    I have a sill height of 44" but code says clear opening is where the measurement is taken. With the bottom rail the clear opening is 46". Would a 12" deep by 4" tall step for the full width of the window be acceptable. I would have it solidly affixed to the floor and wall. I realize anything can be removed at any time in the future but on inspection it would meet the intent of the code.

    Put a step below it on the interior.

    Our code states the 44" is "measured from the "floor". We would not accept a step. However, we have accepted raised floor areas (ie., landings) that are as wide as the window opening, and at least 36" deep

    If you have the 5.7 sf. and 20" W by 24" H clear opening you still meet the minimum. The grade floor openings have the exc. to only have 5.0 sf of opening.

    This is our interpretation as well. A step does not constitute a floor area.

    Huh?

    R310.2.2 Window Sill Height
    Where a window is provided as the emergency escape and rescue opening, it shall have a sill height of not more than 44 inches (1118 mm) above the floor; where the sill height is below grade, it shall be provided with a window well in accordance with Section R310.2.3.
