If the tree on your property poses an immediate risk to the property surrounding it or people nearby, you can apply for something called an exemption permit. Exemption permits for tree removal are usually granted for dead trees, trees that are imminently hazardous, or trees with advanced disease (where tree failure is inevitable). Exemption permits do not require Arborist Reports, like some other permit applications require.

To be safe and avoid fines, it is a good idea to have a certified arborist assess the situation and determine the safest and best way of proceeding.
