Expert Arborist Reports Across Inner West Council

Inner West combines dense terrace and semi-detached housing with ongoing townhouse and apartment redevelopment across the former Ashfield, Leichhardt and Marrickville council areas.

Mature street and private trees on tightly built blocks mean Arborist Reports are frequently required for extensions, renovations and construction near retained trees. Development projects can also require Tree Protection Plans and Project Arborist involvement where building works interact with established trees.

Arbor Express prepares Council-ready AQF Level 5 Arborist Reports accepted by Inner West Council and the NSW Planning Portal for Development Applications, Complying Development, tree removal permits and tree risk assessments.

Services are available throughout Annandale, Ashfield, Balmain, Camperdown, Croydon, Dulwich Hill, Leichhardt, Lilyfield, Marrickville, Newtown, Petersham, Rozelle, Stanmore, Summer Hill and surrounding Inner West suburbs.

Which Arborist Report Do You Need?

Extensions, dual occupancies and townhouse or apartment developments are common reasons property owners across Inner West need a DA Arborist Report. Mature trees on constrained inner-city blocks can also trigger Tree Protection Plan requirements or Project Arborist involvement during construction.

DA Arborist Reports (AIA)

For Development Applications and Complying Development across the Inner West, we assess trees that may be affected by proposed building works and document their health, structural condition and suitability for retention.

Reports can include Tree Protection Zone and Structural Root Zone mapping in accordance with AS 4970, providing the arboricultural documentation required for Council or NSW Planning Portal lodgement.

icon

Health & Safety Tree Assessments

Where a tree is showing signs of decay, structural weakness, dieback or potential instability, our AQF Level 5 Arborists can assess its condition using recognised QTRA and TRAQ tree risk methodologies.

Findings provide professional evidence of the tree's condition and risk, with documentation suitable for property owners, insurers and Council.

icon

Dangerous Tree Removal

Where a tree presents an immediate safety concern, we provide urgent inspections and AQF Level 5 documentation to support Inner West Council's imminent-risk requirements.

The assessment records the condition and identified risk so the appropriate Council pathway can be followed.

icon

Tree Removal & Major Pruning Reports

Protected and prescribed trees requiring Council approval can be professionally assessed to establish their health, structural condition and suitability for retention or removal.

Arbor Express prepares supporting reports for Tree Works Permit applications, including recommendations for major pruning where required, with pruning assessments undertaken in accordance with AS 4373.

icon

Development Compliance & Project Arborist Services

Following Development Consent, Arbor Express can assist with Tree Protection and Management Plans, construction monitoring and Project Arborist supervision to satisfy conditions relating to retained trees.

Additional investigation and consulting services include Tree Root Investigation using AirSpade, Resistograph® testing and ecology reporting for development sites, schools and other properties where more detailed assessment is required.

Inner West Council Tree Management Rules

Inner West Council manages tree removal and pruning under its Tree Management Development Control Plan, in accordance with the State Environmental Planning Policy (Biodiversity and Conservation) 2021. Council consent is generally required before clearing a prescribed tree unless the proposed work falls within a specific exemption.

Prescribed Trees

A tree is prescribed if it:

  • Is 4 metres or more in height
  • Has a trunk diameter greater than 150mm at 1.4 metres above ground where the tree is under 4 metres in height
  • Has a canopy spread of 2 metres or more
  • Is a palm or tree fern with a clean stem of 4 metres or more

Approval Pathways

Pruning more than 10% of a canopy or removing a tree on a heritage-listed property, within a Heritage Conservation Area or forming part of an Aboriginal object or place of heritage significance requires a Development Application.

Other prescribed tree work generally requires a Tree Works Permit.

Exemptions

Council consent is not required for certain works, including:

  • Canopy lifting to 2.5 metres
  • Minor pruning of branches under 100mm in diameter, up to 10% of the canopy annually
  • Deadwood removal where there is no habitat value
  • Removal of a tree within 1 metre of a residential dwelling wall on the same lot, except where heritage protections apply
  • Certain species included on Council's declared exempt species list

Imminent Risk

Where a tree presents an imminent risk to human life or property, Council can issue expedited consent. Prior written notification must be supported by photographic evidence and an assessment from a Qualified Arborist (AQF Level 5) using a recognised risk assessment methodology such as TRAQ or QTRA.

Replacement Planting

Where a prescribed tree is approved for removal, Council generally requires:

  • At least one replacement tree for properties under 300m²
  • At least two replacement trees for properties over 300m²

Replacement trees are generally required to be planted on the same site where a suitable location is available.

Development Sites

Buildings and additions must maintain sufficient distance from existing trees in accordance with AS 4970 to allow practical tree retention. A security deposit may also be required where development is proposed within the Tree Protection Zone of a public tree.

Understanding these requirements early can help avoid delays and ensure the appropriate Tree Works Permit, Development Application or Arborist Report pathway is followed.

Frequently Asked Questions

Is my tree exempt from Council approval?

Council doesn't require consent for canopy lifting to 2.5 metres, minor pruning of branches under 100mm in diameter up to 10% of the canopy annually, deadwood removal without habitat value or removal of a tree within 1 metre of a residential dwelling wall on the same lot.

Certain declared species, including Privet, Cocos Palm, Coral Tree and Camphor Laurel, are also exempt unless heritage-listed. We can confirm exemption status before you proceed.

Do I need Council approval to remove a tree in Inner West?

In most cases, yes. A prescribed tree is protected if it's 4 metres or more in height, has a trunk diameter over 150mm at 1.4 metres above ground for trees under 4 metres, or has a canopy spread of 2 metres or more. Most prescribed tree work requires a Tree Works Permit.

Does heritage listing affect tree removal in Inner West?

Yes. Removing a tree or pruning more than 10% of its canopy requires a Development Application rather than a Tree Works Permit where the property is a heritage item, listed on Council's heritage trees list, within a Heritage Conservation Area or the tree forms part of an Aboriginal object or place of heritage significance.

Can I remove a tree that's an imminent risk without a permit?

If a tree poses an imminent risk to human life or property, Council can issue expedited written consent. You must first notify Council with photographic evidence and written evidence from an AQF Level 5 Arborist using a recognised risk assessment methodology such as TRAQ or QTRA.

Do I need to replant if my tree removal is approved?

Generally, yes. Council requires at least one replacement tree for properties under 300m² and at least two for properties over 300m², planted on the same site where a suitable location exists.

Do you prepare reports for builders, architects and developers?

Yes. We prepare DA and CDC Arborist Reports at design stage, Tree Protection Plans following approval and Project Arborist inspections throughout construction for residential and commercial projects across Inner West.
