In most cases, yes. Under Newton’s Tree Preservation Ordinance, you need a permit, or an approved exemption form, before you remove a tree that is 6 inches or more in diameter, measured at about chest height. On an occupied single- or two-family home with no construction planned, most trees between 6 and 39 inches only need the free exemption form.
The rules were updated in 2024, and many homeowners don’t know about them until a neighbor or the city asks. Here is a plain-English guide to how they work. The city’s rules can change, so always check the current details with Newton’s Urban Forestry office before work starts.
Which trees are covered?
The ordinance covers trees with a trunk diameter of 6 inches or more. Arborists measure this as DBH, or “diameter at breast height,” which is 4.5 feet above the ground. To estimate it, measure around the trunk with a tape and divide by about 3.14.
Trees on the city strip between the sidewalk and the street are public shade trees. They belong to the city and are handled by Newton’s Tree Warden. Don’t remove or prune those yourself.
The three paths for homeowners
1. Exemption form (no fee)
If you live in a single- or two-family home, the tree is between 6 and 39 inches DBH, and no exterior construction is underway or planned on the lot for the next 24 months, you can file an exemption form with the city. There is no charge.
2. Permit for large trees or other lots
Trees 40 inches DBH or larger on a residential lot, and trees on non-residential lots, need a tree removal permit. There is a fee, and you may need to plant replacement trees or pay into the city’s tree fund.
3. Permit when there is construction
If there is exterior construction on the lot, like an addition, a new driveway or a new house, removing protected trees needs a construction permit. The permit can also require a protected “tree save area” around trees that are staying, so roots are not damaged during the work.
Dave’s tip
Planning an addition or a new patio in the next two years? Talk to us before you take any trees down. Removing a tree now can still fall under the construction rules later.
What the city will ask for
- A tree removal form that describes the trees and where they are.
- For some permits, a form filled out by a certified arborist.
- For trees removed because of risk, an arborist’s tree risk assessment.
- A plan for replacement trees, or payment in lieu of planting.
DJ Snyder is led by a consulting arborist, and we help homeowners with this paperwork all the time. We can measure the tree, describe its condition and tell you which path applies.
What about dead or dangerous trees?
If a tree is an immediate danger, for example it has split in a storm and is leaning on a house, call a tree company right away and contact the Urban Forestry office to ask what paperwork they need. For trees that are dying but not an emergency, plan on the normal process. An arborist’s risk assessment helps.
Who to contact
Newton’s Urban Forestry office, part of Parks, Recreation and Culture, runs the tree ordinance. You can find the current forms and fees on the City of Newton website, or email the office at urbanforestry@newtonma.gov.
Frequently Asked Questions
How do I measure the diameter of my tree?
Wrap a tape measure around the trunk 4.5 feet above the ground. Divide that number by 3.14. For example, a trunk that measures 31 inches around is about 10 inches in diameter.
Do I need a permit to prune a tree in Newton?
The ordinance is about removing trees, so normal pruning on your own property is usually not covered. Public shade trees on the city strip are different, and only the city can approve work on them. If you are not sure, ask the Urban Forestry office.
Does the tree company get the permit, or do I?
It depends on the job. The permit is tied to your property, so you are responsible for it, but a good tree company will help you fill out the forms and tell you what the city needs.
What happens if I remove a tree without a permit?
The city can step in and require replacement trees or payments into its tree fund. It is much easier to file the paperwork first.
