Building approval plans are detailed architectural and engineering documents that show how a proposed building will look, function, and comply with safety, structural, plumbing, and fire regulations before construction begins.



1. Identify the property's local council: The first step is to find out which local government area the property is in, as they are the authority responsible for approving building work. 
2. Visit the council's website or contact them directly: Navigate to the council's website and look for sections related to "building and planning" or "request building records". You may also be able to find contact details on the council's website or by searching online. 
3. Submit a request: You will likely need to submit a formal request, often as part of a "building records search". This request should include the property address. 
4. Pay any applicable fees: Councils charge for these searches and the provision of documents, and the costs and timeframes vary by council.
