Planning to add a room, a pool, or a new home where a live oak casts that beautiful Lowcountry shade? You’re wise to pause. James Island’s tree rules are strict, and a 2024 change lowered the threshold for “grand trees,” which affects many lots. In this guide, you’ll learn how the rules work, what permits you need, and the steps to keep your project on track. Let’s dive in.
Confirm your jurisdiction first
James Island parcels sit in one of three jurisdictions: the Town of James Island, the City of Charleston, or unincorporated Charleston County. Each has different tree rules and permit processes. Before you plan anything, verify which one governs your address through local tools or by contacting the Town’s Planning & Zoning team. You can start with the Town’s planning page for guidance and contacts.

Know the 2024 Town standard
If your property is inside Town limits, the Town’s updated code defines a “grand tree” as any species with a diameter at breast height (DBH) of 18 inches or more, except pine and sweetgum. Protected trees are generally any tree 8 inches DBH or larger before development. DBH is measured 4.5 feet above the ground. These standards guide what you can remove, how you design around trees, and what approvals you need.

What counts as protected
- Grand trees: DBH 18 inches or more, excluding pine and sweetgum.
- Protected trees: DBH 8 inches or more on most lots and all trees within required buffers and landscape areas.
Why it matters
Grand trees cannot be removed without a permit. Even trimming and construction near these trees is regulated. Violations can lead to fines and required replacement planting or payments into the Town’s Tree Fund.
Permits and plans before you build
You need the right paperwork in place before any site work begins. The Town requires a zoning permit for development, and a tree plan is part of that review. A preconstruction planning conference focused on tree preservation is required before permits are issued.

Tree survey requirements
A licensed surveyor, landscape architect, or civil engineer must prepare and seal a tree survey and plan. Show the location, size, and species of protected and grand trees, canopy drip lines, and distances to proposed construction. Grand trees within key distances of your project must appear on the plans.

On-site protection near live oaks
Once work begins, the Town requires sturdy protective barricades. Place them at the canopy drip line or at a radius equal to 1.5 feet times the DBH in inches, whichever the Town approves. Keep the protected area free of fill, materials, vehicles, and heavy equipment unless the Town signs off on special methods.
Excessive pruning is also restricted. Removing more than 25 percent of the leaf surface in one growing season, or taking more than three limbs 6 inches in diameter or larger without approval, is considered damage.

When removal is allowed
Removal may be approved if a tree is dead, diseased, or poses a safety hazard that cannot be remediated. If the Town denies removal, you can seek relief through the Board of Zoning Appeals in hardship cases. Emergency removals are allowed with documentation and a post-removal review.
If removal or damage occurs, be ready for mitigation. The Town may require planting replacement canopy trees, typically at least 2 inches caliper, or payment into the Tree Fund when on-site planting is not practical.

City and County differences on James Island
If your lot sits inside the City of Charleston, the City often treats grand trees as 24 inches DBH or larger, excluding pine and sweetgum. The City uses a protective zone formula that starts at 12 feet for a 24-inch tree, with additional distance for larger trees. The County also uses similar thresholds in its ZLDR but has different exemptions and procedures.

Step-by-step: build responsibly under live oaks
Confirm jurisdiction. Identify whether your parcel is in the Town, City, or County before you plan or trim.
Order a sealed tree survey and plan. Include DBH, species, drip lines, and distances to improvements.
Schedule the preconstruction conference. Work with the Town’s Zoning Administrator to confirm barricades and approved methods.
Install and maintain barricades. Keep protected areas free of storage, traffic, and fill unless specifically allowed.
Apply for removal only if needed. Never cut a grand or protected tree without a permit. If denied, consider the appeals path.
Plan for mitigation if removal happens. Replacement trees or Tree Fund payments may be required.
Bring in an ISA-certified arborist. Use professional reports for hazard claims and root-friendly construction methods like air spade excavation or pier foundations when the Town approves.

Pro tips for designing around live oaks
- Shift footprints and utilities to avoid root zones and canopy drip lines.
- Use lighter-touch construction techniques, such as pier or grade-beam foundations and hand or air spade excavation in sensitive areas.
- Stage materials outside protection zones and plan access routes early to prevent compaction.
- Prune only with approval and under professional guidance to maintain canopy health.
Building near a live oak can be done well with the right plan. You protect a defining part of James Island’s character and reduce delays, surprises, and costs.

FAQs
Can I remove a live oak on my James Island property?
- It depends on jurisdiction and size. In the Town, live oaks at 18 inches DBH or more are grand trees and require a permit, and protected trees at 8 inches DBH also face limits. See the Town’s rules for details.
How do I measure tree DBH for permit purposes?
- Measure diameter at breast height, which is 4.5 feet above the ground. For multi-trunk trees, follow the code’s measurement rules or hire a professional.
How close can I build to a live oak in the Town?
- The Town requires barricades at the drip line or a radius equal to 1.5 feet times the DBH in inches, and special construction methods may be required inside that area.
What happens if a grand tree is cut without permission?
- The Town can assess fines and require mitigation, including replanting canopy trees or paying into the Tree Fund based on replacement costs.
Who handles permits if I hire a builder on James Island?
- Your contractor may manage permits, but you remain responsible. Ensure contracts require compliance with Town, City, or County tree rules and include the preconstruction conference and protection plan.
