If you are just updating your basemnt you still need to bring it up to the curent code. Egress window requirement codes state when grade conditions require the sill of the egress windows to be below the outside grade elevation, then a window well must be constructed.
The required horizontal area of a window well is a minimum of 9 square feet which is measured when the window is in the open.

We recommend a casement window to get the position and size of window needed to comply with the current egress window code. If you are remodeling your basement you will need to have an egress window or door installed. Installing an egress window or egress door walk up is no easy project, it reqires a class A contractor in the State of VA with a BLD stamp.
