Egress Window Requirements South Carolina: What You Need to Know

When homeowners start a project around egress window requirements South Carolina, they usually want one thing first, a clear answer on whether the opening will pass code. That question matters most in bedrooms, basements, and any room used for sleeping.

Window style can make the difference between a near miss and an approved opening. Single-hung units sometimes work, but the operable space has to be measured carefully. Double-hung windows are often easier to fit to egress because the design may provide a larger usable opening.
