That pipe isn’t a fix.
Since March 8, 2024, every new home in BC has to be built with a radon “rough-in”: a sealed pipe under the floor that’s ready for a fan. But the code doesn’t require the fan, and the pipe alone doesn’t prove your air is safe. Only a test can tell you.
Why it matters here
- Radon is an invisible, odourless gas that seeps up from the ground.
- Health Canada says it’s the #1 cause of lung cancer in people who don’t smoke.
- The Central Okanagan is considered a high-radon area.
What the pipe does
- It’s ready for a fan. The building code doesn’t require one.
- Some older homes only got a short capped pipe that vents nothing.
How to test
- Use a long-term (3-month) test, ideally over fall and winter. BC Lung Foundation kits start at about $63, lab results included.
- If your result is 200 Bq/m³ or higher, Health Canada says to hire a certified radon mitigation professional.
