You’ve got a consultation scheduled with an arborist, and you’re mentally preparing your questions — probably starting with price and how long they’ve been in business. What to ask a local Florida tree arborist actually starts somewhere most homeowners skip entirely: whether their certification would hold up if you ever needed it for something legal or financial. That’s the question that actually matters most, and here’s why.
Quick disclaimer before we continue: this reflects publicly available credential standards and statutory references as of the date above, not legal advice. Confirm any arborist’s current certification status directly with the issuing organization before relying on it.
What “Certified Arborist” Actually Means in Florida
Florida has no state-issued arborist license. “Certified Arborist” refers to a voluntary credential from the International Society of Arboriculture, which happens to be the exact standard Florida Statute 163.045 requires for legally valid tree risk documentation.
Here’s the part that surprises people: there’s no Florida state arborist license to check. Unlike a general contractor or an electrician, “arborist” isn’t a state-regulated title in Florida. What you’re actually looking for is ISA Certified Arborist status — a voluntary credential from the International Society of Arboriculture.
That “voluntary” label doesn’t mean it’s optional in every sense, though. Under Florida Statute 163.045, this exact credential — or a Florida-licensed landscape architect meeting the same standard — is what’s required for a tree risk assessment to legally satisfy the statute’s exemption documentation. So while nobody’s forcing an arborist to hold it, whether they do determines whether their opinion carries real legal weight or just a professional one.
Questions That Are Legally Consequential — and Questions That Are Just Good Practice
Ask These If You Might Ever Need Legal or Insurance Documentation
If a tree situation might involve a permit exemption, insurance claim, or liability question, ask specifically whether the arborist holds current ISA Certified Arborist status and follows the BMP Tree Risk Assessment protocol.
If there’s any chance you’ll need documentation that holds up — a permit exemption, an insurance claim, a liability dispute with a neighbor — these questions matter more than anything else on your list:
- “What’s your ISA certification number?” (You can verify it directly with ISA.)
- “Are you TRAQ qualified?” (Tree Risk Assessment Qualification — the specific training tied to the risk-assessment methodology.)
- “Will your assessment follow the BMP Tree Risk Assessment protocol?” (For full detail on what that process actually involves, see our tree hazard assessment guide.)
Ask These for General Peace of Mind
For routine tree work without legal stakes, general questions about insurance, references, and written estimates are useful but not legally consequential the way credential questions are.
For everyday trimming or removal work with no legal documentation riding on it, standard questions still apply: Do you carry insurance? Can I see references? Will I get a written estimate? What’s your cleanup process? These matter for a good experience — they just don’t carry the same weight as the credential questions above.
What Happens If You Skip These Questions
Hiring someone without verifying ISA certification means any assessment they provide typically won’t satisfy Florida Statute 163.045’s documentation requirement or hold up with an insurer.
Here’s the real cost of skipping the credential questions: if it turns out you needed documentation for a permit exemption or an insurance claim, and the person you hired wasn’t actually ISA certified or TRAQ qualified, their write-up likely won’t count. You’d be in the same position as having no documentation at all — a scenario covered in more detail on our tree hazard assessment page. Asking upfront costs nothing. Finding out afterward can cost you the exemption or the claim.
The Full List of Questions to Ask, Organized by Purpose
A complete arborist consultation covers twelve questions across credentials, assessment methodology, business basics, and tree-specific concerns — each one answered plainly before you decide to hire.
Here are all twelve questions worth asking, with a short note on why each one matters and what a good answer sounds like.
Credential Questions
1. What’s your ISA certification number, and is it current? Why it matters: Certification numbers are verifiable directly through ISA’s website. A real arborist will give you this without hesitation. Good answer: A specific number, offered readily, with an invitation to check it yourself.
2. Are you TRAQ qualified specifically, not just ISA certified generally? Why it matters: ISA certification and TRAQ qualification aren’t the same thing — TRAQ is the specific add-on training tied to formal risk assessment. Not every certified arborist holds it. Good answer: A clear yes or no, without conflating the two credentials.
3. If you’re not ISA certified, are you a Florida-licensed landscape architect? Why it matters: This is the only other credential that satisfies §163.045’s documentation standard. If the answer is no to both, their assessment won’t carry legal weight. Good answer: A direct license number you can verify with the state, or an honest “no” — which tells you their assessment is informational only.
Assessment-Process Questions
4. Will you follow the BMP Tree Risk Assessment protocol for this evaluation? Why it matters: This is the exact methodology behind any legally valid risk rating, not just a general opinion. Good answer: A confirmation they’ll conduct a structured inspection, not just a walk-around and a verbal impression.
5. Will I receive a written report, not just a verbal opinion? Why it matters: Verbal opinions can’t be submitted for a permit exemption or an insurance claim. Written documentation can. Good answer: Yes, with a sample report or a description of what it includes.
6. Will your report include a specific risk rating, or just a general recommendation? Why it matters: A proper TRAQ-based report produces a defined rating — Low, Moderate, High, or Extreme — not just “this tree looks concerning.” Good answer: Confirmation that the report will state a formal rating tied to the assessment methodology.
Business and Insurance Questions
7. Are you insured, and can you provide proof directly from your carrier? Why it matters: Verifying insurance yourself, rather than trusting a verbal claim, protects you if something goes wrong during the work. More on this in our licensed tree contractor guide. Good answer: A carrier name and phone number you can call directly.
8. Do you hold a current local business tax receipt? Why it matters: This is one of the few things Florida actually does require locally, even though there’s no state arborist license. Good answer: A straightforward yes, with the jurisdiction named.
Tree-Health and Removal-Specific Questions
9. What’s your diagnosis, in plain terms — what exactly is wrong with this tree? Why it matters: A vague answer like “it doesn’t look great” isn’t a diagnosis. You want specific, checkable findings. Good answer: Named symptoms — decay location, structural defect, species-specific concern — not a general impression.
10. Are there alternatives to removal, or is removal genuinely the only option? Why it matters: A trustworthy arborist should be able to explain why lesser options — pruning, cabling, monitoring — won’t work, not just recommend the most expensive service. Good answer: A specific explanation of why alternatives were ruled out, not just “removal is best.”
11. If this tree was damaged in a storm, has the internal structure been checked, not just the visible damage? Why it matters: Storm damage often hides internal weakening that a surface look misses. Good answer: Confirmation of a structural check, not just a visual pass on broken limbs.
12. If my HOA or neighbor disputes this removal, will your documentation hold up as independent evidence? Why it matters: Disputes happen. Documentation from a properly credentialed arborist is far more persuasive than a homeowner’s own account. Good answer: Confidence that their written report, tied to their credentials, stands on its own if challenged.
Recent Changes You Should Know About (2024–2026)
ISA periodically updates its certification categories and tree risk assessment forms, so confirming an arborist’s credentials are current rather than lapsed matters more than it used to.
ISA revises its certification structure and assessment forms from time to time — current forms in circulation reflect updates through 2025. An arborist who was certified years ago but hasn’t maintained continuing education requirements may hold a lapsed credential without mentioning it. Asking directly, and verifying independently with ISA, closes that gap.
When to Call a Professional
A proper consultation that covers credential verification, assessment methodology, and a clear diagnosis is exactly what a qualified hazardous tree assessment should include.
Everything covered above — credential verification, methodology, a clear written diagnosis — is what a proper consultation should look like. Our hazardous tree assessment service is built around exactly this standard, for anyone who wants documentation that will actually hold up if it’s ever needed.
FAQs: What to Ask a Local Florida Tree Arborist
Start with credential questions — ISA certification number, TRAQ qualification — then move to assessment methodology, insurance, and specific questions about your tree’s condition and recommended treatment.
It’s a voluntary credential from the International Society of Arboriculture. Florida has no state arborist license, but ISA certification is the specific standard Florida Statute 163.045 requires for legally valid documentation.
Not to work as an arborist generally. But if you need documentation for a permit exemption or insurance purpose, only an ISA-certified arborist’s or Florida-licensed landscape architect’s assessment will satisfy that requirement.
Ask for their diagnosis in plain language, whether alternatives to removal exist, and why removal is being recommended specifically rather than a less drastic option.
Ask what specific signs led to their assessment, how the condition is likely to progress, and what monitoring or treatment options exist short of removal.
A thorough inspection should cover the crown, trunk, and root collar for defects, along with a clear explanation of findings — ideally following the BMP Tree Risk Assessment protocol if any documentation is needed.
No. Only a report from an ISA-certified arborist or Florida-licensed landscape architect, following the required risk assessment protocol, satisfies the statute’s documentation standard.
There’s no state law specifically mandating it, but it’s standard practice and worth verifying directly with their insurance carrier before hiring.
A proper estimate should detail the scope of work, timeline, and cost. For a broader look at tree removal pricing in Florida, see our tree removal cost guide.
Final Word
The question that actually protects you isn’t “how much do you charge” — it’s “are you ISA certified, and will your assessment hold up if I need it.” Ask that first, verify the answer independently, and the other eleven questions on this list will fill in everything else you need to hire with confidence.
