Whether you need a permit to cut down a tree on your property depends almost entirely on local law. Hundreds of cities and counties regulate tree removal on private land, and their rules vary based on the tree’s trunk size, species, location on your lot, and your reason for cutting it. Some municipalities require a permit for any tree above a set diameter; others regulate only protected species or trees in sensitive areas; a few barely regulate private removal at all. Before you pick up a chainsaw, check your local ordinance.
How to Check the Rules Where You Live
Start with your city or county planning department, building department, or urban forestry division. Most local governments post their tree ordinances online, and a phone call to the right office will usually get you a clear answer within minutes. Search your municipality’s name along with “tree removal permit” or “tree preservation ordinance.” If you live in an unincorporated area, your county handles this instead of a city.
Which department owns the issue varies. Some cities route everything through planning and zoning; others have a dedicated urban forestry office or parks department. Two other authorities may apply on top of the local ordinance: if your property is in a homeowner association, the HOA has its own tree rules, and if the tree is near a power line, the utility company has independent authority.
What Usually Triggers a Permit Requirement
Most tree ordinances key off one or more of these factors: trunk diameter, species, location on your property, or whether the removal is tied to a construction project.
Trunk Size
The most common trigger is trunk diameter at breast height (DBH), measured about 4.5 feet above the ground. Many jurisdictions set the threshold somewhere between 6 and 10 inches, though the exact number varies widely. Some cities go as low as 2.5 inches for street trees. If your tree meets or exceeds the local threshold, you need a permit.
Protected and Heritage Trees
Many municipalities designate certain species as protected, typically natives or varieties with ecological significance. Heritage, specimen, or landmark trees get stronger protection, often defined as those exceeding a larger diameter (commonly 24 inches or more). Removing a protected tree usually requires a specific justification, such as the tree being dead, diseased, or hazardous, and some cities require a certified arborist to confirm the hazard before approving removal.
Where the Tree Sits
Trees in certain zones almost always require permits regardless of size or species. These include public rights-of-way, conservation easements, riparian buffers near waterways, and wetland areas. Even on your own lot, a tree inside a setback, near a property line, or within an environmental overlay may be regulated differently than one in the middle of your backyard.
Removal Tied to Construction
If you’re clearing trees as part of a building project, the permit question typically folds into your development review. Planning boards and site plan approvals often include an urban forestry component that evaluates affected trees and sets mitigation. Some jurisdictions impose canopy coverage minimums by zoning classification, and dropping below that threshold triggers replacement requirements even for trees that would otherwise be exempt.
When You Usually Don’t Need a Permit
Several exceptions appear across most ordinances. Verify your local rules before relying on any of them.
- Emergency hazards. A tree posing an immediate threat to life or property, such as one about to fall on your house after a storm, can usually be removed without waiting for a permit. Document the hazard with photos and, if possible, a written arborist assessment. Many jurisdictions still require you to notify the city within a set number of days afterward.
- Small trees. Trees below the local diameter threshold are generally exempt. If the ordinance kicks in at 8 inches, a 6-inch tree is yours to cut.
- Invasive species. Non-native or invasive species are often exempt, and some municipalities actively encourage their removal.
- Dead trees. Obviously dead trees are frequently exempt, though some ordinances still require a city arborist to confirm the condition first.
- Fruit trees. Residential fruit trees are commonly exempt from tree preservation ordinances.
How to Measure Your Tree’s Diameter
Because trunk size is usually the deciding factor, measuring correctly matters. DBH is the trunk diameter at 4.5 feet above the ground. Wrap a flexible tape measure or string around the trunk at that height, then divide the circumference by 3.14 to get the diameter.
If the tree sits on a slope, measure 4.5 feet along the center of the trunk so the height averages the uphill and downhill sides. If the trunk splits below 4.5 feet, measure the smallest circumference below the lowest split point. For multi-stemmed trees, measure each stem separately.
What the Permit Process Looks Like
If a permit is needed, the application is generally straightforward. Expect to provide your contact information, the property address, the tree’s location on the lot, its species if you know it, and its trunk diameter. You’ll also need to explain why you want it removed. Some applications ask for a site plan showing the tree’s position relative to structures and property lines, photos of its condition, and an arborist report if the tree appears healthy.
Application fees typically run from $25 to $200. If an arborist report is required and you don’t already have one, expect $150 to $450 for a certified arborist’s assessment. Submit through your local planning or forestry department’s website, by mail, or in person.
A city arborist or planner then reviews the application and may visit to inspect the tree. The timeline ranges from a few days to several weeks. If approved, your permit may come with conditions: a deadline for completing the work, requirements for how the stump is handled, and whether you must plant replacement trees.
Federal Wildlife Laws Apply Even Without a Local Permit
Even if your city has no permit requirement, federal law may still restrict when and how you remove a tree. This catches many homeowners off guard.
The Migratory Bird Treaty Act
The Migratory Bird Treaty Act makes it illegal to destroy the nest or eggs of any protected migratory bird, which covers nearly all native songbirds, raptors, and waterfowl. If a protected bird has an active nest in your tree, cutting the tree down violates federal law regardless of what your local permit says. A misdemeanor conviction carries fines up to $15,000 and up to six months in jail per violation.1Office of the Law Revision Counsel. 16 USC 707 – Violations and Penalties
If you’re removing a tree during nesting season (roughly March through August in most of the country), inspect it carefully for active nests first. Waiting until late fall or winter largely eliminates the risk, since the law protects active nests, not empty ones from previous seasons.2Office of the Law Revision Counsel. 16 USC 703 – Taking, Killing, or Possessing Migratory Birds Unlawful
The Endangered Species Act
If your tree provides habitat for a species listed as threatened or endangered, removing it could constitute an illegal “taking” under the Endangered Species Act. This is less common than the nesting-bird issue, but it applies on private property and carries serious penalties. The law prohibits any action that harms or harasses a listed species, and destroying habitat a listed species depends on can qualify.3U.S. Environmental Protection Agency. Summary of the Endangered Species Act
Power Lines, HOAs, and Boundary Trees
Three other authorities can override or add to your local tree rules.
Utility easements. Utility companies hold easements on many residential properties, giving them the legal right to trim or remove trees that threaten power lines. Those rights are typically spelled out in a right-of-way agreement attached to your deed. Vegetation management decisions are primarily the utility’s, subject to state and local requirements and the easement terms. For large interstate transmission lines (200 kV and above), the Federal Energy Regulatory Commission sets mandatory clearance standards; for distribution lines serving neighborhoods, state utility commissions set the rules.4Federal Energy Regulatory Commission. Tree Trimming and Vegetation Management Landowners FAQ Don’t attempt to remove or trim a tree touching or within 10 feet of a high-voltage line. Call the utility; many will handle the removal at no cost because they have a legal obligation to maintain clearance.
HOA rules. If your property falls within a homeowner association, the CC&Rs may impose tree removal rules on top of what your city requires. Many HOAs require written approval before removing any tree, including species that are unregulated under local ordinance. Review your CC&Rs for the specific provisions, and expect a formal request process that takes several weeks. For genuinely hazardous trees, HOAs generally cannot block removal needed to protect life and property, but written documentation from a certified arborist strengthens your position.
Boundary trees. A tree growing on the property line between your yard and your neighbor’s is a “boundary tree,” and the common-law rule is that both owners share ownership. Removing it without your neighbor’s consent is unlawful in most jurisdictions. Overhanging branches are different: you generally have the right to trim branches that cross onto your side, but only up to the property line, and only to the extent that the trimming doesn’t destroy the tree’s structural integrity or kill it. Improper trimming can expose you to liability of up to three times the tree’s value in some jurisdictions.
Penalties for Cutting Without a Permit
The consequences for unauthorized removal range from annoying to financially severe.
- Fines. Monetary penalties are the most common consequence and run from a few hundred to several thousand dollars per tree. Some municipalities impose fines exceeding $10,000, particularly for heritage or protected trees. In jurisdictions that allow treble damages, you could owe up to three times the appraised value of the tree.
- Mandatory replacement planting. Many ordinances require replacement trees, often at a ratio greater than one-to-one. Larger or more valuable trees typically trigger higher ratios, and you pay for the trees and the planting.
- Liens on property. Unpaid fines and the cost of required replacements can result in a lien against your property, which clouds the title and can block a sale.
- Stop-work orders. If the removal was part of a construction project, the municipality can halt all work on site until the violation is resolved. The delay typically costs far more than the permit would have.
Penalties tend to escalate when the removal was clearly intentional rather than the product of honest confusion. Documenting your good-faith effort to check the rules before cutting, even if you ultimately got it wrong, puts you in a far better position than someone who never asked.
