Commercial Stairs Rendering

IBC Commercial Compliance

IBC requirements apply to stairs accessible by the general public and include stairs that are used as a means of egress from a building. These standards are focused on the safety of all people, including children and the eldery. 

The design of IBC stairs is determined by the type of building where they will be used and its occupancy. Our stairs that comply with IBC commercial egress standards are also ADA compliant. Most jurisdictions in the United States have adopted IBC standards as their base code. Check with your local code enforcement to ensure the stair designs for your project are compliant prior to issuing approval to us for production.
