How to Measure the Height of an Emergency Escape and Rescue Opening

[Sifu]

I open the window, run the tape from finished floor, bend down and eyeball the highest point.

This is code creep. If the bottom of the glass is enforced than 99% of existing EEROs will be non-conforming.

Can I change my handle to "Code Creep!"

The 2018 IRC requires the window sill height to be not more than 44". Usually, the window sill is lower than the window opening.

Correct however the 2018 IBC stated
1030.3 Maximum height from floor.
Emergency escape and rescue openings shall have the bottom of the clear opening not greater than 44 inches (1118 mm) measured from the floor.
so the 2021 IRC was changed to match the IBC requirement

So windows do not have a window sill per se just window trim

The sill is visible from the outside. The inside is the stool.
