My understanding is that solid motors are regulated as explosives and can only be manufactured in a licensed explosives factory, making it impractical for amateurs. On the other hand, I'm not aware of any specific laws regarding liquid or hybrid motors. (You would still need to clear it with the fire department, Natural Resources, etc. but I don't think that would be too problematic if you have your act together.)
