Clause 52.37 canopy trees: a decision tree for builders
Amendment VC289 dropped this into every Victorian planning scheme on 15 September 2025. It can require a planning permit to remove a tree where nothing else would have triggered one, and it has caught a great many projects that were already designed.
What is covered
1. Is your tree a canopy tree?
Three tests, and it must meet all three. Fail any one and the clause does not reach it.
Circumference, not diameter
This trips people constantly. 0.5 m circumference is roughly a 159 mm diameter trunk, which is a small tree. If you read it as diameter you will wrongly conclude that half the trees on your site are exempt.
Measure around the trunk with a tape at 1.4 m. If the tree leans, measure along the stem rather than vertically.
2. Is your site in scope?
The clause applies in these zones:
- Mixed Use Zone
- Township Zone
- Residential Growth Zone
- General Residential Zone
- Neighbourhood Residential Zone
- Housing Choice and Transport Zone
It does not apply in the Low Density Residential Zone, and it does not apply in commercial or industrial zones.
Check the actual zone on VicPlan rather than assuming. Some council summaries of this clause are incomplete: Yarra's published page, for example, names only three of the six zones and omits Residential Growth and Housing Choice and Transport entirely.
3. The boundary tree trap
This is where most people get caught, so read it twice.
If the land is vacant, the clause reaches any canopy tree anywhere on the lot.
If there is an existing dwelling, it reaches only boundary canopy trees. A boundary canopy tree is one with any part of its trunk within:
A boundary canopy tree does not get the exemptions that a canopy tree on an established site would otherwise have.
So the assumption "there is already a house here, so the clause does not apply to me" is right for a tree in the middle of the block and wrong for the same tree three metres off the back fence.
Narrowest street frontage, not front boundary
On a corner lot those are different lines, and the difference decides which trees are caught. Council summaries that say "front boundary" are being loose with it. Banyule's published news item does exactly that.
4. The exemptions
Clause 52.37-8 exempts:
- Emergency and safety works
- Dead trees
- Pruning of trees for maintenance
- Trees identified as weed species
Two notes on the dead tree exemption. It means dead, not declining, and a tree that has dropped its leaves in July is not evidence of anything. Councils have seen the convenient dead tree before. If you are relying on it, have the tree assessed and get the finding in writing.
5. What council may and may not consider
This is the most useful thing on this page and almost nobody writes it down. In deciding a Clause 52.37 application, the responsible authority must consider only the decision guidelines in the clause itself. It cannot reach for state policy, the Municipal Planning Strategy, or local planning policy.
Those guidelines are:
| Guideline | What a good application says about it |
|---|---|
| Canopy contribution and urban heat | What this tree actually contributes, honestly, and what the replacement planting will contribute at maturity |
| Tree health and stability | Assessed by a suitably qualified person, with the defects named rather than asserted |
| Damage to buildings | Evidence, not proximity. A crack near a tree is not a tree causing a crack |
| Design efforts to minimise canopy impact | What you tried. This is the guideline applicants skip, and it is the one that reads worst when it is missing |
| Replacement planting | Species, position, deep soil provision, and what it reaches at maturity |
The practical consequence: an application built around these five points is a different document from a general tree report, and it is considerably shorter. Arguing neighbourhood character or housing policy at a Clause 52.37 decision is arguing something the council is not permitted to weigh.
6. How much replacement canopy you owe
On sites up to 1,000 m² it is a set number of trees by site area. Above that it switches to a canopy cover percentage.
| Site area | Replacement requirement |
|---|---|
| Up to 100 m² | 1 tree |
| 101 to 200 m² | 2 trees |
| 201 to 400 m² | 3 trees |
| 401 to 700 m² | 5 trees |
| 701 to 1,000 m² | 6 trees |
| Over 1,000 m² | Minimum 20% canopy cover of site area |
Replacement trees must be capable of reaching at least 6 m in height and 4 m of canopy at maturity, and they need somewhere to do it:
- Deep soil of at least 12 m² with a minimum dimension of 2.5 m, or
- A planter of at least 12 m³ at a minimum 0.8 m depth
Find this on the plan before you fix the footprint
Six replacement trees each needing 12 m² of deep soil with a 2.5 m minimum dimension is 72 m² of unbuilt, undriven, unpaved ground. On a 900 m² site being developed to its limits, that is a real constraint and it is far cheaper to design around than to retrofit.
Be careful with third party summaries here too. At least one Melbourne consultancy publishes a replacement table showing 10% canopy for sites up to 1,000 m², which does not match the tree count structure in the clause.
7. It does not replace your overlays
Clause 52.37 sits alongside Vegetation Protection, Environmental Significance and Significant Landscape Overlays. It does not override them, and it does not override a local law either.
So a single tree can require:
- A planning permit under Clause 52.37, decided on the five guidelines above, and
- A planning permit under an overlay, decided on that schedule's tests, and
- A local law permit, decided by a different part of the council on a different threshold
Stacking controls is where most applications come unstuck, and the thresholds genuinely do not line up. Boroondara's local law catches trees at 110 cm circumference anywhere on the lot; Clause 52.37 catches trees at 50 cm circumference but only in the boundary strips. A tree can easily be caught by one and not the other. The council pages set out how the two interact in each municipality.
Common questions
When did Clause 52.37 start?
Amendment VC289 introduced it to all Victorian planning schemes on 15 September 2025.
My block already has a house on it. Am I exempt?
Only for canopy trees away from the boundaries. A canopy tree with any part of its trunk within 6 m of the narrowest street frontage or 4.5 m of the rear boundary is a boundary canopy tree and does not get that exemption.
Is 0.5 metres the diameter or the circumference?
Circumference, measured at 1.4 m above ground. That is roughly a 159 mm diameter trunk, so it catches much smaller trees than people expect.
Can I argue neighbourhood character or housing need?
Not usefully. The responsible authority must consider only the decision guidelines in Clause 52.37 itself, and cannot have regard to state policy, the Municipal Planning Strategy or local planning policy when deciding one of these applications.
