Tree Trimming Rules and Guidelines for Kansas City Homeowners

Short answer: In the Kansas City area you can trim the trees on your own lot without a permit. Keep branches clear over sidewalks (commonly about 8 feet) and higher over the street, ask your city before touching a tree in the right-of-way strip, leave work near power lines to the utility, and never remove more than about a quarter of a tree's live crown at once.

Tree trimming rules in the Kansas City area are not complicated, but most homeowners never hear them until a city notice or a neighbor complaint arrives. Here is the short version. Confirm with your city.

Clearance Over Sidewalks and Streets

Most metro cities expect branches to be kept clear over sidewalks and streets, commonly around 8 feet over a sidewalk and higher over the street, so pedestrians and trucks can pass. Cities can send notices when trees block signs, lights or sightlines at corners.

Right-of-Way Trees

Trees in the strip between the sidewalk and the street are often city trees. Ask your city before trimming or removing them.

Will the City Trim a Tree on My Property?

Generally not. A tree on your lot is yours to maintain. A city can send a notice when a private tree blocks a sidewalk, a street, a sign or a sightline at a corner, and expects the owner to fix it. Trees in the right-of-way are the city's to maintain; in Kansas City, Missouri, you can ask for work on one through 311.

Your Tree, Your Neighbor’s Tree

You can generally trim a neighbor’s branches that hang over your lot, up to the line, without killing the tree. See property line tree disputes.

HOA Rules

HOAs often set their own clearance and appearance rules, and some limit heavy pruning.

Utility Lines

The utility trims around its own lines. Never trim near a power line yourself; electricity can arc through branches and tools.

Good Pruning Practice

• Cut just outside the branch collar; no flush cuts, no stubs.
• Use the three-cut method on heavy limbs.
• Remove no more than a quarter of the live crown at once.
• Never top a tree.
• Prune oaks only in the dormant season.

See the common mistakes below and the best time for tree trimming.

How Much Can You Cut Off Without Killing the Tree?

About a quarter of the live crown in one season is the practical limit for a healthy, mature tree, and less for an old or stressed one. Taking more forces the tree to push out a mass of weak sprouts and can starve the roots. If a tree needs more than that, the work is spread over two or three years.

When Not to Trim

Avoid heavy pruning in spring while leaves are coming out, when the tree has just spent its stored energy. Oaks should not be cut from spring into summer because of oak wilt. In a drought, hold off on anything that is not dead or dangerous until the tree has had water.

When a Permit Is Needed

Normal trimming on your own lot does not need one. City trees and some development and historic situations do; see do you need a permit.

Common Violations

• Low limbs blocking a sidewalk
• Trimming or removing a city tree without asking
• Topping a tree in an HOA that prohibits it

Hiring a Trimming Crew

Ask for proof of insurance, a written estimate that names the work, and how they will protect the yard. An arborist can tell you what a tree actually needs; a hazardous tree evaluation covers trees that worry you. See our trimming and pruning service, and stump grinding if a tree is coming out. For why it is worth doing, see why trimming matters for property value.

Who Is Responsible for Which Tree?

• A tree on your lot: you, including keeping the sidewalk and street clear.
• A tree in the right-of-way: usually the city. Ask before you cut.
• Branches near power lines: the utility (Evergy in most of the metro) clears around its lines.
• A neighbor's branches over your yard: you may trim them back to the line at your own cost, without harming the tree.
• Common areas in a subdivision: usually the HOA.

Common Trimming Mistakes Homeowners Make

• Topping the tree. Cutting the top off to make a tree smaller sends up a mass of weak sprouts, and decay moves into the big cuts. A topped tree is more dangerous than before.
• Flush cuts and stubs. A flush cut removes the branch collar and the tree's defense; a long stub rots back into the trunk.
• Taking too much at once. More than about a quarter of the live crown stresses the tree and invites sprouts and sunscald.
• Skipping the three-cut method. On a heavy limb: an undercut a foot out, a top cut just beyond it to drop the limb, then the final cut at the collar. One cut tears the bark down the trunk.
• Pruning oaks in the growing season, which invites oak wilt.
• A ladder and a chainsaw. The most common way homeowners get badly hurt. A cut limb can kick the ladder out.
• Ignoring what is below: power lines, the service line to the house, roofs, fences, cars.

What You Can Safely Do Yourself

• Small branches you can reach from the ground with hand pruners or a pole saw
• Dead twigs and suckers
• Structural pruning on young trees

Anything above head height, anything near a line or the house, and any big tree is a job for a crew.

Frequently Asked Questions

Do I need a permit to trim trees in Kansas City?

Not for normal trimming of trees on your own lot. Trees in the public right-of-way need the city's permission.

How much of a tree can I cut off without killing it?

About a quarter of the live crown in one season for a healthy tree, less for an old or stressed one.

Who pays to trim a neighbor's overhanging branches?

Usually you, if you want them trimmed and they are healthy. If they are dead or dangerous, let your neighbor know in writing.

When should trees not be trimmed?

Skip heavy pruning while leaves are coming out in spring and during droughts, and leave oaks alone from spring into summer because of oak wilt.
