Basement Egress Window Requirements in Washington DC: A Complete Overview

What The Code Means By A Basement Egress Window
A basement egress window is not just a bigger window. It is an emergency escape and rescue opening that has to be large enough for a person to get through without turning a finished lower level into a dead end.
