For residential lots, only trees 16 inches in diameter (measuring trunk 4 1/2 feet from the ground) require a permit from the Town of Mount Pleasant. Residential trees that are exempt from a permit, but per § 156.225 still require a tree protection zone on site plans, are those under 16 inches in diameter as well as the following tree species: pine, sweet gum, callary pear, river birch, mimosa, chinaberry, Chinese tallow, camphor tree, and white poplar trees. Trees located within special buffer areas, critical areas, easements, or rights-of-way may be protected regardless of size or species.
Yes. The Town allows accessory dwelling units (ADUs) in most residential zoning districts. Please call the Planning & Engineering Division at (843) 884-1229 to verify that there are no restrictions on your property and an ADU can be constructed on your property. Size, location, occupancy, and other requirements may be found in Zoning Code Section 156.110 & 156.111. A building permit application must be submitted to the Building Inspection Division. The application will be reviewed and approved by both the Building Inspections and Planning and Engineering Divisions before a permit is issued.
