New calculations required for cost of building works in Victoria
From 26 November 2025, Victorian builders must use a new Form 1 when applying for a building permit, and it changes how permit levies are calculated. The focus is making sure levies apply only to actual building work, not appliances or extras bundled into contracts.
The new rules require builders to clearly separate the value of “chattels” such as appliances from the cost of works. If these amounts look inaccurate, surveyors can reject permit applications. That means contracts, estimates and scope details need to be precise from the start.
Our full guide breaks down the new form, what counts as a chattel, how to calculate the correct costs, examples of compliant entries, and how to avoid rejection or delays. If you want to stay compliant and avoid costly resubmissions, this resource is essential.
