Spartanburg County's ULMO does not set a residential retaining-wall height limit, but a wall over 4 feet (or supporting a surcharge) typically needs a building permit and engineering. In the City of Spartanburg, retaining walls over 6 feet require architectural treatment to break up the mass.
The county building code follows the International Residential Code, under which retaining walls generally need a permit and engineered design once they exceed 4 feet in exposed height or retain a slope/surcharge. The City of Spartanburg's landscape and buffer standards require that 'architectural treatment of proposed retaining walls over six (6) feet in height' be provided, using durable materials such as precast block or brick plus terracing, so tall walls do not read as a single mass. Confirm drainage and easement impacts before construction.
An unpermitted or failing wall can draw a stop-work order and must be certified by an engineer or rebuilt.
