They strictly enforce against those who attempt to run a STR in any area where it is not allowed. 

If the legislation changes we can connect and I can point you in the right direction (to the developers that will have interest in paying you a sizeable lease for the land to develop a project).

Even if the tenant signs the CFK document and sets a time to move out, if they dont, you have no ability to enforce the contract.

So anecdotally they're ramping up enforcement.

If the guarantee is enforced, each individual with a 20% ownership stake would be liable for 20% of the outstanding debt.

I didn’t find anything offensive in the article and the city does very little to enforce tax collection.

Can you show me where it states that a local jurisdiction cannot enforce OO on a JADU? 

I'm not sure if this is always a requirement or recent due to legislation against steep rent increases.

So, the mortgage remains in place, with full liability as stated in the mortgage/deed of trust for the original borrower.I just completed a RARE subject to sale in which the bank holding our mortgage note agreed, via signed documentation, to allow the sale of the property without enforcing the “due on sale” clause.  

In an attempt to clean up the industry, legislation was written by those who 1) had never been lenders themselves and had no understanding of the industry and 2) their biggest campaign contributors were big banks (look up Barney Frank, Chris Dodd, and Elizabeth Warren's campaign contributors at the time and you'll see big banks).
