that would be 1-hour FRR if building separation were 3 ft(half of 6 ft)
between U occupancies.
reference:
2006 IBC Table 602.
Special mention at Section 406.1.2 and 406.1.3 for garages,
but only as analogy.
1-hour FRR on each facing side might be enough to validate not
adding sprinklers. of course, if there is not 1-hr FRR at this time
getting to that may be more cost than adding the sprinklers.
