Custom Home Warranties in BC: What 2-5-10 Actually Covers in a Burnaby Build

What does the BC 2-5-10 warranty cover in a Burnaby custom home?

The BC 2-5-10 warranty covers materials and labour for two years, the building envelope (including unintended water penetration) for five years, and structural defects for ten years. It's mandatory on every new home built by a Licensed Residential Builder in BC under the Homeowner Protection Act. In a Burnaby build, the envelope coverage carries the most practical weight because of climate, slope sites, and the city's tree canopy.

A homeowner once asked me, with full sincerity, whether the warranty was something we offered as a service. I told her it was a legal requirement, not a marketing position, and that the more interesting question wasn't whether the warranty existed but whether the builder she was about to sign with was actually licensed to issue it. That question gets less attention than it deserves. Anyone hiring a Burnaby custom home builder should be able to ask it and get an answer in thirty seconds.

This piece is the Burnaby-specific read on the 2-5-10. The general mechanics are covered in our explainer on the BC 2-5-10 warranty. What's here is the working builder's view of how each coverage layer maps to the actual risk on a Burnaby build, what owner-builder authorization does and doesn't change, and how to verify the person across the table from you is licensed to do what they say they do.

The legal floor: it's mandatory, and the law says so

The Homeowner Protection Act, currently codified as the Homeowner Protection Act, SBC 1998, is the statute that creates the program. Two sections do most of the work.

Section 14(1) makes the licensing requirement absolute: "A person must not carry on the business of a residential builder unless licensed." Section 22(1) makes the warranty requirement absolute: "A person must not build a new home unless the new home is registered for coverage by home warranty insurance." Those aren't aspirational targets. They're prohibitions, and a builder who builds without either is committing an offence under the Act.

BC Housing administers the program. The coverage architecture is the one most owners know by name:

• Two years on materials and labour — defects in workmanship and materials. Within that period, twelve months for general defects in a detached home, and twenty-four months for: electrical, plumbing, heating, ventilation, and air conditioning delivery and distribution systems; for exterior cladding, caulking, windows, and doors that may lead to detachment or material damage; and for any defect that renders the home unfit to live in.
• Five years on the building envelope — defects "including unintended water penetration that could cause damage" in BC Housing's language.
• Ten years on structural defects — defects in load-bearing parts or the overall structure, including defects that make the home unfit to live in.

Those minimums are floors, not ceilings. Some warranty providers offer enhanced coverage; the statutory baseline is what every Licensed Residential Builder in BC must carry.

Why "Licensed Residential Builder" is the phrase that matters

There's a designation question buried inside the warranty conversation, and most owners don't ask it. Under section 14(5) of the Homeowner Protection Act, a person who isn't a licensed residential builder must not "use or display the designation 'Licensed Residential Builder'" or imply they hold the licence in any way. That's the phrase to listen for in a builder interview. Not "we've been building for twenty years," not "we carry insurance," not "warranty isn't a problem" — the specific phrase, and the licence number that backs it up.

BC Housing publishes a public registry. Before you sign a contract, look the builder's company up. The registry shows the licence status, the warranty provider on file, and any orders or conditions on the licence. A two-minute search saves a ten-year problem.

The CHBA BC Master Residential Builder designation is a separate credential — a CHBA BC certification that requires "a total of ten years' experience in the residential construction industry, including five of which are at the management level," along with references from a warranty provider, clients, and subtrades, and a passing grade on the required coursework. It's not the same as the licence. The licence is the floor; the CHBA BC designation is an additional credential.

How each coverage layer maps to a Burnaby build

The warranty is identical across the province. What changes from city to city is which layer of coverage is most likely to be exercised, and on a Burnaby custom home the answer isn't subtle.

Two years: materials and labour

The first two years are when finishing and workmanship defects surface. Doors that don't hang true, trim that's pulling at the corners, grout cracking at non-structural joints, paint failures on south elevations, hardware that's failing under daily use. Twelve months of normal occupancy puts the finishes through their first real test.

The Burnaby-specific notes here are minor. Coastal humidity drives a slightly higher rate of cabinet wood movement in the first winter than dryer climates. Heating systems in highly air-tight envelopes need to be commissioned properly — the Step Code Step 5 piece covers why. Otherwise, this layer is the same conversation everywhere in BC.

Five years: the building envelope

This is the layer that earns its keep in Burnaby. "Unintended water penetration that could cause damage" is the language, and Burnaby's combination of high annual rainfall, deep eaves under heavy tree canopy, sloped sites with complex drainage, and a building stock that's increasingly air-tight makes the envelope the single most consequential assembly on the home.

Where the envelope risks actually sit on a Burnaby build:

• Window head and sill details. A Step-3 or Step-5 envelope with deep window reveals — common on the modern Burnaby Heights and Capitol Hill builds we work on — demands sill flashing that genuinely drains, head flashing that genuinely sheds, and a continuous water-resistive barrier that's lapped correctly. We've written about the glazing-side risks in windows and glazing in a Burnaby winter.
• Roof-to-wall transitions. Burnaby's heavy tree canopy means roofs collect debris year-round. Gutters overflow if they're not cleaned, and a backed-up gutter under heavy fascia is the textbook entry point for envelope failure.
• Below-grade waterproofing. Daylight basements on Capitol Hill, Buckingham Heights, and Cariboo Heights are sitting in saturated soil for months of the year. The waterproofing membrane, the drain rock and weeping tile, and the perimeter drain connection back to the storm system carry envelope coverage that gets exercised more often than owners expect.
• Deck and balcony interfaces. A modern flat-roof deck over conditioned space is a building-envelope question, not a finish question. The membrane, the flashing at the door threshold, and the drainage all sit inside the five-year window.

Builders who treat the envelope as a five-year insurance position rather than a thirty-year asset are the builders who get the claims. The detail decisions made during construction determine whether the envelope coverage is dormant or busy.

Ten years: structural defects

The ten-year layer covers "defects in load-bearing parts or the overall structure" including, in BC Housing's language, defects that make the home unfit to live in. On a Burnaby slope lot, this is the layer the geotech and the structural engineer are quietly designing against.

Foundation failures, retaining wall movement, structural slab cracking beyond cosmetic, framing failures — these are the categories the ten-year covers. They're rare on well-designed homes and they're not rare on poorly-designed ones. The cost of doing the geotechnical work properly at the start of a project is a small fraction of what a structural claim costs to remediate in year eight.

The structural decisions on a Burnaby hillside lot — pile depths, retaining systems, drainage behind foundation walls, the shoring strategy during excavation — are documented in foundations on Burnaby hillside lots. Each of those decisions sits inside the ten-year envelope.

The claims process: how it actually works

Owners hope they never use the warranty. Some will. The mechanics are worth knowing in advance.

A defect is reported in writing to both the builder and the warranty provider. Most warranty providers require notice within a defined window after the defect is observed, and the policy will state the form the notice must take. The builder is typically the first responder — most defects in the two-year window are resolved by the builder directly, without the warranty being formally exercised.

If the builder can't or won't address the defect, the warranty provider steps in. The provider's adjusters investigate, determine whether the claim falls within coverage, and either authorise repairs or pay out. The full process, including the dispute pathway if the owner and the provider disagree, is laid out in the policy itself. BC Housing's published guidance is clear: "the policy is a legal contract with the warranty provider," and owners should read it carefully when they receive it at occupancy.

Two practical points from our experience. The first is to keep the documentation an owner is given at handover — the warranty certificate, the builder's manuals, the commissioning reports, the maintenance schedule. Claims are easier when the paper exists. The second is to maintain the home in line with the warranty's stated requirements. Annual gutter cleaning, periodic envelope inspection, mechanical service intervals — these are reasonable requirements, and they're usually conditions of the warranty. A failure caused by a maintenance lapse may not be covered.

The owner-builder exception, and its limits

There's a narrow legal pathway under the Homeowner Protection Act for an individual to build their own home without a Licensed Residential Builder and without third-party warranty insurance. It's called the Owner Builder Authorization, and BC Housing's published guidance describes it bluntly.

An authorised owner builder is "exempt from further licensing and the requirement to obtain third-party home warranty insurance," but is "personally liable for any defects in construction for 10 years should they sell the home" — and liable for the same coverage periods as a Licensed Residential Builder: two years for materials and labour, five years for envelope, and ten years for structural. The exemption transfers the risk; it doesn't eliminate it.

There's also a sale restriction. Under section 20.1(1) of the Act, an owner builder must not sell or offer to sell a new home while the home is being constructed, or within the prescribed period after the home has been built — which BC Housing's published guidance puts at one year from first occupancy, with limited exceptions for undue hardship. Section 21(2) requires that subsequent purchasers within the warranty period receive a disclosure notice stating whether or not the home is covered by home warranty insurance.

For most owners building custom homes in Burnaby as a long-term residence and not a build-to-sell, the owner-builder pathway is technically available and practically rarely the right call. The lien risk, the construction defect liability, the difficulty of insuring the project during construction, and the absence of the dispute pathway a third-party warranty provides are real considerations. We covered this briefly in the lot evaluation post. The CHBA BC Master Residential Builder designation requires "a recent reference letter from your home warranty provider" — a builder who can supply that is a builder who's been carrying the warranty on every project, year after year.

How to verify a builder before you sign

The thirty-second checklist for a homeowner choosing a custom builder in Burnaby:

• Ask for the licence number. Look it up on the BC Housing public registry. Confirm the status is active, the company name matches, and no conditions are noted.
• Ask which warranty provider the builder uses. Confirm with the provider that the builder is currently in good standing.
• Ask for a recent project's enrollment letter. A builder who's enrolled homes recently has it on hand.
• Ask whether the builder holds any additional credentials — CHBA BC Master Residential Builder, Net Zero, etc. These aren't required, but they signal investment in the trade.
• Ask whether the builder has had any claims in the last three years and how they were resolved. The answer matters less than the candour.

That's a fifteen-minute conversation. The fuller list of contract-stage questions is in 12 questions to ask before signing a custom home contract. The Burnaby lot eligibility tool is a separate, earlier conversation about whether your lot supports the home you have in mind, not about the builder.

The warranty is the floor. It is not a strategy. The builder you want is one who treats the ten-year structural and five-year envelope as a thirty-year design problem, and the warranty as the legal underline beneath it.

Where we sit in this

We're licensed, we carry warranty insurance on every project, and we hold the CHBA BC Master Residential Builder designation. None of that is a marketing flourish — it's the floor the law and the trade ask any builder to meet. The work we'd rather be judged on is whether ten years from issuance, your envelope is dry, your foundation is straight, and your finishes still look like they did at handover. That's the build we're trying to make.

If you're starting a custom home in Burnaby and want a candid conversation about how the warranty maps to your specific lot and design, that's where we begin.
