The 2-5-10 Warranty in BC: What Every New Home Buyer Needs to Know

The 2-5-10 warranty in BC is one of the best protections you get as a new homeowner. But most buyers don't read it until something goes wrong.

That's backwards. You should understand what's covered before you sign anything. This matters.

Here's what BC's mandatory home warranty means for you.

TL;DR

• The 2-5-10 warranty is BC's mandatory home warranty insurance for new homes built by licensed residential builders
• Coverage splits into three periods: 2 years for materials and labour, 5 years for the building envelope, 10 years for major structural defects
• It's administered by BC Housing under the Homeowner Protection Act, SBC 1998, c. 31
• The warranty transfers automatically to future owners — protecting your resale value
• Owner-built homes are exempt, but require at least one year of occupancy before sale or rent, plus 10 years of disclosure to buyers

What Is the 2-5-10 Warranty in BC?

BC's 2-5-10 warranty is a type of mandatory insurance. A third party (not the builder) provides it. Every licensed builder in BC who builds a new home must offer this warranty.

The name describes the three coverage periods:

• 2 years — defects in materials and labour
• 5 years — building envelope failures (water penetration, weatherproofing)
• 10 years — major structural defects

It's governed by the Homeowner Protection Act (HPA), SBC 1998, c. 31. BC Housing administers the act.

No licensed builder can legally sell a new home in BC without this warranty. You cannot waive it. It's not optional. For most Metro Vancouver buyers, it's the most important legal protection they'll have for ten years.

Why Is Mandatory Home Warranty Required in BC?

BC didn't mandate this warranty for no reason.

In the late 1980s and 1990s, Metro Vancouver had a big problem. Many new homes had water leaks. This became known as the "leaky condo" crisis. Thousands of new buildings had defective building envelopes. Rain got in. Mould spread. Rot damaged the structure. Homeowners faced huge repair bills.

The Barrett Commission, formally the Commission of Inquiry into the Quality of Condominium Construction in British Columbia, investigated the crisis in 1998. Its report, issued in June 1998, led the Province to make warranty protection on new homes mandatory, license residential builders and create the Homeowner Protection Office.

Mandatory builder licensing and third-party home warranty insurance under the Homeowner Protection Act took effect on July 1, 1999. Its purpose: require new homes to carry third-party warranty insurance from an approved provider. Builders couldn't self-insure anymore. They had to back their work with independent coverage.

This one change made builders more accountable in BC's residential construction market.

How Does Each Layer of the 2-5-10 Warranty Work?

Each coverage period protects against a different failure type. Here's what each one actually protects.

The 2-Year Coverage: Materials and Labour

This coverage starts on the day you get the keys. It covers defects in workmanship and materials — things your contractor installed.

Practical examples:

• Plumbing installed incorrectly that fails in month 14
• Windows improperly flashed that leak after the first rainy season
• HVAC systems that malfunction due to incorrect installation
• Flooring that separates or buckles due to subfloor preparation failures

Two years might sound short. It's designed to catch problems that show up in the first two years of living in the home.

What it won't cover: cosmetic damage that isn't related to workmanship. A scuff on your hardwood floor from moving isn't a warranty claim. Fading paint from sun exposure isn't either.

The 5-Year Coverage: Building Envelope

This is the most significant layer for BC homes. Period.

The building envelope is everything that keeps water, wind, and moisture between inside and outside:

• Exterior cladding (wood, composite, fibre cement)
• Roofing systems and flashing details
• Windows and doors, including seals and weatherstripping
• Waterproofing membranes and drainage planes
• Any assembly where water gets inside and causes damage

If water enters through a covered envelope component and causes damage, you have five years to make a claim.

BC's coastal climate makes this layer essential. A damaged envelope in Coquitlam or North Vancouver might not show damage for two or three years. A shorter coverage period would mean no protection by the time you notice the problem. Five years closes that gap.

The 10-Year Coverage: Structural Defects

This protects against major structural failures:

• Foundation settlement or cracking that compromises structural integrity
• Load-bearing wall failures
• Roof structure failures
• Any defect that undermines the structural soundness of the home

Structural failures are rare in properly built homes. But they're catastrophic when they happen. They often develop slowly over years, not months. A decade-long window gives you time to identify slow-moving problems before you lose legal recourse.

Critically, this coverage transfers when you sell. If you sell at year 7, the buyer inherits 3 more years of structural protection.

Who Provides the 2-5-10 Warranty in BC?

Your builder doesn't write the warranty. A BC Housing-approved warranty provider does. This separation is important. If your builder fails, your coverage stays in place.

BC Housing lists the home warranty insurance companies authorized by the BC Financial Services Authority. The list includes:

• Travelers Canada, with policies issued by St. Paul Fire and Marine Insurance Company
• Trisura Guarantee Insurance Company, represented by Pacific Home Warranty Insurance Services, a Langley-based provider
• Aviva Insurance Company of Canada, represented by National Home Warranty Insurance Services
• Intact Insurance Company, represented by WBI Home Warranty Ltd.
• The New Home Warranty Insurance (Canada) Corporation, represented by Canadian Home Warranty Protection Program

BC Housing publishes a current list of approved providers at bchousing.org. Always verify your builder's warranty provider is on that list before signing a purchase agreement. Don't take the builder's word for it. Verify independently.

Each provider handles claims differently. But minimum coverage standards are set by the HPA. No approved provider can offer less than the statutory minimums.

What Isn't Covered Under the 2-5-10 Warranty?

Knowing the exclusions is as important as knowing the coverage.

Common exclusions:

• Normal wear and tear (paint fading, carpet compression, minor settling cracks)
• Damage from unauthorized repairs or alterations by the homeowner
• Pest or insect infestations — unless caused by a covered construction defect
• Acts of nature or extreme weather events
• Cosmetic issues not connected to a structural or workmanship defect
• Landscaping, detached structures, or outbuildings

Maintenance failures are not covered. If your roof fails because you didn't fix visible flashing damage for two winters, the warranty provider will likely call it a homeowner maintenance problem. The warranty doesn't mean you skip basic upkeep.

You don't need to become a trades expert. But annual inspections, caulking checks, and roof reviews protect your legal position if you ever need to make a claim.

Does the 2-5-10 Warranty Apply to Renovations?

This is one of the most common questions we hear. The answer depends entirely on scope.

The mandatory 2-5-10 warranty applies specifically to new homes. Standard cosmetic renovations — new kitchen cabinets, flooring, paint, fixture replacement — fall outside the HPA warranty scope entirely.

But major renovation work is different.

If a renovation project is an applicable building envelope renovation under BC Housing's rules, the contractor must be a licensed residential builder with warranty insurance in place before the work starts. Structural renovations and additions to an existing home aren't covered by the new home warranty, although a renovation that is extensive enough can be treated as a new home. Check BC Housing's guidance and talk to your builder first.

The threshold isn't always obvious. A good licensed contractor explains the details for your project before work starts. It's much easier to solve warranty questions upfront than to argue about them later.

If your contractor can't answer your warranty questions directly, that's information worth having.

Does the 2-5-10 Warranty Apply to Laneway Homes?

In most cases, yes.

If you hire a licensed builder to build a laneway home in Vancouver, Burnaby, or Metro Vancouver, they must provide 2-5-10 warranty coverage. The same rules apply as for any new home.

The exception is the owner-builder path.

If you act as your own general contractor for the laneway home, you can get an owner-builder authorization from BC Housing. This lets you skip mandatory warranty insurance. But there are conditions:

1. You must live in the home for at least one year after occupancy before selling or renting it 2. If you sell within 10 years of occupancy, you must give buyers an Owner Builder Disclosure Notice

You also have to pass BC Housing's owner builder exam to get the authorization. Breaking the occupancy or disclosure rules leads to serious legal consequences under the HPA.

For most homeowners, hiring a licensed builder is easier and more valuable. You get documented warranty coverage from the day you get the keys. You can sell sooner if you need to. Lenders and future buyers recognize this paperwork immediately.

How Do You Make a 2-5-10 Warranty Claim in BC?

The process is straightforward — but only if you follow the right sequence.

Step 1: Document everything immediately

Take dated photographs. Note when you first observed the issue and how it has changed. Keep all written communication with your builder.

Step 2: Contact your warranty provider — not your builder

Your warranty provider handles claims. Find their contact information in your warranty documentation from possession. Don't wait for your builder to connect you.

Step 3: Submit a written claim within the coverage period

Phone calls don't protect your rights. Written claims do. Submit within the active coverage period. Miss the deadline and you lose a valid claim — even if the problem started during coverage.

Step 4: Inspection and assessment

The warranty provider sends an inspector to assess the defect. They determine whether it falls within covered categories under your policy.

Step 5: Resolution

If the claim is accepted, the warranty provider makes sure the covered defect is repaired.

Store your warranty certificate with your title documents. Don't bury it in a drawer. If you ever need it, you'll need it quickly.

What Should You Ask Your Builder Before Signing?

Five questions every buyer should ask:

1. What is your BC Housing builder licence number? — Every licensed builder has one. Verify it yourself at bchousing.org before signing. 2. Who is your warranty provider, and are they on BC Housing's approved list? — Confirm independently. 3. Can I see a sample warranty certificate for this type of project? — Understand the exact coverage before possession, not after. 4. Does the warranty transfer automatically if I sell? — It should. Get confirmation in writing. 5. Are there project-specific exclusions I should know about? — Custom features sometimes require explicit warranty discussion.

Asking these five questions before signing prevents harder conversations years later. See how CoreVal approaches custom homes across Metro Vancouver's North Shore, Tri-Cities, Burnaby and Fraser Valley.

Ask early. Ask specifically. Keep everything in writing.

How Does the 2-5-10 Warranty Affect Resale Value?

Significantly — especially within the first 10 years.

A home with an active 10-year warranty is more attractive to buyers, and buyers and their lawyers will want to see the warranty documents when a home is sold within the warranty period.

If you sell within the first ten years, treat your warranty certificate, possession date documentation, and any claims history as transaction assets. Keep them organized. Buyers and their lawyers will ask for them.

If you lose your documentation, contact BC Housing. BC Housing's New Homes Registry shows whether a home is covered by home warranty insurance. Keep your original documents to avoid this.

How Does BC's 2-5-10 Warranty Compare to Other Provinces?

BC's coverage structure is similar to other provincial new home warranty programs. But the specifics matter.

BC's 2-5-10 structure differs from other provinces. Ontario's Tarion warranty covers 1 year for defects in work and materials, 2 years for items such as water penetration through the building envelope and defects in plumbing, electrical and HVAC systems, and 7 years for major structural defects.

Alberta's program is closest to BC's: 1 year for materials and labour, 2 years for delivery and distribution systems, 5 years for the building envelope and 10 years for structural defects.

If you buy rental properties in different provinces, these differences matter.

How Do You Choose a Licensed Builder in Metro Vancouver?

Start with BC Housing's builder registry at bchousing.org.

The registry lists every currently licensed residential builder in BC. You can verify:

• Active license status
• License category (residential builder, owner-builder)
• Any enforcement actions on record

A builder not in the registry cannot legally build a new home in BC. You can't proceed with any unlicensed contractor for new residential construction.

Beyond the registry check:

• Confirm their warranty provider is on BC Housing's approved list
• Ask to see completed homes (photos, addresses, references from recent buyers)
• Verify they pull permits in their own name — not yours
• Ask specifically how they handle warranty claims on past projects

CoreVal Homes is a licensed builder on the BC Housing registry, and its new homes are backed by Pacific Home Warranty. Every custom home build includes 2-5-10 home warranty coverage.

FAQ

Q: Is the 2-5-10 warranty the same as a home inspection?

No. A home inspection is a one-time check of visible systems. It happens before you buy. The 2-5-10 warranty is ongoing insurance. It protects you from builder defects for up to 10 years after you move in. They serve different purposes. An inspection shows what exists today. The warranty protects you from problems that develop over time.

Q: Does the 2-5-10 warranty cover mould?

It depends on the cause. Mould from a covered building envelope failure — water leaking through a defective part — is typically covered. Mould from poor ventilation or humidity control by the homeowner is typically not covered. Each claim is evaluated based on what caused it. Good ventilation maintenance protects both your health and your warranty.

Q: What happens if my builder goes out of business during my warranty period?

Your coverage stays active. This is the key advantage of third-party insurance. If your builder closes or goes bankrupt, the warranty provider handles your claim. You don't lose protection because your builder failed. Before you move in, confirm your warranty is with an approved third-party provider — not the builder — and you're protected no matter what.

Q: Can I purchase extended warranty coverage beyond the standard 2-5-10 periods?

Some approved warranty providers offer extra coverage beyond the standard 2-5-10 periods. These are separate from the required warranty. They extend coverage periods or add new categories. Ask your warranty provider what extras are available for your home before you move in. It's easier to add coverage upfront than to get it later.

Q: Does the 2-5-10 warranty apply to laneway homes and secondary suites?

Yes, for laneway homes built by a licensed residential builder: they must carry full 2-5-10 coverage under the same rules as any new home. Owner-built laneway homes follow the owner-builder rules instead: an authorization and exam, at least one year of occupancy before selling or renting, and a disclosure notice to buyers for 10 years. A secondary suite added inside an existing house is a renovation, so the new home warranty doesn't apply to it.
