I then went through the three-step "grievance" procedure where the District basically blew me off.

I WOULD however, pass this along to your legal counsel and do no more unless she files a grievance in housing court (which is closed across the whole country right now).

Is there financial distress, do they have some grievance against the HOA, do they think they’re on auto-pay, etc.Could be an opportunity for you depending on the circumstances.

Based on Article 16(Specifically 16-3)"All dealings concerning property exclusively listed, or with buyer/tenants who are subject to an exclusive agreement shall be carried on with the client’s representative or broker, and not with the client, except with the consent of the client’s representative or broker or except where such dealings are initiated by the client.)" of the Code of Ethics.Personally I have never called the board or filed a grievance so that is not my stance.

I'm confident they will be able to proceed without any grievances from the tenants as they've been very understanding and reasonable with everything so far. 

While we have variance in things there seems to be universal agreeance that we need address of our grievances, across the nation in every state, county and city. 

The kind of activities will involve:Buy/Sell transaction documents review in conventional wayForeclosure/Auction documents review(Potentially) Land parcel subdivision, working with local municipality on tax grievances, Easement negotiations etc. 

This gives them the ability to voice their grievances, without getting my info.

I would tell the tenant to direct their grievances to the codes department and that if there is a real violation then you will fix it within their prescribed amount of time.

His grievance with the landlord, assuming he's got no legal interest in the property, is not your problem today.
