What Are the New Granny Flat Rules in Victoria?

Victoria’s recent government changes, initially announced in December 2023 and fully confirmed and effective as of March 2026, have fundamentally changed the outlook for building granny flats. Homeowners can now construct a ‘small second home’ (the official planning term for a secondary dwelling or granny flat) up to 60 square metres on their property without needing a planning permit, provided it adheres to specific conditions. This marks a significant shift from previous regulations, which were often restrictive and complex.

Previously, granny flats in Victoria were typically subject to extensive planning permit processes, and their occupation was limited to dependants or family members. The new reforms simplify this by removing the planning permit hurdle for qualifying dwellings and, most importantly, enabling these secondary homes to be rented out to anyone, not just family. This brings Victoria in line with other states like New South Wales and Queensland, which have long had more permissive granny flat regulations.

How Do These New Rules Simplify Approvals for Victorian Homeowners?

The new Victorian granny flat rules substantially simplify the approval process by largely removing the need for a planning permit in most residential zones. This eliminates a major administrative and time-consuming step for many homeowners. Instead of dealing with the complex and often lengthy planning permit applications with local councils, homeowners will primarily focus on obtaining a building permit.

A building permit, issued by a private building surveyor or local council, ensures that your proposed granny flat meets essential safety, structural, and amenity standards outlined in the National Construction Code (NCC) and other Victorian building regulations. While a building permit is still mandatory, it is generally a more straightforward process than a planning permit. Our site’s Approval Pathway Finder can help you understand whether your specific granny flat project qualifies for this fast-track approach or if any unique site conditions might still require additional council engagement.

This freedom to rent out your secondary dwelling opens up new financial opportunities for homeowners.
