Renting out granny flats in Melbourne comes with specific legal obligations. Victoria’s rental laws have evolved significantly, with new standards taking effect throughout 2025. Understanding what you must provide protects you from penalties and keeps your investment compliant. Whether you’re a first-time landlord or experienced investor, staying current with rental requirements matters. Let’s break down what landlords must provide when renting granny flats in Melbourne.
Minimum Standards for All Rental Properties
Victoria’s rental minimum standards apply to all rental properties, including granny flats in Melbourne. These aren’t optional. They’re legal requirements that every landlord must meet before advertising a property.
Essential standards include:
- Working smoke alarms on each storey
- Adequate heating in main living areas
- Safe electrical systems and installations
- Secure locks on external doors and windows
- Weatherproofing to prevent water penetration
- Proper drainage and guttering
Granny flats must meet these standards whether you’re renting to family at reduced rates or market tenants. The rental income from granny flats depends on compliance. Non-compliant properties can’t be legally rented.
Heating Requirements
All granny flats in Melbourne must have fixed heating in the main living area. The heater must be capable of heating the space to 20 degrees Celsius. Portable heaters don’t satisfy this requirement.
Acceptable heating options include:
- Fixed gas heaters with proper ventilation
- Reverse-cycle air conditioning systems
- Electric panel heaters permanently installed
- Hydronic heating systems
The heating requirement applies from 1 December 2024 onwards. If you’re building a new granny flat for rental income, include compliant heating from the start. Retrofitting heating later costs more than installing it during construction.
At Innovista, our packages include heating systems that meet rental standards as part of the build.
Smoke Alarm Compliance
From November 2025, all rental properties must have annual smoke alarm safety checks. This applies to granny flats in Melbourne regardless of when your rental agreement started.
Smoke alarm requirements include:
- Hard-wired smoke alarms on each storey
- Interconnected alarms if property has multiple levels
- Annual professional testing and maintenance
- Documentation of all testing completed
You’re responsible for organising and paying for annual smoke alarm checks. Tenants must allow access for these inspections. Keep records of all testing and maintenance. These protect you if questions arise about compliance.
Window Covering Safety Standards
From 1 December 2025, all corded internal window coverings must have safety devices fitted. This prevents strangulation hazards, particularly for young children.
You must either:
- Install safety devices on existing corded blinds
- Replace corded blinds with cordless alternatives
- Fit motorised window treatments
This requirement applies to all granny flats rented in Melbourne. Budget for compliance before the December deadline. Costs vary depending on whether you retrofit safety devices or replace window treatments entirely.
Security Requirements
Rental properties must have adequate security measures. For granny flats in Melbourne, this means:
- Deadlocks on all external doors
- Window locks on all accessible windows
- Secure door frames that can’t be easily forced
- Adequate external lighting near entry points
These requirements apply whether your granny flat is new or existing. Check that all locks work properly and keys are provided to tenants. Security matters for tenant safety and affects rental income from granny flats through tenant attraction.

Kitchen and Bathroom Essentials
Granny flats must be self-contained with proper kitchen and bathroom facilities. This isn’t negotiable for rental properties in Victoria.
Kitchen requirements include:
- Adequate food preparation space
- Cooking facilities (stove or cooktop)
- Kitchen sink with hot and cold water
- Reasonable storage for food and utensils
Bathroom requirements include:
- Toilet in good working order
- Shower or bath with hot water
- Basin with hot and cold water
- Adequate ventilation (window or exhaust fan)
These seem basic, but inspectors check them carefully. All fixtures must work properly. Water pressure must be adequate. Drainage must function correctly.
Energy Efficiency Standards
New granny flats in Melbourne must achieve minimum 7-star energy ratings. This became mandatory in 2023 and applies to all new construction.
If you’re building for rental income from granny flats, this affects your construction specifications:
- Proper ceiling and wall insulation
- Energy-efficient windows and doors
- Sealed construction preventing draughts
- Compliant heating and cooling systems
Existing granny flats built before these standards don’t need retrofitting immediately. However, higher energy efficiency attracts better tenants and justifies higher rents. Consider upgrades even if not legally required.

Maintenance and Repairs
Landlords must maintain granny flats in good repair throughout tenancies. This includes:
- Fixing plumbing leaks promptly
- Repairing electrical faults immediately
- Addressing heating or cooling failures quickly
- Maintaining gardens and lawns if specified in lease
- Keeping gutters clear and drainage working
You’re responsible for structural maintenance and major repairs. Tenants handle minor issues like changing light bulbs. Clear communication about maintenance responsibilities prevents disputes.
Prompt maintenance protects your investment and keeps tenants satisfied. Happy tenants stay longer, reducing vacancy periods and maximising rental income from granny flats.
What You Can’t Do
Understanding restrictions matters as much as knowing requirements. Victorian rental laws limit landlord actions.
You cannot:
- Enter the property without proper notice (except emergencies)
- Increase rent more than once every 12 months
- Evict tenants without proper legal grounds
- Refuse reasonable requests for modifications
- Discriminate against tenants with children or pets
These protections apply to granny flats in Melbourne just like any rental property. Violating them creates legal problems and potential penalties.
Documentation and Record Keeping
Keep thorough records of all compliance measures:
- Smoke alarm testing certificates
- Heating system installation and service records
- Safety device installation for window coverings
- Maintenance and repair receipts
- Inspection reports and photographs
Good documentation protects you if compliance questions arise. It also demonstrates professional property management to authorities and tenants.
