How Long Does an Arborist Report Take to Complete?
Long Does an Arborist Report Take to Complete?
If you need arborist reports for a development project, council application, property purchase, or tree health assessment, one of the first questions you may ask is how long the process takes. The answer depends on several factors, including the size of the property, the number of trees involved, the purpose of the report, and how detailed the assessment needs to be.
While some arborist reports can be completed within a few days, others may require one to several weeks, especially when they involve complex inspections or additional research. Understanding the typical timeline can help you plan your project more effectively and avoid unnecessary delays.
In this guide, we will explain the different stages involved in preparing arborist reports, the factors that affect completion time, and how you can help speed up the process.
What Are Arborist Reports?
Arborist reports are professional documents prepared by qualified arborists after inspecting trees on a property. These reports provide valuable information about tree species, health, structure, safety, location, and recommendations for management or preservation.
Many councils, developers, homeowners, architects, and property managers rely on arborist reports when making decisions involving trees.
Typical information included in arborist reports includes:
Tree identification
Tree condition and health
Structural stability
Risk assessment
Tree protection recommendations
Development impact assessments
Maintenance recommendations
Removal recommendations when necessary
If you are unsure about the type of report you need, it helps to review a professional certified arborist report before arranging an inspection.
Typical Timeline for Arborist Reports
The entire process usually involves several steps rather than simply inspecting the trees.
Initial Consultation
Most projects begin with an enquiry where the arborist gathers information about your property and the purpose of the report.
This stage often takes less than one day and helps determine what type of assessment is required.
Scheduling the Site Inspection
The inspection appointment depends on the arborist’s availability.
During quieter periods, an inspection may be scheduled within a few days. During busy seasons, it could take one to two weeks before an available appointment.
Factors affecting scheduling include:
Current workload
Weather conditions
Property accessibility
Location of the property
On Site Tree Inspection
The inspection itself may take anywhere from thirty minutes to several hours.
A small residential property with only a few trees can often be completed quickly.
Larger commercial sites, schools, parks, or development sites may require several hours because each tree must be carefully assessed.
The arborist may record:
Tree measurements
Species identification
Signs of disease
Structural defects
Root conditions
Surrounding site conditions
Photographs
GPS locations where required
Writing the Report
After the inspection, the arborist compiles all collected information into a detailed report.
This stage usually takes between one and five business days depending on the complexity of the assessment.
For simple residential arborist reports, the report may be completed within two or three business days.
More detailed reports involving development applications or legal matters often require additional research and analysis.
Factors That Affect Completion Time
Not all arborist reports require the same amount of work. Several factors can influence how long the process takes.
Number of Trees
The more trees that need assessment, the longer both the inspection and report writing will take.
Inspecting five trees is much faster than assessing fifty trees across a large property.
Purpose of the Report
Different reports require different levels of detail.
Examples include:
Development applications
Construction planning
Tree risk assessments
Insurance claims
Tree preservation
Council requirements
Legal disputes
Reports supporting legal proceedings generally require more documentation than standard residential assessments.
Property Size
Large rural properties naturally require more inspection time than a typical suburban home.
Walking between trees, mapping locations, and documenting each specimen can significantly increase the overall timeline.
Tree Condition
Trees showing signs of disease, pest infestation, storm damage, or structural problems often require closer examination.
Additional testing or specialised assessment methods may sometimes be recommended.
Council Requirements
Some councils require reports that meet specific standards or include additional documentation.
Preparing reports that satisfy local planning requirements may add extra time before the final document is delivered.
Can Arborist Reports Be Completed Faster?
Sometimes clients need arborist reports urgently for building approvals, property settlements, or emergency situations.
Many arborists offer priority services depending on their workload.
You can help reduce delays by:
Providing accurate property information
Supplying site plans if available
Making all trees accessible
Explaining the report purpose clearly
Booking early before project deadlines
Having everything ready before the inspection allows the arborist to complete the assessment more efficiently.
You can also learn more about professional arborist consulting services before arranging an inspection so you know what information may be required.
What Happens After the Report Is Completed?
Once finished, the report is usually delivered electronically as a PDF.
You can then submit it to:
Local council
Architects
Builders
Engineers
Insurance companies
Property buyers
Legal representatives
If revisions are requested by the council or another organisation, the arborist may need additional time to update the report.
Why Quality Matters More Than Speed
While everyone wants fast service, accuracy should always come first.
A thorough inspection helps identify issues that could affect safety, development approval, or future tree health.
An incomplete report may result in:
Delayed approvals
Additional inspections
Extra costs
Incorrect recommendations
Safety concerns
Taking a little more time to produce a detailed report often saves time and money later in the project.
Planning Ahead
If your project has strict deadlines, it is always a good idea to organise arborist reports as early as possible.
Booking in advance provides more flexibility for inspection appointments and gives enough time for any follow up questions or revisions before submissions are due.
Early planning is especially important during busy construction seasons when qualified arborists may have fully booked schedules.
Conclusion
The time required to complete arborist reports varies depending on the size of the property, the number of trees, the purpose of the assessment, and the level of detail required. Simple residential reports may only take a few business days, while larger development or legal reports can take one or more weeks from inspection to final delivery.
Planning ahead and providing complete property information can help make the process smoother and reduce delays.
