Who decides about a common-property tree?
The owners corporation (the body corporate, in some states), usually through its committee or a general meeting. For council purposes, one owner or a tenant generally can't sign off: Hornsby says tenants can't give permission, and strata or common property needs an authorised officer or the body corporate.
The law points the same way. Queensland's neighbour tree law treats the body corporate as the tree-keeper for a tree on common property, and in the ACT an application about a protected tree on units plan (strata) common property needs the owners corporation's written agreement. How your scheme votes is set by your state's strata law and by-laws, so ask the strata manager.
What councils ask strata schemes to provide
- Minutes of a body corporate or executive committee meeting agreeing on the tree work (Randwick).
- A managing agent's letter, or minutes showing majority support (Mosman).
- The owners corporation's seal, plus a site plan with the trees numbered (Cumberland).
- A manager's letter and the owners corporation number (Stonnington).
- The body corporate's seal if the applicant isn't the owner, plus photos and a location map (Brisbane).
- An arborist report, where the council asks for one. See arborist reports.
Do council shortcuts work for strata?
Not always. City of Ryde's urgent tree assessment is only for non-strata homes, and City of Gold Coast says its accepted development guidelines don't apply to trees on land managed by a body corporate. Plan for the normal application, and allow time for a meeting before it. Our permit pages cover the rules council by council.
What's different on a commercial site?
Mostly the people around the work. Safe Work Australia says the people doing tree work, or working near it, are the most at risk, and that an exclusion zone should be set up below and around the tree. On a busy site that can mean closing car park bays, paths or an entrance for the day, so plan it with the site manager.
In NSW, SafeWork NSW's Tree works code of practice, in force from 27 March 2026, covers everyone who works with trees, builders and developers included. If there's construction, the trees come under AS 4970:2025 and protection zones, which our tree protection zones guide explains.
How long should we allow?
Longer than for a house. The ACT has to decide a tree activity application within 35 working days, and Brisbane says it will contact you about a protected vegetation permit within 20 business days. Add the wait for the next meeting, then book the work for when the site is quietest. For routine pruning, a yearly arborist inspection beats reacting to each fallen branch.
Strata and commercial tree work: what you can do yourself
You can
- Photograph the tree and the problem, with dates.
- Put the tree on the next meeting agenda with a clear motion.
- Ask the council what it needs from a strata or commercial applicant.
- Ask each arborist for proof of public liability and workers compensation insurance.
Leave to an arborist
- The assessment and any report.
- Pruning and removal, with an exclusion zone in place.
- Stump grinding and the clean-up.
Hiring an arborist for strata and commercial work
We'd get the arborist's report first, table it with a clear motion at the next meeting, and lodge the council application with the minutes attached. That's the order most councils want anyway, and it stops one tree dragging across three meetings.
