Basement suites are everywhere in Burnaby, from classic Vancouver Special homes in Edmonds, Royal Oak and South Slope to newer houses with legal secondary suites. They’re also the first place water goes. A leak upstairs, a perimeter drain failure or a sewer backup can leave tenants without a home and owners with a big repair bill. Here’s how landlords and tenants should handle it. General information only. BC’s Residential Tenancy Act, your tenancy agreement and your insurance policies govern specific situations.

Why Basement Suites Are So Vulnerable
- Lowest level: groundwater, perimeter drain failures and sewer backups hit here first.
- Directly below the main floor: upstairs bathrooms, kitchens and laundry leak down into the suite.
- Full kitchens and bathrooms in the suite add more plumbing that can fail.
- Finished floors and walls over concrete trap moisture.
- Two households means communication delays when something goes wrong.
Tenants: First Steps
- Stop the water if you safely can (fixture valve or main).
- Tell the landlord immediately, by phone and in writing, with photos.
- Move belongings to a dry place.
- Call your tenant insurer if your things are damaged.
- Keep receipts for emergency costs.
Landlords: First Steps
- Get emergency extraction and drying started right away; BC law treats major leaks as emergency repairs.
- Document the cause and damage.
- Notify your insurer (you’ll typically need a policy that properly covers a rental suite).
- Follow proper notice rules for entering the suite for non-emergency work.
- Talk with your tenant about timelines and whether the suite is livable.
Who Usually Pays for What
| Item | Usually covered by |
|---|---|
| Drywall, flooring, cabinets, fixtures | Owner’s home insurance (if the cause is covered) |
| Tenant’s furniture, clothes, electronics | Tenant’s insurance |
| Tenant’s temporary accommodation | Tenant’s insurance (additional living expenses) |
| Lost rental income | Owner’s policy, if it includes rental income coverage |
Tenants should carry tenant insurance, because the owner’s policy usually won’t cover their belongings.
Mould and Health
Burnaby’s damp climate means a basement suite that isn’t dried properly can develop mould quickly, affecting tenants’ health and the suite’s habitability. Professional drying with moisture verification protects everyone. See mould after water damage.
Preventing Suite Water Damage
- Have perimeter drains inspected and flushed. See perimeter drains.
- Install a backwater valve if there’s a floor drain in the suite.
- Put leak sensors under the upstairs laundry, dishwasher and both water tanks.
- Replace appliance hoses with braided stainless.
- Show tenants where the main shut-off is.
- Use moisture-tolerant flooring like luxury vinyl plank in the suite.
