Responsibility for trimming trees near power lines splits three ways. The utility company handles vegetation around its transmission towers and the distribution lines running pole to pole through your neighborhood. You are responsible for trees near the service drop, the smaller line that connects the utility’s pole to your house. Local government manages trees in public rights-of-way, parks, and other city land. Which rule applies in any given situation comes down to which line the tree threatens.
Identify the Line Before You Do Anything
Three types of power lines serve a typical home, and the responsibility rules track them exactly.
- Transmission lines are the high-voltage lines (often 200,000 volts or more) carried on large metal towers across long distances. Transmission owners have sole responsibility for vegetation around them under a federal reliability standard, NERC FAC-003-4.1Federal Energy Regulatory Commission. Transmission Line Vegetation Management
- Distribution lines carry lower-voltage electricity (typically 4,000 to 36,000 volts) along wooden poles through neighborhoods. The utility is responsible for trimming trees that threaten these pole-to-pole lines, under rules set by each state’s public utility commission.2Federal Energy Regulatory Commission. Tree Trimming and Vegetation Management Landowners FAQ
- Service drops are the smaller lines connecting the distribution pole to your home’s meter. Though the utility owns the line, the property owner is generally responsible for keeping trees trimmed around it.
The transmission–distribution split matters because federal authority only reaches transmission-level vegetation management. Everything at the distribution level and below is governed by state regulators, so trimming schedules, notification rules, and cleanup practices vary by utility.2Federal Energy Regulatory Commission.

What the Utility Handles
For transmission lines, the federal standard requires transmission owners to manage vegetation so trees never encroach within a minimum clearance distance of energized conductors, accounting for how conductors move under load and how fast vegetation grows between inspections.3Federal Energy Regulatory Commission. FAC-003-4 Transmission Vegetation Management
For distribution lines, state public utility commissions set the rules. Most require utilities to file long-range trimming plans and work through regular cycles. Utilities do this work proactively rather than waiting for a branch to touch a wire. The crews that perform it are specialists: OSHA defines “line-clearance tree trimming” as any pruning, trimming, removing, or clearing of trees within 10 feet of energized power lines, and the workers must carry specialized training, use insulated tools, and determine the voltage of nearby lines before starting.4Occupational Safety and Health Administration. Line-Clearance Tree Trimming Operations
Cleanup after a scheduled utility trim depends on the company. Many will chip the small material and leave larger pieces cut to manageable lengths near the tree. Storm restoration is different: crews focus on clearing debris off the lines to restore power, and the resulting wood on your property is generally left for you. Ask your utility about its cleanup policy before work begins.
What Falls to You
Your responsibility centers on the service drop. Most utilities explicitly exclude that line from their trimming programs, so if a branch is growing into the wire running to your house, arranging the trim is on you.
Do not try to cut it yourself. Even the service drop carries enough voltage to be lethal, and OSHA requires unqualified people to stay at least 10 feet from any energized line, with greater distances at higher voltages.4Occupational Safety and Health Administration. Line-Clearance Tree Trimming Operations Instead, call your utility and request a temporary disconnect, or ask them to place protective rubber sleeves over the service wires so a qualified tree contractor can work safely. Many utilities want at least five business days of notice to coordinate.
You also carry long-term responsibility for trees entirely on your land that aren’t a problem yet but will become one. A species planted under a distribution line will keep forcing the utility back to prune it, often into an unnatural shape, for as long as the tree lives.
Who Pays
Utility-initiated trimming around transmission and distribution lines almost never produces a direct bill to the property owner. Those costs are built into electric rates. If the utility’s vegetation crew comes out to trim a tree on your land that threatens their lines, no invoice follows.
Costs you can face are tied to the service drop. Hiring a private arborist to trim near your service line is your expense. The temporary disconnect or sleeving service is free from some utilities and carries a fee from others, so call ahead to confirm.
If a tree falls on utility lines during a storm, the utility will clear the tree off its equipment and repair the lines at its own cost, but the remaining debris on your property is yours. Homeowner’s insurance may cover part of the cleanup, so a claim is worth considering when the damage is significant.
Easements and What They Allow
Most of the utility’s authority to come onto your property and trim comes from an easement, a legal right to access and maintain a strip of land around the power lines. This right-of-way typically runs with the deed, meaning it transferred to you when you bought the house whether or not anyone mentioned it at closing.2Federal Energy Regulatory Commission. Tree Trimming and Vegetation Management Landowners FAQ
Inside the easement, the utility generally has the right to trim or remove any vegetation that threatens its lines. The federal vegetation management requirement reaches only property the utility controls through a fee or easement, so a crew that trims trees outside the established right-of-way has exceeded its authority.1Federal Energy Regulatory Commission. Transmission Line Vegetation Management
If you want to challenge a utility’s trimming, your arguments are generally limited to two: the utility exceeded the rights the easement granted, or the easement itself is invalid. Reviewing your deed and the easement language with an attorney is the practical first step. Simply refusing access when the utility holds a valid easement rarely works and can lead to legal action.
Trees on City Land
Municipal governments manage trees in public rights-of-way, parks, and other city-owned land, including street trees near power lines. Public works or urban forestry divisions handle the trimming, often coordinating directly with the utility.
If a tree in a public right-of-way near your home is growing into the lines, call the utility first because the tree threatens their infrastructure. If the same tree is a hazard for other reasons, like blocking sightlines or dropping limbs on a sidewalk, your city’s 311 service or public works department is the right contact.
Hiring a Contractor for Work Near Lines
If you are hiring private tree work near any power line, the contractor’s qualifications matter. OSHA recognizes three tiers of workers around energized lines: unqualified employees who must stay at least 10 feet away, qualified employees under the general electrical safety standard, and line-clearance tree trimmers trained to work within 10 feet of energized conductors.4Occupational Safety and Health Administration. Line-Clearance Tree Trimming Operations
Only line-clearance tree trimmers should work near energized lines. They determine the voltage of all nearby lines before starting, use insulated tools inside the minimum approach distance, and stop work in high winds or lightning.4Occupational Safety and Health Administration. Line-Clearance Tree Trimming Operations A regular tree service with a chainsaw and a bucket truck is not the same thing. Ask directly whether the company employs line-clearance certified trimmers before you hire.
For work near your service drop, calling the utility first for a temporary disconnect is often the cheaper path, because once the line is dead, any competent arborist can do the job.
Reporting a Hazard
If you see a tree or branch threatening a power line, report it to the utility. Most offer an emergency hotline for immediate dangers like branches on wires or downed lines, and a non-emergency number or online form for slower problems like a tree gradually leaning toward a line. Give the street address and describe what you see, including whether contact has already happened and whether anything is sparking or smoking.
Downed lines deserve extra caution. Assume a fallen line is energized even if it looks dead. Stay at least 10 feet from the line and anything it might be touching, including fences, trees, and puddles.5Electrical Safety Foundation International. Power Lines Safety Tips Call 911 first, then the utility’s emergency line. Do not try to move the line or anything in contact with it. The ground near a downed line can carry voltage outward, and distance is your only real protection.
