On unincorporated Amelia Island, live oaks are protected by Nassau County's tree ordinance, and the biggest ones get the strictest treatment. A healthy tree of at least 5 inches in diameter counts as protected, a live oak of 40 inches or more is a specimen tree, and removing either one takes a permit unless a narrow exemption applies. This guide walks through what those terms mean, how close you can build, how to protect roots, and where to apply. Rules change, so confirm the details with the County before you act.
TL;DR
- Nassau County treats a healthy, non-invasive tree of at least 5 inches DBH (diameter at breast height) as protected on unincorporated Amelia Island, and a live oak of at least 40 inches DBH as a specimen tree.
- Removal needs a permit and a just cause, such as a hazard or new development. Aesthetics do not qualify. Ordinary pruning and minor maintenance generally do not need a permit.
- When you build, the protection zone around a retained tree is six times its DBH, with a 6-foot minimum. Nothing gets built, dug, stored or parked inside it.
- Florida law lets owners of qualifying single-family homes remove a tree that carries documented, unacceptable risk without local permits or replanting.
- Start with the County Arborist before you design, not after.

What the rules mean by a "protected tree"
Nassau County's Section 37.02 defines a protected tree on unincorporated Amelia Island as an existing, healthy, non-invasive tree measuring at least 5 inches DBH, as determined by an approved ISA-certified arborist. That threshold is lower than many owners expect. A young oak you planted a decade ago may already qualify.
DBH is measured at roughly chest height. Wrap a tape around the trunk, divide the circumference by 3.14, and you have a working number. The County's decisions rest on an arborist's measurement, so treat your own tape as a first pass.
Specimen live oaks
The same ordinance defines a specimen live oak as a healthy Quercus virginiana or Quercus geminata measuring at least 40 inches DBH, or a multi-trunk live oak whose trunks add up to at least 60 inches. These are the trees that give the island its cathedral-like lanes, and the County says as much in its legislative rationale: mature live oaks are integral to the health and distinctive character of Amelia Island's maritime forest. The ordinance therefore prioritizes retention and expects design alternatives to be considered before a specimen is removed.
Which jurisdiction applies to you
Section 37.02 covers unincorporated Amelia Island. Parcels inside the City of Fernandina Beach follow the city's own rules. Nassau County itself points owners with city, county-road, utility or state-road tree conflicts toward the right agency for each case: Florida Public Utilities, the City of Fernandina Beach, the County Road Department or FDOT. Confirm your parcel's jurisdiction first, because everything below depends on it.
Do you need a permit to remove or prune a live oak?
Removal
Protected-tree removal requires a permit, subject to listed exemptions. Specimen-tree removal asks for more: a Planning Department permit, a signed and notarized report from an ISA-certified arborist, a replacement plan, and review by the Nassau County-Amelia Island Tree Commission (NC-AITC) at a public hearing, all laid out in Section 37.02.

The County's tree removal application page is blunt about the test: applications are approved only for just cause, such as a hazardous tree or new development. Aesthetic concerns, such as wanting more sun or a cleaner lawn, are not a valid reason.
Pruning and maintenance
The same page states that pruning and minor maintenance generally do not require a permit, but the work must follow ISA and ANSI A300 tree-health standards. In practice that means no topping, no stripping the canopy, and no heavy cuts that stress an old oak. Hire a certified arborist for anything above a light trim. A live oak can survive a bad cut, but it rarely forgets one.
The state hazard exception
Florida adds a statewide rule that sits above local ordinances. Under Florida Statutes §163.045, a local government may not require notice, application, approval, permit, fee or mitigation for pruning, trimming or removing a tree on qualifying single-family residential property when the owner holds signed documentation from an ISA-certified arborist or a Florida-licensed landscape architect that the tree poses an unacceptable risk.
"Unacceptable risk" has a specific meaning. Removal must be the only practical way to bring the tree's risk below moderate under the 2017 ISA tree risk assessment procedures the statute names. A compliant removal also cannot trigger a replanting requirement.
Three practical points follow:
- The documentation comes from a credentialed professional, not from a neighbor's worry or your own judgment.
- The exception is for qualifying single-family residential property, so check that your lot fits.
- Nassau County asks owners with a dangerous residential tree to submit the arborist's risk assessment to treeinfo@nassaucountyfl.com, which keeps your file clean.
When a tree really is failing and the site is tight, such as a crown hanging over a roof, professional hazardous tree removal uses sectional dismantling and controlled lowering so the work does not damage the house or neighboring trees. Ask any crew you hire for proof of insurance and ISA certification.
What an unauthorized removal can cost
The penalties matter because live oaks cannot be replaced in a lifetime. Working-group minutes from March 2021 record a proposed penalty of up to $15,000 for unauthorized removal or fatal damage to a healthy specimen tree, to be set by the Code Enforcement Board. That was a proposal during drafting, so ask the County for the penalty schedule in force today. The safer reading is simple: a permit costs far less than a violation.
How close can a live oak be to a house?
There is no single magic distance, but the County gives you a formula. Its ordinance summary sets the protection zone at six times the tree's DBH, with a 6-foot minimum. Inside that zone, buildings, paving, digging, storage and vehicle parking are prohibited. The County also requires protection from injury to roots, trunk and branches, from grade changes and excavation, and from root compression.
The summary gives two examples:
| Tree DBH | Protection zone |
|---|---|
| 10 inches | 6 feet (the minimum) |
| 20 inches | 15 feet |
Apply the formula to a specimen live oak and the scale becomes clear. At 40 inches DBH, six times DBH is 240 inches, or 20 feet in every direction. That is a circle 40 feet across that your plans must leave alone. Treat these as the numbers for planning and let the County Arborist confirm how they apply to your lot.
Live oak roots spread far wider than the trunk suggests, mostly in the top foot or two of soil. That is why grade changes hurt as much as trenches do. Adding fill over the root zone can suffocate an old oak slowly, and the decline may not show for years.

Building or renovating near a live oak
The County's requirements for new development and major renovation, adopted in August 2021 and effective February 2022, follow a clear sequence, as summarized in its ordinance summary:
- Survey the trees. You need surveyed tree data, plus a tree protection and replacement plan.
- Run the numbers. Mitigation or preservation calculations show what you keep and what you replace. New development must preserve 100% of protected-tree DBH outside construction and disturbance zones and mitigate 25% of the protected-tree DBH removed within those zones.
- Barricade before work starts. Barricades go up around retained trees before any development activity.
- Keep the zone clear. No construction or storage inside protection zones.
- Go under, not through. Where trenching or excavation in a zone is deemed necessary by the county engineer, directional boring or tunneling is required.
For sitework on Amelia Island, the County's permit form requires a Planning Department site inspection before clearing, to verify that tree-protection barricades are in place. Do not let a clearing crew mobilize before that inspection.
Design habits that protect an oak
The best protection happens on paper. A few habits that work well with the County's rules:
- Locate the tree on the survey before you sketch the house, then shape the footprint around the protection zone.
- Route utilities, drainage and irrigation outside the zone from the start, so boring is the exception.
- Choose piers or a lighter foundation near the edge of a zone only if the County Arborist agrees.
- Name a single person on site who owns the barricades and can stop a delivery truck from parking under a canopy.
- Keep a photo record of barricades through construction.
For a broader view of land, approvals and design, our guide to building on Amelia Island covers how these steps fit together.
Are there downsides to owning a live oak?
Not many that careful planning cannot handle. A mature oak sheds leaves in spring, drops limbs now and then, and sends roots where it pleases. The answer is to site structures wisely, prune to standards, and have a certified arborist look at the tree periodically, especially after major storms. An oak that is understood and maintained is an asset, one that shades your home, frames your view and holds value that no nursery can supply.
Where to apply and who to contact
The County's tree removal application page sorts submissions by tree type:
| Situation | Where to send it |
|---|---|
| Protected-tree removal application | treeinfo@nassaucountyfl.com |
| Specimen-tree or canopy-road application | planning@nassaucountyfl.com |
| Residential tree that presents a danger (arborist risk assessment) | treeinfo@nassaucountyfl.com |
The County Arborist reviews applications within two weeks. The Nassau County-Amelia Island Tree Commission was created to protect and improve the urban forest in unincorporated Amelia Island, and it reviews restoration plans and administrative appeals under Section 37.02. Check the County's pages for current forms, meeting schedules and fees.
Preservation as a community value
Tree protection on Amelia Island is part of a larger idea: that growth here should leave the island recognizable. We explore that in why Amelia Island avoids overdevelopment and in our guide to maritime forest communities, which looks at how coastal stewards keep forests intact while people live among them.
Our perspective
We have always believed that a home should feel woven into the land rather than set on top of it. On Amelia Island, nothing makes that case better than a live oak. Its limbs make a porch feel like a true living room, and its shade is the original architecture of this coast.
At Crane Island, we preserve nearly half our land as open space, with marshlands and forests left in their natural state, and we hold our homes to rigorous architectural standards inspired by Lowcountry tradition. With only 14 homesites, every build can begin with the trees, not end with them. That is how legacy-minded homes get designed: the oak sets the terms, and the architecture answers.
We would encourage any buyer on this island to treat the County's protection zones as a design brief rather than a hurdle. The homes that age best are the ones that honor what grew here first.

FAQ
Are live oak trees protected in Florida?
There is no blanket statewide ban on removing live oaks. Protection comes mostly from local ordinances, and Florida law limits them for qualifying single-family homes with a documented unacceptable-risk tree. On unincorporated Amelia Island, Nassau County protects healthy trees of 5 inches DBH or more and applies extra review to specimen live oaks.
Can I remove a live oak just because I don't like it?
No. Nassau County approves removal only for just cause, such as a hazardous tree or new development, and says aesthetic concerns are not a valid reason. If you believe the tree is a danger, get a risk assessment from an ISA-certified arborist before you apply.
Does pruning a protected live oak need a permit?
Generally no. The County says pruning and minor maintenance usually do not require a permit, but they must follow ISA and ANSI A300 standards. Heavy cuts or canopy removal go beyond minor maintenance, so ask the County Arborist if you are unsure.
How far from the trunk should construction stay?
The County's protection zone is six times the trunk's DBH, with a minimum of 6 feet. A 20-inch oak gets a 15-foot zone, for example. Buildings, paving, digging, storage and parked vehicles stay outside it.
