SPP amendment 01/2026 - Secondary residences
What is this about?
This draft State Planning Provisions (SPPs) amendment proposes to increase the allowable gross floor area for a secondary residence from 60m2 to 90m2, and further clarify the requirements for secondary residences (ancillary dwellings or granny flats).
The Minister has issued Terms of Reference for the draft amendment 01/2026 as part of the process for an amendment of the SPPs under the Land Use Planning and Approvals Act 1993 (the Act).
This draft amendment will apply in council areas where the Tasmanian Planning Scheme is in effect.
The stages of the amendment process are explained in more detail within the Lifecycle section below.
Who is involved?
The State Planning Office prepares the amendment for the Minister. Local councils and relevant State agencies and authorities, and the Tasmanian Planning Commission are consulted during preparation of the draft amendment. The Tasmanian Planning Commission conducts a formal review process with public consultation, then advises the Minister whether the amendment criteria are met. After considering the advice, the Minister makes the final decision.
Timeframe
The project commenced in February 2026 and is expected to complete in the second half of 2026.
More information on the process for preparation and assessment of draft SPPs amendments under the Act is available in the State Planning Office's simplified flow chart, or the Tasmanian Planning Commission provides a more detailed flowchart on their website.
Background
The SPPs are the statewide set of consistent planning rules in the Tasmanian Planning Scheme (TPS). The SPPs came into effect on 2 March 2017.
A comprehensive review of the SPPs was completed in 2023 as part of the 5-yearly statutory review required under the Act. The review identified a variety of potential amendments to the SPPs and more detailed reviews.
The Government’s proposed amendment to the SPPs to increase the gross floor area for secondary residences forms part of the Government’s commitment to provide more housing options for Tasmanians.
Increasing the maximum floor area from 60m2 to 90m2 will enable more liveable, adaptable small homes consistent with other jurisdictions. It will provide more flexible design options for adding an extra home on land already used for a single dwelling, providing options for ageing in place, multi-generational living and smaller household rentals.
Frequently asked questions
What is a secondary residence?
Secondary residences (often referred to as ancillary dwellings or granny flats) are small, self-contained living units located on the same site as the primary dwelling (a single dwelling on a lot).
They can be attached to, contained within, or a separate structure to the primary dwelling.
They share existing reticulated services with the primary dwelling (e.g. electricity, water, sewer and gas) along with any driveway and car parking spaces. Secondary residences may have their own laundry facilities or share them with the primary dwelling.
When will I be able to build a 90m2 secondary residence?
The State Planning Provisions (SPPs) currently allow for a 60m2 secondary residence.
A change to the State Planning Provisions part of the Tasmanian Planning Scheme (TPS) needs to happen before you can apply to build a 90m2 secondary residence.
A change to the SPPs must follow the amendment process in the Land Use Planning and Approvals Act (1993). The process for this amendment started in February 2026 and will take at least 7 months until it comes into effect. The time taken to complete the amendment process can vary depending on several factors, such as the number and complexity of submissions received.

The Minister has prepared SPPs amendment 01/2026 and is consulting with all councils, relevant State Agencies and Authorities, and the Tasmanian Planning Commission as the first step in the SPP amendment process. Their feedback will inform the final draft SPPs amendment ready for assessment by the Commission.
In the next step, the amendment will be available for public viewing and comment on the Tasmanian Planning Commission website. See the steps in the Lifecyle below.
Do I need planning approval?
If the zone permits a single dwelling to be built, a secondary dwelling can also be added. You may not need planning approval if your project meets the requirements for a secondary dwelling and all of the development standards for your planning zone. Planning codes may also apply to your property, meaning your project may need to meet extra requirements such as flood-prone areas or historic cultural heritage.
Please check with your local council planner to make sure you are clear on what you will be able to do with your property.
Do I need building or plumbing approval
Yes, building and plumbing approval will be needed. Please check with your local council for advice on your project.
