JT said: “First of all, the Executive Committee can’t force you to do anything although they can apply to the CTTT for orders (which they are unlikely to get in the circumstances you describe). Secondly, they have no comeback over non-common property changes that were made within your apartment by you or anyone else.”
JT, these points sound simplistic and unlikely to be true just on the surface of it. Are you sure? What if there was a load-bearing wall dispensed with or something affecting the structure? Or, say, the balcony was re-tiled and was now higher than the inside so water could drain in? There are a thousand things that could have been done affecting the integrity of the building. (Or something involving wiring issues, such as the ones which it seems may have caused the awful fire.)
