BC Realtor's Guide to the 2-5-10 New Home Warranty (Homeowner Protection Act 2026)
BC's Homeowner Protection Act mandates a 2-year defect, 5-year building envelope, and 10-year structural warranty on every new home built by a licensed residential builder. The warranty transfers automatically on resale — making it a critical part of any new construction buyer's due diligence and a key marketing advantage for sellers of newer homes. Learn what each period covers, what voids coverage, how strata warranty works differently, and your obligations when acting for new construction buyers.
The Homeowner Protection Act — BC's Mandatory Warranty Framework
BC's Homeowner Protection Act (HPA), administered through the Homeowner Protection Office (HPO), has required mandatory third-party warranty coverage on all new homes built by licensed residential builders since 1999. Unlike most Canadian provinces where warranty coverage is voluntary or varies by builder, BC operates one of the strongest new home warranty regimes in North America.
The law was a direct legislative response to BC's catastrophic leaky condo crisis of the 1980s and 1990s, which caused an estimated $1.5–4 billion in building envelope damage across the Lower Mainland and left thousands of strata owners facing unaffordable special levies. The HPO was created to ensure future new home buyers would have financial protection against defective construction.
Every licensed residential builder in BC must register their homes with an HPO-approved warranty provider before breaking ground. Building without registration is illegal, and an unregistered home cannot be legally occupied. As a realtor, you should confirm warranty registration on every new construction transaction — regardless of whether you represent the buyer or seller.
HPO-Approved Warranty Providers (2026)
BC Housing maintains a list of approved warranty providers. The major providers operating in BC include:
| Provider | Notes |
|---|---|
| National Home Warranty (NHW) | BC's largest provider; widely used by volume builders |
| Travelers Canada | Used by many custom and semi-custom builders |
| Pacific Home Warranty | Common in Fraser Valley and Vancouver Island |
| Warranty Solutions Inc. | Boutique builders and single-family custom homes |
| Aviva Canada | Commercial warranty arm for select builders |
The warranty provider is listed in the new home's Certificate of Home Warranty Insurance. For presale strata units, the warranty provider and coverage details must be disclosed in Part 2 of the developer's disclosure statement under REDMA.
The 2-5-10 Warranty: Year-by-Year Coverage Breakdown
The "2-5-10" shorthand refers to three overlapping warranty periods that each cover different components of the new home. Understanding what each year covers is essential for advising buyer clients on what protection they actually have.
| Period | What's Covered | Key Exclusions |
|---|---|---|
| Year 1 (Materials & Labour) | Defects in materials and labour: poor workmanship, cosmetic defects, fixtures that fail to function, improper installation of flooring, tile, drywall, painting | Normal wear and tear, damage from misuse, cosmetic imperfections noted at possession |
| Year 2 (Mechanical Systems) | Defects in mechanical, electrical, and plumbing delivery and distribution systems: HVAC, plumbing, electrical panels, ventilation ducts | Appliances (covered by manufacturer warranty), light fixtures, owner-modified systems |
| Years 1–5 (Building Envelope) | Water penetration through the building envelope: siding, roofing, windows, exterior doors, flashing, waterproofing, caulking, and connections between systems | Damage caused by owner alterations, failure to maintain caulking/seals, improper landscaping that affects drainage |
| Years 1–10 (Structure) | Structural defects that affect load-bearing elements: foundation, framing, beams, columns — defects that make the structure unsafe or unlivable | Damage caused by earthquakes beyond code design parameters, damage from floods, owner modifications to structural elements |
⚠️ Coverage Limits (2026)
Warranty coverage is not unlimited. Maximum coverage amounts under BC's regulations: $200,000 per home for each warranty category, or the original purchase price, whichever is less. For strata buildings, the building envelope and structural limits apply to the whole building, not each unit individually. Always review the actual warranty certificate for the specific coverage limits — they can vary by warranty provider and coverage tier.
Strata-Specific New Home Warranty Rules
New strata developments have a split warranty structure that differs significantly from single-family homes. Understanding this split is critical when advising strata presale buyers and when listing newer strata resales.
How Strata Warranty Is Split
| Warranty Type | Who Holds It | Who Can Claim |
|---|---|---|
| 2-year materials & labour (unit interior) | Individual owner | Individual owner |
| 2-year mechanical (unit plumbing, HVAC) | Individual owner | Individual owner |
| 5-year building envelope (whole building) | Strata corporation | Strata council (on behalf of all owners) |
| 10-year structural (whole building) | Strata corporation | Strata council (on behalf of all owners) |
This split has practical consequences for buyers of strata resales. A buyer who purchases a 3-year-old strata unit:
- Has no remaining 2-year workmanship or mechanical warranty on their unit (it expired with the original owner)
- Benefits from the strata corporation's remaining 2 years of building envelope warranty (until year 5)
- Benefits from the strata corporation's remaining 7 years of structural warranty
Before advising a buyer on their warranty protection, review the Form B and meeting minutes to determine: (a) whether any warranty claims have been filed, (b) whether warranty claims have been settled and what work was done, and (c) whether there are known defects that the strata has not yet claimed under warranty.
Strata Warranty Deficiencies List
At the end of construction, a licensed building envelope professional prepares a Deficiencies Listfor the strata. This list records all outstanding deficiencies the developer must remedy under the warranty. Buyers should request this list and the developer's responses as part of strata document review — outstanding deficiencies on an older complex can signal that remediation has stalled.
Warranty Transfer on Resale
One of BC's most buyer-friendly warranty features is automatic transfer. Under the HPA, the remaining warranty on a new home transfers to subsequent purchasers within the original warranty periods — without any action required by the seller. There is no warranty transfer fee, no application, and no seller consent required.
Warranty Transfer: What Transfers and What Doesn't
| Item | Transfers? | Notes |
|---|---|---|
| Remaining building envelope warranty | ✅ Yes | Automatic — measured from original occupancy date |
| Remaining structural warranty | ✅ Yes | Automatic — measured from original occupancy date |
| 2-year workmanship warranty (if unexpired) | ✅ Yes | Rare — only if home sells within first 2 years |
| Appliance manufacturer warranties | ⚠️ Sometimes | Varies by manufacturer — some require transfer registration |
| Builder's goodwill repairs beyond warranty | ❌ No | Informal builder goodwill doesn't transfer |
| Warranty claim settlements already paid | ❌ No | Settled claims are closed — new buyer gets fresh start on remaining coverage |
As a listing agent for a newer home, the remaining warranty is a marketable feature. Calculate exactly how many years of envelope and structural warranty remain and include it in the property description. A home with 4 years of building envelope warranty remaining is meaningfully more attractive to buyers than one where it has expired.
What Voids or Limits Warranty Coverage
Several actions by homeowners can void or reduce warranty coverage. Advising buyer clients on maintenance obligations — and warning them before they make alterations — is part of good new construction representation.
Common Coverage Voidances
- Unauthorized building envelope work:Adding windows, doors, skylights, or penetrations without the warranty provider's consent can void the 5-year building envelope warranty on the affected area. This includes DIY caulking replacements done improperly.
- Failure to maintain:Warranty providers require homeowners to follow the builder's maintenance manual — typically inspecting and re-caulking annually, cleaning gutters, maintaining grade away from the foundation. Documented failure to maintain is the most common defence raised by warranty providers against claims.
- Structural modifications: Removing walls, adding load-bearing elements, or installing non-structural elements that affect load paths can void structural coverage.
- Delayed reporting: Most warranty providers require defects to be reported promptly upon discovery. Waiting until the warranty period is nearly expired — especially with evidence that the defect was known earlier — can limit recovery.
- Secondary suites added post-construction: A suite added by the homeowner after occupancy is not covered. If a buyer is purchasing a home with a suite the previous owner added, that suite has no warranty coverage.
Owner Builder Homes: The Warranty Gap
BC law allows individuals to build their own home without a builder's licence — called an owner builder. However, owner builder homes are explicitly exempt from the mandatory 2-5-10 warranty requirement. An owner builder home has:
- No mandatory third-party warranty
- An owner builder disclosure notice registered on title (via a caveat)
- A 10-year prohibition on the owner builder selling the home (to prevent flipping warranty-free homes)
🚨 Owner Builder Warning
When you search title on a newer home, check for an owner builder disclosure notice. If present, the home has no mandatory new home warranty. The owner builder can choose to purchase voluntary warranty coverage, but many do not. A buyer of an owner builder home relies entirely on inspections, title insurance, and any voluntary warranty the builder chose to purchase. Always disclose this to buyer clients and recommend they budget for a more comprehensive inspection.
How to Verify Warranty Registration in BC
Always verify warranty registration before or during the subject period on new construction purchases. The verification process:
- HPO Warranty Registration Search: Go to bchousing.org/home-owner/home-warranty→ "Check your warranty." Search by civic address or PID. The search returns the warranty provider, coverage start date, and coverage type.
- Builder Registry Check: Confirm the builder is currently licensed at the HPO Builder Registry. An unlicensed builder cannot legally build new homes in BC — this is a red flag regardless of the transaction stage.
- Certificate of Home Warranty Insurance: Request this document from the seller or their lawyer. It identifies the warranty provider, policy number, and coverage commencement date.
- Presale disclosure statement: For presale units, Part 2 of the REDMA disclosure statement must identify the warranty provider and coverage details.
- Strata Form B: For strata resales, the Form B should identify whether any warranty claims are pending or have been made against the strata.
Making a Warranty Claim: The Process
When a buyer client discovers a defect during the warranty period, the claim process involves multiple steps:
| Step | Action | Timeframe |
|---|---|---|
| 1. Document the defect | Photograph, video, and write a dated description of the defect | Immediately on discovery |
| 2. Notify the builder | Written notice to the builder (email preferred for documentation) | Promptly — before contacting warranty provider |
| 3. Builder assessment period | Builder has a right to inspect and remedy at their cost first | Typically 30 days to respond |
| 4. File with warranty provider | If builder refuses or fails to remedy, file claim with warranty provider | Within warranty period; sooner is better |
| 5. Warranty inspection | Warranty provider sends inspector to assess claim validity | Varies by provider — 2–6 weeks |
| 6. Resolution or dispute | Covered claims: repair or compensation. Disputed claims: conciliation via BC Housing | Resolution in 60–180 days for straightforward claims |
BC Housing provides a warranty conciliation servicefor homeowners and warranty providers who cannot agree on whether a defect is covered. The conciliator's decision is binding on the warranty provider but not on the homeowner — so a homeowner can accept the conciliator's ruling or escalate to the BC Civil Resolution Tribunal or courts.
Presale Purchases: Warranty Considerations
Presale buyers are in a unique position — they're purchasing warranty coverage that doesn't activate until the building is complete and they take occupancy. Key considerations:
- Warranty period starts at occupancy permit, not contract date. A 2019 presale contract that completes in 2022 means the warranty runs from 2022, not 2019.
- Verify the warranty provider is still solvent at completion. If a warranty provider becomes insolvent, BC Housing maintains a Homowner Protection Fund as a backstop — but coverage from the fund is more limited than from a licensed provider.
- Assignment purchasers get the same warranty as original buyers. If your client purchases a presale assignment, they step into the original buyer's shoes for warranty purposes — the warranty period runs from the original occupancy, not the assignment date.
- Interim occupancy in strata doesn't trigger warranty start. The warranty clock starts from the date of the occupancy permit for the building (or the homeowner's unit if phased), not from interim occupancy.

Listing Agent Considerations for Newer Homes
When listing a home that still has active warranty coverage, your marketing should highlight the remaining warranty. Buyers pay a premium for protection — and many buyers don't realize that BC warranty coverage transfers automatically.
Marketing the Warranty
- Include "X years of building envelope warranty remaining" in the MLS description. Be specific — "3 years remaining" is more compelling than "new home warranty."
- Prepare a one-page warranty summary for buyers showing coverage period, provider, and what's covered. Attach to the disclosure package.
- Note the warranty provider and policy number in the Schedule A disclosures so buyers know exactly how to contact the provider.
Disclosure Obligations
Known defects that were remediated under warranty must be disclosed. If the seller filed a warranty claim for water ingress and the builder repaired the flashing, that history is material information. The buyer's insurer and future warranty provider will have records of prior claims — non-disclosure creates misrepresentation risk.
Client Consultation Script
Script: When a buyer is considering a 4-year-old new construction home
"This home is 4 years old, which means the 2-year workmanship and mechanical warranty on the interior systems has expired. But BC law requires the 5-year building envelope warranty — that's the protection against water getting in through the siding, windows, or roof — to run for 5 years from the original occupancy. So you have about one year of envelope warranty remaining. More importantly, the 10-year structural warranty — the foundation, framing, and load-bearing structure — runs until the home is 10 years old, so you have 6 years of structural protection left. These transfer automatically to you at purchase. I'll verify the exact coverage with BC Housing's warranty registry as part of our due diligence."
Frequently Asked Questions
Does the 2-5-10 new home warranty transfer to a new buyer on resale?
Yes. BC's new home warranty under the Homeowner Protection Act automatically transfers with the home to subsequent owners within the original warranty periods. A resale buyer who purchases a 3-year-old home still receives the remaining 2 years of building envelope warranty and 7 years of structural warranty. The transferability is one of the most buyer-friendly features of the BC warranty regime — unlike manufacturer warranties, no action by the seller is required to effect the transfer.
What voids a BC new home warranty?
The most common events that void or limit BC new home warranty coverage include: owner-performed work that damages a warranted system (especially envelope work), failure to maintain the home in accordance with the builder's maintenance manual, modifications to the building envelope without warranty provider consent, and failing to report a defect promptly. Secondary suites and laneway homes added after original construction are not covered unless separately warranted. Commercial use of a residential unit may also affect coverage.
How do I verify a BC builder's warranty registration?
Check the BC Housing Owner Builder Registry and the Homeowner Protection Office (HPO) warranty registration at bchousing.org. Every licensed residential builder in BC must register their new home warranty with an approved warranty provider before construction begins. You can search by civic address, PID, or builder name. The warranty coverage document (Part 2 of the Disclosure Statement for presales) must also list the warranty provider and coverage details.
What is the difference between the building envelope warranty and the structural warranty?
The building envelope warranty (5 years) covers the systems that protect the home from water ingress: siding, windows, doors, flashing, roofing, and caulking. The structural warranty (10 years) covers load-bearing elements — foundation, framing, beams, and columns — against defects that make the building structurally unsafe. Building envelope defects are the most frequently claimed warranty item in BC, particularly in the Lower Mainland where rainfall and construction practices have historically led to significant leaky condo losses.
Does the 2-5-10 warranty apply to strata units?
Yes, but with a split structure. The warranty for individual strata units covers interior workmanship and materials for 2 years and mechanical systems for 2 years. The building envelope and structural warranties (5 and 10 years) belong to the strata corporation, not individual owners — so the strata council has standing to make those claims, not individual unit owners. Buyers of strata units should ask the strata council whether any envelope or structural warranty claims are active or have been settled.
