Thanks Richard,

The issue I am having trouble with is the exceptions to the requirements (In IRC 2006) which are as follows:

"9. Safety glazing in Section R308.4 , Items 10 and 11, is not required
where:

9.1. The side of a stairway, landing or ramp has a guardrail or handrail,
including balusters or in-fill panels, complying with the provisions of
Sections 1013 and 1607.7 of the International Building Code ; and

9.2. The plane of the glass is more than 18 inches (457 mm) from the
railing; or

9.3. When a solid wall or panel extends from the plane of the adjacent
walking surface to 34 inches (863 mm) to 36 inches (914 mm) above the
floor and the construction at the top of that wall or panel is capable of
withstanding the same horizontal load as the protective bar."

I do not think any of the exceptions apply to the window in the first photo, but exception 9.3 may apply to the window facing the stair head (right side window) in the second photo, as the wall from the stair step to the bottom of the window sill appears to be 34 inches or greater.

The left hand windows in the second photo do not appear to meet the requirements of the exceptions.

Thanks,

Eric
