How the South Carolina estimate is adjusted
- Labor
- We apply the South Carolina labor multiplier only to labor-heavy line items, so material prices do not rise or fall just because local wages differ.
- Climate
- The local climate note is included because weather exposure, humidity, freeze-thaw cycles, or coastal conditions can change product choice and prep work.
- Taxes and permits
- The estimate applies the market tax model and flags whether local permit costs are usually part of the homeowner budget.
