Wait, these rules aren't something that are enacted and enforced at an individual city / town level? These are state-wide zoning(?) rules being applied universally to all jurisdictions in the state? If so, that does seem obnoxious..
(I don't own land so I am very unfamiliar in how zoning regulation plays itself out, so apologies ahead of time.)
Please tell me what part of the country this is so I can avoid it.
However, rules like these are "zoning/planning" and are usually set by the city or county, not the state.
The county shifting to Idaho is likely to have no effect on that regulation.
FAR's are why Palo Alto had to bring in regulations on basement sizes (the majority of the house was underground!), and why Zuckerberg is having problems with his renovation plans.

There was one guy talking about Jesus but for the most part we're pretty sure he wasn't an anti-masker. Actually all of our neighbors have told us they wear a mask by the way. So yeah, it's really just getting away from the legal requirements that the populated places need but forget to loosen the rules far away.
Now every county is different so take my input as a grain of salt.
