A dependent person’s unit (often called a granny flat) is a movable building on the same lot as an existing dwelling, used to provide accommodation for a person dependent on a resident of the existing dwelling. Recent changes in regulations now allow for small second dwellings to be built as permanent structures in many councils across Victoria.
Most residential and rural zones permit granny flats, but regulations vary by local council. Factors like lot size, building regulations compliance, and minimum garden area requirements will determine eligibility. Our team conducts thorough assessments to confirm if your property can accommodate a compliant second dwelling.
A planning permit addresses how the land is used and ensures your granny flat complies with local planning schemes. A building permit focuses on construction standards and building regulations to ensure safety and structural integrity. Both may be required depending on your specific situation and local council requirements.
The Victorian Government has introduced new regulations in some areas allowing small second dwellings to be rented to unrelated persons. However, this varies by council and depends on specific planning schemes. Our team stays current with these regulations and can advise on your particular situation.
Typically, obtaining necessary permits takes 2-3 months, depending on your local council’s processing times and any special requirements in your area. Humpy Co. manages this entire process, including addressing any building amendment requests or special conditions that may arise.
