Tree Laws in Maryland (2026): Rules Every Property Owner Must Know
Most people assume they can do whatever they want with trees on their property. Cut them down, trim them, remove them. No big deal, right?
Wrong. Maryland has some of the strictest tree laws in the country. And breaking them can cost you thousands of dollars. Let’s break down exactly what you need to know.
What Are Maryland Tree Laws?
Maryland tree laws are a set of rules that control how you can plant, trim, and remove trees. They protect public trees, forest land, and even trees on private property in some cases.
These laws exist for good reasons. Trees clean the air and water. They prevent flooding. They cool neighborhoods. Maryland wants to keep them around. Personally, I think that makes a lot of sense.
There are several different laws at play here. Each one covers a different situation. Understanding which one applies to you is the first step.
The Maryland Roadside Tree Law
What It Covers
Okay, this one is important. The Maryland Roadside Tree Law has been around since 1914. That is over 100 years of tree protection. It covers any tree that grows within a public road right-of-way.
A right-of-way is basically the strip of land along a road. It might look like your yard. But legally, it often belongs to the public. Trees growing in that area are protected.
What You Need a Permit For
Want to trim a street tree? You need a permit. Want to remove one? You need a permit. Want to plant a new tree along a road? Still need a permit.
You have to get that permit from the Maryland Department of Natural Resources (DNR) Forest Service before doing any work. Not after. Before.
Wondering if this applies to the tree near your mailbox? If that tree sits near a public road, there is a good chance it does.
Who Can Do the Work?
Here is the part most people miss. You cannot just hire any tree service in Maryland.
Anyone being paid to work on, evaluate, or give advice about trees must be a Licensed Tree Expert (LTE). That is required by state law. The license is issued through the Maryland DNR Forest Service.
Before you hire someone, check their license. You can verify it by visiting the Maryland Forest Service website or calling 410-260-8521.
Penalties for Breaking the Roadside Tree Law
Now, here is where things get serious. The fines are not small.
If you trim, cut, remove, or injure a roadside tree without the right permits, you are looking at real money. A first offense can cost you up to $2,000. A second or later offense can run up to $5,000.
Think of it like a traffic ticket, but way more expensive. And unlike a parking ticket, these violations can follow you.
Also, permits are only valid for one year. If you do not finish the tree work in time, you need a new permit. And a new inspection too.
The Maryland Forest Conservation Act
What It Is
The Maryland Forest Conservation Act (FCA) was passed in 1991. It was designed to protect forests during land development. It is still one of Maryland’s most important environmental laws.
The basic idea is simple. If you are building something and trees are in the way, you cannot just clear them out. You have to plan around them. Or replace them.
Who It Applies To
This law mainly affects developers and larger property owners. But it can affect homeowners too. Especially if you are building something new or getting a grading permit.
If you are clearing more than 5,000 square feet of trees, pay attention. You likely need a grading permit. And that permit comes with forest conservation rules attached.
Most regular homeowners removing a single tree do not trigger this law. But it depends on your county. Always check with your local planning department first.
Forest Conservation Plans
Here is where it gets a little more complex. For projects that do apply, you need to submit a Forest Stand Delineation (FSD) and a Forest Conservation Plan (FCP).
These documents map out where the forest is. They show what will be removed. And they explain how the impact will be offset.
These plans must be prepared by a licensed forester or licensed landscape architect. You cannot just draw one up yourself.
Neighbor Tree Disputes in Maryland
The Self-Help Rule
A friend asked me about this one last week. Her neighbor’s tree was hanging over her fence. She wanted to know what she could do about it. Turns out, most people get this wrong.
Maryland follows what is called the “Massachusetts Self-Help Rule.” It sounds fancy. But it basically means this: you can trim branches that hang over your property. However, you must stop at the property line. You cannot go onto your neighbor’s land to do it.
And here is the big one. You cannot destroy the tree in the process. You can trim. You cannot kill.
Getting Permission First
If you want to do anything beyond simple trimming at the property line, get your neighbor’s written permission first. Not a verbal agreement. Written. It protects both of you.
You also cannot trespass onto a neighbor’s property to cut their tree. Not without permission. Even if the tree is driving you crazy.
When Trees Fall
So what happens when a tree falls onto your property? Maryland treats fallen trees as an “Act of God.” That means the cleanup is your responsibility if the tree falls onto your land.
There is one exception. If the neighbor knew the tree was dead or dangerous and did nothing, they may be liable. But that is a legal gray area. Honestly, this is the part most people end up fighting about.
Trespassing and Unauthorized Tree Removal
Hold on, this part is important. If someone cuts down or removes trees from your property without permission, that is a serious legal matter.
Under Maryland law, a person who trespasses and removes trees without the owner’s permission can be held responsible for up to triple the value of the trees removed. Plus court costs. Plus any surveys or appraisals needed.
Triple the value. That is not a typo. Maryland takes unauthorized tree removal very seriously.
County-Level Tree Laws
Maryland lets counties create their own tree rules. And many counties go above and beyond state law. This is where it gets really local.
Montgomery County
Montgomery County has its own Roadside Tree Law on top of the state one. If you live there and want to work on a street tree, you actually need two permits. One from the state. One from the county.
Montgomery County also has a Forest Conservation Law updated as recently as December 2025. It aims for no net loss of forest in the county. It applies to properties over 40,000 square feet that are doing development work.
There is also a Tree Canopy Law. If development removes trees, fees are charged to pay for new plantings. As of April 2024, that fee is $470 per tree.
Prince George’s County
In Prince George’s County, you generally do not need a permit to remove a single tree on your own property. But if that tree is near a public road, the state Roadside Tree Law still applies.
And if you are clearing more than 5,000 square feet, you need a grading permit. That brings the FCA into play.
Other Counties
Every county in Maryland may have its own rules. Some are stricter. Some match state law exactly. Always check with your local planning or permitting office before removing trees.
How to Stay on the Right Side of the Law
You are not alone if this feels like a lot to navigate. Most people do not realize how layered these rules are. But staying legal is not that hard once you know the steps.
First, figure out where the tree is. Is it on your private property, near a road, or in a forested area? That determines which laws apply.
Second, contact your local county planning or permitting office. They can tell you what permits you need. This call is free. The fine is not.
Third, hire a Licensed Tree Expert. Do not skip this step. Verify their license through the Maryland DNR Forest Service. Ask for proof of insurance too.
Fourth, get your permits before starting any work. Do not start work and apply for a permit later. That is not how it works.
Stay with me here, because this last step matters a lot. If you are near a public road, check whether state and county permits are both required. In some places like Montgomery County, you need both.
Frequently Asked Questions
Do I need a permit to cut down a tree in my own backyard in Maryland? For a single tree not near a public road, you often do not need a permit. But this depends on your county, so always check locally before cutting.
What is a Licensed Tree Expert in Maryland? A Licensed Tree Expert (LTE) is someone certified by the Maryland DNR to work on trees for pay. Hiring an unlicensed person for tree work is against state law.
Can I trim branches from my neighbor’s tree that hang over my yard? Yes, but only back to the property line. You cannot cross onto their property or damage the tree in the process.
What happens if I remove a roadside tree without a permit? You could face fines up to $2,000 for a first offense and up to $5,000 for later violations.
Does the Forest Conservation Act apply to my home? It usually applies during development projects or large-scale clearing. A single tree removal typically is not covered, but check with your county to be sure.
Final Thoughts
Maryland tree laws can feel confusing at first. There are state laws, county laws, and special rules for roads and forests. That is a lot.
But here is the simple version. If you are near a road, get a permit. If you are clearing a large area, check the FCA. And always hire a licensed professional. Do those three things and you will be fine.
Now you know the basics. When in doubt, call your county planning office or the Maryland DNR Forest Service. It is free to ask. The fines are not.
