Smoke Alarm Installation Brisbane | Compliance Guide & Costs

Queensland Smoke Alarm Laws: What Every Brisbane Homeowner Needs to Know

Since January 2022, all Queensland homes sold, leased or with a new or altered lease must have interconnected photoelectric smoke alarms in every bedroom, hallway connecting bedrooms and on every level. By 2027, ALL Queensland homes must comply — regardless of sale or lease. For homeowners across North Lakes, Redcliffe, Mango Hill, Chermside and Aspley, here is your complete compliance guide.

Queensland Smoke Alarm Requirements

Smoke Alarm Installation Costs

Costs depend on the number of alarms needed, whether existing wiring can be used and ceiling access difficulty.

Hardwired vs Wireless Interconnected

Hardwired (240V with battery backup)

• Most reliable — powered by mains electricity
• Battery backup for power outages
• Requires electrician for installation
• Best for new builds and renovations
• Connected via cable between alarms

Wireless Interconnected (10-year lithium battery)

• No new wiring needed — easier retrofit
• 10-year sealed lithium battery
• RF wireless interconnection between alarms
• Good for older homes where running cable is difficult
• Can be installed by homeowner (but electrician recommended)

What Happens If You Do Not Comply?

• Fines up to $7,732 for non-compliance
• Cannot legally sell or lease your property
• Insurance may not cover fire damage in non-compliant homes
• Most importantly — non-compliant alarms put lives at risk

Combine with Other Safety Upgrades

When upgrading smoke alarms, consider also addressing:

• Switchboard upgrade — safety switches on all circuits
• Electrical safety inspection
• Surge protection
• LED lighting upgrade — remove fire-risk halogen downlights
• Ceiling fan installation
• Powerpoint upgrades
