In Oregon these days if you do not get change orders in writing they are not enforceable and the CCB will go after the sub hard..

I can't speak to the BP rules and how they are enforced and things like that, I was actually pretty surprised they banned him.

But IF the property in question is in compliance with all code, and provides a safe and secure environment, all problems are timely addressed and corrected, and the property is maintained on a professional level, then the investor who has a large capital investment in the property should be entitled to enforce any contracts providing him with the agreed to cash flow. 

FWIW I've enforced this fine many times over the last several years.

Central to my argument would be that making sweeping changes to the covenants themselves or changing how the covenants have been historically enforced only addresses the current problem indirectly. 

In the last few month we had 2 visits of officers from the Special Enforcement office, the first time I spoke with them they said they were just trying to see the airbnb listing to make sure it was in compliance with their requirements, I had guests in the room and I didn't let them in.

Just consider how you will enforce it.

I think they're justified, and I'm committed to helping them because this seems unfair, but I've never had to enforce the lease except for non-payment of rent.

Nobody monitors or enforces it, but you should understand this before jumping in.

If they were similar then pay it, if way off then tell them here is the quote and this is what we will reimburse - next time think 2x about ordering a service without our approvalI think you will find that in a life-threatening emergency such as this a judge will very happily hand you your rear end should you try to enforce such a policy or contract term against the person who is in danger.
