While that's what the headline says, it appears that what the courts have said is that the city has the authority to require that someone in the city be connected to the city water system. The headline is really saying ".... Illegal If Cities Decide To Make Them Illegal."<p>It does not say that off-grid homes are illegal in Florida. (If it did, there are any number of off-grid homes on islands which would also be made illegal.)<p>This ruling is little different than when I was in Miami and the city required that once a sewer line was put in the street then all of the houses were required to hook up to it instead of using septic systems.<p>Or when I was in Tallahassee and a nearby town moved to city garbage pickup instead of individual trash disposal. I vividly remember the newspaper image of the woman protesting that her monthly trash fit into a tin can, and she didn't see why she had to pay for it.
