Get a defect report from an independent inspector, give the developer formal written notice listing every defect with photos and dates, and demand rectification. If they refuse, escalate to the state building authority and ultimately the tribunal or court for orders.
Time limits matter — most states have a 6–10 year statutory warranty period. Don't accept verbal promises or partial repairs that reset nothing. Get a strata lawyer or specialist defect consultant involved early — defect litigation is technical and the developer will be well-advised.
Compare written fee proposals from strata managers covering your building — free for owners corporations, no obligation.
