One of the most common points of confusion for anyone building, extending, or renovating a house in Victoria is understanding the difference between a Planning Permit and a Building Permit. Many homeowners mistakenly think they only need one or the other.
In Victoria, these two permits are governed by entirely different laws, serve different purposes, and are assessed by different professionals. Here is the ultimate breakdown to keep your project legally compliant.
| Feature | Town Planning Permit (Planning) | Building Permit (Building) |
|---|---|---|
| What is it? | Consent for the land use and development. It looks at what you want to build and where. | Permission for the physical construction to begin. It looks at how it will be built. |
| Governed By | Planning and Environment Act 1987 & Local Council Planning Schemes. | Building Act 1993 & National Construction Code (NCC). |
| Approved By | Your local Municipal Council. | A Registered Building Surveyor (RBS). |
| Focus Area | Neighbourhood character, character overlays, privacy (ResCode), and environmental impact. | Structural safety, fire protection, energy efficiency, and construction compliance. |
| Timeline | Must be obtained first (if triggered). | Obtained second, using the endorsed planning plans. |
1. When do you need a Town Planning Permit?
A Planning Permit is not always required for every home. It is "triggered" by the specific rules of your land's zone or overlays. You will generally need one if:
- Small Lot Size: Your parcel of land is under a certain threshold – most commonly smaller than 300m² or 500m² (depending on your local council's schedule).
- Land Overlays exist: Your block is subject to special overlays such as a Character Overlay (preserving historic character), Bushfire Management Overlay (BMO), or Special Building Overlay (SBO) for flooding areas.
- Double-Storey / Multi-Dwellings: Building multiple homes on one lot (units/townhouses) or building a new double-storey house that breaches local ResCode standard setbacks.
2. When do you need a Building Permit?
A Building Permit is 100% mandatory for almost all structural building works in Victoria to ensure the building is safe to occupy. You need one for:
- Building any new house or major extension.
- Constructing structurally significant smaller additions, such as a closed Garage, a large Carport (over 10m²), or a large covered verandah.
- Any structural alterations, demolitions, or safety changes to an existing home.
