Building permits are required for most structural alterations, additions, and new construction work in Victoria, ensuring compliance with the National Construction Code and local regulations. Costs vary significantly depending on the scope and complexity of the project.
As of December 2025, permit costs are calculated based on the estimated cost of building works. The Victorian Building Authority (VBA) uses a tiered fee structure. For smaller renovations, such as a deck or minor bathroom update, permit fees currently in Melbourne can range from approximately $150 to $500. More substantial projects, common in the Eastern Suburbs where we see many renovations to family homes – like extensions or structural changes – can attract fees between $800 and $3,000 or more. It’s important to realise that these figures don’t include associated costs like building surveyors’ fees (typically $800 – $2,500+ depending on complexity) which are also required. In 2026, sellers undertaking renovations to maximise their property’s appeal should factor these costs into their overall budget. We often advise clients preparing to sell that having approved permits readily available can favour a smoother sales process, demonstrating due diligence to potential buyers. The VBA website provides a fee calculator to help estimate costs, but a professional assessment is always recommended.
Understanding building permit costs is a key component of responsible property ownership and can impact renovation budgets, particularly when preparing a home for sale.
