Independent tree-rule information · Not a government or arborist service
Private-tree planning tool

Measure the tree, then check the rule that actually applies.

Choose a city and enter the trunk diameter. A numeric comparison appears only where the linked municipal material contains a clear private-tree signal.

Choose a municipality and enter what you know.

Diameter is only one possible trigger

Species, heritage or replacement status, development activity, riparian/environmental areas, ownership and public-tree rules can matter independently. The checker therefore never turns “below the number” into a blanket permission to remove a tree.
