Now when it's a midrise or highrise building that's a fair piece of change.
I'm not sure how many stories are required for a building to be considered a high rise, but under the IBC the tallest building that can be built using type III, IV, or V construction would be 5 stories. With a sprinkler system, that would increase to 6 stories. That is for an office building. With merchantile or residential occupancies, the limit would be 4 stories with a sprinkler increase to 5 stories. Those figures are for type III and IV. The limits for type V are less. Any buildings taller than these limits would need to be type I construction, which would prohibit the use of NM cable.
Other building codes will have story limits for type III, IV, and V construction in the same ball park.
