Who pays for neighbour tree root damage in NSW?
When a neighbour’s tree roots damage your pipes, driveway, or foundations in NSW, who pays? The answer depends on liability, negligence, and the Trees (Disputes Between Neighbours) Act 2006. This 2025 guide explains the law, real cases, and how to claim costs fairly.
1) Introduction & Overview
Hook: In NSW, if a neighbour’s tree roots damage your property, the general rule is the owner of the tree may be liable — but only if negligence or unreasonable encroachment can be proven.
Who this is for: Homeowners, strata managers, and tenants facing neighbour tree root damage responsibility in NSW.
Credentials: Based on NSW Land and Environment Court cases and arborist expertise from Triple T Tree Services – Tree Removal Sydney.
Testing period: Research updated with 2025 case precedents, including Jones v Ruthven (2024) and NSW Civil Tribunal records.
2) Liability & Legal Framework (Specifications)
| Scenario | Who Pays | Relevant Law / Rule |
|---|---|---|
| Tree roots cross boundary & damage sewer line | Tree owner (if negligent) | Common law nuisance + Trees (Disputes Between Neighbours) Act 2006 |
| Natural tree growth without negligence | Affected homeowner | Each party bears own cost unless negligence proven |
| Tree on council land | Local council | Council liability under Local Government Act s43 |
| Boundary tree jointly owned | Shared responsibility | Equal contribution to removal or remedial work |
3) How Root Damage Happens (The “Design & Build”)
Tree roots naturally seek moisture, often invading drains, retaining walls, or driveways. The worst offenders are figs, camphor laurels, and paperbarks — all common across Sydney suburbs.
- Materials & Construction: Older clay pipes and shallow foundations are more vulnerable.
- Ergonomics: Tree roots can travel over 20m underground from the original tree base.
- Durability: Roots exert enough force to lift concrete slabs over years.
4) Who Pays & Why (Performance Analysis)
4.1 Core Functionality
The question of “who pays for tree root damage” in NSW depends on fault, foreseeability, and reasonableness. Courts assess:
- Whether the tree owner knew or should have known roots were causing damage.
- If reasonable steps (like pruning or root barriers) were taken.
- Extent and cost of the resulting damage.
4.2 Key Performance Categories
- Negligence: Failure to maintain or inspect trees near property boundaries.
- Nuisance: Roots interfering with neighbour’s enjoyment or use of land.
- Damage quantification: Expert arborist and engineer reports used in court.
5) Real Homeowner Experiences (User Experience)
Setup: Many homeowners first notice plumbing blockages or cracks before discovering tree roots are responsible.
Daily use: Affected owners must document evidence: CCTV drain footage, repair invoices, and arborist opinions.
Learning curve: Moderate — legal terms like common law nuisance and root encroachment neighbour liability need explaining by professionals.
6) Council vs Private Responsibility
| Tree Owner | Responsibility | Who to Contact |
|---|---|---|
| Private neighbour | Liable for proven damage or nuisance | NSW Civil and Administrative Tribunal (NCAT) |
| Local council | Liable if damage caused by public tree negligence | Council tree management team |
| Shared / strata tree | Joint financial responsibility | Body corporate or strata manager |
