Do You Need an Arborist Report to Remove a Hazardous Tree in Florida?

One of the most common tree-law questions in Florida sounds simple, but it almost never stays that way:

Do I need an arborist report to remove a hazardous tree?

A lot of homeowners hear a short version of the answer and stop there. Someone says Florida law lets you remove dangerous trees on residential property without a permit. Someone else says you need an arborist report no matter what. Another person says a contractor’s opinion is enough. Those answers get mixed together until the owner is left with the worst kind of legal guidance: confident, incomplete, and probably wrong.

The practical answer is this:

In the specific residential risk-based framework of Florida Statute 163.045, proper documentation is central. But outside that exact framework, local rules and property context can still matter.

Why this question gets misunderstood

Homeowners usually blur together three different questions:

• What does state law allow in certain hazardous-tree situations?
• What kind of documentation does that state-law pathway require?
• What happens if my property or my tree does not fit that exact statutory framework?

Those are not the same thing.

A homeowner may correctly hear that some residential hazardous-tree removals do not require a local permit if the statute is satisfied. But if the homeowner never checks whether the statute actually applies—or what the statute means by documentation—they can make a very expensive mistake.

What Florida Statute 163.045 actually says about documentation

The 2025 Florida Statutes define “documentation” for purposes of section 163.045 as an onsite assessment performed in accordance with the tree risk assessment procedures outlined in Best Management Practices - Tree Risk Assessment, Second Edition (2017) by an arborist certified by the International Society of Arboriculture (ISA) or a Florida licensed landscape architect, and signed by that certified arborist or licensed landscape architect. The statute also says a local government may not require notice, application, approval, permit, fee, or mitigation for the pruning, trimming, or removal of a tree on residential property if the owner possesses documentation from one of those professionals that the tree poses an unacceptable risk to persons or property. citeturn340104search1turn340104search3

That is a much more specific requirement than “someone looked at the tree and said it was dangerous.”

So do you need an arborist report?

Under the section 163.045 residential statutory-exemption pathway, you need the kind of documentation the statute describes.

That means the practical answer is often yes: you need an onsite, signed risk assessment from the type of professional the statute recognizes if you want to rely on that specific state-law protection. Tampa’s published explanation of the statute says the documentation must include an onsite assessment and a signature from a certified arborist or Florida-licensed landscape architect, and warns that if those elements are missing, a notice of violation may be issued. citeturn150084search9turn150084search1

So while homeowners often use the phrase arborist report, the safer way to say it is:

You need the exact kind of signed onsite risk documentation the statute requires if you want to rely on section 163.045.

Why “hazardous” is not just whatever the owner says it is

This is another major misunderstanding.

The statute does not revolve around casual homeowner opinion. It revolves around whether the tree poses an unacceptable risk, and it ties that concept to the tree-risk assessment procedures in the cited best-management-practices framework. It also defines “unacceptable risk” as a situation where removal is the only means of practically mitigating the risk below moderate. citeturn340104search1

That is why a tree that feels messy, inconvenient, too shady, or even generally worrying to the owner is not automatically the same thing as a tree that meets the statutory standard.

Why “arborist report” and “local permit” are not always the same conversation

This is where homeowners get tripped up.

They hear that an arborist report matters and assume the report always replaces the permit. That is only true if the property and tree actually fall within the section 163.045 framework.

If they do not, the local city or county may still regulate the tree through ordinary permit, protected-tree, or preservation rules. Tampa’s tree resources and self-certified arborist materials show how local systems can still require risk assessments and arborist reports in city permitting contexts for protected, specimen, and grand trees, and for pruning permits in some circumstances. citeturn150084search17turn150084search7

That is why the homeowner’s real question should be:

Am I using the state-law residential exemption, or am I in a local permit framework where documentation is still part of the city process?

The property type matters

Section 163.045 defines “residential property” in a specific way: a single-family, detached building on a lot actively used for single-family residential purposes that is either a conforming use or a legally recognized nonconforming use under local land-development regulations. citeturn340104search3

That means homeowners should not casually assume the statute works the same way for:

• multifamily sites
• commercial property
• common HOA areas
• nonconforming property situations they have not verified
• other landscapes outside the statute’s defined residential setting

The cleaner the homeowner thinks the answer is, the more important that definition becomes.

Why mangroves are not part of this shortcut

This deserves its own reminder.

Section 163.045 specifically says it does not apply to delegated mangrove protection authority. So if mangroves are involved, the hazardous-tree exemption conversation changes entirely. citeturn340104search1turn340104search7

That is why owners should never use the ordinary hazardous-tree documentation logic as a substitute for the mangrove rules.

A common mistake: thinking a tree company’s verbal opinion is enough

A contractor may have real field experience, but that is not the same thing as the signed documentation the statute describes.

If the owner plans to rely on section 163.045, the safer standard is not:

“A crew told me the tree was bad.”

It is:

“I possess the onsite signed documentation from the kind of professional the statute names.”

That difference matters a lot if the removal is later questioned.

Another common mistake: assuming documentation is optional if the tree obviously looks dangerous

Sometimes the tree really does look terrible.

Even then, homeowners should be careful. The point of the documentation is not to create bureaucracy for its own sake. It is to connect the removal to the statutory standard in a way that can be defended later if needed.

The more obvious the danger feels, the more important it may actually be to document it correctly rather than rely on memory and confidence.

What homeowners should verify before relying on the report

Before removing a hazardous tree under the state-law framework, verify:

• that the property fits the statute’s residential-property definition
• that the documentation is based on an onsite assessment
• that the assessment follows the statute’s referenced tree-risk framework
• that the document is signed by an ISA-certified arborist or Florida licensed landscape architect
• that the tree truly poses the kind of unacceptable risk the statute describes
• that the situation does not involve mangroves or another separately regulated category

These questions matter much more than “Do I have a paper?”

Why local interpretation still matters in the real world

Even when the state-law pathway exists, local governments and code-enforcement systems may still scrutinize whether the owner actually qualified for it. Tampa’s public guidance makes that practical point very clearly by emphasizing the need for both onsite assessment and proper signature, and by explaining that deficiencies can lead to a notice of violation. citeturn150084search9turn150084search1

That is why homeowners should think in terms of meeting the standard, not just possessing a document with a title on it.

A practical mindset for homeowners

The safest way to approach a hazardous-tree removal is:

1. determine whether the property fits section 163.045
2. determine whether the tree truly presents the kind of unacceptable risk the statute contemplates
3. obtain the exact type of signed onsite documentation the statute requires if relying on that pathway
4. do not assume local permit rules disappear unless the statutory conditions are actually met
5. remember that outside this framework, city or county tree rules may still apply

That is slower than guessing—but much cheaper than defending the wrong removal later.

Final takeaway

Do you need an arborist report to remove a hazardous tree in Florida?

If you are relying on the residential statutory-exemption pathway in section 163.045, you need the specific kind of signed onsite documentation the statute requires from an ISA-certified arborist or Florida licensed landscape architect. Tampa’s own public interpretation reinforces that this documentation is not optional under that pathway. But if the property or tree falls outside that exact framework, local rules may still control how removal is handled. citeturn340104search1turn340104search3turn150084search9turn150084search17

The best rule of thumb is simple: do not ask only whether you need a report. Ask whether you are actually in the statutory pathway that makes that report the key to removing the tree without local permit review.
