They're municipally operated here and we actually had a case a few years back where a small town that couldn't reasonably afford to operate their own fire department needed to make arrangements with a nearby larger town to have fire emergency response services cover them.

The larger town said sure, $50 per year per home. Small town had 63 people, but some refused to pay. Fire department said they weren't going to keep track of which houses were and were not covered, so they had to all be on board or none of them would be.

Naturally a home later caught fire and burned to the ground. Thankfully no one was inside at the time.
