No permit is needed for planting or pruning, as long as the pruning does not irreparably damage the tree. A permit is needed to remove any tree with a diameter at breast height (DBH) of eight inches or greater or an ornamental or evergreen tree with a height of 10 feet or more. Residents should consult the Tree Removal Instructions where they will find a link to the Application for a Tree Removal Permit. An Enforcement Officer will respond within 20 days to grant or deny the application.
For penalties, please consult Section 22-16 of the Princeton Trees and Shrubs Ordinance adopted by the Princeton Council in 2016 and amended in 2020. Each regulated tree removed without a permit is considered a separate violation.
Exceptions to the permit process include, among other conditions, dead trees that are standing and Ash trees, due to the infestation of the Emerald Ash Borer (EAB). However, even in these cases, applicants should file permit applications before written permission is granted by the Enforcement Officer.
