In this Section it has a Specific Text regarding Group R and it goes thru the explanation of allowable increase of 20' and an increase of one story for a fully sprinklered building, but it adds ""but shall not exceed 60' or four stories respectively."" In Table 503 most of the Group R is already at 4 stories and above 60'. I need this clarified as it seems to contradict all the previous information. Thank You.

Is it the intent of this section to allow a 20 foot increase in building height but not be able to add the additional story in Group R buildings?
View
Is it the intent of Section 504.2, Exception 3, to allow a 1 hour fire rating of the building structure in lieu of sprinklers for a 4 story Single Family Dwelling?

Input Received:

Concerning the FBC - yes it is increased
to a maximum of four stories with a NFPA
13 sprinkler system, NOT 13R.

Discussion of the differences between the
Codes should be on the message boards.

Agree with Michael, NFPA 13 system.

Yes, for an R-2 with Type VA
construction, Table 503 limits you to 3
stories. With either a 13R or a full 13
system, you can go to four stories.

The differnce would be if you were
dealing wiht a 4 story limit in Table
503, like for a Type IV building. Then
you could only go four stories with 13R
but you could go 5 stories with a full
13 system.
