Granny Flat Victoria: 2026 Guide 🏡

Victoria changed its granny flat laws in late 2023 to help ease the housing shortage. The government now officially calls these units Small Second Dwellings. Most homeowners can build one without a planning permit, rent it to anyone, and add real value to their block. 📈
This guide covers the full picture of granny flats in Victoria: the basic rules, rental options, costs, design, and investment potential. Each section links to a detailed guide if you want to go deeper. 📑

What Are the Basic Rules for a Granny Flat Victoria? 📐

Your unit must stay under 60m² in gross floor area. This includes any verandas or porches under the roofline. You need a kitchen, a bathroom, and a toilet inside the unit itself to make it fully self-contained. 🚿

Most homeowners on blocks over 300m² don’t need a planning permit. You still need a Building Permit, though — a registered surveyor checks your plans against Victoria’s ResCode rules and National Construction Code (NCC) standards before you build. 🏗️

There are a few hard limits, too:

🚫 No Subdivision: You can’t subdivide your land to sell the unit separately.
🚫 No Gas Connections: Under Victoria’s gas-transition policy, new Small Second Dwellings cannot be connected to reticulated natural gas (all-electric only). 🔌
🚧 Easements: You can’t build over council pipes or drains without prior approval.

Always check your property title for covenants or Section 173 agreements before you start. 🔍

Can I Rent Out My Granny Flat in Victoria? 🔑

What Design Options Work Best for a 60m² Granny Flat? 💡

Smart design makes a small footprint feel much larger. High ceilings and north-facing windows are the two biggest wins for bringing in natural light and warmth. ☀️

Design Tip: An outdoor deck adds beautiful living space — and because it sits outside the roofline, it does not count toward your 60m² gross floor area limit! 🪵
