If you own property, you are responsible for keeping the trees healthy and reducing safety risks. That’s a hefty job, often with formal rules or regulations you need to follow. You may need to get a professional arborist report for legal, insurance, or general tree care purposes.
In this blog post, we’ll demystify what an arborist report is, when it’s necessary, and what to expect from your report.
What is an Arborist Report?

An arborist report is a detailed assessment of your trees’ health and safety risks by a professional arborist. It covers signs of disease, damage, pests, structural weaknesses, soil conditions, potential hazards, and more. This comprehensive document serves as a reference point for tree care and management.
You may need an arborist report for:
- Property development concerns
- Insurance claims
- Legal disputes
- Assessing the trees’ health
When to Get an Arborist Report
It’s a good idea to have regular tree inspections for tree health and safety reasons. However, it’s even more important to have a formal arborist report in the following situations:
Construction and Development

Before you begin construction or development work on your property, you must assess tree-related risks. Trees can sometimes restrict whether, where, and how you can build on your property.
An arborist report will tell you how to protect both the trees and the new building during the process. It will also check your compliance with local regulations.
Insurance and Legal Purposes
Trees can fail anytime, but they’re more likely to fail if they are diseased or unhealthy. As a result, tree care is a factor in insurance claims and benefits.
If a tree causes property damage or a dispute with your neighbors, an arborist report can provide an unbiased and expert evaluation. It can support your insurance claims or legal proceedings.
Tree Health and Hazard Assessment

If you notice signs of decline in your trees, such as dead branches, discoloration, or pest infestations, you may want to get their health assessed. A complete arborist report will pinpoint the issues and recommend a treatment plan.
Tree Appraisals
Trees can factor into the value of your property. If you plan to buy, sell, or insure your property, you may want to get an arborist report.
What to Expect in Your Arborist Report

A well-prepared arborist report will usually cover the following points:
- Tree Identification: A list or mention of each tree in the assessed area and its species.
- Health and Condition: An assessment of each tree’s overall health, noting any diseases, pests, or stress factors.
- Structural Integrity: An evaluation of the trees’ structural integrity, with notes about any weak branches or potential hazards.
- Risk Assessment: Notes about any trees that may pose a danger to property or human safety.
- Recommendations: Formal recommendations for tree care, such as pruning, fertilization, or pest control.
- Compliance and Regulations: If your report is required for a construction project, it will address compliance with local regulations. It may provide guidelines for tree protection and safety during construction.
An arborist report is a tool that empowers you to make informed decisions about the trees on your property. Whether you’re planning a construction project, buying insurance, concerned about tree health, or facing a tree-related legal issue, an arborist report offers invaluable insights and recommendations.
