What are the requirements for a mobile/manufactured home stairs?
Saturday, May 8, 2021
HUD requires stairs at each exit door from a mobile home, including sliding glass doors. But the construction details of the stairs fall under the jurisdiction of the local building department. Each local code is slightly different, but here are some of the generally accepted standards for manufactured/mobile home stairs, per the International Residential Code (IRC):
- Minimum three feet wide. If door is wider, the landing must be at least the width of door.
- Landing at top of stairs minimum three feet deep.
- There should be a railing on both sides of the stairs that is a minimum of 34” high, with pickets not more than 4” apart—a spacing that does not allow a small child’s head to get stuck between them.
- There must be a handgrip on at least one side of the stairs. The handgrip must be small enough to easily wrap your hand around. If it is separate from the railing, then the ends must return back to the railing cap, wall, or end post so that it is not possible to snag a handbag or sleeve on the end and tumble down. Handgrips must be between 34” and 38” above the nosing (front edge) of the treads.
- Risers should not exceed seven and a half inches high, with not more than a quarter inch variation in height between risers. The first and last risers are where we typically see any change in riser height.
Also, the stair structure should be freestanding and not bear on the mobile home or otherwise use it for support in any way. For more details, go to our blog post Do I need stairs at all exit doors from a mobile home?
