If you ever drive past a refinery and see a flame at the top of a very tall stack, that is LP Gas.
When they make other fuels LP Gas is a byproduct of the refining process and when they run out of storage space, they just throw it away through that stack. So in my opinion LP Gas doesn't really cost anything if the oil companies are just throwing it away. Where the actual cost for LP Gas comes from is the insurance and the transportation costs.
I’m sure there is a raw material cost for LP gas but the lion's share of the LP Gas price is insurance. That is because it is a really dangerous fuel. When it leaks out of a pipe it is heavier than air so it does not rise up out of the house through the doors and windows like natural gas would. I have seen a house blown off the foundation from LP gas pooling in the basement when the well pump switch ignited all that leaking fuel. The homeowners were hospitalized as a result of the explosion and the home was a total loss.
So if the insurance company says that the cost for them to insure the LP company that delivers the fuel to your home is a higher price to provide 2 PSI, and the LP company doesn’t want to provide 2 PSI in your home as a result, to save YOU money on the cost of your fuel, You can’t argue with that.

After you make that expensive repair and you still have the same problem, What will you check next?

I have never in my 37 years seen a propane company install anything beyond the 2nd stage reg outside the building. Everything inside the space is up to the plumber and/or HVAC.

There is no reason to need 2psi propane inside the house. The reg on the outside reduces the 2 psi to 12"wc which is plenty of pressure especially with propane.

That is an incredibly false statement. Not everybody wants to run 1" lines across the whole building when it's a fraction of the price and half the labor to run 1/2" and add a 3rd stage reg. Might as well knock it down to 12" with the first stage at the tank, by that logic. Obviously a small home with a 40k forced air furnace and nothing else gas is a different story, but in the age where everybody has a 199k tankless as well as a boiler and/or furnace w/ fireplace and gas range, 2# inside is almost a necessity.

I've seen many 2 psi MP regs. indoors. you must extend the vent to the outdoors with a 10ft. clearance from a source of ignition. These are very large houses with multiple furnaces, tankless DHW, oversized cooktops, etc. If you can group the high demand appliances in one part of the house you can run one larger diameter riser from an outdoor MP reg. to a manifold then branches to the individual loads. You can get away with skinny pipe on long runs with LP but watch for high velocity whistling on those runs. Keep it within reason and show the sizing charts to the gas piping so it will know that it is supposed to behave and not unfire if you sized it appropriately and not to many offsets. Also, don't make sudden drops from large diameters to smaller- step them down with bell-shaped reducers. Besides, bushings not allowed with gas.

MA does not allow anything over 1/2 psi in a house

Which is a little less than 12 inches of water column if memory serves?
