Shipping containers are versatile structures that have gained popularity for various purposes, including being used as dwellings, offices, and storage units. However, when it comes to complying with building regulations, many people wonder if building approval is required for such containers. Let’s delve into the relevant legislation, interpretation, and considerations to help you understand whether building approval is necessary for a shipping container used as a dwelling, office, or storage.

Understanding the Legislation:

The Building Act 1975 (BA) and Integrated Planning Act 1997 (IPA) form the legal framework that governs building and development in many regions. It’s important to consider the provisions outlined in these acts to determine the requirements for shipping containers used in different capacities.

Definition of Building Work:

Under the BA, building work encompasses various activities, including building, repairing, altering, underpinning, moving, or demolishing a building or structure. It is crucial to understand this definition as it forms the basis for assessing whether a shipping container falls within the scope of building approval.

Fixed Structures and Buildings:

For a structure to be considered a building under the BA, it must be a fixed structure, partially or wholly enclosed by walls, and roofed. The permanency, size, intended use, and utility connections are key factors to determine if a structure qualifies as a building. Case law examples have shown that even if a structure is capable of being moved, it can still be classified as fixed if it exhibits elements of permanency.

Shipping Containers as Fixed Structures:

When analyzing the context of a shipping container placed on land for ongoing use as a dwelling, office, or storage, the Department responsible for building regulations considers such containers as fixed structures and therefore falls within the definition of a building under the BA. This means that building assessment provisions and building development approval may be required.

Structures and Exemptions:

It’s important to note that the definition of “structure” under the BA is broader than that of “building.” Structures do not necessarily need to be fixed, enclosed by walls, or roofed. However, when an object, such as a shipping container, is determined to be a building, the building assessment provisions typically apply unless it falls under exemptions mentioned in the legislation.

Navigating the Building Approval Process:

Building approval is a vital step in ensuring that structures meet safety standards, zoning regulations, and building codes. While shipping containers offer flexibility and convenience, connecting them to power and sewerage raises specific considerations that necessitate diligent adherence to building approval processes. Let’s delve into the key aspects you need to keep in mind.

Power Connection:

When utilizing a shipping container as a dwelling or office, connecting it to a power supply becomes essential. However, this connection can have implications for building approval. Local regulations may require specific permits and inspections to ensure compliance with electrical safety standards. It is crucial to engage qualified professionals to handle power connections and seek necessary approvals to ensure the safety and legality of your setup.

Sewerage System:

Proper sanitation and wastewater management are vital for shipping containers used as dwellings or offices. Connecting these structures to an appropriate sewerage system requires careful planning and adherence to building regulations. Depending on local requirements, you may need to obtain permits and ensure that the system meets health and safety standards. Consulting with experts in plumbing and sanitation can help navigate the approval process and ensure compliance with regulations.

Compliance with Building Codes:

Shipping containers used for habitation or commercial purposes must adhere to relevant building codes. These codes encompass various aspects, including structural integrity, fire safety, ventilation, insulation, and accessibility. Modifications made to shipping containers, such as adding windows, doors, or partitions, need to meet the requirements set forth in building codes. Working with qualified architects and engineers can help ensure compliance and streamline the building approval process.

Safety Considerations:

In addition to power and sewerage connections, safety remains paramount when repurposing shipping containers. While they may offer a sturdy base, it is important to address potential hazards and implement necessary safety measures. This may include reinforced roofing, proper insulation, fire-resistant materials, and adequate ventilation. Compliance with safety standards is a critical component of the building approval process and ensures the well-being of occupants.

Considerations for Cyclone-prone regions

In cyclonic regions, repurposing a shipping container into a liveable structure requires careful attention to structural reinforcement, cyclone-resistant design principles, and compliance with building codes. While shipping containers possess inherent strength, they may not withstand the extreme forces generated during cyclonic events. Enhancing their resistance through additional supports, bracing, and reinforcing components is essential. Incorporating features like reinforced roofing, impact-resistant windows, secure foundations, and effective stormwater drainage systems aligns with cyclone-resistant design principles. It is advisable to engage architects or engineers experienced in cyclone-prone areas to ensure compliance with local building regulations and safety standards. Meeting the specific requirements for wind load resistance, structural integrity, and safety measures outlined in cyclonic region codes is crucial. Collaborating with professionals familiar with these codes helps ensure compliance and prioritize safety.


To determine if building approval is required for a shipping container used as a dwelling, offices, or storage, a thorough analysis of the specific case is necessary. Factors such as permanency, intended use, size, and utility connections play a crucial role. Based on interpretation and case law, shipping containers placed on land for ongoing use generally fall within the definition of a building, requiring compliance with building assessment provisions and potentially building approval. It’s essential to consult with building certifiers to ensure compliance with relevant building regulations. Understanding the interpretation of legislation and the context-specific analysis of permanency and usage will help determine whether building approval is necessary. By adhering to the applicable requirements, you can ensure the safety, compliance, and legality of your shipping container structure.
