According to the IBC, what is the maximum height increase allowed for a fully sprinklered building compared to the tabular allowance for its construction type?

Answer: 15 feet

The IBC allows a building height increase of 20 feet when the building is equipped with an NFPA 13 automatic sprinkler system throughout.
