In a Neighbourhood Residential Zone under Section 32.09 of the
Victorian Planning Scheme
no permit is required for keeping 1-2 animals, while a permit is required for keeping 3-5 animals. However councils often do not require a permit for 3-5 or even more animals. For example, Maribyrnong (03/2018)
allows keeping up to 10 hens without a permit. Some councils do not specify on their websites the number of animals that can be kept—aside from cats and dogs.
