Egress Window Requirements Under South Carolina Building Code

Egress requirements come up fast when homeowners start finishing a room, turning a den into a bedroom, or swapping out an old window that never quite felt right in the first place.

At the jobsite level, egress is not a technicality. It decides whether a window opening is safe, legal, and acceptable for a finished room.

That means the exact permit process can vary a bit from one city or county to another, but the core egress measurements are usually consistent.

Where Egress Windows Are Required

If a space is used as a bedroom, the window serving that room usually has to meet egress rules unless the room has another compliant exit.

Most homeowners run into egress requirements during basement remodeling, attic conversions, or when they divide one large room into multiple bedrooms.

Permits, Inspections, And Common Mistakes
