Purchased an old unit in Lane cove sydney and settlement completed last week. We saw some dead pests in pre settlement inspection to which the agent said that the guys who removed previous owners belongings left the balcony door ajar leading to visible pests inside the unit. We accepted the issue as it was anyways a old worn out carpeted unit and we intended to replace it in future. We requested strata for approval of flooring change from carpet to floorboards. We arranged the quote from flooring guys and they confirmed maximum 2 days of work so we were satisfied we could move in our place by end of current place tenancy notice period. But nightmare started after the strata manager asking money and fullfillment of expensive by laws, first they asked for approx $300 for just requesting a meeting with owners co. for approval and no gaurantee they will approve. We were suggested by our solicitors that the strata manager is troublesome better to move into unit and get changes done later after being familiar to strata meetings. So we hired cleaners for deep cleaning the unit, even after thorough we could see roaches and spiders crawling around and dead stuck under carpets and in corners everywhere. It seemed hazardous to move into unit in this condition so we agreed to pay strata for approval meeting fee. Now they added another by law that if they approve we also need to pay for acoustics consultant report after installation. There is no guidelines on what standards they want to achieve from report. The by law just says, if asked, to provide acoustics consultant report certifying the acoustics properties of floor covering. The flooring we purchasing comes with 6 star acoustics certificate still the strata emphasizes on acoustics consultant report after installation. We spoke to few consultants who charge from 2000 upto Aud 3000 dollars that too can't give any gaurantee that strata will approve their report and not ask to redo the flooring. The flooring itself costing upto 5000 aud which we somehow pushed our budget to afford but acoustic engineer costs is just too much. We are first home buyers and exhausted all our savings already. This is becoming impossible to live peacefully in our own unit. Is there any law or support to protect us from this situation? We happy to do pest control in unit but since pests coming from outside building and cavities in flooring, even pest control guys won't give any gaurantee. I am worried moving into the unit in its current state will affect our health and belongings. What can we do?
