A dual key dwelling
(also known as dual occupancy or auxiliary dwelling) is a property that contains two dwellings on one lot. Not to be mistaken for a duplex (which can be titled separately), a dual key dwelling must be owned by the same person on one land title. In a nutshell, a dual key dwelling:
• Is two dwellings on one title (usually a main house, and a smaller auxiliary dwelling).
• Has separate entrances, self-contained living areas, and separate water and electricity meters.
• Must include a certified and approved firewall for additional safety.
• Is not restricted by body corporate rules, not does it incur strata fees.
