When trees start growing too close to power lines, you might start wondering if you’re responsible for trimming and what it is going to cost. But before you trim anything or hire someone to do it for you, it’s important to understand exactly who is responsible for trimming trees near power lines.
In this blog, you’ll find out when the utility company should step in, what you’re liable for, and when to call Frank’s Arborcare LLC for expert tree services in Trumbull, CT.

Utility Company Responsibility
The highest voltage lines at the top of the pole fall under utility company responsibility. Crews trim these lines on a set schedule using licensed professionals. You’ll usually get advance notice before work begins near your property. If you’re unsure who is responsible for trimming trees near power lines, contact your power provider to find out what they cover.
Property Owner Liability
Lines that drop from the pole to your home, like service or cable wires, fall under property owner liability. You’re responsible for keeping trees clear of these lower lines. If branches touch them, they can cause outages or even spark fires near your home. Never trim around live wires yourself. Call a licensed professional if limbs are close to avoid serious damage or injury.
Tree Trimming Laws and Clearance Standards
Tree trimming regulations define the minimum distance branches must be from energized wires. Utility crews cut beyond those limits to prevent regrowth from reaching back into the hazard zone. If you ignore these rules, you could face code violations, forced removal, or legal action.
Cutting too close may also leave you liable if your tree causes damage. Power line clearance standards are in place to protect utility workers, your property, and your neighbors. Once the legal limits are clear, address the physical risks.
How Tree Hazards Turn Into Electrical Emergencies
A tree doesn’t have to touch a wire to cause a serious problem. Wind can push branches into the arc zone, where electricity jumps across air and ignites dry wood. Moisture on leaves or bark creates a path for current to travel and cause shorts. Fires also start when dry limbs overheat near high-voltage lines.
Electrical hazard prevention begins with pruning before branches ever reach the danger zone. Proper spacing prevents ignition and allows utility crews to work safely. Never trim near a live line yourself. Preventing these risks is part of responsible vegetation management.
Vegetation Management
Vegetation management is about more than just keeping limbs away from power lines. Utility crews also reduce fire risks, prevent property damage, and protect access for maintenance teams. They monitor tree growth patterns and schedule trimming before the onset of seasonal storms.
You should take the same approach at home. Annual inspections help control overgrowth, avoid costly removals and keep your property safe.
