Things You Need to Know About Owning a Duplex in Sydney

11 September 2020

Choices for property types like single-family home, townhouses, multifamily, apartments — can start to feel like an endless smorgasbord of decisions, and when you finally think you have a grasp on all the diverse property types, they drop another term on you: duplex.

Presently, don’t stress on the fact that you don’t have the foggiest idea what a duplex is — it tends to be complicated. Also known as twin homes, side-by-sides, or multifamily dwellings, duplexes are homes that more than one family resides in. You may even think of duplexes as two houses at the cost of one. And with almost one in five families living in a type of multifamily home, duplexes are as popular as ever today.

What Makes A Property A Duplex?

There are several criteria that a property has to meet for it to be called a duplex. The configuration is the primary component that defines a duplex. A duplex is a property containing two living units in a single building. Typically, those units are symmetrical and of equal size, and either sit one next to the other or are separated into first-floor and second-floor units. The key thing to remember is that a duplex will usually share either a wall (one next to the other or twin home) or a story and ceiling (upstairs/downstairs).

Even though the two units are in the same structure, regularly looking something like a single-family house, each unit has its entrances and exits, kitchen, rooms, bathrooms, and capacities like a townhouse or even as an apartment. Regularly, there are shared spaces within the property, for example, a backyard or garden space, laundry, and storage. Parking is either shared or assigned, depending on the individual landlord and tenants.

Duplex Proprietorship

Duplex proprietorship breaks down into two categories. With a classic duplex, one individual or family possesses the two units of a property. In any case, the situation with twin homes is extraordinary. Twin homes look like duplexes — they usually sit next to each other and share a wall — yet there are two proprietors of the property. Each unit has a proprietor, instead of the two units being claimed by one individual.

Land, Or ‘Parts’

There is a distinction in the responsibility for the plot of land while distinguishing between a duplex and a twin home. With a duplex, there are two units on one part; with a twin home, there are two parcels, so each proprietor has their parcel or plot of land.

On the off chance that you went on the region assessor site and you look into a particular address, a duplex will have its address, however, would also be its parcel. A twin home could be possessed by either two unique individuals or one individual, however, it would at present be recorded as two distinct parcels.”


For a twin home, each proprietor is answerable for the upkeep of the property and land on their side, including landscaping, painting, and maintenance. With a duplex, the single proprietor is liable for the maintenance of the whole property.


With a twin home, the individual proprietors should also get their insurance strategy for their side of the home.


Duplexes are at times mistaken for maisonettes. The term maisonette originates from a French word meaning “small house.” While a maisonette may have a few characteristics of a duplex, it is usually an apartment that possesses two stories.
