Please see the attached memorandum regarding mixed-use structures within the city of Philadelphia. The City of Philadelphia adopted the 2018 ICC codes and this created an issue when constructing units with other than Group R sections being placed within or on top of the structure while being constructed to different code versions. They had several discussions with the City of Philadelphia and came to a conclusion when constructing this type of structure. Please see the attached memorandum which explains how these types of mixed-use structures will be handle for the City of Philadelphia.
They believe this is the most appropriate method which preserves the exemption under the Pennsylvania Uniform Construction Code.
This does not affect structures if no other use group sections are being placed within or on top of the structure; in that case the 2015 codes remain in effect and remain exempt.
