Zoning and Planning Overlays in Victoria: A Buyer's Guide
The zoning and planning overlays on a Victorian property affect what you can build, renovate, or use the land for. Here's how to read the planning certificate in your Section 32.
Most buyers focus on the price and the building. But the planning certificate inside the Section 32 can have a significant impact on what you're able to do with the property — both now and in the future. Here's how to read it.
What is zoning?
Zoning is a planning control that divides land into categories based on its intended use. In Victoria, zoning is set out in each council's planning scheme — a document administered by the council but governed by the state government's Victorian Planning Provisions. Changes to zoning require a formal planning scheme amendment approved by the Minister for Planning.
Common residential zones in Victoria include:
- Neighbourhood Residential Zone (NRZ) — the most restrictive; limits development to protect existing neighbourhood character. Maximum building height typically 8–9 metres.
- General Residential Zone (GRZ) — allows medium-density development with council approval.
- Residential Growth Zone (RGZ) — encourages higher-density development; allows taller buildings.
- Mixed Use Zone (MUZ) — allows a combination of residential and commercial uses.
- Township Zone — applies in rural and regional Victoria.
Zoning directly affects how many dwellings can be built on a lot, whether you can subdivide, and what height limits apply. If you're buying with subdivision or development in mind, the zone is critical.
What are planning overlays?
Overlays are additional planning controls that sit on top of the zone. A property can have one overlay, several overlays, or none. Unlike zoning, which determines the broad use of land, overlays apply specific rules to manage particular issues or characteristics.
Common overlays in Victoria
- Heritage Overlay (HO) — applies to properties with heritage significance. Requires council approval for most external changes, including painting, demolition, and extensions. Applies to many inner-Melbourne and established suburb properties.
- Vegetation Protection Overlay (VPO) / Significant Landscape Overlay (SLO) — protects significant trees and landscapes. May require a permit to remove trees on the property.
- Design and Development Overlay (DDO) — sets specific design requirements, such as height limits or setbacks, often in areas near activity centres.
- Flood Overlay (LSIO / SBO) — indicates land subject to flooding. Affects insurance and may restrict what can be built.
- Bushfire Management Overlay (BMO) — applies to properties at risk of bushfire. Imposes construction standards and may require a Bushfire Attack Level (BAL) assessment.
- Environmental Audit Overlay (EAO) — indicates potential land contamination; an environmental audit may be required before development.
How do I find out what zone and overlays apply?
The planning certificate attached to the Section 32 lists the zone and all overlays. You can also check the council's planning scheme or use Planning Maps Online (the Victorian government's free mapping tool) to view zoning and overlays for any property.
What questions should I ask?
- What zone is the property in, and how does it affect what I can build?
- Are there any overlays, and what do they restrict?
- If there's a Heritage Overlay, what changes require a permit?
- If there's a vegetation overlay, can I remove any trees?
- Does the zoning allow me to subdivide if I want to in the future?
