Commercial Tree Maintenance: Liability, Safety, and Property Value

Trees on commercial properties create value but also liability. Here's how to manage them responsibly.

Commercial Property Services

Trees on commercial properties enhance aesthetics, provide shade, and contribute to property value. They also create liability if poorly maintained. Balancing these considerations requires an active tree management program.

Annual arborist inspections identify structural defects — dead branches, co-dominant stems, root damage, fungal disease — that create failure risk. Documented inspections are your evidence of due diligence when a tree failure causes damage or injury.

Industry Best Practices

Dead branches and dead trees are the highest liability items. Dead wood falls without the warning a structurally compromised living tree might provide. Prompt removal of dead material is non-negotiable from a safety perspective.

Root systems cause pavement problems. Tree roots grow toward water and oxygen, often under pavements. Root growth causes heaving and cracking in concrete and asphalt. Root barriers during new paving installation can redirect roots.

How D&D Commercial Services Can Help

Proximity to buildings matters. Trees too close to building foundations create root intrusion risks; those with branches over the roof create debris and potential storm damage risk. Maintain appropriate clearance zones.

Municipal tree protection bylaws apply to trees above specified diameter thresholds, including on private property in many Ontario municipalities. Removing protected trees without a permit can result in significant fines.

Tree maintenance documentation — inspection reports, work orders, and completion records — creates the paper trail that demonstrates proactive management. In a claim arising from tree failure, documented management history is your defence.
