Unapproved Structures in Tasmanian Property Contracts

Q: Can an unapproved structure be legally regularised in Tasmania?

Yes, under the *Building Act 2016* (Tas), an owner can apply for a Certificate of Substantial Compliance through an accredited private building surveyor. However, the structure must be inspected, documented with engineering drawings, and proven to meet National Construction Code performance requirements, which can be difficult or impossible if structural footings, framing, or waterproofing cannot be visually inspected without intrusive demolition.

Plain English Definition

"Unapproved Structures" means any building, residential extension, carport, deck, retaining wall, or outbuilding constructed without the mandatory permits, plans, or completion certificates required by local government authorities. In the context of a Tasmania property contract, it refers to improvements on the land that breach statutory requirements under local planning schemes or state building regulations. Because municipal councils retain the statutory authority to issue enforcement orders against the current registered owner regardless of who carried out the unauthorized building work, these illegal improvements represent a significant legal and financial liability for unwary purchasers.

Who This Affects

Property Buyers: Suffer the immediate legal and financial burden of inheriting unpermitted works, which can lead to unexpected demolition costs, council fines, or the requirement to fund retrospective engineering certifications after settlement.
Property Sellers: Face potential contract renegotiations, delayed settlements, significant price reductions, or outright termination if standard contractual warranties regarding building compliance are breached.
Mortgagees and Insurers: Risk holding security over non-compliant assets that may fail bank valuation criteria or suffer from completely voided insurance policies in the event of fire, structural collapse, or storm damage.

The Danger Zone: Buyer's Risk

When you acquire real estate containing unauthorized works, the local council does not waive statutory compliance merely because you were not the party who built them. The legal risk passes directly to your title upon transfer.

Council Demolition Orders: Under the Building Act 2016 (Tas), a municipal council can issue an emergency order or a building order requiring an owner to demolish an unsafe or unapproved structure within a specified timeframe, frequently costing between $10,000 and $35,000 in demolition and disposal expenses.
Hefty Regularisation Costs: Seeking retrospective approval through a Certificate of Substantial Compliance is a complex, expensive process that requires hiring private building surveyors, structural engineers, and draftsmen, often totaling $5,000 to $12,000 even when the underlying structure meets engineering standards.
Denied Insurance Claims: Insurers operating under standard home and contents policies routinely refuse to pay out claims for structural damage, fire, or third-party injury caused by or related to uncertified building modifications, leaving the property owner personally liable.
Financing and Valuation Collapse: Mortgage lenders conduct strict risk assessments, and if an unapproved habitable room or major extension is discovered during a pre-settlement bank valuation, the lender can withhold mortgage funds, jeopardizing the buyer's deposit.
Plumbing and Environmental Non-Compliance: Illegal wastewater, sewer, or stormwater connections carry substantial statutory penalties from TasWater and local councils, potentially requiring complete excavation and relaying of drainage infrastructure at costs exceeding $15,000.
Compromised Resale Value: When you eventually choose to sell the property, prospective purchasers and their conveyancers will inspect council records, which inevitably leads to requests for price reductions, repair requirements, or lost sales.

What to Check Before Signing

Request a Section 337 Council Certificate: Order a full certificate under Section 337 of the Local Government Act 1993 (Tas) to verify the registered history of building permits, plumbing permits, certificates of completion, and any active abatement or enforcement notices issued by the municipal council.
Compare Council Plans to the Physical Site: Obtain copies of the original council-approved plans and inspect the grounds thoroughly to ensure every shed, covered veranda, internal wall alteration, and detached studio matches the stamped architectural drawings.
Engage a Licensed Building Inspector: Hire an independent building inspector licensed under the Tasmanian Occupational Licensing Act 2005 to assess whether renovations show signs of substandard DIY construction or unpermitted structural changes.
Insert a Protective Special Condition: Require your conveyancer or legal practitioner to draft a tailored condition into the contract making the purchase subject to your satisfaction with council records or requiring the seller to obtain retrospective approvals prior to settlement.
Examine Owner-Builder Statutory Warranties: Check if any construction within the previous six years was carried out under an owner-builder permit, which triggers specific disclosure duties, insurance obligations, and statutory warranties under Tasmanian legislation.

Key Tasmania Rules

Under the standard Tasmanian Contract of Sale jointly approved by the Law Society of Tasmania and the Real Estate Institute of Tasmania (REIT), the legal principle of caveat emptor ("let the buyer beware") fundamentally controls the physical and regulatory condition of the property. While the vendor provides limited standard warranties—such as having no knowledge of outstanding council notices or demolition orders at the exchange date—the standard contract does not guarantee that every historical outbuilding, garage, or pergola possesses formal council sign-off. Compliance enforcement is driven by municipal authorities under the Building Act 2016 (Tas) and the Land Use Planning and Approvals Act 1993 (LUPAA). If unpermitted building work is uncovered after the contract becomes unconditional, the buyer cannot automatically rescind or claim compensation without an explicit, negotiated special condition.

Real-Life Tasmania Scenario

Hannah signed an unconditional contract to purchase a character cottage in Launceston for $595,000, attracted by a newly built rear studio advertised as an ideal home office. After settlement, a neighbour lodged an amenity complaint with the City of Launceston, prompting a council compliance inspection that revealed the studio had been erected directly over an unmapped stormwater line with no building permit, plumbing authorization, or planning consent. Because the standard Tasmanian Contract of Sale provided no contractual warranty regarding universal building approvals, Hannah had no legal recourse against the vendor and was forced to shoulder the financial fallout herself. The council issued a strict enforcement notice, and because the structure could not be engineered safely over the stormwater infrastructure, Hannah spent $16,800 on contractor demolition fees, council inspection levies, and site rehabilitation. Due diligence on council property files must always take place before signing an unconditional contract rather than relying on real estate marketing descriptions.

Frequently Asked Questions

Does a Section 337 Certificate in Tasmania guarantee there are no unapproved structures?

No. A Section 337 Certificate only reports on information already known to the local council, such as existing permits, certificates of completion, and formal notices issued. If previous owners erected a deck, shed, or extension without ever informing the council, the illegal structure will not appear on the certificate, which is why a physical comparison of council-approved plans against the land is critical.

Can an unapproved structure be legally regularised in Tasmania?

Yes, under the Building Act 2016 (Tas), an owner can apply for a Certificate of Substantial Compliance through an accredited private building surveyor. However, the structure must be inspected, documented with engineering drawings, and proven to meet National Construction Code performance requirements, which can be difficult or impossible if structural footings, framing, or waterproofing cannot be visually inspected without intrusive demolition.

Does the standard Tasmanian Contract of Sale provide a cooling-off period if I find an illegal shed?

Tasmania does not have a mandatory statutory cooling-off period for real estate contracts, unlike several other Australian states. Once you sign a standard contract and it is accepted by the seller, you are legally bound to complete the purchase, which means you cannot walk away simply because your conveyancer later discovers an unapproved outbuilding on the property.

Will a bank refuse mortgage finance if a property has unapproved structures?

A mortgage lender may reject or conditionalise your loan application if their valuer identifies significant unpermitted building works or unsafe alterations during the valuation inspection. Lenders require unencumbered, readily marketable security for their loan, and discovering uncertified habitable spaces or severe planning violations frequently leads to reduced valuation figures or an outright refusal to advance funds at settlement.
