Staircases in Modular Homes
I've seen modular houses in my development. Naturally, they have joists for flooring as well as ceiling on each module.
There are four modules in a typical house (front/back/upper and lower floors).
But what happens with staircases? Don't they have to be longer to span the added (10 inches or more) height due to the fact that, unlike a stick built (where the ceiling joists of lower floor also serve as the floor joists of upper floor) a modular has "two sets" of joists between floors? And if so, is there ever a code problem with the increase of number of steps? I'm just curious.
