At what point does a building become under the new portion of the code. in Health care if you remodel an entire compartment on say 3rd floor and you have 6 more floors above are the shafts and stairs having to be brought up to new code standards?
Will pull up 101 later, but should say in the "Scope" of each chapter
Ok read you question again,
1.Normally you bring what you touch up to code
2. You cannot make exiting and some other stuff worse. My take is you would not have to touch anything above
The information is in Chapter 43 of the 2012 Edition of the Life Safety Code.
