QLD Smoke Alarm Laws: The 1 January 2027 Deadline Explained

Under QLD smoke alarm laws, every existing home, townhouse and unit in Queensland must have interconnected photoelectric smoke alarms by 1 January 2027. They go in every bedroom, in hallways that connect bedrooms, and on each level. Homes being sold or leased have had to meet the same standard since 2022, so 2027 is the date it reaches everyone else. We supply and install compliant alarms for $181.50 each including GST.

What changes on 1 January 2027

The rule isn’t new. It was phased in from 2017, and 1 January 2027 is the last group of homes reaching it. The Queensland Government’s smoke alarms page states that all existing private homes, townhouses and units require interconnected photoelectric smoke alarms by that date.

The Queensland Government’s early responsibilities page puts it this way: “From 1 January 2022, these requirements will apply to all houses leased and sold. From 1 January 2027, they will apply to all homes.” In the Fire Services Act 1990, the older smoke alarm rule in section 147Y expires on 31 December 2026, which leaves the newer standard in section 147Z for every home.

What a compliant smoke alarm must be

An alarm counts only when it ticks every box below. The type, the standard and interconnection are on the Queensland Government page.

The age and testing rules are in sections 147Z and 148A of the Act. The power options are on the Queensland Fire Department’s smoke alarms page. The manufacture date is printed on each alarm.

Where the alarms must go

The Queensland Government lists three places: every bedroom, hallways that connect bedrooms, and each level of the home.

• One in every bedroom.
• One in each hallway that connects bedrooms to the rest of the home. With no hallway, the alarm goes between the bedrooms and the rest of that level.
• At least one on every level. A level with no bedrooms needs one in the most likely path out of the home.

A three bedroom single storey home with one hallway needs four alarms. Our guide to how many smoke alarms a Queensland home needs shows how to count yours.

What does it cost to comply?

We supply and install interconnected photoelectric smoke alarms with a 10 year lithium battery for $181.50 each including GST. Your total is the number of alarms multiplied by $181.50.

Hardwired (240 volt) alarm replacement is quoted separately. We check what’s on your ceilings, count what your floor plan needs, and give you a fixed price in writing before any work starts. Quotes are free. The service is on our smoke alarm installation Brisbane page, and other totals are in our smoke alarm installation cost guide.

Rentals and homes being sold already comply

Under section 147Z of the Act, the standard applies once a new tenancy starts or an existing tenancy is renewed after 31 December 2021, or once the owner agrees to sell after that date. Landlords also have testing and cleaning duties before each tenancy.

Our guide to smoke alarm compliance for Queensland rental properties sets out those duties step by step.

What are the penalties?

The maximum penalty for an owner who doesn’t install compliant smoke alarms is 5 penalty units, under section 147Z of the Act. The same maximum applies to not replacing an alarm that’s out of date or doesn’t work.

We haven’t converted penalty units to dollars, because the value changes. The Queensland Government’s penalty unit costs page explains penalty units and links to the current value.

Common questions about the 2027 smoke alarm laws

Can an alarm go somewhere else if steam keeps setting it off?

Yes, within limits. Section 148 of the Act lets an owner put an alarm at another location that will still warn the people in the home, when the required spot is impracticable. The Act’s example is an alarm set off by steam from a bathroom or fumes from a kitchen.

Do caravans and motorhomes need a smoke alarm?

Registered ones do. The Queensland Government states that all registered caravans and motorhomes must be fitted with a photoelectric smoke alarm.

Can you check the alarms I already have?

Yes. We check each one for type, age and interconnection when we quote. An existing alarm that meets every requirement stays, and the quote covers only what’s missing, expired or not interconnected.
