Richland County's single-family districts control building bulk mainly through setbacks and the 45-foot height cap rather than a fixed lot-coverage percentage. Accessory structures in residential districts may not exceed 50% of the principal building's floor area (or 1,200 sq ft) and may cover no more than 30% of the yard.
The Richland County Land Development Code (Chapter 26) shapes buildable area in single-family districts primarily through setbacks, minimum lot size, and the 45-foot height limit rather than a single site-wide impervious-coverage percentage; some overlay and neighborhood districts (for example, the Crane Creek CC district) do set a maximum impervious surface ratio of 40%. For accessory structures, the code is explicit: in residential districts they may not exceed 50% of the gross floor area of the principal building or 1,200 square feet (whichever is greater) and may cover no more than 30% of the yard. Larger caps apply in the RU rural district for lots of two acres or more. Verify your district's exact standards before adding buildings.
Accessory buildings or lot coverage exceeding the limits require a variance; non-compliant structures can face removal orders and civil penalties.
