I do not believe any propane company will care about a permit as install is to their standards. Run the line and let the company supply the tank.
My father is buying a year house on lake winni and he is curious about dealing with propane companys up there. Are their company's out their that if you buy the tank will they look the other way when it comes to filling them when their are no permits. The reasons for this is he wants to save money by having me to the install I am a licensed mass gas fitter and sheet metal worker but I have no license in NH so any anwser woul be great.
down in mass before you hook up you need to have the takes inspected by the local inspector but if we can do a home owners permit up there i will do that and if all else fails i will find one of the guys in the union local who has one up their to pull the permit it just makes it a pain in the ass
