Marriott Mid-Rise vs. Code High-Rise

Summary: Comparison of a Marriott mid-rise smoke control and building construction requirements compared to a Marriott under full IBC code high-rise smoke control and building construction requirements.

Marriott construction guidelines define a mid-rise hotel as any hotel more than six stories and less than 75 feet tall.  For this mid-rise classification, Marriott requires certain aspects of a high-rise building to be included in the design.  The following is a comparison of the these requirements relative to what is required by the IBC for a fully  classified high rise hotel.

As is often the case, when a local jurisdiction is informed that a mid-rise hotel is going to be designed per the Marriott criteria, full high-rise criteria is imposed.  Check with your local jurisdiction regarding this issue at the start of your project to avoid surprises.
