What does the 2-5-10 home warranty actually cover in BC?

BC's 2-5-10 home warranty is mandatory coverage on all new homes built by a Licensed Residential Builder — and it's one of the strongest new home warranties in Canada. The numbers refer to the duration of coverage across three tiers, and understanding what falls into each tier can save you thousands of dollars in disputes down the road.

The Three Coverage Tiers Explained

The "2" covers labour and materials defects, but it's actually a bit more nuanced than just "two years on everything." Detached homes get 12 months of general labour and materials coverage, while common property in strata buildings gets 15 months. The full 24-month window applies specifically to major systems — think electrical, plumbing, HVAC, exterior cladding, windows, and doors. So if your heat pump fails due to a defective installation in month 20, you're covered. If a baseboard in a bedroom is poorly finished, you've got 12 months to flag it.

The "5" covers building envelope defects, which in Vancouver's wet climate is arguably the most important tier. This includes water penetration through the roof, walls, windows, and foundation. Given that Metro Vancouver gets over 1,200mm of rain annually and leaky condo syndrome cost BC homeowners billions in the 1990s, the Province specifically designed this tier to protect against moisture-related failures. If your new townhouse starts showing water intrusion through the exterior wall system in year three, this is your coverage.

The "10" covers structural defects — load-bearing components like foundations, beams, columns, and framing. This is your protection against the most serious and expensive failures. Structural issues are rare in new construction, but when they occur, repair costs can be catastrophic. Coverage limits are $200,000 for detached homes and $100,000 per strata unit.

What's NOT Covered

The warranty doesn't cover normal wear and tear, damage caused by the homeowner (improper maintenance, alterations, or neglect), or issues caused by third parties. It also won't cover defects you knew about at purchase but didn't disclose. Cosmetic issues that don't affect function or livability are often excluded after the initial defect reporting period — so document everything thoroughly during your first-year walk-through.

Vancouver-Specific Context

Under BC's Homeowner Protection Act, this warranty is not optional — any builder constructing a new home (including laneway houses and coach houses) must be a Licensed Residential Builder registered with BC Housing, and the home must be enrolled in an approved warranty program. Warranty providers include National Home Warranty, Travelers, and others approved by BC Housing. You can verify your builder's licensing status and warranty enrollment at bchousing.org before you sign anything.

This matters especially in Vancouver's multiplex boom — with 3-6 unit multiplexes now being built across former single-family lots under the new R1-1 zone, buyers need to confirm that the builder is properly licensed and the units are warranty-enrolled.

Next Steps

If you're buying a new home, ask the builder for the warranty certificate and confirm enrollment directly with the warranty provider — don't just take the builder's word for it. If you're a current owner with a potential warranty claim, document the defect in writing, notify your builder and warranty provider promptly, and keep records of all communications. Disputes that can't be resolved directly can be escalated through your warranty provider's dispute resolution process.
