The builder of a home I designed in Texas posed an interesting question: what exactly constitutes a "landing", for an exterior (non-egress) door to a back yard? 202 offers no definition. 311.3 says "There shall be a landing or floor on each side...". In lieu of concrete flatwork or buying a paver, he wants to know if he can simply raise grade to within 7 3/4" of the threshold, slope away at 1/4":12" or less, cover it with decorative gravel, and call that "landing". I'm inclined to say yes. Without a clear definition, it seems to me IRC is just looking for a solid surface to catch walking feet, not too far below. Anyone have direct experience with officials/inspectors on this point?
