A dual occupancy is an attractive option for those looking to expand their living space or looking to rent out a property for additional income. These come in different forms and can be categorized as duplexes, townhouses, villas, or apartments.

Duplexes consist of two attached residences within the same building. They are often multi-level buildings.

Meanwhile, townhouses are attached dwellings. They share at least one common wall with the next residence.

Villas are often single-family dwellings built on the same lot. These have shared outdoor areas such as a pool or garden.

Apartment buildings have multiple units. However, each residence is separate from the others.

Additionally, consider the costs and taxes associated with owning or renting a property. Also, know how the properties may be divided or maintained when two or more tenants are living under one roof.

Additionally, local laws, regulations, and property insurance policies should be considered. This will ensure that both the owner’s and tenant’s rights are properly protected.

There is also an essential distinction between boarding houses and dual occupancy homes. Different regulations may apply to each, and it is important to understand the difference.

Certain strata or body corporate regulations or land size may also be limiting factors as to how this kind of home may be configured.

Duplex homes are becoming increasingly popular because they offer more flexibility. These include lower costs in terms of maintenance, taxes, and bills. These also reduce the risk of a bad tenant or difficulties with a tenant in one home.
