A Typical Shed Costs Over Four Times Queensland's Licence Line, Under NSW's Insurance Line

The dollar lines a typical shed crosses

At Going Rate's prices, a typical backyard shed ($14,300) sits above the Queensland licence line and the NSW and Queensland owner-builder lines, and below the NSW and Victorian lines that start compulsory insurance. In Queensland, the QBCC says all contractors who do work valued at more than $3,300 need a licence, and a QBCC page reviewed in April 2026 still gives the same figure. A typical shed is 4.33 times that line. Queensland's owner-builder permit starts at $11,000 including GST, and the typical shed is 1.30 times that.

In NSW, an owner-builder permit applies once the reasonable market cost of the work, including labour and materials, is over $10,000 including GST, according to the NSW Government. The typical shed is 1.43 times that line. NSW also requires a written contract for jobs over $5,000, and the typical shed is nearly three times that.

The insurance lines sit higher. NSW requires a more extensive written contract and home building compensation insurance for jobs worth more than $20,000, and the typical shed is 0.72 of that. Consumer Affairs Victoria sets $16,000 as the value of domestic building work above which a hired builder must provide domestic building insurance, and the typical shed is 0.89 of it. Even the bottom of Going Rate's shed price range is above Queensland's licence line, while the top of the range crosses both insurance lines.

Kit or built: who each threshold applies to

Each line falls on a different person. The Queensland $3,300 line applies to the contractor doing the work, so buying a kit delivered to the door does not trigger it. The person you pay to erect the shed needs the licence if their work is valued at more than $3,300, and the QBCC counts labour, materials and GST in that value.

Owner-builder lines apply to the homeowner who builds or manages the job. The NSW test counts labour at reasonable market cost, so bolting the kit together yourself does not lower the value for permit purposes. The NSW Government says no permit is needed for work that does not require a development application or complying development certificate, so the value test only bites on a shed that needs approval. Owner-builders in NSW must also complete approved education once the work reaches $20,000. In Queensland the QBCC owner-builder permit applies to projects over $11,000 including GST, or $27,500 for farm buildings, and the QBCC's application page lists a shed by its size and intended use.

In Victoria, Consumer Affairs Victoria says owner-builders need a certificate of consent from the Building and Plumbing Commission before carrying out domestic building work over $16,000. The size rules below decide whether a shed needs approval at all. If yours does, check your state's owner-builder page for how the value test applies to it.

Shed size limits for council approval, state by state

Victoria allows a freestanding Class 10a shed without a building permit if its floor area does not exceed 10 m², it is no more than 3 m high, or no more than 2.4 m high within 1 m of a boundary, and it is not masonry, according to the Victorian Building Authority's practice note BP-01. A shed on a lot with no house must be the only Class 10a building and sit at least 9 m from the front street and 2 m from each side street.

In NSW, Armidale Regional Council's summary of the state rules puts the exempt shed cap at 20 m² in most zones and 50 m² in rural RU1 to RU6 and large lot R5 zones. The shed must not exceed 3 m above existing ground level, must be set back 900 mm from boundaries in most zones or 5 m in rural zones, and goes in the rear yard. The NSW Department of Planning classes these sheds as Class 10a, non-habitable buildings, and says they cannot be used as living space.

Brisbane City Council allows a shed of no more than 10 m² in plan area, 2.4 m high with a mean height of no more than 2.1 m, and no longer than 5 m on any side. Business Queensland says the state's 10 m² small shed allowance does not apply in a tropical cyclone area. WA allows 10 m² and 2.4 m, but not in wind region C or D, the Shire of Toodyay says. South Australia's Law Handbook lists sheds up to 15 m² as exempt, with some conditions. In the ACT the plan-area cap is 10 m² on blocks up to 500 m², 25 m² on blocks of 500 to 600 m² and 50 m² on blocks of 600 m² or more, with a 3 m height limit, according to ACT Planning.

What council approval costs for a shed

For a shed that needs a development application in NSW, the state's 2026/27 fee schedule sets a maximum fee of $153 for works up to $5,000. For works of $5,001 to $50,000, the fee is a $235 base plus $3 for each $1,000, or part of $1,000, over $5,000, so a typical shed DA fee comes to a few hundred dollars.

WA adds a Building Services Levy of $61.65 to any building permit for work of $45,000 or less, according to the WA Government. The Shire of Toodyay charges 0.32% of construction value for an uncertified permit, with a minimum of $121. At Going Rate's typical shed price, 0.32% falls below that minimum, so the $121 would apply. Brisbane City Council charges $78.80 to lodge building certification documents online.

Going Rate's building permit price ($6,250) covers every kind of project up to whole houses, so it is not a shed permit price. The same goes for a building certifier ($3,250), whose general price covers all project types. For a shed, ask the certifier for their own fee and add the statutory charges from the NSW and WA schedules above.

The wind rating and the slab

Steel shed kits are engineered to a wind class under AS 4055, which runs from N1 to N6 for non-cyclonic areas and C1 to C4 for cyclonic areas. Metroll's reproduction of the standard's table puts the ultimate limit state design gust speed at 34 metres per second for N1, 50 for N3 and 86 for C4. WA's Building and Energy regulator warns that the net design uplift at the top of walls can almost double between consecutive wind classes for houses with metal clad roofs.

After Cyclone Debbie in 2017, many garden sheds failed and became wind-driven debris, according to the James Cook University Cyclone Testing Station's report as covered by Insurance News. Queensland and WA both exclude cyclone regions from their small-shed exemptions. The Bureau of Meteorology defines a severe thunderstorm as one that produces wind gusts of 90 km/h or more, hail of 2 cm or more, or flash floods.

A kit price may not include the slab. Going Rate's price for concrete per cubic metre ($400) gives the material rate. As our own assumption, a 6 m by 6 m slab 100 mm thick takes 3.6 cubic metres, so the concrete alone costs 3.6 times that rate, before formwork, mesh and labour. Power is another extra. Going Rate's electrician price ($1,350) is a general figure across all jobs, so get a quote for running a circuit to the shed.

Deposits, contracts and the insurance gap

A shed priced under the NSW and Victorian insurance lines leaves the buyer relying mainly on the contract and the deposit. NSW requires a written contract for jobs over $5,000, and the NSW Government says the maximum deposit you can be asked to pay is 10 percent. Its page does not say whether that cap applies at every contract value, so check before you pay.

WA's consumer regulator has warned about shed sellers twice. In August 2020 Consumer Protection WA received 19 complaints in one week about Aussie Sheds Albany, from customers who said they had paid a total of $226,000 for sheds that were incomplete or not started. In July 2023 it reported 60 complaints against the Factory Direct group, which supplied and built patios, carports, garages and sheds, with $342,264 in deposits paid without the works being delivered. Individual deposits ranged from $448 to $6,617.

Consumer Protection WA's advice is to pay a small deposit upfront and only pay the balance when the work is complete. On a typical shed ($14,300), that means holding back most of the price until the shed is standing.

Shed, carport, patio or granny flat

At Going Rate's prices, a typical shed ($14,300) costs about twice a carport ($7,000) and about 1.1 times a patio ($13,000). A granny flat ($215,000) costs about 15 times a typical shed. NSW classes an exempt shed as Class 10a and bars its use as living space, so the granny flat price is the reference point for anyone who wants a backyard room to live in.

NSW exempts a carport of up to 20 m² on lots of 300 m² or less, 25 m² on larger lots in most zones and 50 m² on larger rural and R5 lots, according to the NSW Department of Planning. It must be at least 1 m behind the building line and no more than 3 m high, with setbacks of 900 mm from boundaries in most zones or 5 m in rural zones. At least two sides and a third of the perimeter must be open. The same fact sheet lists garages only as complying development, which needs a certificate.
