How Narrow Can a Staircase Be for a Stair Lift?

Narrow staircases are a common concern for homeowners wanting to install stair lifts. But most staircases can handle stair lifts, and those as narrow as 28 to 30 inches wide have enough room to support the mobility device. 

Here’s what you need to know about narrow staircases before buying a stair lift. 

What’s the Minimum Width for Stair Lifts?

Most stair lifts can be installed on staircases as narrow as 28 to 30 inches wide. That covers the majority of homes in the Kansas City area, including older properties where staircase widths tend to be on the smaller side.

To measure your staircase, measure from wall to wall (or wall to banister) at the narrowest point. If you’re at or above 28 inches, a stair lift will very likely work for your home.

What Happens When I’m Not Using the Seat?

Stair lift seats look bulky and as if they’d eat up walking space on your staircase, but the good news is they’re designed to be as out of the way as possible. 

The seat, armrests, and footrest all fold up when not in use, which frees up clearance so others can walk past without issue. It will likely still stick out into the staircase, but doesn’t take up the entire walking path when not in use.

If there are other people in the house, you’ll have to remember to put up the seat so they can use stairs freely. 

What About Curved or L-Shaped Staircases?

Width is just one factor. Some Kansas City homes, especially older builds, have curved, L-shaped, or split-level staircases. 

These staircases require a custom-manufactured rail rather than a standard straight track. The process takes longer and costs more, but width requirements are similar and seats can be folded up when not in use.
