Queensland has made granny flats a lot more valuable. Following state planning reforms that took effect around 2022 to 23, homeowners can now rent their secondary dwellings to anyone on the open market, not just family members. This policy change transformed granny flats from accommodation for elderly parents into genuine income-producing investments.
What Changed?
Previously, Queensland granny flats (called "secondary dwellings") could only be occupied by:
- Family members
- Household staff
- Carers
This effectively prevented them from being used as rental investments. The state's reforms (in effect since around 2022 to 23) removed this restriction entirely.
Queensland Requirements
Unlike NSW's statewide Housing SEPP, Queensland manages granny flats through local government planning schemes. Each council has different rules, but common requirements include:
Brisbane City Council Rules
- Maximum size: 80 square metres (larger than NSW's 60sqm)
- Must share connection to sewer/water with main dwelling
- Side setback: typically 1.5m minimum
- Rear setback: 6m from rear boundary
- Can be attached or detached
Gold Coast City Plan Rules
- Maximum height: 8.5m
- Site coverage limits apply (varies by zone)
- Minimum lot size: typically 450sqm+
- Must comply with character/design provisions in some areas
Note: Unlike NSW, Queensland does not have a statewide CDC-equivalent pathway for granny flats. Approval often requires a council DA, though some councils accept compliant secondary dwellings as self-assessable/accepted development.
Approval Timeline & Costs
- DA timeline: 3 to 6 months (faster than NSW in most QLD councils)
- DA fees: $2,000 to $4,000
- Build cost: $180,000 to $250,000 (similar to NSW)
- Rental income: $300 to $500/week (Brisbane), $350 to $550/week (Gold Coast)
The Numbers
With the new rental rules, the maths can look attractive. The figures below are an illustrative example only. Actual costs, rents and yields vary by location and property:
- Build cost: $220,000 (example)
- Rent: $450/week (example)
- Gross yield: ~10.6% (illustrative example)
- Payback period: ~9 years (example)
What About Other Councils?
Beyond Brisbane and Gold Coast, rules vary:
- Sunshine Coast: Similar to Gold Coast but with stricter height limits in some zones
- Moreton Bay: Generous size allowances but density controls apply
- Logan: Secondary dwellings permitted in most residential zones
- Ipswich, Townsville, Cairns: Generally permitted but check specific zones
Because Queensland lacks a statewide SEPP, it's critical to check your specific council's planning scheme before assuming you can build.
Tax Considerations
With rentable granny flats now possible, tax treatments align with other investment properties:
- Rental income is assessable
- Interest, depreciation, and maintenance are deductible
- Capital gains tax applies on eventual sale apportionment
Speak to an accountant about trust structures or claiming depreciation on the new dwelling.
