Does NCRC allow additions to buildings over the allowable area permitted for new construction, without fire separation?
The Rehab Code allows an increase of 25% in allowable area, for 1 & 2 story buildings only, before separation is required. This recognizes that the building code allowable area tables have historically been all over the map, rarely being based on hard loss of life data; more often these tables are the best guess of what is safe, at any given time, and the source of many differing opinions among code officials.
