Terminology of Vertical/ Horizontal exit enclosure; through a firewall

[cda]

A fire wall is not required to create separate fire areasThe code does not use the term "assumed property line"

Is there some reason you are trying to create 2 buildings?

Why are you assuming a property line running through the building?

"""The stair is required for the top side building. the PL- should read APL-Assumed property line, as that wall is a firewall through the building to split the building into allowable fire areas."""

You can break up a building into multiple fire areas using fire barriers and or fire walls and never assume a property line

MT.....I assume they mean to get around H&A with separate buildings.....but then again, maybe they only need a fire barrier.....
