You’ve budgeted, picked a spot on the paddock, and now someone mentions permits and suddenly the whole project feels like it might disappear into council paperwork. For a lot of Tasmanian farm sheds, it doesn’t have to. But the answer genuinely depends on what you’re building, where it sits, and how it’s constructed, so it’s worth knowing how the system works before you get too far into planning.
Most Prefabricated Farm Sheds Under 200m² Don’t Need a Building Permit
For a prefabricated farm shed that meets the Low Risk criteria, no building permit is required. That’s not a workaround. It’s how the framework is designed.
Under the Director’s Determination on Categories of Building and Demolition Work, a farm shed qualifies as Low Risk if it meets all of the following:
- Engineer designed and prefabricated of steel
- Less than 200m² in size
- Wall height no greater than 3.6m
- Ridge height no greater than 4.5m
- Maximum frame span between external supporting columns of 9.0m
- Single storey
- At least 3m from a boundary or adjoining building
- At least 6m from any habitable building on the property
A shed that ticks every one of those boxes sits in the Low Risk category. No building permit is needed, and an owner can build it themselves without requiring a licensed builder, a building surveyor, or an Owner Builder Permit. Council notification on completion is required for sheds over 36m², but that’s a notification form, not a formal approval process. See the shed permits overview for more on how that works in practice.
What ‘Farm Shed’ Means Under the Rules
The definition matters here, because not every shed on a rural property automatically qualifies as a farm shed under the Director’s Determination.
To meet the definition, the structure must be single storey, located on land primarily used for farming, used in connection with farming or to store farm vehicles (or a combination of both), and occupied by no more than two people at any one time. Farming means cultivating or harvesting plants or fungi, maintaining animals for breeding or selling their produce, or a combination of those activities.
If the property or intended use doesn’t clearly fit that definition, the shed may fall under a different building classification with a different set of rules applying to it.
How Tasmania’s Building Categories Work
All building work in Tasmania falls into one of three categories under the Building Act 2016: Low Risk Work, Notifiable Building Work, or Permit Building Work. A building permit is only required for Permit Work, the highest of the three categories. The category that applies to your build is determined by the nature of the structure, its size, location, and the conditions of the site.
Understanding which category you’re in is the starting point, because it shapes every other question about the build. The rules and approvals overview has a broader look at how this system applies across different shed types.
What Can Push a Shed Out of Low Risk
A few things can move a project out of Low Risk and into Notifiable territory, even when the shed itself seems uncomplicated.
The 6-metre rule catches people out more often than you’d expect. If the shed sits closer than 6 metres to a habitable building on the property, it no longer qualifies as Low Risk Work, regardless of size. That distance is measured from the shed to any habitable structure on the allotment.
The site location matters too. If the property falls within a designated hazardous area, whether that’s a bushfire-prone area, a landslip area, a flood-prone zone, a coastal inundation zone, or a coastal erosion zone, the work is automatically elevated to Notifiable Building Work. That means a building surveyor must be engaged before work starts and a certificate of likely compliance must be issued before construction begins. It doesn’t mean a building permit is suddenly required, but the process is more involved than a standard Low Risk build. The building codes page covers more background on how these categories interact.
And if the shed exceeds any of the size or height limits listed above, it may fall outside the Low Risk criteria for farm sheds entirely.
When a Building Permit Is Actually Required
For a prefabricated farm shed of 200m² or larger, a building permit is required. At that scale, a licensed builder, a licensed designer, and a building surveyor must all be involved in the project. An application for a certificate of likely compliance is required before the permit is granted, and the Building Administration Fee is payable at the point the permit is issued.
The Building Administration Fee applies when the estimated cost of the work is $20,000 or more, at a rate of 0.1% of that estimated cost. It’s collected by the council and applies across Low Risk, Notifiable, and Permit Work alike, just at different stages depending on the category.
Planning Approval Is a Separate Question
This distinction trips a lot of people up, so it’s worth being clear about. Planning approval and building permits are assessed independently and come from completely different parts of the system.
Planning approval is assessed by your local council under their planning scheme. Building permits are assessed under the Building Act 2016 and the Director’s Determination. There is no automatic connection between the two. A shed that doesn’t need a building permit may still need planning approval. Some projects need both. Some need only one. Some need neither. The only way to know for your specific property is to check both systems separately, starting with your local council on the planning side.
What to Sort Out Before Work Starts
Whether your shed ends up requiring a permit or not, a few checks apply to every build.
Check with your council on planning rules and setbacks from boundaries before settling on a location. Check your property title to confirm you’re not building over an easement. Contact Dial Before You Dig before any excavation to identify underground assets and services on the site. And if the shed will generate significant roof runoff, think through stormwater management early. No formal approval is required for stormwater management itself, but any connection to the stormwater system must be made by a licensed plumber.
Getting these sorted early keeps the build clean. They’re not complicated steps, just the groundwork that stops surprises later.
Getting the Right Shed Built on Your Property
For many Tasmanian landowners, a prefabricated farm shed under 200m² is a straightforward project from a regulatory standpoint. The Low Risk framework was designed for exactly this kind of build. But site conditions, the shed’s dimensions, and the property’s location all affect where the project lands in that framework, and those details are worth confirming before committing to a design.

Frequently Asked Questions About Farm Shed Permits in Tasmania
Do I need a building permit for a farm shed in Tasmania?
It depends on the size and construction of the shed, and the conditions of the site. A prefabricated steel farm shed that meets all the Low Risk criteria, including being under 200m², doesn’t require a building permit. A farm shed of 200m² or larger does require one. The full set of conditions is set out in the Director’s Determination on Categories of Building and Demolition Work.
Can I build a farm shed myself without a licensed builder?
For a prefabricated farm shed that qualifies as Low Risk Work, an owner can build it themselves without needing a licensed builder, a building surveyor, or an Owner Builder Permit. If the shed requires a building permit, a licensed builder, a licensed designer, and a building surveyor must all be engaged.
Does a farm shed still need planning approval even if no building permit is required?
Possibly. Planning approval and building permits are assessed completely separately. A shed that doesn’t need a building permit may still need planning approval from your local council, depending on the planning scheme that applies to your property. Check directly with your council, as planning rules vary across Tasmania.
What happens if my farm shed site is in a bushfire-prone or flood-prone area?
If the site falls within a designated hazardous area, including bushfire-prone, landslip, flood-prone, coastal inundation, or coastal erosion zones, the work is elevated to Notifiable Building Work. A building surveyor must be engaged and a certificate of likely compliance issued before work begins. Building in a hazardous area doesn’t automatically mean a building permit is required, but the process is more involved than a standard Low Risk build. The CBOS website at www.cbos.tas.gov.au has more detail on requirements for hazardous areas.
Do I need to notify the council when the shed is finished?
For a Low Risk farm shed over 36m², council notification is required on completion using Form 80 (Notification of Low Risk Work). For sheds under 36m², no notification is required. For Notifiable or Permit Work, different requirements apply through the building surveyor process.
Does the 200m² threshold apply only to prefabricated farm sheds?
The 200m² Low Risk threshold specifically applies to engineer designed, prefabricated steel farm sheds. A farm shed that isn’t prefabricated, or doesn’t meet the other conditions in the Director’s Determination, may be assessed differently. If you’re unsure how your planned structure will be classified, check with a building surveyor or your local council before finalising the design.
