When you search for granny flat builders near me, distance is one factor, but it is not the one that protects you. What matters most is whether a builder is registered, insured, clear about what is in the price and familiar with the rules in your council area. This guide walks you through the checks to make before you sign, the questions to ask and how location fits into the decision.
Key takeaways
- Check that any builder is registered with the Building and Plumbing Commission (BPC) before you sign.
- Home Warranty insurance applies to eligible new domestic building work valued at more than $20,000 from 1 July 2026.
- A major domestic building contract is required for work worth more than $10,000.
- Compare full inclusion lists, warranties and timelines, not just the headline price.
- Local knowledge of councils, overlays and site conditions matters more than how close the office is.
What to look for in granny flat builders near me
Most people type granny flat builders near me because they want someone who knows their area and is easy to reach. That is a sensible starting point. In practice, “near” is less about kilometres and more about:
- knowing the planning controls and overlays that apply in your council
- understanding local soil, slope and drainage conditions
- being able to visit your site for an assessment and during construction
- responding clearly when you have questions
A builder who works across Melbourne can tick all of these boxes, and so can one based in your suburb. Either way, you want the same protections: registration, insurance, a clear contract and a warranty you understand. The checks below help you compare any builder on the same terms.
Step 1: Check the builder’s registration
In Victoria, practitioners must be registered with the Building and Plumbing Commission to carry out domestic building work worth more than $10,000, with some trades exempt. The BPC took over this role from the Victorian Building Authority, so older links to the VBA register may now redirect to the BPC.
Use the BPC’s check licence and registration tool to confirm:
- the builder or company name matches the one on your quote and contract
- the registration is current
- the registration class covers the work you need
Ask for the registration number early. A reputable builder will be happy to provide it.
Step 2: Confirm the insurance
Insurance protects you if something goes wrong with the builder or the work.
From 1 July 2026, Victoria moved from Domestic Building Insurance to Home Warranty insurance for new eligible domestic building work. According to the BPC, Home Warranty applies to work valued at more than $20,000 and can provide up to $400,000 in total per home, subject to eligibility, limits and exclusions. It may apply where work is incomplete, defective or non-compliant and the builder fails or refuses to fix it.
Work under contracts signed before that date may still be covered by Domestic Building Insurance, if a certificate was issued before 1 July 2026. The BPC page on Domestic Building Insurance and Home Warranty explains which scheme applies.
When you speak to granny flat builders near me, ask:
- Will my build be covered by Home Warranty insurance?
- When will I receive the certificate?
- Do you also carry public liability insurance?
Step 3: Read the contract carefully
A major domestic building contract is required for domestic building work worth more than $10,000. A granny flat build will be well above that, so expect a written contract that sets out the work, the price and the payment stages.
Before you sign, check:
- the full scope of work and the plans it refers to
- the contract price and what could change it
- the payment schedule and what each stage covers
- the expected timeline from planning to handover
- how variations are requested, priced and approved in writing
- what happens if site conditions differ from what was assessed
If anything is unclear, ask the builder to explain it in writing. You can also ask an independent adviser to review the contract before you sign. Read mistakes to avoid when building a second dwelling for common traps.
Step 4: Compare inclusions line by line
Two quotes can look similar at the top and be very different underneath. When you compare granny flat builders near me, ask each one for a full inclusion list and check items such as:
| Item | What to ask |
|---|---|
| Building permit and reports | Are the permit, plans, soil test and energy rating included? |
| Service connections | How far do water, sewer and power connections run from the main house? |
| Footings | Is it a slab or a stumps and subfloor system, and does it suit my soil? |
| Kitchen | What benchtop thickness, cabinetry and appliance brands are included? |
| Flooring | What type and thickness of flooring is included? |
| Windows | Are the windows double-glazed? |
| Heating and cooling | Is a split system included, and what size? |
| Bathroom | What shower screen and vanity are included? |
| Decking | Is there a landing or deck, and how big? |
| Exclusions | What is not included, such as landscaping or driveways? |
If an item is not listed, ask before you sign. Our guide to granny flat inclusions in Melbourne explains what each item means, and fixed price granny flats in Victoria covers why a clear price matters.
Step 5: Understand the warranty
Victorian law implies certain warranties into domestic building contracts, and Home Warranty insurance sits on top of that. Beyond the legal requirements, ask each builder:
- What structural warranty do you provide, and for how long?
- Is there a maintenance period after handover?
- How do I report a defect, and how quickly will someone respond?
- Who looks after warranty work once the build is finished?
Get the answers in writing. A clear warranty process matters for years after you move in.
Step 6: Ask for references and see finished work
Photos are a start, but seeing a finished granny flat in person tells you far more about a builder’s workmanship. Ask whether you can:
- visit a display home
- see a completed project, with the owner’s permission
- speak with recent clients about communication, timelines and how issues were handled
When you read online reviews, look for patterns across many reviews rather than focusing on one comment. Our guide to visiting a display granny flat explains what to look at.
Step 7: Check their knowledge of your council
This is where local knowledge earns its place. In Victoria, a small second dwelling of up to 80m² does not need a planning permit in most residential zones. Lots under 300m² and some overlays, such as heritage, bushfire or flood, may need one, and a building permit is always required. From 15 October 2026, the maximum size of a small second dwelling increased from 60m² to 80m² under Amendment VC306. Read our guide to the 80m2 granny flat rules in Victoria (link to https://innovistagroup.com.au/80m2-granny-flat-victoria/).
A builder who knows your area should be able to talk you through:
- whether your lot size or any overlay triggers a planning permit
- setbacks and siting requirements for your block
- easements and restrictive covenants on your title
- tree protection controls in your council
- access for machinery and materials
Our guides to granny flat approvals in Victoria, council requirements by suburb and setback requirements go into more detail. If you are unsure, check with your council.
Step 8: Ask about the site assessment
A site assessment is where a builder confirms what your block needs. It should look at access, slope, soil, services, overlays and where the granny flat will sit. Ask:
- Is the site assessment free?
- Will I get the outcome and any site costs in writing before I commit?
- What could change the price after the assessment?
Read why your free site assessment matters and what makes a block suitable for a granny flat to prepare.
Questions to ask granny flat builders near me
Bring this list to every meeting so you can compare answers side by side:
- What is your BPC registration number?
- Will my build be covered by Home Warranty insurance, and when will I get the certificate?
- What is included in the price, and what is excluded?
- How far do service connections run, and what if mine run further?
- Is the building permit included, along with all plans and reports?
- How long will the build take from planning to handover?
- Who will be my main contact, and how often will I hear from you?
- What structural warranty and maintenance period do you offer?
- Can I see a finished granny flat or display home?
- Does my block need a planning permit?
When distance does matter
Location can still play a part. A builder who regularly works in your area may already know local council processes, common soil types and access issues. Distance can also matter for site visits during construction and for warranty call-outs after handover.
The practical question is not “how close is your office?” but “how often do you build in my area, and how will you look after my project?” Ask any builder which suburbs they cover and how they manage site visits.
Some homeowners also prefer to meet in person. If that is you, ask whether you can visit a display or meet at your site.
How Innovista approaches your build
Innovista builds the G-Flat™, a 60m² two bedroom turnkey home with five floor plans and five finish levels. All plans cost the same within a finish level.
| Finish level | Turnkey price |
|---|---|
| Affordable Lite | $195,000 |
| Affordable | $208,000 |
| Homestead | $218,000 |
| Signature | $238,000 |
| Luxe | $265,000 |
Prices are a guide for a standard 60m², two bedroom G-Flat™ and depend on your site. Sites 70km or more from the Melbourne CBD attract a 12.5% regional surcharge, sites with no driveway or tight backyard access attract a $7,000 surcharge, and sloping or elevated sites can affect the final price. A free site assessment confirms the price for your block.
Every G-Flat™ includes:
- the building permit and all required reports
- all plans
- connection of services up to 10m from the main house
- stone benchtops and soft-close cabinetry
- Hybrid SPC or laminate flooring, depending on the finish level
- double-glazed aluminium windows
- a reverse cycle split system
- a 10-year structural warranty and a 6-month maintenance guarantee
A G-Flat™ takes approximately 5 months end to end, from planning to handover. See our complete guide to granny flats in Melbourne for more on the process.
