Victoria’s granny flat revolution is delivering serious profits for investors who understand the compliance landscape. As of 2026, granny flat Victoria regulations have been transformed through the Victorian Housing Statement, removing dependent-use restrictions and creating unlimited rental income potential. Properties are now generating rental yields as high as 12% when built and managed correctly.
This guide breaks down Victoria’s current compliance requirements and profit opportunities for families and investors building secondary dwellings in 2026.
Victoria’s Regulatory Framework: What Changed In 2023-2026
The Victorian Government’s Housing Statement transformed the granny flat Victoria landscape. Following Amendment VC253 in December 2023, small second homes up to 60 square metres no longer require planning permits in most cases where there are no flooding, environmental, or other special planning controls.
This regulatory shift represents the biggest investment opportunity in Victorian property in years. Smart investors are capitalising on streamlined approvals whilst rental markets reach crisis-level tightness with Melbourne’s vacancy rate consistently under 1.5%.
Key 2026 Victorian Regulations
No planning permits required when:
- Property is 300m² or larger
- Granny flat is 60m² or smaller
- No heritage, bushfire, or environmental overlays apply
- Meets standard setback requirements (1m side, 4m rear)
Always required:
- Building permits through registered building surveyor
- 7-star NatHERS energy rating (mandatory since October 2023)
- Compliance with National Construction Code 2022
- Residential tenancy standards
Prohibited:
- Natural gas connections (banned under Victoria’s Gas Substitution Roadmap)
- Subdivision or separate sale from main dwelling
The transitional period for old Dependent Person’s Units was extended by Amendment VC266 to expire on 28 March 2026, giving existing builds time to adapt.
Compliance Requirements: Building Permits And Standards
Understanding granny flat Victoria compliance requirements separates profitable investments from expensive mistakes. In most cases, planning permits aren’t needed, however building permits are always required.

- Structural integrity and foundation engineering

Council-Specific Variations
Different Victorian councils interpret requirements differently:
Inner Melbourne councils (Yarra, Port Phillip, Stonnington):
- Often have heritage overlays requiring planning permits
- Stricter design standards
- Longer approval times (10-14 weeks)
Outer Melbourne councils (Casey, Cardinia, Wyndham):

Professional consultation prevents expensive redesigns and compliance issues.

Site Assessment: Determining Suitability
Professional site assessment determines feasibility and compliance costs before construction begins. Victorian soil conditions, climate factors, and council variations significantly impact build costs and approval timeframes.
Essential Site Evaluation
Lot requirements:
- Minimum 300m² for planning permit exemption
- Check Certificate of Title for easements
- Verify services within 15m (water, sewer, power)
- Confirm vehicle access for construction
Overlay checks:
- Heritage Overlay: Planning permit required, adds $5,000-$10,000 and 8-12 weeks
- Bushfire Management Overlay: Enhanced construction standards, adds 10-15% to costs
- Flood Overlay: Elevated floors required, adds $8,000-$15,000
- Environmental Significance: Specialist assessments needed
Soil conditions:
- Western suburbs: Reactive clay soils need engineered foundations (+$8,000-$15,000)
- Coastal areas: Sandy soils require different structural solutions
- Sloping blocks: Retaining walls and cut/fill (+$10,000-$30,000)
Understanding these factors before purchase prevents expensive surprises.
