You may have heard the term strata title in the context of leasing your duplex.
A strata title allows a duplex to split into two allotments so they can be rented separately. Without a strata title, your duplex must remain a single title property.
With a strata title duplex, there is an owners corporation, which is made up of the owners of the two separate sides. This owners corporation is responsible for shared duties including managing common property, raising strata levies, authorising renovations and repairs, and legal issues.
As a result of this complexity, there must be detailed records of all these shared responsibilities.
However, it is also worth noting that if you own both sides of the duplex yourself, you must pay double the fees.
