What is a Pre-Purchase Tree Inspection?
A pre-purchase tree inspection does for the trees what building and pest does for the house. Every significant tree on the property is assessed for three things: what it will cost you to look after, what condition it is in and how long it has, and whether you are legally allowed to remove it. It is for buyers who want to know what they are taking on, and what they will be able to change, before they sign.
Do I need a pre-purchase tree inspection?
If the property has established trees on it, almost certainly yes — because nothing else in your due diligence looks at them. Building and pest covers the house. Nobody is checking whether the fig near the boundary is protected, what the gum over the driveway will cost you in five years, or whether the tree in the back corner sits exactly where you were planning to put the pool. It matters most when:
-
You’re under contract
Your due diligence or building and pest window is the time to find out what the trees will cost you.
-
The block has established trees
Large established trees, acreage or a heavily treed site.
-
You plan to build after settlement
An extension, pool or new build near established trees can depend on what they are and whether they’re protected.
What building and pest inspections don’t cover
Building and pest inspectors assess structures and timber pests. They are not arborists, it is not in their scope, and no reasonable inspector would pretend otherwise.
What that leaves unchecked is the whole of the tree question: whether any tree on the block is protected under the local law, what condition the trees are actually in, what they will cost to maintain, and whether any of them would constrain what you intend to build. A building and pest report coming back clear tells you nothing at all about the trees.
What a pre-purchase tree inspection covers
Every significant tree on the property is assessed and written up individually, and the report answers three questions about each one: what it will cost you, what condition it is in and how long it has, and whether you are legally allowed to remove it. Those three between them cover almost everything a buyer actually needs to decide with — and the third is the one that most often changes somebody’s plans, because a protected tree is not a problem you can solve later with money.

How to get a Pre-Purchase Tree Inspection
To get a pre-purchase tree inspection you should engage an AQF Level 5 consulting arborist as soon as you go under contract, so the report lands inside your due diligence or building and pest window. Tell the arborist the property address, your due diligence expiry date and the agent’s details for access.

What it costs you if you skip it
Every one of these is discovered eventually. The only question is whether you find out before you sign or after you own it, and the difference between those two is the entire value of the inspection.
Protected trees you cannot remove
This is the expensive one. A tree protected under the local law is not coming out because you would prefer it did — not for shade, not for a view, not to make room. Councils refuse removal of healthy protected trees as a matter of course, and buying a property on the assumption that a tree can go later is buying a constraint you cannot undo. In Brisbane, ten named species become protected purely on size, with nothing on the title to warn you.
Trees that block a future build or pool
A protected tree does not just occupy its own footprint. Its root zone — typically twelve times the trunk diameter — is the area a build has to work around, and encroaching on it triggers an impact assessment and possibly a redesign. Plenty of pools and extensions that looked obvious on the contour plan are not achievable once the root zones are drawn on it.
Removal and maintenance costs you inherit
Large trees carry ongoing cost, and it transfers with the title. A mature gum over a roofline needing periodic deadwooding, a row of declining trees on a boundary, a stand that should have been thinned a decade ago — that is a recurring bill nobody mentioned at the open home. Knowing the number before you negotiate is worth considerably more than knowing it after.
Trees likely to fail after you own them
A tree with a structural defect over a house is a liability the moment the title changes hands, and once you own it you are the one who knew or ought to have known. Defects that a risk assessment would flag — included bark, decay at the base, a lifting root plate — are not visible to somebody walking the yard on inspection day.
Working inside your due diligence window
Standard turnaround is 2-3 business days from the site visit, and contract deadlines get priority over everything else in the queue. Most due diligence windows are workable if you ring on the day you go under contract rather than the day before the window closes.
What is needed to book: the property address, your due diligence or building and pest expiry date, and access arrangements — usually the agent’s details. That is enough to confirm the date before you commit to anything.
The inspection itself does not need you present and does not need the vendor to do anything beyond allowing access, which is the same access the building and pest inspector already has. Booking both for the same window is the efficient way to run it.
If the window is genuinely tight, say so when you enquire and you will get a straight answer on whether it is achievable rather than an optimistic one.
For buyers’ agents and conveyancers
If you advise buyers, tree risk is the due diligence gap you are currently carrying without a supplier. Building and pest does not cover it, and the first time it surfaces is usually after settlement when a client discovers the tree they planned to remove is protected.
What is offered: 2-3 business day turnaround with contract deadlines prioritised, a fixed fee quoted before the work, and a report written in plain English that a client can act on without needing it interpreted. Reports are authored at AQF Level 5 and name the assessor.
To refer a client, send the address and the due diligence expiry and it will be confirmed the same business day. For repeat referral work it is worth a conversation first — get in touch directly and we will set up something that fits how you work.
Methodology and standards applied
Reports are prepared against the standards and instruments assessors expect to see referenced.
- Visual Tree Assessment (VTA) methodology
- Useful Life Expectancy (ULE) assessment
- Council vegetation protection instruments for the relevant local government area
- AS 4970:2025 root zones, where the buyer intends to build
Pre-purchase tree inspection cost
A pre-purchase tree inspection is $475 including GST for a standard residential block, delivered in 2-3 business days. Acreage and heavily treed sites are quoted separately, because the work scales with the number of trees rather than with the price of the house.
It is a fixed fee agreed before the inspection, and it does not move afterwards. Put the property through the cost calculator, or see the full price list.
Pre-Purchase Tree Inspection questions
How do I know if a tree on the property is protected?
You generally cannot tell by looking, which is the whole problem. Protection comes from the local law and from council mapping, not from anything visible on the tree or recorded on the title. In Brisbane, ten named species become protected the moment the trunk passes a set size, with no register to search and no notification to anyone. Elsewhere it turns on overlays and vegetation protection orders. Checking the address against the instrument that applies is part of this report, and it is the single most valuable line in it.
What if the contract is already unconditional?
It is still worth doing, just for different reasons. You lose the ability to renegotiate or walk away, but you gain a costed picture of what you have taken on — what has to be done, in what order, and what it will cost — before you start making plans that a protected tree will not permit. Buyers who intend to build or landscape after settlement are better off knowing at that point than after the drawings are paid for.
Do you inspect acreage or rural properties?
Yes, quoted separately because the work scales with the number of trees rather than the size of the house. Acreage also brings in a layer suburban blocks rarely have: larger lots can carry mapped native vegetation regulated by the State under the Vegetation Management Act 1999, entirely separately from the council rules. On a rural-edge block that is worth establishing before you buy, not after.
Can the report be used to renegotiate the price?
Buyers do use it that way, and a costed, independent assessment of work the property needs is a considerably stronger position than an opinion. What it cannot do is manufacture a problem that is not there — the report says what it finds. Where it finds a significant protected tree blocking an intended build, or several thousand dollars of overdue work, that is a real and documented fact about the property and it is reasonable to take it into the conversation.
Why not just rely on the building and pest inspection?
Building and pest inspectors assess structures, not trees. They will not tell you that the fig near the boundary is protected under local law, that removing it later needs a permit you may not be granted, or that it has a decay pocket that will cost five figures to manage.
Can you turn this around inside my due diligence period?
Usually. Pre-purchase inspections run 2-3 business days as standard and contract deadlines get priority. Tell us your date when you enquire and we will confirm before you commit.
What if I plan to build or put in a pool?
Say so upfront and the report will assess whether protected trees sit where you want to build. That is the single most expensive thing to discover after settlement — and the cheapest to check before it.
Pre-purchase tree inspections across South East Queensland
Inspections are carried out across Brisbane, Moreton Bay, the Sunshine Coast, the Gold Coast, Redland, Logan and Ipswich. That matters more than it sounds on this particular report, because vegetation protection is set by the local law and the rules differ sharply between those seven — a tree that is unprotected on one side of a boundary can be protected on the other.
The report identifies the trees against the instrument that actually applies to that address rather than a general statement about Queensland. The rules for each council are set out separately.
