Require high risers to install and maintain sprinkler systems...for a single dwelling home, I think it would be optional like solar panels.  Government gets involved into things that really aren't necessary and ignore things that are.  Get taller fire ladders and hire cliff climbing firemen to fight fires in high risers...better yet don't build any more of what you cannot take care of.  "If you build them, they will come!"  You got what you wished for C&C of Honolulu!
