I replied to you before the parent was edited.

I think we are pretty on the same page regarding regulations. Safety is important. But forbidding density via setbacks, parking minimums, and certain types of housing is what bites us. And there are some regulations enacted in the name of.safety, which create nonstandard requirements where a prefab home factory must either special case that one state/locality, or forbid selling there.

As an example, any factory-manufactured home sold in California must have a sprinkler system. Sprinkler systems are expensive, and while they're very valuable in large shared buildings, I question whether they are necessary to mandate in single family homes.

Of course this isn't targeted at manufactured homes; California mandates this in every new house.

But this fragments the manufacturing of homes and causes issues with getting the efficiencies you would expect from a factory. Multiple SKUs need to be built.
