For fire flow modification I would need to submit the building under the IBC instead of the IRC.It is a townhouse, under the IRC, period. There is no classification.
If one were to build it under the the IBC, then yes, I would call it an R-3.
Exception: Detached one- and two-family dwellings and
townhouses not more than three stories above grade plane
in height with a separate means of egress, and their accessory
structures not more than three stories above grade
plane in height, shall comply with this code or the International
Residential Code.
We are proposing groups of 5 townhouses for this development.It's not a townhouse if it is not connected to other townhouses.
Yes, this definition is what makes me question weather or not a townhouse could be, or would be, considered R-2It's not a townhouse if it is not connected to other townhouses.
It would have to be NFPA13 under the IBC instead of NFPA13D under the IRC? That seems like a big deal.would the sprinkler system be different IBC vs. IRC?
But if constructed under the IBC it would have to be NFPA13, correct?IRC, you can install a P2904 combination system, off the domestic supply, fraction of the cost of a NFPA 13R.
no, I see I'm wrong. It would be NFPA 13RBut if constructed under the IBC it would have to be NFPA13, correct?
