"When I learned in late October that the International Code Council (ICC) voted at its annual conference in Baltimore to keep residential sprinklers on the book despite strong opposition from the National Association of Home Builders, I could not help but think what the leaders of the home builders group were thinking. The conversation inside their cigar-smoke-filled offices at the home builders group might have gone something like this: "Mr. Moneybags, we have bad news from Baltimore. The International Code Council voted 7-4 to keep residential sprinklers in the International Residential Code. This takes effect on Jan. 1, 2011, and requires sprinkler systems in new single-family homes after this date."
