We rent a house in Queensland and discovered the back verandah/roof etc the owner built without council knowledge or permission. The concrete slab is shedding dust wich we are breathing in and covers inside the house. The owner sort of did a sealant spray but that was useless and he wont do it again. We shouldn't have to live like this. The roof is coated with tinfoil ( ilegal Im told) but nothing is done either by the owner or council. I'm the pig in the middle suffering stress/health etc now and in the future (which is what I fear) what can I do? I can't leave unless I want to pay rent and advertising. Do I have any rights in this place?
