Arborist Consultation in San Francisco
Objective Tree Assessments and Written Reports by a Registered Consulting Arborist

Our consulting services are led by a Registered Consulting Arborist (ASCA) and provide homeowners with clear, defensible guidance for safety, property protection, and informed decision-making.
Professional Tree Consulting • Reports • Expert Analysis
At Arborist Now, we provide professional arborist consultation services for homeowners throughout the San Francisco Bay Area. Our consulting division operates independently from routine tree service work and delivers unbiased, expert evaluations supported by detailed written reports.
Unlike a complimentary estimate or site visit, an arborist consultation is a stand-alone professional service. It provides an impartial assessment of your trees using industry standards, field diagnostics, and decades of local experience.
What's in an arborist report?
An arborist report is a written, signed document recording what was found and what it means. Length depends on scope — a single-tree risk assessment runs a few pages; a construction impact evaluation across a whole site runs considerably longer. What every Arborist Now report contains:
- Tree inventory. Species, size, location, and condition of each tree in scope.
- Findings. What was observed — structural defects, decay, pest or disease presence, root and soil conditions.
- Methodology. Which standard was applied. Risk assessments use ISA TRAQ; appraisals use CTLA methods. Naming the standard is what makes a report defensible.
- Photographs. Documented site conditions at the time of inspection.
- Recommendations. Specific, prioritized actions rather than general advice.
- Credentials and signature. Signed by the arborist who performed the assessment, with certification numbers.
Most reports are delivered within a week of the site visit. If you are working to a permit deadline or a legal filing date, say so when you book — we schedule around it.
What is an Arborist Consultation?
An arborist consultation is an on-site evaluation performed by a certified expert trained in tree biology, risk assessment, and urban forestry. It produces a written document you can hand to a city planner, an insurance adjuster, an attorney, or a buyer — which is the difference between a consultation and a quote.
During a consultation, your consulting arborist inspects tree structure, health, and growth patterns; identifies pests, disease, or environmental stress; evaluates root systems and soil conditions; assesses safety risk and likelihood of failure; and records objective findings and recommendations.
Arborist Now’s consulting work is deliberately separate from the crews who do removals and pruning. An assessment written by someone with no stake in selling you the work is the only kind worth paying for.

When to Request a Consultation
Most people call Arborist Now for a consultation because someone has asked them for a document — a city planner, an insurer, a lawyer, or a buyer’s agent. The rest call because they need an answer they can trust from someone who is not also quoting them for the work. Both are good reasons.
- Planning construction or landscaping near existing trees.
- Noticing decline, dieback, or pest activity.
- Facing a boundary or neighbor dispute.
- Preparing permit applications or city documentation.
- Filing or defending an insurance claim.
- Purchasing property with mature or protected trees.
- Seeking an expert opinion before major tree work.
Our Process
- Scope Definition – Define goals and determine required evaluation.
- Site Assessment – On-site inspection and data collection.
- Analysis & Reporting – Findings evaluated using ISA and ASCA standards.
- Recommendations – Clear management or mitigation measures.
- Implementation & Monitoring – Optional execution or monitoring by Arborist Now.
What does an arborist consultation cost?
A consultation is a professional service with a fee, not a free estimate. That is the point — you are paying for an assessment nobody has a financial interest in skewing. What determines the fee:
- Scope. A single tree is a different job from a full property survey or a construction site evaluation.
- Report type. A TRAQ risk assessment, a CTLA appraisal, and a construction impact evaluation each require different analysis and documentation.
- Turnaround. Standard delivery is about a week. Compressed timelines for permit or filing deadlines can be accommodated.
- Legal involvement. Expert witness work and litigation support are quoted separately from standard reporting.
Call Arborist Now with what you need the report for and we will tell you the scope and the fee before scheduling. If it turns out you do not need a formal report, we will say that too.

Frequently Asked Questions
Is the consultation included with a free estimate?
No. An Arborist Now consultation is a paid professional service, separate from a routine estimate. An estimate tells you what work would cost; a consultation tells you what is actually happening with your tree and produces a written report you can use with a city, an insurer, or a court.
Can you prepare reports required by cities?
Yes. Arborist Now regularly produces permit and compliance reports for Bay Area jurisdictions, written to the documentation standards those agencies require.
Can you also perform the recommended work?
Yes. Arborist Now’s operations team can carry out the recommendations if you want us to — but the consulting arborist who writes the assessment is separate from the crews who would do the work, so the recommendation is not a sales pitch.
Do you offer expert witness services?
Yes. Arborist Now’s Registered Consulting Arborist provides expert testimony and legal reporting for property disputes, damage claims, and litigation.
What is a tree risk assessment?
A tree risk assessment evaluates how likely a tree is to fail, what it would strike, and how severe the consequences would be. Arborist Now performs these to ISA TRAQ standards, which produce a defensible risk rating rather than an informal opinion. It is the assessment most often required by insurers and used in neighbor disputes.
