Smoke alarm, CO, and extinguisher rules for BC short-term rentals
The specific BC Fire Code requirements for short-term rental properties: where alarms must go, what counts as compliant, and the inspection failures we see most often.
Quick answer
BC short-term rentals must have interconnected smoke alarms on every floor and in every bedroom, CO alarms on every floor with fuel-burning equipment, and one 2A10BC fire extinguisher per floor. Alarms must be hard-wired or radio-linked (battery-only standalone units fail). Extinguishers must be wall-mounted with current certification tags. Posted evacuation plan is required.
How many smoke alarms do I need?
BC Fire Code 2018 (in force 2026) requires smoke alarms in every sleeping room, in the hallway outside each sleeping room cluster, and on every floor including basements. For a typical 3-bedroom Kelowna home, that's 4-6 smoke alarms minimum.
All alarms must be interconnected - when one goes off, they all go off. Hard-wired with battery backup is the gold standard. Radio-linked (wireless-mesh) is acceptable. Battery-only standalone alarms do not meet the interconnection requirement and fail compliance.
| Location | Required? | Why |
|---|---|---|
| Inside every bedroom | Yes | Sleeping occupants need direct alarm |
| Hallway outside bedrooms | Yes | Detects smoke before it enters bedroom |
| Each floor (including basement) | Yes | Catches fires that start away from sleeping areas |
| Kitchen | Photoelectric only | Ionization alarms get too many cooking false-alarms |
| Garage | Heat detector recommended | Smoke alarms get triggered by vehicle exhaust |
Where do CO alarms have to go?
Carbon monoxide alarms are required on every floor of the home that contains fuel-burning equipment OR that has a sleeping area where occupants could be exposed to CO drift from another floor.
Fuel-burning equipment means: gas furnace, gas range, gas water heater, gas fireplace, wood stove, pellet stove, attached garage with combustion vehicles. If you have any of these on a floor, that floor needs a CO alarm. Combination smoke/CO units satisfy both requirements.
What about fire extinguishers?
One 2A10BC-rated fire extinguisher per floor, wall-mounted, in a visible accessible location. The 2A10BC rating means the extinguisher can handle ordinary combustibles (A), flammable liquids (B), and electrical fires (C). It's the standard residential rating.
Each extinguisher must have a current inspection tag (annual visual inspection by a certified shop, or the dated paper tag from initial install if within the last 12 months). The pressure gauge needle must be in the green zone. Extinguishers with damaged gauges or expired tags fail inspection.
What's the evacuation plan requirement?
Every BC short-term rental must have a written, posted evacuation plan visible to guests. The plan should show: floor layout with all rooms, primary exit routes from each bedroom, secondary exit options (windows or balconies), location of fire extinguishers, the meeting point outside, and emergency contact numbers.
Most hosts post the plan on the inside of the main entrance door or on the fridge. A laminated 8.5x11" sheet is sufficient. The plan must be updated when the bedroom configuration changes.
What are the most common inspection failures?
We see the same handful of failures across Kelowna STR inspections. In rough order of frequency:
- Standalone battery-only smoke alarms not interconnected to others on different floors
- Missing CO alarm on the kitchen level when the home has a gas range
- Fire extinguisher present but with expired or missing inspection tag
- Smoke alarm in the bedroom is over 10 years old (alarms have a 10-year service life and fail open after that)
- Evacuation plan posted but not updated when an extra bedroom was added
- Combination smoke/CO unit installed correctly for smoke but not on the right floor for CO requirement
Frequently asked
Do battery-operated smoke alarms ever count as compliant?
Only if they're radio-linked (wireless-mesh) to the rest of the alarms in the house. Standalone battery-only alarms fail the interconnection requirement.
How often do I need to replace smoke alarms?
Every 10 years from the manufacture date. Check the back of the alarm - there's a date stamp. Alarms past 10 years old fail open and are an inspection failure even if they appear to work.
What's the difference between ionization and photoelectric alarms?
Ionization alarms detect fast-burning flames quickly but trigger frequent false alarms from cooking smoke. Photoelectric alarms detect smoldering fires and have fewer false alarms in kitchen areas. For BC STR compliance, both are acceptable in most rooms. Kitchen areas should use photoelectric to reduce cooking false alarms.
