8 rules for unincorporated Dorchester County, South Carolina.
Verified from official government sources
Dorchester County sets no fixed inch limit; overgrown grass, weeds, and undergrowth are abated as nuisances under its environment code. The SC Right to Farm Act shields working farms, and Summerville enforces its own overgrowth limits in town.
S.C. Code Ann. § 46-45-70, South Carolina Right to Farm Act
No established agricultural facility or any agricultural operation at an established agricultural facility is or may become a nuisance, private or public, by any changed conditions in or about the locality of the facility or operation.
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.
Dorchester County Zoning and Land Development Standards (Ord. No. 04-13), § 12.4.3(c) Tree and Canopy Protection Standards
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.
Dorchester County requires a Tree Removal Permit to destroy a Protected tree. Grand trees (24-inch DBH, including pine) and Significant trees (15 to 24 inch, excluding pine) are protected; small single-family lots are exempt except for non-pine Grand trees.
Dorchester County Zoning and Land Development Standards (Ord. No. 04-13), § 12.4.4 Tree and Canopy Protection Standards
Except for parties specifically exempt, it shall be unlawful to fell, improperly prune, or otherwise destroy a Protected Tree without first obtaining a Tree Removal Permit from the Zoning Administrator.
Dorchester County abates weeds and rank undergrowth as nuisances under its Chapter 14 environment code, working from complaints rather than a set height. The county can clear a neglected lot and lien the cost; Summerville enforces its own overgrowth rules in town.
Dorchester County has no everyday watering calendar, but under the SC Drought Response Act water providers like Summerville CPW and Dorchester County Water and Sewer must impose staged limits when SC DNR declares a drought, cutting or banning nonessential outdoor watering.
S.C. Code Ann. § 49-23-90(A), South Carolina Drought Response Act
Municipalities, counties, public service districts, special purpose districts, and commissions of public works engaged in the business or activity of supplying water for any purpose shall develop and implement drought response ordinances or plans where authority to enact ordinances does not exist.
Rainwater harvesting is legal and effectively unregulated in Dorchester County. South Carolina places no restriction on collecting rooftop rain, and rain barrels and cisterns for lawn and garden use need no county permit.
No South Carolina statute or Dorchester County ordinance restricts native or drought-tolerant landscaping. You may plant Lowcountry natives, live oaks, and pollinator beds freely; HOA covenants are the main constraint on replacing a grass lawn.
No South Carolina statute or Dorchester County ordinance governs artificial turf. Homeowners may install synthetic lawns without a county permit; HOA covenants are the main limit, and large installations near wetlands may face drainage review.
