If a branch falls, roots crack a path, or a street tree starts leaning after a storm, one question comes up fast: who is responsible for tree damage?
In Sydney, the answer depends on where the tree stands, who owns or controls that land, whether the risk was known, and what steps were taken before the damage happened. For homeowners, strata committees and property managers, that can feel hard to sort out. For councils, the issue often sits inside public safety, inspection programs and asset management.
This guide explains how responsibility usually works on private land, strata land and public land in NSW. It also covers overhanging branches, neighbour disputes, insurance, negligence and the role of arborist reports. The aim is simple: help you work out your next step before a minor issue turns into property damage, a formal dispute or a safety event.
If you’re unsure where responsibility sits, request a neutral arborist opinion.
Key Takeaways
- Who is responsible for tree damage usually starts with ownership or control of the land where the tree stands.
- On strata sites, the owners corporation usually handles trees on common property. Lot owners usually handle trees within their own lot space.
- Overhanging branches are not a free-for-all. In many Sydney council areas, pruning still needs council approval, even when branches cross the boundary.
- Street and footpath trees are commonly managed by council, though private owners may still be responsible if a private tree encroaches into public clearance space.
- Storm damage does not automatically mean the tree owner pays. A key issue is whether there was known risk and whether reasonable action was taken.
How Responsibility Works on Private, Strata and Public Land
Private Residential Land
On private land, the owner is usually responsible for maintaining trees on that land. If a neighbour’s tree causes damage, photos, repair quotes and an arborist report are useful early steps. On owner-occupied blocks, residential tree services can help document condition, identify risk and set out practical next steps.
That does not mean every tree failure leads to automatic liability. A tree can fail in extreme weather with no clear warning signs. In that setting, the issue often shifts to condition, prior notice, maintenance history and expert evidence.
Common Private-Land Examples
- A dead limb drops from your own tree onto your garage roof
- Roots from a neighbour’s tree damage a fence or driveway
- A leaning tree shows decay, then fails after heavy wind
- A tree near a retaining wall creates movement in soil or paving
In each case, records matter. Photos, dates, written notice, past pruning, previous advice and council approvals all help show what was known and what action was taken.
Strata Property
Strata adds one more layer. In NSW, the owners corporation is responsible for maintenance and repair of common property, and owners are responsible for items within their own property. For committees and managers dealing with recurring pruning, access and compliance issues, a strata tree management guide can help frame the issue before formal advice is sought.
The NSW common property memorandum goes further. It says the owners corporation is responsible for that part of a tree which exists within common property, and the lot owner is responsible for that part of a tree within the cubic space of a lot.
Public Land and Council-Managed Trees
Where the tree stands on public land, the managing public authority usually leads. Street trees are often protected and maintained through council tree maintenance programs.
That gives a useful working rule:
Quick Way to Think About It
- Private block: owner usually leads
- Strata common property: owners corporation usually leads
- Street tree or park tree: council or public authority usually leads
If you need a formal, neutral view before you write to a neighbour, insurer, strata manager or council, arrange an arborist assessment.
Overhanging Branches and Boundary Disputes
Can You Cut Branches Back to the Boundary?
Many people assume yes, with no paperwork. In NSW, that can be risky.
If a neighbour’s tree has overhanging branches, it is wise to speak to your neighbour and check with your local council before cutting back to the boundary. Some trees are protected and permission may be needed. You should not enter the neighbour’s land without permission. If the work may involve pruning or removal on a protected site, it helps to understand how to get council approval for tree removal before booking works.
Some Sydney councils require permission to prune overhanging branches from a neighbour’s tree, even when those branches cross the boundary.
What Councils Usually Will Not Do
A lot of owners expect council to force the neighbour to act. In many private tree disputes, that does not happen. Disputes often need to be discussed between neighbours first, then moved to mediation or court if needed.
When the Land and Environment Court Becomes Relevant
The Trees (Disputes Between Neighbours) Act 2006 provides a process for resolving disputes about tree and hedges on a neighbour’s land. A person can apply for orders for pruning, removal or compensation for damage.
That is a pre-legal turning point. Before it gets that far, an arborist report often helps narrow the issue to facts:
- Tree location
- Species
- Structural condition
- Visible defects
- Likely risk level
- Branch or root spread
- Whether work is urgent
- Whether the problem appears to be damage, nuisance, or a safety risk
Quick Reference Table by Scenario

|---|---|---|
|
Private tree damages owner’s own house |
Property owner |
Tree condition, insurer terms, maintenance history |
|
Neighbour’s branches overhang your yard |
Affected neighbour starts, owner of tree stays involved |
Council approval, protected tree status, access rights |
|
Roots damage shared fence |
Both neighbours may be involved |
Cause of damage, fence location, arborist evidence |
|

Owners corporation |
Common property duty, urgency, contractor records |
|
Tree part sits within lot cubic space in strata |
Lot owner for that part |
Strata plan, by-laws, tree location |
|
Street tree blocks signs or drops deadwood |
Council or public authority |
Inspection, hazard reporting, maintenance program |
|
Private tree extends into public clearance space |

Encroachment into road or footpath clearance |
This table is a guide. Site facts still matter.
If the facts are mixed, ask for a neutral arborist opinion before the issue hardens into a dispute.
Footpath and Street Trees – When Council Takes the Lead
Street Trees Are Usually Public Assets
For street and footpath trees, councils often run the inspection, pruning and removal program. Street trees are usually pruned for safety, clearance and tree health, not for private views or minor nuisance such as leaf drop.
Why Councils Take a System-Based Approach
Public-tree responsibility is tied to scale. Councils manage large street-tree networks and use inspection cycles, work priorities and risk thresholds rather than acting on each complaint in isolation.
Why This Issue Is Getting More Attention
Recent state and insurance reporting shows severe weather events and storm-related claims remain a major issue across NSW and Australia. That makes documentation and early hazard assessment more important for owners, strata and councils.
Insurance, Negligence and Documentation
Insurance Does Not Decide Legal Responsibility on Its Own
Insurance may cover part of a loss. It does not settle every question about fault.
If a neighbour’s tree falls on your property during a storm, the neighbour may not be responsible unless they were aware the tree was in a dangerous condition. That makes negligence a live issue. A known defect, visible decay, prior notice, ignored expert advice or repeated complaints can all matter.
The Documents That Carry Weight
For Homeowners
- Dated photos before and after the event
- Storm date and weather records
- Any earlier messages to the neighbour
- Council correspondence
- Repair quotes
- Arborist report
For Strata
- Strata plan and by-laws
- Maintenance requests
- Committee minutes
- Contractor scope
- Emergency work invoices
- Arborist report tied to common property or lot space
For Councils and Public Assets
- Inspection history
- Defect reports
- Response time records
- Pruning history
- Resident complaint records
- Traffic or pedestrian risk notes
A short paper trail is far better than no paper trail.
If you need to show urgency, a neutral arborist report can identify visible defects, likely targets, risk level and work priority in clear terms.
When to Involve an Arborist for Formal Advice
Early Advice Can Stop a Legal Problem From Growing
A neutral arborist opinion is useful when:
- Ownership or control is unclear
- A neighbour dispute is building
- Strata is unsure if the tree sits on common property
- The council has asked for expert input
- An insurer wants evidence
- There is visible decay, lean, cracking, root lift or branch failure
- The matter may move to mediation or court
What a Formal Arborist Opinion Can Cover
- Tree identification and location
- Ownership and control clues
- Structural condition
- Observed defects
- Likely risk to people or property
- Management options
- Urgency of works
- Whether further engineering, legal or council review may be needed
That kind of report helps move the discussion from opinion to evidence.
If you’re unsure where responsibility sits, request a neutral arborist opinion.
Final Words
Tree responsibility in Sydney is rarely settled by one simple rule. The land title matters. The strata plan matters. Council controls matter. Weather history matters. Records matter.
For private owners, the starting point is usually the tree owner’s duty to maintain their tree. For strata, the split often sits between common property and lot space. For footpath and street trees, the public authority commonly leads. Overhanging branches and boundary disputes sit in a separate lane again, with council controls and court processes in the background.
The practical move is to sort out the facts early, keep records, and get expert advice before damage, delay or conflict gets worse.

Frequently Asked Questions
Know more about us
Who is responsible if my neighbour’s tree damages my property?
Responsibility depends on more than where the damage landed. A key question is whether the neighbour owned or controlled the tree and whether there were signs of risk before the damage happened. If the tree looked sound and failed during severe weather, liability may not be clear. If there were visible defects, past complaints or ignored advice, that may affect responsibility.
Can I cut back branches from a neighbour’s tree in Sydney?
Sometimes, though you should not assume you can do the work without checking first. In many Sydney council areas, pruning may need approval, especially if the tree is protected. You should speak with your neighbour, check local council rules and avoid entering the other property without permission.
Who looks after trees in a strata complex?
In many cases, the owners corporation is responsible for trees on common property, and lot owners are responsible for trees or parts of trees within their own lot space. The strata plan, by-laws and the exact tree location matter. If the boundary is unclear, an arborist assessment can help support the next step.
Is council responsible for footpath or street tree damage?
If the tree is on public land, council or another public authority will usually manage inspection, pruning and removal. That said, private owners may still need to act if a privately owned tree extends into public clearance space or creates risk near roads or footpaths. The first step is to confirm where the tree stands and who controls that land.
When should I get an arborist report for a tree dispute?
It is worth getting an arborist report when ownership is unclear, damage has already occurred, a neighbour dispute is building, or an insurer, strata manager or council needs formal evidence. A report can document tree condition, visible defects, likely risk and recommended action in a neutral format.
