Roland, I agree the QR sprinkler reduction is applied to whatever size the initial design area is determined to be. We apparently disagree on the minimum size of the initial design area.
My position is that when utilizing the Density/Area Method, section 11.2.3.2.1.2 and the curves of Fig 11.2.3.1.5 dictate an initial DA of nothing less than 1500 sf. The DA increases and reductions are then applied. In Rich's original scenario, this would result in a revised DA of 900 sf and a density (assuming light hazard) of .10 (per section 11.2.3.1.8 (1)). If Rich's building had been 800 sf, then the DA would be the entire 800 sf. So let's ignore section 11.2.3.2.1.2. As a designer/contractor wanting to retire early, why wouldn't I select a DA of 200 sf and then reduce it by 40% to 120 sf (regardless of whether it's a 1,000 sf building or 60,000 sf)? What section in the standard differentiates between buildings larger than 1500 sf and those smaller than 1500 sf?
