I have a building that was built in 2004 under the 1996 BOCA. It was designed as a type VB as an S-1 with sprinkler increase and being used as B doctors offices.
So under BOCA 96 it was a single story (story increase to 2 for sprinklers) of 4,200 sq. ft. with 200% increase as S-1 for a total of 12,600 sq. ft. And built at around 12,400 sq. ft. single story. That was their max at the time.
Today, if someone was to design this same building under the 2006 IBC an S-1 is allowed 9,000 sq. ft. with the sprinkler increase of 200% for a max. area of 27,000 and 2 stories for the increase.
Does this sound correct? Could someone now add 14,600 sq. ft. more to this same building? Could they also redesign it for a 2nd floor or 3rd floor under B use which would give the same square foot of 27,000?
Nobody is suggesting this but a plan came in for remodel on this site and I got to wondering. Especially when they didn't do their homework and wanted to call it a IIIB, B use and all of a sudden this building would be allowed to be 95,000 sq. ft and 5 stories tall. Again, nobody suggesting to add any floor or sq. ft.
