The Garden Area Requirement in Victoria

Victoria's minimum garden area requirement is one of the most decisive controls on what you can build on a residential lot. It reserves a set percentage of your block as garden - and because that percentage rises with lot size, it shapes the footprint, the number of dwellings and the design from the very first sketch. Get it wrong and your plans can be returned; get it right early and the rest of the design falls into place.

The short answer

Victoria's minimum garden area requirement reserves a percentage of a residential lot as garden, scaled by lot size: 25% for lots of 400-500 square metres, 30% for lots above 500 up to 650 square metres, and 35% for lots above 650 square metres. It applies in the General Residential Zone and Neighbourhood Residential Zone. Lots under 400 square metres are exempt.

The detail below explains where the requirement sits in the scheme, exactly what counts, and the exemptions that catch people out.

What the garden area requirement is

The garden area requirement is a mandatory control that says a minimum proportion of a lot must be set aside as garden area when you construct or extend a dwelling or residential building. It sits inside the residential zone provisions - Clause 32.08-4 for the General Residential Zone and Clause 32.09-4 for the Neighbourhood Residential Zone - with the meaning of "garden area" defined in the definitions clause of the planning provisions.

Its purpose is to protect green, permeable, landscaped space as Victoria's suburbs intensify - keeping room for trees, gardens and soft ground rather than allowing lots to be built out wall to wall.

Figure 1: Whether the garden area requirement applies depends on your zone, lot size and whether the works need a permit.

Because the requirement is mandatory, it is not something you can negotiate away with good design - the percentage has to be met (or an exemption has to apply).

The percentage by lot size

The required minimum garden area depends on how big the lot is. The larger the lot, the higher the proportion that must be kept as garden.

Figure 2: The minimum garden area percentage for each lot-size band.

• ✓Lots below 400 sq m - exempt from the requirement for constructing or extending a dwelling
• ✓Lots 400 to 500 sq m - minimum 25% garden area
• ✓Lots above 500 up to 650 sq m - minimum 30% garden area
• ✓Lots above 650 sq m - minimum 35% garden area

So a 520 square metre lot in the General Residential Zone must keep at least 30% of its area - around 156 square metres - as qualifying garden area. That single figure often decides whether a dual occupancy or a larger extension is feasible before any other control is even considered.

These percentages have changed over time, so always confirm the current figures against your own planning scheme rather than relying on a number you read once.

Which zones it applies in

The requirement does not apply everywhere. It is tied to specific residential zones.

• ✓General Residential Zone (GRZ) - applies, under Clause 32.08
• ✓Neighbourhood Residential Zone (NRZ) - applies, under Clause 32.09
• ✓Residential Growth Zone (RGZ) - does not have a minimum garden area requirement
• ✓Other zones - apartment and higher-density development is governed by different standards

The Residential Growth Zone is the key exception many people miss: it is designed for higher-density housing and does not carry a minimum garden area control. Likewise, the garden area percentages are not a Clause 58 apartment requirement - apartment developments assessed under the apartment standards are not subject to the GRZ/NRZ garden area figures unless the land itself is zoned GRZ or NRZ and the proposal falls under those clauses.

We cover the broader rules in what is ResCode in Victoria and the related footprint control in site coverage in Victoria.

What counts as garden area

This is where proposals quietly fail. Garden area is defined as an area on the lot with a minimum dimension of one metre that does not include the dwelling or residential building, a driveway, or an area set aside for car parking. A few small things are allowed within it - for example, eaves up to a limited width, a pergola, unroofed terraces or decks below a set height, a small outbuilding within a modest floor-area limit, and normal domestic services like a clothes line or water tank.

Figure 3: What counts toward garden area, and what is excluded.

The traps that catch people most often: the area under an upper-storey projection or balcony does not count, raised areas only count if they are below the set height limit, and every part has to meet the one-metre minimum dimension to qualify. A thin strip down the side of the house may look like garden on the plan but fail the test. For the exact inclusions, exclusions and dimensions, read the current definition in your planning scheme - the Victorian planning scheme provisions set them out in full.

Exemptions and how to check your lot

Several situations are exempt from the requirement:

• ✓Lots under 400 sq m - exempt for constructing or extending a dwelling
• ✓Designated medium-density sites - lots identified in an approved precinct structure plan, incorporated plan or development plan
• ✓Existing non-compliant buildings - extending a dwelling that did not meet the requirement before the control commenced
• ✓Works that need no planning permit - the requirement is triggered by an application to construct or extend

To check your own lot, confirm your zone and overlays free on VicPlan, note whether you are in the GRZ, NRZ or RGZ, measure your lot area, then read the current garden area provision for your zone. If you are in the RGZ, the requirement does not apply; if you are in the GRZ or NRZ and your lot is 400 square metres or larger, plan your design around the percentage from the start.
