Summary
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.
Accessory structures in residential districts shall not exceed a maximum total area of fifty percent (50%) of the gross floor area of the principal building or one thousand two hundred (1,200) square feet, whichever is greater, and shall not cover more than thirty percent (30%) of the yard.

Full Breakdown
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.
Violations & Fines
Accessory buildings or lot coverage exceeding the limits require a variance; non-compliant structures can face removal orders and civil penalties.
