Do You Need an Arborist License in Florida?

Last updated: August 23, 2026

Florida does not license arborists — and as of 1 July 2025 most of the county licenses that used to fill the gap are gone too. There is no DBPR or FDACS arborist credential. And F.S. 163.211(2)(a) expired local occupational licenses that were imposed before January 2021, which is what ended the county tree-trimmer certificates. But there is one place where a credential carries real legal weight: mangroves. An ISA Certified Arborist automatically counts as a Professional Mangrove Trimmer.

What Florida Actually Requires

• No state arborist or tree service license. Neither DBPR nor the Department of Agriculture and Consumer Services licenses arborists, tree services or tree trimmers.
• Local licenses largely expired 1 July 2025. Under F.S. 163.211(2)(a), local government occupational licenses imposed before 1 January 2021 expired on that date. Under (2)(b) local licensing survives only where authorized by general law, and under (4) unauthorized local licensing “does not apply and may not be enforced.”
• A local business tax receipt from your county or city to operate — that is a tax registration, not an occupational license, and it is unaffected by the preemption.
• Professional Mangrove Trimmer status if you touch mangroves — see below. This one is real, and it is state law.
• ISA Certified Arborist is voluntary for ordinary tree work, but see the mangrove rule: in Florida it is the credential that unlocks a regulated activity.

What It Costs

Item	Cost	Notes
State arborist license	None — does not exist	No DBPR or FDACS credential for tree work
County tree-trimmer license	Largely gone since 1 July 2025	F.S. 163.211(2)(a); check your county for a general-law carve-out
Local business tax receipt	Varies by county/city	A tax registration, not an occupational license
ISA Certified Arborist	Paid to ISA	Voluntary — but it is what confers automatic PMT status
Professional Mangrove Trimmer	Automatic for ISA arborists	Others apply with 10 permitted projects and a notarized statement
Florida LLC	$125	Articles of organization + registered agent, filed at Sunbiz

No License to Get — but Mangroves Are a Different Matter

Two things changed the answer to this question, and most guidance online still has the old one.

First, the county licenses went away. Florida preempted occupational licensing to the state. F.S. 163.211(2)(a) let local governments keep licenses they had imposed before 1 January 2021 — but only until 1 July 2025, when those expired. Subsection (3) had already barred them from adding requirements or modifying the license in the meantime, and subsection (4) says unauthorized local occupational licensing does not apply and may not be enforced. That is the actual legal basis behind the county tree-trimmer certificates being retired — not a tree-specific law. The carve-out in (2)(b) is real though: local licensing survives where authorized by general law, so ring your county rather than assuming.

Second, and this is the part worth knowing: mangroves are separately regulated, and ISA certification is the key. Under the 1996 Mangrove Trimming and Preservation Act (F.S. 403.9321–403.9334), a Professional Mangrove Trimmer may supervise or conduct mangrove trimming, with qualifying work proceeding without permits. And ISA Certified Arborists are automatically considered PMTs — no application, no further action.

So in Florida the voluntary credential has teeth that it does not have in, say, California. If you work anywhere near the coast, ISA certification is not a nice-to-have on a business card — it is what lets you do mangrove work at all without going through the application route. Others can qualify by submitting 10 completed, permitted mangrove projects, demonstrating they can identify mangrove species, and providing a notarized sworn statement. Florida-licensed landscape architects, Society of Wetland Scientists certified professionals, ABCEP members and ESA certified ecologists also qualify automatically.

How to Get Licensed, In Order

1. Stop looking for a state arborist license — Florida does not issue one.
2. Check your county anyway. Most local tree-trimmer licenses expired 1 July 2025 under F.S. 163.211, but licensing authorized by general law survives.
3. Get a local business tax receipt from the county or city you operate in.
4. If you will work on or near mangroves, get ISA certified — it makes you a Professional Mangrove Trimmer automatically. Otherwise plan the 10-project application route.
5. Register the entity so the contract, the insurance certificate and the bank account sit behind a company.
6. Bind liability cover before the first job. Nothing in Florida law requires it, which is precisely why clients ask for the certificate instead.

Staying Licensed

With no state license there is nothing to renew at state level and no continuing education requirement. What does need attention: your local business tax receipt renews on the county or city cycle, ISA certification carries its own CEU requirement (and in Florida it is what sustains your automatic Professional Mangrove Trimmer status), and your liability cover has to stay in force because clients — not the state — are the ones checking.

Frequently Asked Questions

Do you need a license to be an arborist in Florida?

No. Florida issues no general state arborist or tree service license — neither DBPR nor the Department of Agriculture and Consumer Services lists one. Since July 1, 2025, most county and city tree-trimmer licenses have gone too: F.S. 163.211(2)(a) expired local occupational licenses that were imposed before January 1, 2021.

Did Broward County stop requiring a tree trimmer license?

That change traces to F.S. 163.211, not to a tree-specific law. Local occupational licensing was preempted to the state, and grandfathered local licenses — those imposed before January 1, 2021 — expired on July 1, 2025. Local licensing survives only where it is authorized by general law, and under subsection (4) unauthorized local licensing does not apply and may not be enforced. Check your own county before assuming, since the general-law carve-out is real.

Does ISA certification mean anything legally in Florida?

More than in most states. Under the 1996 Mangrove Trimming and Preservation Act, F.S. 403.9321–403.9334, an International Society of Arboriculture certified arborist is automatically considered a Professional Mangrove Trimmer, with no application required. PMT status authorizes mangrove trimming work and exempts qualifying activities from permitting.

What is a Professional Mangrove Trimmer in Florida?

A state designation under the Mangrove Trimming and Preservation Act allowing an individual to supervise or conduct mangrove trimming, with certain work proceeding without permits. ISA certified arborists, Society of Wetland Scientists certified professionals, Academy of Board Certified Environmental Professionals members, Ecological Society of America certified ecologists and Florida-licensed landscape architects all qualify automatically. Everyone else applies with 10 completed permitted mangrove projects, proof they can identify mangrove species, and a notarized sworn statement.
