Fire Seperation M/S1/M

Re: Fire Seperation M/S1/M

Is this the point you are making Plans Examiner?

Kinda.

With nonseparated mixed uses, once you hit the threshold of 12,000 sf in a fire area, you require sprinklers by applying the most restrictive applicable provision of Chapter 9 (508.3.2.1). So I think that 2009 707.3.9 clears up the separated mixed occupancy problem.

But, throughout this discussion, I was reading instead of thinking. While reading your post, I had a duh! moment. :idea: Place the fire separation 1 inch (more or less) into the M area and make the separation according to 2006 Table 706.3.9. The single occupancy M is separated according to code. So that the result is one fire area as M and another that is mixed occupancy of a very small M plus the S-1.

I feel better.

Ooops. I realized I was quoting from the '06 but referencing the '09. I see that they did make a change in the wording in the '09 to include "mixed occupancies" in the text. I guess that does clear up some issues. I need to start weaning myself from the '06 soon anyway. Thanks Plans Approver.
