Re: Closers on 20 minute rated doors

If this is just a single family residential dwelling with no attached garage where are they pulling the requirements for fire resistant walls, ceilings and doors at a basement level from? The only place in an R-3 res dwelling where fire protected walls are required is when the building is within a certain distance of the property line. The 2007 CBC has many of the same requirements at the 2006 IRC, see attachments.
