City of Charleston has protected and grand-tree rules

The City of Charleston defines protected and grand trees and publishes separate removal requirements based on property type, tree diameter and location. Some single-family residential removals are exempt below certain thresholds, while larger trees, buffers and other property types can trigger additional rules.

Mount Pleasant has its own thresholds

The Town of Mount Pleasant says certain residential trees 16 inches DBH or greater are protected, with separate rules for pine trees and historic trees. The Town requires approval before protected-tree removal and uses its OPAL permitting system.

Charleston County also regulates protected and grand trees

Unincorporated Charleston County has its own tree-removal packet and definitions. County rules should not be assumed to match the City of Charleston or Mount Pleasant.

Stump grinding does not erase the permitting history

If a tree is still standing or has only recently been removed, confirm that any required approvals were handled before treating the project as “just a stump.” A stump contractor should not be used to bypass tree-protection rules.

What property owners should verify

  • Which municipality or county has jurisdiction
  • Whether the tree was protected by size, species or location
  • Whether the property is in a buffer, easement or right-of-way
  • Whether removal was associated with construction
  • Whether mitigation or replacement-tree requirements apply

Frequently Asked Questions

Do I need a permit just to grind an existing stump?

Permit rules are usually tied to tree protection and removal, but requirements vary by jurisdiction and site. If there is any question about how the tree was removed or whether the stump is in a protected area or right-of-way, confirm with the local authority.

Are Charleston and Mount Pleasant rules the same?

No. They publish different thresholds and procedures.

What if the tree was in a public right-of-way?

Public trees and right-of-way work can have separate rules. Confirm responsibility with the applicable local government before authorizing work.
