has to be redrawn twice.

How long approvals take

For straightforward work, building approval through a private certifier is typically returned in one to three weeks once the drawings and engineering are complete. A code-assessable development application through council is commonly six to twelve weeks. Impact-assessable applications, which include public notification, run considerably longer. Build the approval window into your program before you commit to a start date - it is the single most common source of frustration in renovation timelines.

What happens if you skip approval

Unapproved building work does not quietly disappear. It surfaces during a sale, during a refinance, or during an insurance claim - which is the worst of the three. Councils can issue enforcement notices requiring the work to be certified retrospectively or removed. Retrospective certification means opening up finished work so a certifier can see what is behind it, so a job that would have cost a few thousand in fees becomes a demolition exercise. Insurers can also decline claims connected to unapproved structural work.

Checklist before you start any Queensland renovation

1. Write down exactly what is changing structurally, not just cosmetically
2. Pull your council property report and note every overlay
3. Confirm whether the home was built before 1990 (asbestos) or 1946 (character controls in Brisbane)
4. Ask your builder in writing who is engaging the certifier and who pays the fees
5. Confirm the QBCC licence class of whoever is doing the work and check the licence on the QBCC register
6. Make sure home warranty insurance is included where the contract value requires it
7. Keep every approval, engineering certificate and Form 21 in one folder for resale
