Egress Windows

[mcyr (Marcel Cyr, CMI)]

Marcel, the min clear width is 20". The clear area is 5 sq ft on the ground floor, and 5.7 sq ft on the upper floors. A lot of people miss that one.

In Larson’s graphic, the 46" dimension is to the “clear area” accounting for the bottom of the window frame. The “means of escape” height to the interior sill is 44", not the clear area from what I understand. I have had the AHJ in my area sign off on smaller egress windows that are double hung tilt-outs. By removing both sashes, it meets the egress rule as long as the sill is at or below 44" and the clear width is 20" or more, the min clear height is 24", and the min clear area is at least 5 sq ft on the ground floor.

Sorry, that was a typo, 20" it is.

Sorry for the thread drift but nothing more can be added on Egress.

Bob, I don’t see any Wisconsin cities on this list but I notice your little berg is.:shock:

3rd largest city but #24 is doing pretty good.

Here we can jump higher so 48 inches it is.

That would be the 5.7 sq. ft. Larry. They are looking for a minimum height of 24" and a minimum width of 22". Whatever the combination, it has to equal 5.7 sq. ft…

The sill height is maximum of 44", unless local codes change it to less.

Same as here Marcel.
