How Tree Failures Create Legal Risk for Property Owners

Healthy trees add value and curb appeal to your commercial property. But when a tree is stressed, neglected, or beginning to fail, it becomes a safety hazard and liability concern. In this guide, we explain how tree failures create legal risks for property owners, review the most common causes of commercial tree hazards, and outline practical steps you can take to reduce your risk.

The Legal Risks Caused by Sick, Unstable, or Overgrown Trees

Unhealthy trees can create serious liability issues if left unaddressed. A weak branch might fall and injure a visitor or damage property. Uplifted roots can crack pavement and cause someone to trip. Overgrown limbs may block lighting or signage, creating unsafe conditions at night. These hazards tend to develop gradually, so they are often overlooked until an accident occurs. At that point, the property owners and managers may be held responsible.

To stay ahead of these risks, schedule regular tree inspections with a certified arborist who can identify both obvious and hidden hazards. Keeping records of your inspections and maintenance also helps limit your liability in the event of an accident.

What Causes Trees to Become a Hazard?

A variety of site conditions and maintenance issues can compromise tree health and stability. Here are some of the most common causes of tree-related hazards:

• Storm damage: High winds can snap branches, break limbs, and even split tree trunks. Heavy rain and saturated soil weaken root systems, making trees more likely to lean or uproot.

• Infrequent pruning: Leaving weak or diseased branches in tree canopies increases the chance of limb failure, pests, and plant diseases. These hazards can be reduced with routine tree care.

• Mechanical damage: Damage from lawn equipment, vehicles, or construction activities can injure tree trunks and roots, opening pathways for pests and decay.

• Soil compaction: Frequent foot traffic or vehicle use around trees compresses the soil, limiting root access to air and water.

• Planting and placement: Planting trees close to structures, pathways, or other trees can restrict growth, slow down root development, and lead to poor stability. Improper tree selection can also create hazards on your property.

• Pest or disease infestation: Untreated bacterial infections, fungal growth, or unchecked insect populations can cause internal damage that makes branches more prone to breaking.

Who Is Responsible for Tree Failures?

As a rule of thumb, if the trunk sits on property you manage, you are responsible for inspecting the tree and addressing hazards before they lead to damage or injury. Complications can arise when the risk crosses onto neighboring land, involves shared spaces, or sits near utilities. Here are some common situations you might encounter as a property manager:

• Trees overhanging your property: If the trunk is on neighboring land but branches or roots extend onto your side, document your concerns and notify the neighboring owner in writing. You may have the right to prune branches up to the property line, but always check local regulations first.

• Trees near power lines or utilities: When you see a tree close to or touching a power line, report it to the utility provider right away. Keep copies of all correspondence, and allow only licensed professionals to manage your trees in these situations.

• Trees in shared or HOA-managed areas: Review governing documents and maintenance agreements to clarify responsibility for inspections, pruning, and removals. In most cases, the HOA is responsible for trees in common areas, while individual owners are responsible for trees within their lots.

*If you are unsure about local or regional regulations, seek guidance from legal counsel and a certified arborist.
