@Keala R. Kaanui:  Well single family homes should be in the discussion if you're going to force one group of residents to have sprinkler systems, but yet no one in the city is talking about it and you seem to be okay with that which makes your argument disingenuous.  Single family homes not being in the current discussion is an excuse.  One of the worst housing fires in the last 20 years took the lives of 7 people and there were no calls for mandatory sprinklers then.

There was another house fire earlier this year that took the lives of 2 people and there were no calls for mandatory sprinklers for that incident either.  Yes I am sure because I googled it and found a site with fire statistics and Civil Beat also reported the low number of fires and fire related deaths for condos.  As for your last question, I could use that same argument for houses and yet they have zero requirements and account for over 95% of all fires!
