If you're planning a renovation, one of the first questions you should ask is whether council approval is required.

The answer depends on the type of work, the location of your property, and whether your home is affected by planning overlays such as heritage, flood, bushfire, or environmental controls.

Approval pathways vary between states and local councils, but the core principles remain similar across Australia.

‍

Renovations That Usually Do NOT Require Council Approval

Some minor works may not require development approval, particularly if they fall under exempt or complying development provisions.

Examples can include:

• Internal renovations that do not affect structure
• Replacing kitchen or bathroom fixtures
• Cosmetic updates such as painting or flooring
• Like-for-like window replacements

However, even internal works may require building approval if structural elements are modified.

‍

Renovations That Often DO Require Approval

The following types of projects commonly trigger council or building approval:

1. Extensions or Additions

Any increase in floor area, new rooms, decks, or raising a house generally requires assessment.

2. Structural Changes

Removing load-bearing walls or altering roof structure will typically require building approval and structural certification.

3. Heritage or Character Properties

If your home is located within a heritage or character overlay, external changes may be restricted or subject to additional review.

4. Flood, Bushfire or Environmental Overlays

Properties in flood-prone, bushfire-prone, coastal, or environmentally sensitive areas may require additional reporting and compliance measures.

5. Secondary Dwellings or Granny Flats

Secondary dwellings almost always require assessment against local planning codes and building regulations.

Building Approval vs Development Approval

It’s important to understand the difference between these two common approval types.

‍

Building Approval

Required for structural safety and compliance with the National Construction Code (NCC).
This ensures the project meets minimum safety, health, and performance standards.

‍

Development Approval

Required when a proposal conflicts with local planning scheme requirements, zoning rules, or overlays.
This approval is issued by your local council.

Some projects require both building and development approval.

How to Check If Your Property Has Overlays

To determine what applies to your property, you can:

• Search your local council’s planning scheme online
• Review zoning and overlay maps
• Request a planning certificate or property report
• Engage a town planner or architect early

Older suburbs and established neighbourhoods often contain heritage or character controls, while coastal and regional areas may include additional environmental overlays.

‍

What Happens If You Build Without Approval?

Undertaking assessable development without approval can result in:

• Stop work notices
• Fines or penalties
• Retrospective approval costs
• Delays in construction
• Issues when selling the property

Obtaining clarity before construction begins significantly reduces risk.

‍

When to Seek Professional Advice

If your renovation involves structural changes, extensions, or alterations to the external appearance of your home, professional advice is strongly recommended.

Early design advice can:

• Clarify approval pathways
• Reduce redesign costs
• Improve compliance outcomes
• Avoid delays during construction

Engaging professional guidance early in the process often saves time and money later.

Final Thoughts

Not all renovations require council approval in Australia, but many do once structure, floor area, or planning overlays are involved.

Before committing to demolition or construction contracts, confirm your approval requirements. It is significantly easier and more cost-effective to resolve compliance matters before work begins.
