State or local laws will probably need to be reviewed to tell for sure. You can call a local firehouse or building/inspections department for hopefully correct information. They can be purchased for $15-$25 each. Anyone can bring in a kerosene space heater at any time, so I'd just get the detector to play it safe. I like safe and I like cheap too, but safe takes precedence.
P.S. Guess I should get a gas detector now that i said that. Thanks a lot for your post (sarcastic)!
