What is an egress window and when is it required?
An egress window is an operable window, which provides a means for emergency escape or rescue in residential occupancies. Basements in dwelling units and each sleeping room below the fourth story needs to have at least one (1) operable window or door which meets the requirements for emergency escape or rescue, and opens directly to the exterior of the building. For more information and size requirements, see brochureBP-59 Basic Requirements for Emergency Escape and Rescue Windows.
