A granny flat. More possibilities for your property.

Usually not, if the block qualifies. Since Amendment VC306 (operative 15 October 2026) a small second dwelling of up to 80 m² total floor area (Clause 73.03; 60 m² under VC253) needs no planning permit in the main residential zones on a lot of 300 m² or more, provided there is no more than one existing dwelling, it is the only small second dwelling, it has no reticulated gas, and no overlay or title restriction says otherwise. A lot under 300 m² still needs a permit. A building permit is always required, and the Building Regulations 2018 still define a small second dwelling as ≤ 60 m², so confirm the building pathway for a 60–80 m² design with a building surveyor.

In the main residential zones a lot under 300 m² still needs a planning permit for a small second dwelling (e.g. Clause 32.08-6). A lot of 300 m² or more removes that trigger only: overlays, other zone conditions and title restrictions still need checking, and a measured layout must show the dwelling (up to 80 m² under VC306) fits with its setbacks, access and services. The 550–600 m² figure in our buying strategy is a commercial screening preference, not a legal minimum.

The shared price book updated 2026-10-17 lists the 34 m² home at $121,000 and the 60 m² home at $170,500 in Victoria, including GST. Compare all six current offers and each published VIC, QLD, NSW and WA price in the table on this page. These are building-product prices, not a complete acquisition or site budget. Confirm the actual property's scope, approvals, site works, services and exclusions in writing. Maintained source: https://e2es.com.au/granny-flat-cost#state-prices

A return calculated on construction spend alone is not the whole-property rental yield: it leaves out the land and existing house. Across the 212 granny-flat additions in our historical dataset, the median whole-property gross yield after works was 5.79%, against 5.16% for cosmetic renovation only (345 purchases settled January 2023 to September 2025). These are historical outcomes, not a forecast. Current build quotes and a property-specific rental appraisal are separate inputs.

This is a historical worked example, not a current quote or rent forecast. It is an annualised cash-on-cash return on the cash actually put in, and every input behind it is disclosed on this page: a 60 m² build at $155,000 + GST, an 80% construction loan against the build contract at 6.5% interest-only, $500 a week rent, and $42,200 of cash in. It is gross and pre-tax: council rates, insurance, management fees and vacancy are not deducted. It is not a property yield and it should never be compared against one — a property yield divides by the land and the house as well. Measured that way, our published median is 5.79%.

The building team’s published programme is four weeks of paperwork followed by three months of construction. Scope, access, approvals, start dates and the schedule are agreed before signing. A programme is not permission to build, and timing for a particular property must be confirmed in writing.

Building classification, engineering, valuation and lending approval are separate decisions. Confirm the classification and approved design for the selected home; a rooming house has different requirements from a small second dwelling. The lender and valuer assess the actual project independently. PremiumREA holds no Australian Credit Licence and does not recommend lenders or promise an as-if-built valuation or an amount of releasable equity.

Not while a limited recourse borrowing arrangement is on foot. The ATO’s position (SMSFR 2012/1) is that adding a second dwelling changes the character of the acquirable asset, which the borrowing rules do not permit — so a fund with a loan outstanding is generally restricted to move-in-ready stock. That is a property constraint we can describe; whether to buy through a fund at all is a question for a licensed financial adviser and a registered tax agent, and PremiumRea holds no Australian Financial Services Licence.

Yes. Start with the native address form on this page: choose the matching address, review the options for that state and request the assessment results by email. Victoria also has an indicative planning screen. For Western Australia, when the source and site checks clear, results and available PDFs are emailed automatically. Many WA sites currently need a team review first; either way, we email you the outcome. The separate Site Planner remains available for geometric research. Preliminary results are not approval, a working drawing or a guarantee that a design can be built.

The current compact home uses the 34 m² product category. Its Fernwood drawing measures 34.3 m² and has one separate bedroom and one bathroom, with a 2.4 m ceiling. Older “30” asset names are legacy references.

Yes. The 60 m² drawings offer two or three bedrooms, one bathroom and 2.4 m ceilings. The standard 80 m² and Premium drawings offer two or three bedrooms, two bathrooms and 2.7 m ceilings. The supplied enclosed-garage drawing has two bedrooms and two bathrooms.

It is a previously built design with nine bedrooms, nine ensuites and 2.4 m ceilings. The supplied drawing records 292.05 m² including the porch; “300 m²” is its nominal category. Planning use, classification, fire safety, accessibility and operating requirements still need project-specific confirmation.

No. A state price and a floor plan do not establish site approval. Check the title, boundaries, easements, covenants, zone, overlays, access, services and the relevant approval pathway. Preliminary feasibility supports the next design stage; it is not a working drawing or permit.
