Can Your Switchboard Power a Granny Flat?
Often, but not always. It depends on your supply, the space on your switchboard and what the flat will run.
Older boards with fuses or no spare room usually need upgrading first.
We check the board and supply on site, then give you a fixed price.

Queensland Rules for Granny Flats
From Queensland Government planning and tenancy guidance, and the Electrical Safety Regulation 2026.
A New Granny Flat Needs Approval
Any new granny flat needs building approval. Ask your council whether development approval is also needed, and a building certifier about other requirements.
You Can Rent It to Anyone
Since 2022, a granny flat can be rented to anyone, related or not. Older approvals with occupancy conditions may need a change application first.
Approvals and Smoke Alarms Before Renting
Owners must get all relevant approvals before renting a granny flat. The flat must also meet smoke alarm requirements.

Renting It Out
No safety switch on the power points? A landlord has 90 days from the start of a new tenancy to fit one.

Who Pays for the Power
The tenancy agreement must say how electricity is paid, for example individually metered or the tenant pays a set percentage of the bill.

Main House Has No Safety Switch?
With a few exceptions, such as emergency work, an electrician can't do installation work in a home with no safety switch on the power points unless the job includes fitting one.

What Sets the Price of Granny Flat Electrical Work
We price a granny flat once we've seen the plans, the main board and the supply. These are the things that move the number.
- Distance. A longer cable run from the main board means more cable and labour.
- Cable route. Underground, under the house or through the roof changes the work.
- Main switchboard. Old fuses or no spare room may mean an upgrade.
- Supply capacity. If the supply can't carry both homes, it may need upgrading.
- Appliances. An oven, cooktop or air con each needs a suitable circuit.
- Points and lights. The number of power points, lights and fans in the flat.
- Smoke alarms. Hardwired, interconnected alarms through the flat.

Granny Flat Electrical FAQ
Questions Gold Coast homeowners ask us before adding a granny flat.
Can my existing switchboard run a granny flat?
Often, but it depends on three things: the supply to the property, the space and protection on your main board, and what the flat will run. An oven, cooktop and air conditioner add a lot of load. Boards with ceramic fuses or no spare room usually need upgrading first. We check the board and supply on site before quoting, so you know what's needed.
Does a granny flat need its own switchboard?
Often, yes. A common setup is a sub-board in the flat, fed by a cable from the main switchboard and protected at the main board. The flat's circuits can then be switched off in the flat without going to the main house. The right setup depends on the size of the flat, the distance from the main board and the load. We work it out on site.
Does a granny flat need a separate electricity meter?
Not necessarily. A granny flat can run off the main house supply through a sub-board. If you rent it out, the Residential Tenancies Authority says the tenancy agreement must state how electricity is paid, for example individually metered or as a set percentage of the bill. Whether a separate meter suits your property depends on the supply. We explain the options when we look at your board.
Do I need council approval for a granny flat?
You need building approval. The Queensland Government says any new granny flat requires building approval, and you should speak with your council about development approval before you build. Rules vary between councils, and a building certifier can advise on extra requirements. We don't arrange approvals. Once you have them, we wire the flat to the approved plans at a fixed price.
What smoke alarms does a granny flat need?
Your building certifier confirms what the flat needs as part of its building approval. For new homes approved from 1 January 2017, Queensland requires photoelectric smoke alarms, hardwired with battery backup and interconnected so they sound together. They go in bedrooms, hallways connecting bedrooms to the rest of the home, and on each storey. If you rent the flat out, it must meet smoke alarm requirements too.
Can I rent out my granny flat?
Yes. Since 2022, Queensland lets you rent a granny flat to anyone, related or not. Older approvals with occupancy conditions may need a change application first, and the Residential Tenancies Authority says you must have all relevant approvals before renting. As a landlord, you also have 90 days from the start of a new tenancy to fit a safety switch to the power points if there isn't one.
How much does it cost to wire a granny flat?
It depends on the flat, so we price it after seeing the plans, the main board and the supply. The main factors are the distance from the main board, how the cable gets there, whether the board or supply needs upgrading, the appliances, and how many power points and lights you want. You get one fixed price before work starts, and pay on completion by EFTPOS.
Can I do any of the granny flat wiring myself?
No. The Electrical Safety Office says installing a new power point or replacing a light switch is electrical work that must be done by a licensed electrician. DIY electrical work is treated as unlicensed work, which is illegal, and your insurer may refuse a claim for a fire caused by it. You can buy light fittings and fans yourself, but a licensed electrician must install them.
