Granny Flat TAS Regulations – The Definitive Guide
If you are planning on building a granny flat in Tasmania, you must adhere to the regulations of your local Council. You may find these intimidating, so, here is a summary of rules for Granny Flats in TAS:
The Granny Flat rules in Tasmania indicate the maximum size must be no more than 60sqm or 30% of the total area of the main dwelling (whichever is less). They can be rented to anyone. There is no obvious rule regarding a minimum block size – there is actually no state-wide policy on what you can and can’t do, so the rules will vary between local Councils themselves.
There are still some standard regulations you must meet, such as building approval and an Occupancy Permit.

When planning a granny flat, choosing your design is exciting. But you must put a lot of careful thought into it, as prices can vary and increase dramatically.
For example, prices for a standard 1-bedroom portable home begin from $40 000. However, the average price for a 1 bed, self-contained granny flat ranges from $50,000 – $100,000.
I understand you need the granny flat to suit both your style and your primary dwelling.
However, the slightest changes can cause big changes to your budget.
So, take time to think about what plan is best for you.
When looking for a design, try finding one that offers you no additional charges to make changes to their floor plans, including:
Flipping/mirror reversing an already crafted design
Altering slightly from an existing plan
Next, once you receive a contract, ensure these costs are in your price:
Any alterations you made
Any inclusions you chose (i.e. your fittings and fixtures) *
*Note – this price may be an approximation, as the exact make/model/amount may not be known at the time.
The below costs might not be in your contract, so you might have to add them to your budget:
Obligatory inspections by a building surveyor (if not already included in your builders’ fee) Up to $2000
Approval fees – These vary depending on your local Council
Occupancy permit fee – Your building surveyor can advise you of this.
Sub-meters – If you want to rent out the granny flat, you may need to install new sub-meters for gas, water and electricity.
Gather 3 quotes per company to discover your options.
Installation fees – You will probably also need a licensed plumber/electrician to install new services.
Again, get at least 3 quotes before deciding.
If you find the price of building a granny flat in Tasmania too high for your budget, there are ways to lower the cost, including:
Reduce/remove prime cost items (i.e. fixtures/fittings with an estimated price) These can severely impact your final price
Keep it to the basics – Build a detached design that is integrated into the main home. Meaning, you do not need to include a laundry or kitchen if you can let the occupants use those in the main home. If not, you can always modify the design afterwards, making the unit self-contained yourself
Keep it simple but swell and choose a pre-designed transportable unit – see “Tasmanian portable buildings” below
There is no state-wide policy in Tasmania on what you can/cannot do when designing a granny flat.
So, the rules vary between Councils’.
However, there are some standard rules, including;
You must restrict the size to 60sqm or 30% of the total area of the main dwelling (whichever is less)
You will need building approval and an Occupancy Permit.
There are no restrictions on who can live in them – they can be rented to anyone. There is no obvious rule regarding a minimum block size, so I suggest you contact your local Council before a diy granny flat.
Regulations are similar when it comes to portables.
Tiny homes are also allowed without building approval, if:
Your tiny home has wheels and can be registered as a “caravan”.
However, your tiny home will require approval if:
You want to put it on a foundation, making it permanent.
