Re: recept in a hospice
The 2005 NEC has changed the definition of Dwelling unit to match the definition in the IBC.
This change makes it more clear IMHO.
I think it would depend on the occupancy classification it would fall under. If there are more than 16 people than it could be classified a I1, which is an Institutional occupancy.
I wouldn't require AFCI in this case.
