Alternating Tread Stairs in Residential Applications

The product that we sell can not be sold for the residential market. Below you will find answers to many frequently asked questions about the Lapeyre Stair and the residential market.

It does not meet building codes

You may see references to alternating tread stairs in your local building codes. But our steel and aluminum models do not meet these codes. We used to manufacture a wooden stair that we designed to different specifications.

It is designed for use by able-bodied adults

It is not possible to turn around on our stair. Nor can two feet be placed on the same level at the same time. It is difficult for children and the elderly to use our stair. In addition, the handrails do not meet the baluster (vertical rail) requirements for residential stairs. Children could easily fall through the rails to the ground below.

What if I do not have children and would like to use the stair anyway?

Although the home in question may not have children now, there can be no guarantee that in the future, children will not live in, or visit a home. Future owners may have children. This does not change the fact that we can not sell the stair for use in a home.

What happened to the wooden residential stair that Lapeyre Stair used to sell?

Due to business needs and an increase in our industrial ladder business, we discontinued the wood stair in 1990.

I have the perfect application for the alternating tread stair in my home, what can I do?

There is a company that manufactures a wood alternating tread stair that is designed for residential use. The company is Arke Stairs, the Karina model. You may visit their website at
