I am at a loss as to how to address these issues. It seems a massive task and I don’t know where to start. Am I taking on too much ?
First of all get soemone with some strata savvy to inspect the place and tell you what among these many faults is a dead-set common-property “failure to maintain” issue.
Then get quotes from local contractors on cleaning the place up and repairing broken stuff.
Then put a proposal, with quotes, to your committee or strata manager to clean up at the very least, the base-level stuff. You might even investigate how much it would cost to get a loan to pay for it all.
If the strata committee or strata manage refuse or don’t do anything within two months, start proceedings at Fair Trading with a view to seeking Tribunal orders compelling the committee/manager to look after the property.
