How Tall Should Windows Be for Egress in South Carolina Code

For egress, the important measurement is the opening after the sash is fully open. A window can look large enough from the room and still fail code if the clear opening is too small.

Most South Carolina jurisdictions use that baseline, though local adoption and inspection practices can vary, so the exact answer for a permit should always be checked against the current building department requirements.

I have seen plenty of jobs where the rough opening looked fine, but the finished window could not meet egress because the clear opening was pinched by the operating sash.

For bedroom egress, the usual code checks go beyond height. The window also needs to Sumter Window Replacement be easy to open from the inside without keys, tools, or special knowledge, and the sill height typically cannot be more than 44 inches above the finished floor.

If you are planning a replacement project, the window type matters more than many people expect. Casement windows often make egress compliance easier because they can provide a large open area relative to the frame size.

• Does the opening meet the 24-inch minimum clear height?
• Does it provide at least 5.7 square feet of clear opening?
• Is the clear opening width at least 20 inches?
• Is the sill no more than 44 inches above the floor?
• Can the window be opened from inside without special tools?
