ACC member disclosed information

What do your documents say? Your bylaws may have procedures for certain committees like an ACC. If not, they usually state the board has the authority to establish or disband advisory committees, which should also include dictating what they're responsible for. Committee members also serve at the pleasure of the board, so if someone does something inappropriate, you shoukd take your complaint to the board with proof of wrongdoing.

In this case, I'd also like to know what was disclosed. Disclosing design standards for certain changes like paint colors shouldn't be state secrets- all homeowners should know them. If the issue concerns a request for an exception, that might be a problem, but once again, committee members can be outvoted.

Certainly ACC modification applications should be confidential and not shared with other homeowners. Any discussion of the details of an application should stay within the ACC committee and the Board of Directors, not discussed as gossip with other homeowners.

It was discussed with a different homeowner. Why the ACC is rejecting the project and why it was delayed for building.
Several submissions were discussed. Contacted the board member privately and they dismissed the whole issue. It has now been sent to the association, so it won’t be ignored or dismissed. I even had emails sent to me about other committee issues.
I was on an ACC at a previous neighborhood and we couldn’t discuss these things with anyone. This is why I am asking.

Correction: I meant ACC member above, not director

I think an application for an architectural change is an association record. Under TPC 209, I expect owners have a right to review such a record.

If the ACC is trying to be secretive here about its reasoning, this is a mistake.

Information about decisions on another home was disclosed to me and why they were denying it. They sat on the decision purposely because of the color and style of the home. They were supposed to use earth tones, blue, they denied it. blue is an earth tone. They didn’t like the modern with the metal frame, so they made them change it to stucco. Metal buildings, barndos, are approved in this neighborhood.

Shouldn't all ACC meetings be public? In Florida in most associations, we are required to post notice of the meeting and the agenda and keep minutes for the official record.

If the ACC is keeping secrets or having secret meetings or discussions, then I think that's the problem and not the fact that something was disclosed.

Can you please just straight up explain what your concern is here? Are you annoyed by something and wondering if you are wrong to be annoyed? If so, what annoys you?

What harm, of a legal nature, was done? Please be specific.

Do you think homeowner ARC submissions should not be disclosed to owners?

If so, you are mistaken.

Do you think the committee member who disclosed such-and-such to an owner should have gotten the committee's permission?

Best practices for best communications and optimal functioning: The committee member should have gotten the committee's permission.

On the other hand, if the committee had then refused to share this information, then this is a problem.

'Best practices' are largely not enforceable in court.

As far as rules are concerned:

Texas statutes do not speak to such a specific scenario.

Texas statutes do speak to the fact that owners have a right to inspect "association records." A homeowner ARC submission becomes a part of "association records," which others legally have a right to inspect.

To my understanding, there is nothing legally wrong about it.

Ethically, perhaps.
