As with so many things in strata, the word “reasonable” is not defined. However, Section 232(2) provides something of a guide in that it says if you haven’t received an answer from your owners corp to a request for action within two months, then they have effectively said “no”.
How does this apply in this case? It’s an indication of what might be considered reasonable. In the meantime, you can ask what steps have been taken.
If the strata committee or strata manager haven’t contacted contractors and asked for quotes for the work, then it’s “reasonable” to assume they have done nothing and you might want to consider initiating mediation at Fair Trading with a view to taking further action at NCAT if need be.
