Getting HOA to Engage in Resolve 89% Moisture

I need guidance in taking the proper stops to get the HOA to agree to discuss how to manage a 89% moisture reading on the meter. There was an obvious leak in the same area affected 4 years ago, also. It was supposedly resolved with caulk. There was no evidence of water intrusion. Now, I cannot witness eating flowing in; but the moisture is still present.

Honestly, I don't think you will get the assistance from the board until you do some investigation yourself to identify the cause.
The Association is probably of the mindset that they hired a professional to initially address it, they said it was caulking and replaced the caulk.

It could be as simple as condensation on pipes running in that wall (yes, should be no pipes in an outside wall, but it happens).

You might have to eat the cost and cut into the wall (from your unit) to see if the leak can be identified.

Here is a step before hiring a lawyer. Send the HOA a letter requesting it is put on the agenda to discuss. Plus would not hurt to take Tims advice in finding a solution. Otherwise it is up to your HOA to decide. Giving them an idea for a solution is helpful.

Is this an exterior wall? Are you in a condo building or a detached home?

Do you by chance have the documentation about the repair of 4 yeas ago? It might provide some clues. In addition, that repair may have now failed.

If your. structure is less than 10 years old it's possible there's a construction defect. One in our condo building was that the caulking at the window systems didn't have adequate weep holes, so moisture would intrude into our condo units via window seals, on ANY tiniest opening to the interior.
