There are two trade associations under the ARDA umbrella, one for developers and one for owners. The optional contribution to ARDA you see on your annual maintenance fee statement does go to the owners division. What is interesting when you look at the list of the board members of the two "separate" organizations they are essentially the same people and/or companies & organizations. This in my opinion is a built-in conflict of interest. Regarding their specific efforts, what I have seen over the years is that they are always in lock-step in their positions when they lobby a state legislature or US Congress. Often what is pushed in the interest of the developers is not best for owners. Check it out for yourself online.
