From what I saw when I was looking a RMH isn't allowed in WA state BUT a rocket mass cook stove can be allowed. Cook stoves with baking capacity have other regulations than heaters. I am not sure if the Walker Stoves were permitted, but they are in WA state.
Both Matt Walker and Ernie and Erica Wisner live in Washington state. They are some of the most active RMH innovators in the world, but I haven't heard of them having regulatory problems in this state.

The only way they would run into regulatory problems is if they were trying to get one permitted or selling a house (that failed an inspection).
And all I said previously was,
“ I’ve recently been hearing and reading that RMHs are not permitted in any state in the US”.
I never said they were, just that I have been reading and hearing that they were. I also don’t doubt some of the people who are sharing their stories about running into issues or being denied permits.
Any wood stove done wrong can be very bad, even deadly. And from my understanding (from what I have read), internal temps for RMHs can reach levels high enough to easily consume metals and reach them fast enough to crack/fracture ceramic... And if true, then that might cause problems in getting them permitted. That isn’t going to stop me from tinkering with them, but it is going to make me extra cautious and diligent in inspecting them at very regular intervals. If someone figures it all out before I get around to my own experimenting, great. If not, I’ll just keep in mind that they can be very dangerous and be extra cautious and understand that they might not be permitted.
Does anyone know if anyone has been able to get one or a design for one permitted in any state or country?
Or are they all just running them under the radar (with no official permitting).
