Starting your granny flat investment in Victoria? Smart move. But rushing in without proper planning is the fastest way to lose money.
Most successful investors spend weeks preparing before they even talk to builders. There’s a good reason for that. Getting the groundwork right saves you thousands of dollars, months of delays, and plenty of stress.
Here’s your complete action plan. Follow these steps to ensure you’re ready for a profitable granny flat investment Victoria project.
Before You Call Builders: Your Essential 5-Step Checklist
Step 1: Check Your Property Title and Restrictions
Your first job is simple. Check your property title for any restrictions or covenants.
Some properties have rules about secondary dwellings. You need to know these upfront. Finding out after you’ve paid for plans is expensive and frustrating.
Where to get your property title:
- Your local council
- Victoria’s land titles office online
- Through a conveyancer
At Innovista, our site acquisition process identifies potential title issues before you commit. This saves you from costly surprises down the track.
Why this matters for your granny flat investment in Victoria: Title restrictions can completely block your project. Better to know now than after spending $5,000 on plans.

Step 2: Understand Council Requirements and Setbacks
Every Victorian council has different rules. Where you can put granny flats varies. How big they can be varies too.
Key council requirements:
- Setback distances from boundaries
- Setback distances from your main house
- Maximum building coverage
- Height restrictions
- Parking requirements
Some councils are easy to work with. Others aren’t. Knowing this upfront helps you plan properly.
What are setbacks? Setbacks are the minimum distances your granny flat must be from property boundaries. Most Victorian councils require:
- 1 metre from side boundaries
- 3 metres from rear boundaries
- 6 metres from front boundaries
Innovista’s permits and design consultation service handles these regulatory requirements. We navigate Victoria’s complex council frameworks to secure approvals without delays.
Pro tip for granny flat investment Victoria: Call your council before designing anything. Ask about their specific requirements. This 10-minute call saves months of hassle.

Step 3: Work Out Your Complete Budget
Don’t just budget for the build cost. That’s only part of what you’ll spend.
Add 15-20% for these extras:
- Site preparation
- Utility connections
- New driveways
- Landscaping
- Fencing adjustments
Then factor in your ongoing costs:
- Loan repayments
- Insurance
- Council rates
- Maintenance
- Property management fees
Many investors forget these costs. They end up with nasty cash flow surprises.
Real budget example for granny flat investment in Victoria:
- Build cost: $210,000
- Soil tests: $1,200
- Engineering reports: $2,500
- Council fees: $2,000
- Building permit: $2,000
- Landscaping: $5,000
- Driveway extension: $8,000
- Total project cost: $230,700
Our feasibility studies provide comprehensive assessments. You’ll know exactly where every dollar goes.
Budget smartly: Always have a 10% buffer. Unexpected costs always appear. Being prepared keeps your granny flat investment Victoria on track.

Step 4: Research Real Rental Returns in Your Area
You need realistic rental figures. Don’t rely on general Melbourne averages.
How to research rental returns:
- Check Domain and realestate.com.au weekly
- Drive around your suburb looking at rentals
- Talk to local real estate agents
- Ask about granny flat demand specifically
- Note rental prices for similar properties
Different suburbs vary enormously. Properties in Frankston might rent for $400 weekly. Similar properties in Glen Waverley could fetch $550 weekly.
What affects granny flat rental income in Victoria:
- Proximity to public transport
- Distance to employment hubs
- School zones
- Shopping centres nearby
- Overall suburb appeal
Our market knowledge helps identify strong locations. We focus on areas where rental demand stays strong year-round. This maximises your granny flat investment Victoria returns.
Realistic rental expectations:
- Inner suburbs: $500-$650 per week
- Middle suburbs: $400-$550 per week
- Outer suburbs: $350-$500 per week

Step 5: Get Your Finances Sorted First
Know exactly how much you can borrow. Know what deposit you need. Get pre-approval if possible.
Why this matters: Builders take you seriously when you have finance sorted. You’re not just someone having a look. You’re a genuine buyer.
Benefits of pre-approval:
- Better negotiating power
- Secure your preferred timeline
- Lock in interest rates
- Speed up the entire process
- Reduce stress during construction
What to ask your finance broker:
- How much rental income counts towards borrowing capacity?
- Which lenders prefer granny flat investments?
- What are construction loan processes?
- Should I consider interest-only payments?
- Can I use an offset account?
Get these answers before starting your granny flat investment in Victoria. Proper financing makes everything easier.
How to Evaluate if Your Property is Investment-Ready
Size and Space Requirements
Your block needs room for several things:
- The granny flat building
- Required garden space
- Parking areas
- Council setbacks
Minimum requirements: Most Victorian councils need at least 300-400 square metres total. However, this varies significantly between areas.
It’s not just about total size. Usable space matters. Where utilities are located makes a big difference to costs.
Innovista’s property assessment determines suitability. We identify the best positioning for maximum rental appeal. Everything meets council requirements.
Quick size check: Measure your backyard. Subtract setback areas. What’s left is your buildable space. Need at least 80-100 square metres for a standard granny flat.
Access and Construction Logistics
Think about access carefully. Construction vehicles need to reach your building site. Future tenants need easy access to parking and entrances.
Access issues that increase costs:
- Narrow driveways (under 3 metres wide)
- No rear access to property
- Steep driveways
- Overhead power lines
- Tight corners for trucks
Poor tenant access affects rental demand. Tenants want convenient parking. They want private entrances. They don’t want to walk through your garden every day.
Our construction team factors in site logistics. We manage everything from crane access to material delivery. This keeps costs under control for your granny flat investment Victoria.
Site Conditions and Risk Factors
Check three critical things:
- Your slope
- Drainage patterns
- Soil conditions
Steep blocks: Steep blocks can be built on. They just cost more. You might need:
- Retaining walls
- Split-level designs
- More extensive foundations
- Additional drainage
Drainage problems: Walk around your yard after heavy rain. See where water goes. Watch for:
- Pooling water
- Water running towards buildings
- Poor existing drainage
- Low-lying areas
Soil conditions: Different soils need different foundations:
- Clay soils = deeper footings
- Sandy soils = standard footings
- Rock = expensive excavation
- Fill = engineering required
Innovista’s risk management approach identifies issues early. We develop cost-effective strategies to handle them. No expensive surprises halfway through your build.
Smart Questions That’ll Save You Money

What to Ask Potential Builders
Not all builders understand investment properties. Building for rental is different from building for families.
Critical questions for builders:
- How many investment granny flats have you built?
- What’s included in your base price?
- What costs extra?
- What’s your warranty period?
- Who does the actual construction?
- What’s your average timeline?
- How do you handle variations?
- Can I see recently completed projects?
Get detailed breakdowns. Some builders quote low. Then they hit you with extras for basic items.
Innovista specialises in investment-grade construction. We understand which features maximise rental returns. We skip expensive decorations that don’t affect your bottom line.
Red flags to watch for:
- Vague pricing
- No detailed inclusions list
- Short warranties (under 6 years)
- No references available
- Pushy sales tactics
What to Ask Your Finance Broker
Your broker should understand granny flat investment Victoria specifically.
Essential finance questions:
- How much rental income will banks count?
- Which lenders prefer granny flat investments?
- What’s the construction loan process?
- Should I consider interest-only payments?
- Can offset accounts help cash flow?
- What’s the best loan structure?
- How does negative gearing work?
Good brokers explain everything clearly. They find the best loan structure for your situation. They save you money on interest over time.
Your Investment Timeline: What to Expect
