Hi Michele,
There is, in most locations, some type of "grandfathering in" of existing structures - with conditions. One of those conditions typical is that the structure is a legal structure (i.e., was constructed to the code applicable at the time of construction and met local zoning, etc., requirements applicable at the time of construction) and another is that the use and occupancy of the structure does not change.
This is from the 2006 International Existing Building Code and addresses the above with a twist (see bold text): (bold and underlining are mine)
- 101.4.2 Buildings previously occupied. The legal occupancy of any building existing on the date of adoption of this code shall be permitted to continue without change, except as is specifically covered in this code, the International Fire Code, or the International Property Maintenance Code, or as is deemed necessary by the code official for the general safety and welfare of the occupants and the public.
From your description, the use and occupancy has not changed, however, and also from your description, I'm not sure your house was a legal structure at the time of construction. No code that I am aware of allows/allowed for a ceiling height as low as you describe yours to be.
That indicates that, somewhere along the time line of the structure's life, changes were made and the upper floor was converted from attic to living space.
You may likely need to go to the building department and see if they have the plans and permit information for your house, they may not have it in paper, but may have it digitally or on micro-fiche. IF they do have the construction permit information, you may find that the building was not constructed as you bought it, and thus it would not be grandfathered in.
However, IF the building was constructed as it is now, you have a good chance of presenting that information from the building department and having its status changed to 'non-conforming legal structure', which means it would most likely be able to remain as it is until something big happens and the cost of repairs, alternations, etc., equals greater than 50% percent of the value of the structure, in which case the local building department may well call for the entire structure to meet current codes.
Note that the Pennsylvania Uniform Construction Code, in Part XIV, included the 2006 International Existing Building Code.
