There are a few design directions the project may go. One option is to identify it as a separated mixed-use building, which requires fire-rated separations between occupancy types and incidental use areas. A second option is non-separated mixed use where the architect / engineer need to verify the type of construction and building height and areas are compliant. If utilizing non-separated mixed use, the incidental use table does not apply. Also, the inclusion of the retail / commercial use will require NFPA 13.
To go a little further, whether using separated mixed-use of non-separated mixed-use, separate systems are not required per building code, but may be advisable to keep the commercial and residential areas separate.

But the entire design has been per 13, albeit with the residential provisions of the standard.

Four storey 8 unit residential building, in bid stage, just got notification that one unit, half the ground floor, will be zoned for commercial use. I'm at odds if this changes the building to mixed-use or not. I've asked the gc if he's still applying as an R2 and he's not sure, architect in on vacation (go figure). I'm leafing through our building code (ICC-03) right now to see if this qualifies as ancillary with regards to design (13 vs. 13R) but I just thought I'd ask the masses with a little time on their hands how this would resolve under their current codes. Often we have similar provisions and interpretations and I don't have the workbook, tabs or supplement yet for ours. We're new to this edition. I'm able to refer to 13 for design in areas like Basements but still base the remainder of the system under 13R requirements and our old code gave little guidance as to percentages with regards to areas outside of the use group. I'm wondering if, disregarding permit application for now, the addition of one of the 8 units from residential use to commercial use (will be a store) will effect the design.
