I'll chime in with my opinion. Does 13 REQUIRE the 3,000 sf DA? The section that requires the 3,000 sf DA [11.2.3.1.4(3)] is part of section 11.2 "Occupancy Hazard Fire Control Approach". Residential sprinkler design is a separate section (11.3.1) and is not subject to the requirements of section 11.2.
SHOULD 13 require the 3,000 sf DA? The underlying premise of 13 is property protection. Allowing residential sprinklers to be used in dwelling units adds to the life safety aspect of the system, but its' still primarily a property protection system. For that reason, I can't believe it's the INTENT of 13 to not require the 3,000 sf DA. Property protection is property protection, whether the sprinkler used is a SSP or residential. That's the exact reason why a .10 gpm/sf density is required when using residential sprinklers. So even though I don't think the 3,000 sf DA is required, I think it should be. Exit soapbox, stage right.
