What changed for Victoria small second dwellings in 2026
Victoria’s planning reforms treat compliant backyard units as small second dwellings (commonly called granny flats). The aim is to add housing without a full development application on every block.
The headline change: if your project fits the criteria, you skip the planning permit stage that used to add months and consultant fees. That does not mean a free pass. Structural work must still comply with the National Construction Code (NCC) through a registered building surveyor.
For context on how this compares nationally, see our guide to granny flats and council approval across Australia.

When you still need a planning permit

Building permit: what it covers
A registered building surveyor issues the building permit after reviewing plans against the NCC. That includes structure, fire separation from the main house, waterproofing, energy efficiency and accessibility where triggered.
Expect mandatory inspections at slab, frame and completion stages. You cannot legally occupy or rent the dwelling until you receive an occupancy permit or certificate of final inspection.
Setbacks and siting
Even without a planning permit, siting rules still apply. Typical expectations include minimum side and rear setbacks, height limits and separation from the primary dwelling for fire safety. Your surveyor will confirm the exact numbers for your zone and lot shape.
Services and utilities
Each dwelling needs approved connections for power, water, sewer or septic, and stormwater. A second dwelling commonly needs a separate metre or sub-metre arrangement. Read our note on separate electricity metres for granny flats when budgeting.
Rental and income use
Victoria allows small second dwellings to be rented on the open market. That makes a compliant 60 m² unit a realistic income asset, subject to landlord registration, smoke alarm rules and fair trading obligations.
Check with your mortgage lender and insurer before signing a lease. Some policies treat a new secondary dwelling differently until it is fully certified.

Frequently Asked Questions
Do I need a planning permit for a 60sqm granny flat in Victoria?
On most standard residential lots that meet size, setback and overlay rules, no planning permit is required for a small second dwelling up to 60 m². Lots with heritage, flood or bushfire overlays can still need one.
Can I rent my Victoria granny flat to tenants who are not family?
Yes. Compliant small second dwellings can be rented to anyone, provided the build is certified and you meet landlord obligations under Victorian rental law.
Is a building permit still mandatory?
Yes. Every new secondary dwelling needs a building permit and final inspection before occupation, regardless of whether planning approval was skipped.
Can I sell the granny flat separately?
No. The small second dwelling must remain on the same title as the main house. Subdivision for a separate sale is not permitted under these rules.
How long does the building permit process take?
Timelines vary by surveyor workload and plan quality. Many straightforward projects move through in a few weeks once complete documentation is lodged, but allow extra time if bushfire or energy reports are required.

How much does council approval add to your granny flat budget?
Council and certifier fees sit outside the builder quote. In NSW, a CDC pathway through a private certifier often lands between roughly $3,000 and $8,000 once survey, BASIX and Sydney Water checks are included, while a full DA can cost more because of longer consultant time and holding costs. Victoria and Queensland use different fee schedules, so treat any single number as a starting point.

What design choices affect approval speed?
Setbacks, height, floor area and tree protection overlays decide whether you stay on a fast CDC track or drop to a slower DA. Staying under common 60 sqm internal caps, keeping adequate side and rear setbacks and connecting services without major easement conflicts usually keeps the pathway simpler. If your block is sloped, flood-affected or heritage-listed, expect extra reports before council or your certifier can sign off. Use the setback checker and approval wizard against your address before you pay for custom drawings.
