A tree question often arrives attached to a second job. A granny flat going up out the back, a driveway being widened, a dual occupancy, a subdivision that needs the yard cleared.
That matters, because a tree tied to building work usually goes down a different path from a tree you simply want gone. Sorting out which one you have is the first thing to do.
Council tree controls and application steps change. Use Blacktown City Council's own current guidance for the address before you rely on anything here. This is general information to help you ask the right questions, not legal or planning advice, and no one can promise you an approval.
First question: is this tree part of a development?
Answer that before anything else, because it decides which door you knock on.
If the tree is inside the footprint of proposed building work — a new dwelling, a secondary dwelling, a pool, a shed, a driveway, a subdivision — the trees are usually dealt with as part of that application rather than as a standalone tree request. Removing them beforehand, on the assumption it will all be approved later, is a bad idea.
If there is no building work involved and you just want the tree dealt with, that is the ordinary tree pathway.
If you are somewhere in between — the plans are not lodged yet, or the tree is just outside the footprint — say so when you ask the council. It is a much better conversation than finding out afterwards.
Describe the work in plain terms
Councils treat different amounts of work differently, so be specific:
- removing the tree entirely
- taking out dead, broken or storm-damaged limbs
- pruning back from a roof, a fence or a boundary
- reducing the height or spread substantially
- clearing several trees or an area of vegetation
- grinding a stump left from an earlier job
"Trimming" is a word that covers everything from a tidy-up to a severe cutback. Describe the amount, not the label.
Then check what is attached to the property
Use the address, not the suburb. A planning certificate for the property is the usual way to see the controls that apply. Look for:
- tree and vegetation provisions in the local planning controls
- any heritage listing or conservation area
- environmental or riparian zoning near creeks and drainage corridors
- bushfire prone land mapping
- existing development consents, including conditions from an earlier approval
- easements and anything registered on the title
Then look at the tree — species, height, trunk size, condition, and whether it stands on your land, a neighbour's, common property or a nature strip.
Trees on a nature strip or in the street
Street trees and nature strip trees may be council-managed even where they sit outside your fence. Ask the council to confirm ownership and the right request path before arranging any work.
If a street tree is the problem, start with a council request. For a tree inside the property, confirm the applicable rules before asking us to quote the work.
Have this ready before you ask
- a photo of the whole tree from a distance
- closer photos of the problem — damage, cavities, lifted roots, the lean
- the trunk and the ground around the base
- where the tree sits in relation to the house, the fence and the boundary
- the way into the yard and anything close by
- a plain description of what you want done and why
- plans, a planning certificate or an existing consent if building work is involved
Photos help us start a quote and help the council understand the request. They are not always enough on their own, and we will tell you if we need to see the tree.
When an independent report comes into it
The council may want an independent arborist report where it needs a professional assessment of the tree or the reason for removal — commonly on larger or established trees, or where a tree is close to proposed building work.
Check the current requirements first, then arrange the report through a suitably qualified independent arborist. Our quote covers the tree work; it is not an arborist report and it does not decide the outcome of an application.
Dead, dangerous and storm-damaged trees
Do not assume a damaged tree can come out with nothing recorded. There is usually a process for urgent work, and it is worth knowing what it is.
Keep clear of a split, hanging or fallen tree. If power lines are involved, contact emergency services or the electricity network first and follow their advice. Photograph what you can from a safe position — the council may want it, and so may your insurer.
Read the conditions, not just the approval
An approval can carry conditions: limits on how much comes off, requirements for how the site is left, or replacement planting with a species, a location and a timeframe attached.
Share the approval when you ask for a final quote so the quoted work matches what has actually been authorised, and keep the paperwork with the property records.
Where to check, officially
- Blacktown City Council (opens in new tab) — current guidance for trees on private land and the application path
- The NSW Planning Portal Spatial Viewer (opens in new tab) — to check the planning layers shown for an address
- The NSW legislation website (opens in new tab) — for the current state planning instrument covering biodiversity and conservation
- NSW Rural Fire Service (opens in new tab) — to check whether the 10/50 vegetation clearing entitlement applies to the property
Last reviewed August 2026. We check these guides against the official sources whenever they change, and at least once every twelve months.
A practical order to work through
- Confirm Blacktown City Council covers the address.
- Work out whether the tree is tied to building work.
- Get a planning certificate or check the controls on the property.
- Read the council's current tree and vegetation guidance.
- Gather photos and write down exactly what you want done.
- Ask which application or exemption process applies.
- Arrange any independent report requested.
- Get the approval before the work is booked.
Common questions
The builder said they would handle the trees. Should I check?
Ask to see it in writing. Trees are often covered by a development consent, but "we'll sort it" is not a consent condition. Get the detail before anything comes down.
Can I remove a tree to make room for a granny flat?
That is normally assessed with the building work rather than separately. Lodge it the right way round and check what the consent says about the trees.
The tree is on the boundary. Whose is it?
Work out where the trunk sits and who owns that land before anything else. Boundary trees involve the neighbour as well as the council, and it is much easier sorted out early.
Does a quote from you count as approval?
No. A quote sets out the tree work and the price. Where approval is required, it is a separate step and it comes first.
How long will the council take?
That depends on the current process and the information needed. Check the council's published guidance rather than planning around a guess.
What to do next
Check the council requirements for the address, then send us photos of the tree, the way into the yard and anything close by — and tell us if there is building work involved. We will start the quote and let you know if we need to see it first.
