In South Carolina, the regulatory framework for ADUs is largely determined by local municipal ordinances, which vary in their specific requirements regarding size, setbacks, and parking, though many cities are increasingly supportive of ADU development. All construction must adhere to the South Carolina Building Codes, which encompass state-mandated standards for structural performance, fire safety, and energy efficiency. The existing housing stock in cities like North Charleston, which often comprises a mix of older homes and newer constructions, means that ADU integration requires careful design to ensure compatibility with existing infrastructure and neighborhood aesthetics, while also meeting modern building performance expectations.
