- Protected even on home lots
- Boundary branches
- Trim to property line
- Summerville
- Stricter town ordinance
Summary
You may prune your own trees in Dorchester County, but the county tree ordinance still protects non-pine Grand trees even on small home lots. Overhanging branches may be trimmed to the property line; Summerville and HOA rules add stricter limits in town.
Nothing in this Section shall be construed to prevent the ordinary pruning, trimming and maintenance of a tree, nor shall anything in this Section be construed to prevent the cutting or removal of any tree that the authorized County offices deem required for public safety.
Full Breakdown
Dorchester County's Tree and Canopy Protection Standards protect trees, but the ordinance expressly allows ordinary pruning, trimming, and maintenance, so routine care of your own trees needs no county sign-off. The catch is the Grand tree: an occupied single-family lot of one acre or less is exempt from protecting Significant and pine trees, but not non-pine Grand trees 24 inches DBH or larger, so improperly destroying a big live oak still breaks the code. Inside Summerville, the town's own tree ordinance is stricter, and the common-law rule lets you trim a neighbor's overhanging branches only back to the property line.
Violations & Fines
None for ordinary pruning. Improperly pruning or destroying a Protected or Grand tree without a permit violates the county tree ordinance, and crossing the boundary to harm a neighbor's tree invites civil liability.
