It's quite strict in Norway, and we even have inspections in private homes. We have lots of fire extinguishers, but now I realize we need to go through and test the fire alarms as well. I think it should have been enabled due to the amounts of smoke produced. We probably also should do regular fire drills.
Another thing is on the boats ... for different reasons the risk of a fire is much bigger on a boat than in a regular home. There are very few regulations and no inspections, but on the boat we have like four fire alarms and three CO-alarms plus various extinguishers.
