In Singapore, a Home Fire Alarm Device (HFAD), usually a smoke detector, is mandatory in all new homes, including new HDB flats, and in existing homes doing fire safety works (such as relocating fire doors or altering walls next to common areas) with plans submitted from 1 June 2018. Other existing homes are not required to have one, but SCDF strongly encourages it. An HDB flat needs at least one, mounted on the ceiling along the escape route, such as the living room or corridor. SCDF puts the cost at about $50 to $80 for a unit with a 10-year built-in battery. Fire extinguishers are not required in homes, but they and fire blankets are useful, and SCDF teaches how to use both.
A smoke alarm costs less than a family dinner and buys you the minutes that matter most. Here is what the rules ask, and what a well-prepared home looks like.
Quick facts
- HFADs are mandatory for new homes and homes doing fire safety works, with plans submitted on or after 1 June 2018.
- Single-storey homes (HDB flats, condo units): at least 1 smoke detector along the escape route.
- Multi-storey homes: at least 1 per storey; 2 if a storey’s circulation area is over 70m².
- SCDF recommends units with a 10-year built-in battery, about $50 to $80 each before installation.
- Devices must meet EN 14604, UL 217 or AS 3786.
- In 2025, SCDF recorded 1,051 residential fires; unattended cooking (318) was the top cause.
Do I have to install a smoke detector?
| Your home | HFAD required? |
|---|---|
| New home (new HDB flat, new condo, new landed house) | Yes, mandatory |
| Existing home doing fire safety works, plans submitted from 1 June 2018 | Yes, mandatory |
| Existing home with ordinary renovation only | Not mandatory, strongly encouraged |
| HDB public rental flat | Households were made eligible for one free unit, installed, under an HFAD assistance scheme that began in 2018; tenants maintain it |
“Fire safety works” are addition and alteration works such as installing or relocating fire doors, roofing over an open balcony, or altering walls that separate your unit from common areas. Retiling or new cabinets alone do not trigger the rule.
Choosing and fitting one
- Pick a smoke detector, not a heat detector. SCDF says smoke detectors give earlier warning.
- Check the standard: EN 14604, UL 217 or AS 3786 on the box.
- Prefer a 10-year sealed battery. Cheaper dry-cell units (about $40 or less) need new batteries at least once a year.
- Mount it on the ceiling along the escape route: the living room or corridor, not inside a bedroom, storeroom or bathroom.
- Press the test button regularly, and replace the unit when the low-battery alert sounds, the test fails, or it reaches the end-of-life date.
Fire extinguishers and fire blankets
No law requires an extinguisher in an HDB flat, but SCDF’s Civil Defence Emergency Handbook teaches both tools, and a small household set kept near the kitchen exit is sensible. Use them only if it is safe; if not, get out and call 995.
| Tool | How to use it (SCDF) | Best for |
|---|---|---|
| Fire extinguisher | P.A.S.S.: Pull the pin, Aim at the base of the fire, Squeeze the lever, Sweep side to side | Small fires you can approach safely |
| Fire blanket | Switch off the heat or power if you can, pull the straps, stretch the blanket over the flames | A pan or small kitchen fire |
| Wet cloth | Cover a burning wok or pan, then turn off the gas | Wok and pan fires |
| Water | Never on oil or other flammable liquids; it spreads the fire | Not for cooking oil fires |
If a fire starts at home
- If you cannot put it out quickly, leave and call 995.
- Shut the door of the burning room behind you to slow the smoke.
- Use the stairs, never the lift.
- Stay low under smoke.
- Neighbours on the fire floor or within two floors above should evacuate immediately.
For the two biggest home risks, never leave cooking unattended, and avoid charging batteries or mobility devices unattended for long periods or overnight. SCDF also warns against non-original batteries.
The WahLiao Verdict
Even if the law does not require it for your flat, fit one smoke detector with a 10-year battery on the ceiling outside the bedrooms this weekend; it is a small spend for a large peace of mind. Keep a fire blanket in the kitchen, learn P.A.S.S. once, and make it a family rule that phones and scooters do not charge overnight. Then press the test button on the first day of every month, and relax.
Questions people ask
My BTO flat came with a smoke detector. Can I remove it?
No. It is there because HFADs are mandatory in new homes. Keep it working, test it, and replace it when it reaches its end of life.
Where should the detector go in a 4-room flat?
On the ceiling along the escape route, such as the living room or the corridor outside the bedrooms. At least one is required for single-storey homes where the rule applies.
How often should I change the battery?
Dry-cell units need new batteries at least once a year. Units with a built-in battery last about ten years, after which the whole device is replaced.
Does HDB fire insurance replace a smoke detector?
No. Insurance helps pay for damage afterwards; a detector warns you early enough to get out. They do different jobs.
