Dear kiwipaul, you haven’t really answered my question. As far as I can see, all the alterations & additions to common property must come with a special by-law, not just an AGM (we don’t have GMs or EGMs) agreed permission. Oh, and I forgot to mention the pergolas. However, I agree with you that NSW SSMA is open to abuse all the way. They (our EC & the SM) are clobbering an elderly widow with a heart condition at the Tribunal to remove her a/c from the common wall (she had it installed last year) to her back wall. All of the clobberers, bar the SM, have all three “improvements” & nary a special by-law in sight.
