in the realm of what’s already been done, one tiny step is OVE for conventional building:

…as well as other alternatives to stick-and-shitrock building mentioned on this page and elsewhere.
This stuff is all OK in many many places around the country and world. So if it’s not OK here, it sure ought to be and given all the precedents it ought to be one of the easier changes to make.
By “OK” I mean the county blesses it up front. No special anything needed, these methods are tested and proven, go do it.
We can currently do this stuff here, and, gotta get the architect/engineer stamp (if you can find one who will, and can afford it). Government-sponsored trade protectionism (like plumbing and electrical).
