One building, 2-Family Dwelling vs. 1-Family Dwelling W/ an Attached Accessory Structure.


All,

I am currently reviewing a set of construction documents for a building that appears to be a 2-Family Dwelling (my opinion), but I'm getting conflicting views from people I really trust on whether the building is actually a 2-Family Dwelling or a 1-Family Dwelling with an attached "accessory structure".


The building in question is elevated for flood roughly 10' above grade, two-story total. The building contains two dwelling unit(s)* (for arguments sake) that are separated by a shared breezeway, but share/connect the same roof and floor structure (one building).


"*DWELLING UNIT. A single unit providing complete independent living facilities for one or more persons, including permanent provisions for living, sleeping, eating, cooking and sanitation"


Both dwelling unit egress doors exit into the shared breezeway which is served by a single stairway that exits at grade level. One dwelling unit has a qualifying side-hinged egress door, the other dwelling unit has sliding-glass doors only.


Both dwelling units are roughly equal in size (around 2,000sqf.). One of the dwelling units is a shade smaller, but not by much.


Each dwelling unit has a kitchen, living, dining, sleeping and bathrooms, but only one of the dwelling units has a sleeping room labeled "master bedroom" (not that it matters in my opinion).


I'm getting conflicting views that the dwelling unit without the "master bedroom" is an attached "accessory structure" and that the building is therefore considered a 1-Family Dwelling with an attached accessory structure.


Q#1: Could the dwelling unit without the "master bedroom" be considered an attached "accessory structure"?


Q#2: If yes, when would the accessory structure cross the line and change the building classification as a 2-Family Dwelling?



If it helps, the building is located in Florida and is subject to the FBC.
 
It all depends on how it is intended to be used...."one family" means there is some connection where people may come and go from unit to unit....or it's a two family and you need to be protected from the strangers next door that you don't know are cooking meth....
 
MHO
It is a 2 family dwelling unit and the one unit has a non-compliant egress door since it is a sliding door and not a side hinged door
Are there 1- hour fire resistant rated walls separating the dwelling units? Or more importantly to protect the egress path of the shared breezeway exit?
