Tree Service Contractors Insurance Requirements in North Dakota

Tree work is consistently one of the most hazardous occupations, with OSHA fatality rates far exceeding most construction trades. The combination of working at height, chain saw operations, and unpredictable tree behavior creates extreme injury severity. Property damage potential is also extreme — a tree falling on a structure, vehicle fleet, or power line can cause hundreds of thousands of dollars in damage in seconds.

Require ISA (International Society of Arboriculture) Certified Arborist credentials for the crew supervisor and TCIA (Tree Care Industry Association) accreditation for the company. These certifications indicate proper training in tree biology, pruning standards, rigging, and safety. Insurance carriers often provide better rates and broader coverage to ISA-certified companies, so certification is also an indicator of better insurance quality.

OSHA requires a minimum 10-foot clearance from power lines for all workers and equipment. Tree work within 10 feet of power lines must be performed by line-clearance tree trimmers classified under WC code 2702. The local utility company should be notified before any tree work near their lines, and de-energization may be required. Never allow a non-line-clearance tree company to work near power lines — the liability exposure is extreme.

If a tree service contractor drops a limb onto your neighbor's property, the contractor's GL policy should be the primary source of coverage. However, as the property owner who hired the contractor, you may also face claims from the neighbor. This is why additional insured status on the tree service contractor's GL policy is essential — it extends coverage to you for claims arising from the contractor's work. Document the scope of work and tree conditions before work begins.

Licensing requirements for tree service contractors vary by municipality in North Dakota. Check with your local licensing board and always request proof of current licensure on the COI.

In North Dakota, you as the property manager could be held liable for injuries or damages caused by an uninsured tree service contractors on your property. North Dakota courts have consistently ruled that property owners have a duty to verify contractor insurance before allowing work to begin.
