But before you start drawing up floor plans or calling builders, there's one critical step that many homeowners skip: running a title search on your property.
A title search reveals essential information about your land that directly impacts whether you can build a granny flat — and what restrictions might apply. Skipping this step can lead to costly surprises, council rejections, and even legal disputes.
In this comprehensive guide, we'll walk you through everything you need to know about title searches for granny flats in Queensland.
What is a Secondary Dwelling (Granny Flat) in Queensland?
Under Queensland planning legislation, a secondary dwelling is a self-contained dwelling built on the same lot as a primary dwelling. These are commonly called granny flats, but they can serve many purposes:
- Elderly parent accommodation — keeping family close while maintaining independence
- Rental income — generating passive income from your existing property
- Home office or studio — a separate workspace away from the main house
- Teen retreat — providing older children with their own space
- Guest accommodation — hosting visitors in comfort and privacy
Queensland's Granny Flat Rules at a Glance
| Requirement | Detail |
|---|---|
| Maximum floor area | 80m² (some councils may vary) |
| Must be on same lot | Cannot be on a separate title |
| Self-contained | Kitchen, bathroom, and living areas required |
| Council approval | Development application usually required |
| Minimum lot size | Varies by council (typically 450m²–600m²) |
| Cannot be sold separately | Must remain part of the same property |
Important: Rules vary between Queensland councils. What's permitted in Brisbane City Council may differ from Moreton Bay or Logan. Always check your local planning scheme — but first, check your title.
Why You MUST Run a Title Search Before Building a Granny Flat
A title search is not just a bureaucratic formality — it's your first line of defence against expensive mistakes. Here's exactly what a title search reveals that matters for granny flat construction:
1. Easements That Could Block Construction
Easements are rights granted to other parties to use part of your land. Common easements include:
- Drainage easements — allowing water infrastructure to cross your property
- Access easements — granting neighbours or utilities right of passage
- Sewerage easements — protecting underground sewerage lines
- Electricity easements — protecting overhead or underground power lines
Why it matters: You generally cannot build any structure — including a granny flat — within an easement area. If your preferred building location sits on an easement, you'll need to redesign or apply for an easement relocation (which can cost thousands).
2. Covenants and Building Restrictions
Some properties have restrictive covenants registered on the title. These are legally binding conditions that may:
- Prohibit secondary dwellings entirely
- Restrict building materials or design styles
- Limit the number of dwellings on a lot
- Set minimum setback distances beyond council requirements
Covenants are particularly common in newer housing estates and master-planned communities. A title search is the only reliable way to discover them.
3. Lot Size and Boundaries
Your title search confirms the exact lot size and plan number of your property. This is critical because:
- Council minimum lot sizes for secondary dwellings vary
- Your actual lot size may differ from what the real estate agent told you
- Boundary locations affect setback calculations
- Irregularly shaped lots may have less usable building area than expected
4. Existing Encumbrances
Your title may reveal other encumbrances such as:
- Mortgages — your lender may need to approve secondary dwelling construction
- Caveats — third-party claims that could prevent development
- Statutory charges — unpaid rates or other government charges
- Leases — existing lease arrangements that affect the property
Step-by-Step: How to Use Your Title Search for Granny Flat Planning
Step 1: Order Your Title Search
The fastest way to get your Queensland title search is through an online service. You'll receive a current title search document that shows all registered interests on your property.
Step 2: Check for Easements
Look at the Easements section of your title. If any easements are listed, obtain the associated survey plan to see exactly where they fall on your property. Map these against your proposed granny flat location.
Step 3: Review Covenants
Check the Dealings section for any registered covenants. If covenants exist, obtain the covenant document to read the specific restrictions. Pay particular attention to any clauses about:
- Number of dwellings permitted
- Building height restrictions
- Minimum lot coverage requirements
Step 4: Confirm Your Lot Details
Note down your: - Lot number - Plan number (RP, SP, or BUP) - Total lot area - Title reference number
You'll need all of these when lodging your development application with council.
Step 5: Check with Your Lender
If your title shows a registered mortgage, contact your lender. Most banks require notification — and sometimes formal approval — before you build a secondary dwelling on a mortgaged property.
What Happens If You Build Without Checking the Title?
We've seen homeowners face serious consequences from skipping the title search step:
| Scenario | Potential Cost |
|---|---|
| Building on an easement | $20,000–$50,000+ to demolish or relocate |
| Breaching a covenant | Legal action from covenant beneficiary |
| Building on wrong boundary | Survey dispute + rebuilding costs |
| Council rejection due to lot size | Wasted architectural fees ($5,000–$15,000) |
| Lender refusal | Potential breach of mortgage conditions |
A title search costs a fraction of these amounts and takes just minutes to order online. It's the cheapest insurance you can buy.
Granny Flat Title Searches: Regional Considerations
Queensland's diverse geography means granny flat rules and title considerations vary by region:
South East Queensland (Brisbane, Gold Coast, Sunshine Coast)
- Higher density areas may have stricter setback requirements
- Flood mapping overlays are common — check council flood maps alongside your title
- Strata-titled properties (units, townhouses) generally cannot add secondary dwellings
Regional Queensland (Toowoomba, Hervey Bay, Bundaberg)
- Larger lot sizes often provide more flexibility
- Rural-zoned properties may have different secondary dwelling provisions
- Check for agricultural easements or vegetation management covenants
North Queensland (Cairns, Townsville, Mackay)
- Cyclone-rated construction requirements increase building costs
- Some titles include specific environmental covenants
- Indigenous land considerations may apply in certain areas
Frequently Asked Questions
Can I build a granny flat on any property in Queensland?
Not necessarily. Your property must meet minimum lot size requirements (varies by council), comply with any registered covenants, avoid easement areas, and be appropriately zoned. A title search is the first step to determining eligibility.
Do I need a title search if I already know my property details?
Yes. Title information changes over time. New easements may be registered, caveats may be lodged, or covenants may apply that weren't present when you purchased. Always order a current title search before commencing any development.
How long does a title search take?
When you order online through TitleFinder, you'll typically receive your title search results within minutes — delivered straight to your email.
Can I rent out my granny flat in Queensland?
Yes, in most cases secondary dwellings can be rented out. However, your title may contain covenants that restrict rental activity — another reason to check the title first. Additionally, some council planning schemes have specific rules about renting secondary dwellings.
What's the difference between a granny flat and a duplex?
A granny flat (secondary dwelling) must be on the same title as the primary dwelling and cannot be sold separately. A duplex can be on separate titles and sold independently. If you're planning a duplex, you'll need a different development pathway and potentially a subdivision title search.
Do I need council approval for a granny flat in QLD?
In most cases, yes. Queensland councils typically require a development application for secondary dwellings. Your title search provides the lot and plan details needed for this application, plus reveals any constraints council will consider.
