A story from one user of http://strataboss.com.au A strata unit owner has got a problem with exhaust fan in the bathroom and requested a strata manager to send someone to fix it. An electrician came and fixed the issue. Next day the strata manager sent an invoice to the unit owner and requested a payment or proposed adding that amount to the levies bill. The owner went to http://strataboss.com.au , chose the problem location (bathroom) and the problem (exhaust fan) and got a c omplete information about who is responsible: If it is inside the lot it is the Owners responsibility. If it is mounted within "Structural cubic space" e.g. communal ducting or a false ceiling which is designed to carry communal pipes etc or outside the lot, then it is the responsibility of the Owners Corporation. In that case the fan is not inside the lot and therefore is Owners Corporation's responsibility. Instant savings of $100!
