This article continues our discussion on the rules and regulations for granny flats and dual occupancy developments in each Council throughout southeast Queensland and northern New South Wales.  Our team at Granny and Co have been working closely with Marc Joyce Town Planning to provide this information and will update this section again in the near future but in the meantime call us if you need clarification.

Logan City Council’s requirements for granny flats are set out in the Logan Planning Scheme. 

Logan actually has 3 distinct development options: secondary dwellings plus two different type of dual occupancy. To keep it simple, a secondary dwelling is meant for family use. If you want to rent out your granny flat then it becomes a dual occupancy… and you will have to pay a levy to Council.

The typical size limit for granny flats (secondary dwellings and dual occupancy: auxiliary) in Logan is 70m2 which this is enough for a very comfortable 2 bedroom solution… you may be permitted to build up to 100m2 if the size of your lot is more than 1000m2, which is basically a small home.

Here’s a link to a great checklist on Council’s website that helps to clarify the rules and regulations for building granny flats and dual occupancy developments in Logan Council’s catchment… but to make things easier we’ve summarised the main points below.
