  • Main rule I'm aware of (does not mean there are not others I'm not aware of) has to do will sill height above the floor.

As Ecnerwal noted, IRC code of 2018 required "glass within 24" of ANY doorway to have tempered glass if the glass within the 24" distance was LESS THAN 60" off the floor level".
