Understanding Hills Shire Council Tree Rules and Approval Requirements
We make Hills Shire Council tree rules and removal guidelines easy to understand for property owners, builders and developers across the Hills Shire Council area, including Castle Hill, Kellyville, Baulkham Hills, Bella Vista and Norwest.
Our local Level 5 Arborists explain when Council approval is required, which trees may be exempt, and how pruning and removals must be managed under Council controls. With over 32 years of experience, we help clients stay compliant while protecting property, safety and trees.
When You Need Council Approval
- A tree exceeds Council size thresholds, including height, trunk diameter or canopy spread
- The tree is not listed as an exempt species
- Works involve significant pruning, canopy reduction or removal
- The property is within a heritage, conservation or environmentally sensitive area
- Trees are affected by development, construction or driveway works
A Level 5 Arborist assessment confirms approval pathways and prepares the documentation Council requires.
When You Don’t Need Council Approval
- The tree is listed on Hills Shire Council’s Exempt Tree Species List
- The tree is below Council size thresholds
- Minor pruning complies with AS 4373 Pruning of Amenity Trees
- Deadwood removal or routine maintenance pruning does not alter tree structure
If you’re unsure, our arborists can inspect, measure and confirm exemption status in writing.
