Smoke Detectors in a Rented Home: Are They Required, and Who Installs and Maintains Them?

Smoke alarms are one of the few fixtures that matter more on the day nobody expects them to. They also sit awkwardly in most tenancy agreements: rarely named, often beeping for a battery by the second year, and occasionally found in a drawer at handover. Here is what SCDF actually requires, how the cost and upkeep usually split between landlord and tenant, and what to record at move-in and move-out.

Are smoke detectors mandatory in Singapore homes?

In practice, that means a condo or flat whose building plans went in after mid-2018 should already have at least one HFAD, and an older unit may or may not. "Fire safety works" here refers to changes such as relocating a fire door or altering walls that separate the home from common areas, not ordinary repainting or carpentry. If you rent out an older unit, the law may not force you to install one, but it is the cheapest safety upgrade you can make. Fire doors carry their own rules, which our guide to digital locks in rented homes covers.

Why does a rented home need a working smoke alarm?

The numbers are small against Singapore's housing stock, about 0.065% of 1.62 million dwelling units, but each case is someone's home and often someone else's property. Of the 304 electrical fires, 34 involved active mobility devices, which tenants commonly charge indoors. SCDF counted 6 fire deaths and 94 fire injuries needing hospital admission across all fires in 2025. For a landlord, a working alarm is also evidence that the home was reasonably equipped if a fire ever leads to an insurance claim; see our note on landlord insurance and tenant damage.

What does SCDF require of the device itself?

• How many: minimum one per storey; a storey with more than 70 m² of circulation area needs at least two.
• Where: along the circulation area or escape route, such as the living room, corridor or a staircase landing in a multi-storey home. Extra detectors in other rooms are optional.
• Interconnection: where two or more are installed, they must be linked, wired or wireless, so all of them sound when one is triggered.
• Cost: SCDF estimates S$50 to S$80 per unit for a built-in 10-year battery model, excluding installation, or S$40 or less for a dry-cell model that needs more frequent battery changes.

Who pays for smoke detectors in a rental: landlord or tenant?

Device prices from SCDF's HFAD guidance, excluding installation. Always confirm the split in writing before move-in.

The dry-cell battery is where most arguments start, because it is cheap and fails at 3am. Our explainer on the minor repair clause shows how the per-item cap usually handles items like this. If the landlord would rather avoid the question entirely, fitting the SCDF-recommended sealed 10-year model removes battery changes from the tenancy altogether.

What should landlords and tenants check at move-in and handover?

1. Before listing (landlord). Check the expiry or manufacture date printed on each unit. Replace anything near or past its 10-year life with a sealed-battery model and keep the receipt.
2. At move-in (both). Record each detector in the move-in inventory: location, working on test, and battery type.
3. During the tenancy (tenant). Test once a month, wipe off dust, and never cover a detector with tape or paint while cooking or renovating.
4. When it chirps or fails (tenant). Message the landlord or agent with a photo. Do not remove the unit and leave it in a drawer.
5. At handover (both). Test again as part of the handover inspection and compare against the move-in record.

Can a tenant remove a smoke detector, and can it be deducted from the deposit?

Disabling an alarm because it goes off during cooking is the most common cause we see at handover. It also defeats the point, since unattended cooking is the top cause of home fires. If the alarm keeps triggering, ask the landlord to relocate it along the escape route away from the kitchen rather than removing it. Charging a tenant for a premium smart detector set when a basic unit went missing is betterment, which is explained in our guide to the betterment rule for deposits.
