Do I Need a Council Permit to Remove a Tree on the Northern Beaches?

It's one of the most common questions I get asked on site: "Do I actually need council approval to take this tree down, or can I just get it done?" The honest answer is: it depends — but if the tree is of any significant size on the Northern Beaches, the answer is almost always yes, you need to check first.

Northern Beaches Council (NBC) protects trees under its Development Control Plan (DCP), and the rules apply right across the LGA — from Manly and Dee Why in the south to Mona Vale and Avalon in the north. Getting it wrong isn't just a bureaucratic inconvenience — the fines are serious and the council can order you to restore what you removed at your own expense.

This guide walks you through exactly what Northern Beaches Council requires, which trees are exempt, how the application process works and how The Living Canopy can help you navigate it without the headaches.

What Does the Northern Beaches Council DCP Say?

Northern Beaches Council's DCP sets out clear size thresholds that trigger the need for approval before any tree work — pruning, lopping or removal. A tree requires council consent if it meets any one of the following criteria:

• Height: the tree is 5 metres or more in height
• Canopy spread: the tree has a canopy spread of 5 metres or more in diameter
• Trunk diameter: the trunk measures 30 cm or more in diameter when measured at 1 metre above ground level

If your tree meets any one of these thresholds, you need approval before touching it. Note that this applies to both removal and significant pruning — so even if you're only planning to remove major limbs, the same rules apply if it meets the size thresholds.

It's also worth knowing that some properties — particularly those with heritage listings or those carrying a Biodiversity Conservation Act listing — may have additional obligations on top of the standard DCP rules. If your property backs onto bushland or is in a sensitive area like parts of North Narrabeen or Narrabeen near the lagoon, it's worth double-checking with a qualified arborist before assuming the standard rules apply.

Which Trees Are Exempt?

Not every tree requires council approval, even if it's over the size thresholds. There are several situations where you can proceed without a permit — but you need to be careful, because the exemptions are specific and some require documentation.

Dead Trees

A tree that is genuinely dead — with no live tissue remaining in the trunk, branches or root system — is generally exempt from the permit requirement. However, "dead" needs to be verified by a qualified arborist before you proceed. Council expects you to be able to demonstrate the tree was dead at the time of removal if they follow up. A letter or report from a certified arborist on file is the right way to protect yourself here.

Be careful with trees that appear dead but aren't. Some species — particularly natives — can look completely bare and dry in drought conditions but flush again after rain. Don't assume.

Trees Within 3 Metres of an Approved Structure

Trees with a trunk (measured at ground level) within 3 metres of an approved structure — such as a dwelling, garage or outbuilding — may be exempt in certain circumstances. This exemption exists to allow homeowners to remove trees that genuinely pose a structural threat. However, the structure must be an approved one (shown on council-approved plans), and the exemption doesn't apply to trees listed as significant or protected species.

Genuine Emergencies

If a tree has been damaged in a storm and poses an immediate danger to people or property, emergency work can proceed without prior consent. This is what's covered when a tree comes down in a storm and is blocking your driveway at 11pm on a Sunday. The work must be limited to making the situation safe — it doesn't cover removing a healthy tree because it "might" cause problems in future. We cover this scenario in more detail in our guide to storm damage and fallen trees.

Certain Species

Noxious weeds and declared invasive species can generally be removed without a permit regardless of size. This includes things like Camphor Laurel (Cinnamomum camphora) in some contexts, though it's worth checking — NBC has its own schedule. Fruit trees planted deliberately for domestic use are also typically exempt.

How to Apply for a Tree Removal Permit

The good news is that Northern Beaches Council's application process is now entirely online, which makes it more straightforward than it used to be.

The Online Portal

Applications are submitted through NBC's online services portal. You'll need to create an account if you don't already have one. The application requires:

• Your property address and lot/DP details
• The species, size and location of the tree(s) you want to work on
• Your reason for the application (removal, pruning, etc.)
• Photos of the tree from multiple angles, including the base and any damage or defects
• A site plan showing the tree's location relative to structures and boundaries
• Supporting arborist report (required in most cases — see below)

The Application is Free

One thing many people don't know: the application itself costs nothing. There is no fee payable to Northern Beaches Council to apply for tree removal consent. The cost comes from the arborist report you may need to commission — but the council assessment itself is free.

How Long Does It Take?

NBC's standard assessment period is 40 business days from lodgement. That's around two months in real time. This is worth factoring into your planning — if you need a tree removed before building works begin, you need to lodge well in advance. Don't make the mistake of booking a tree removal crew before you have consent in hand.

In practice, some straightforward applications — a clearly dead tree, a small removal with no heritage or ecological issues — can come back faster. But 40 business days is the benchmark to plan around.

Do You Need an Arborist Report?

For most applications, yes. An arborist report from a qualified and certified arborist substantially strengthens your application and is often the difference between approval and refusal. Council officers are more willing to approve a removal when a professional has assessed the tree and provided an objective opinion on its condition, risk, amenity value and likely response to management alternatives.

An arborist report for a permit application typically covers:

• Species identification and size measurements
• Tree condition assessment (health, structure, defects)
• Risk assessment — including target assessment (who or what is at risk)
• Whether management alternatives (pruning, cabling, monitoring) could mitigate the risk
• Recommendation for or against removal
• Any replanting recommendations

At The Living Canopy, Alex holds a Certificate IV in Arboriculture and can provide arborist reports suitable for NBC permit applications. These are written to the Australian Standard for tree assessment (AS 4373) and are submitted in a format council assessors are familiar with.

What Happens If You Remove a Tree Without Consent?

This is where people get into serious trouble. Removing a tree without council approval on the Northern Beaches — where one is required — is a breach of the Environmental Planning and Assessment Act 1979. The consequences can be significant:

• Fines: on-the-spot penalty notices can be issued to both the property owner and the contractor. Fines for individuals run into the thousands of dollars and are higher for corporations or developers.
• Restoration orders: council can issue an order requiring you to replant — not just one replacement tree, but potentially multiple trees and associated works at your own cost.
• Court proceedings: in serious cases, particularly where a significant or heritage tree is involved, the matter can be referred to the Land and Environment Court, where penalties are substantially higher.

The "I didn't know" defence carries very little weight with council. The rules are publicly available, and the council's view is that it's the property owner's responsibility to check before proceeding.

This isn't just an issue in suburbs with older tree canopies like Manly or Dee Why. Properties right across the Northern Beaches — including newer estates in Mona Vale and Avalon — fall under the DCP rules.

How The Living Canopy Helps

Navigating council rules is one of the more frustrating parts of owning a property on the Northern Beaches. We help clients through the process in a few different ways:

Initial Assessment

Before you spend any money, we'll come to your property and give you an honest assessment of whether your tree actually needs council approval, whether it might qualify for an exemption, and what outcome you're likely to get if you apply. There's no point lodging an application for a tree council is very likely to refuse — but equally, there's no point paying for a report if the tree turns out to be exempt.

Arborist Reports for Applications

Where an arborist report is needed, we prepare one that's written clearly for a council audience. We've dealt with NBC assessors regularly and we know what they're looking for. A well-prepared report that addresses the right criteria makes the assessment process much smoother and gives your application the best chance of approval.

End-to-End Support

If you'd prefer not to deal with the portal yourself, we can guide you through the application step by step or assist with lodging supporting documentation. Once consent is granted, we carry out the tree removal and handle debris removal and site cleanup — so the whole job is handled by one team.

We work across the whole Northern Beaches, including North Narrabeen, Narrabeen, Dee Why, Manly, Mona Vale and Avalon.
