I bought off the plan in 2000. Within 2 years we had to raise a special levy to complete works due to not meeting Australian building code standards. Builder said not his problem. Though we gained access to paperwork from council certifying the complex for habitation there was no name on the paperwork. Just council stamp. Work needed to be completed due to the insistence of our insurer. Issues in individual units too. Builder closed down – but opened up another business.
Cars with faulty airbags must be fixed at no cost to owners – dangerous. And retailers who sell uncertified electrical appliances/products face heavy penalties. But apartments/strata…you’re on your own.
