Building Code Policy
Lapeyre Stair's continually expanding product line incorporates flexibility and interchangeability of components into the engineering design to meet the access requirements of various laws, standards, and building codes applicable both locally and globally.
By offering products that can be selectively configured, Lapeyre is able to provide costeffective design alternatives capable of meeting most United States and International laws, standards, and building codes as described in their current or most recently issued editions.
Lapeyre can offer no guarantees that a particular stair configuration will be accepted by local authorities. However, detailed drawings of access devices are available in order to provide an opportunity for compliance approval prior to purchase. Local architects, building code officials, and codes are each reliable sources of compliance specifications/recommendations.
All capacity ratings for Lapeyre Stair conventional tread stairs are stated in terms of the live load capacity of the stair system with a given safety factor. Local wind, snow, and seismic rating requirements are not included in this capacity rating. Local requirements for these loadings, where applicable, must be considered by local architectural or engineering professionals.
Code Compliant Stair Designs
Lapeyre's computerized system designs stairs based on the building codes provided by clients. Because individual municipalities may modify or tighten the requirements of the major codes, it is always recommended that local code officials review the dimensional prints provided by Lapeyre.
Visit individual code compliance pages to determine which Lapeyre stairs best fit different building codes.
