I have a question about building height and area.
In the code, according to 506.4, when we calculate the allowable area, for two level building we multiple area by 2 and for building more than 2 levels, we multiple area by 3(no matter how many floors it has?).
Then I notice 504.2, if it has sprinkler system, the allowable floor level will be increased by 1.
I would like to know if there is a building which allows 3 levels in 503 form and it has sprinkler. So when I calculate the allowable area should I multiple 3 or 4?
