Alberta New Home Warranty: What It Actually Covers and How to Use It
The mandatory warranty program protects Alberta buyers — but builders and warranty providers dispute more claims than you'd expect. Know the coverage periods, the exclusions, and exactly how to navigate a dispute before you need to.
Alberta Is One of the Best-Protected Provinces for New Build Buyers
Alberta's mandatory new home warranty program is among the most comprehensive in Canada. Every new home must be enrolled before possession — no exceptions. But coverage has specific exclusions and timelines that builders frequently use to deny claims. This guide explains what is actually covered, what is not, and how to fight back when a legitimate claim is refused.
How the Alberta New Home Warranty Works
The program is legislated under the New Home Buyer Protection Act — not a voluntary builder offering. Understanding the legal structure changes how you approach a dispute.
The New Home Buyer Protection Act (NHBPA), which came into force in February 2014, requires every new home built in Alberta to be covered by warranty insurance before possession is transferred. A builder who attempts to sell or transfer a home without warranty enrollment faces administrative penalties and cannot legally complete the transaction.
Warranty Providers in Alberta
Alberta uses an approved insurer model. Builders must use a provider licensed by the New Home Buyer Protection Office (NHBPO), the provincial regulator.
Alberta New Home Warranty Program (ANHWP)
The original provider, now part of the Canadian Home Builders' Association Alberta. Well-established claims process. Builder must be a member of CHBA Alberta.
National Home Warranty / NHW
One of the larger private warranty providers operating in Alberta. Used by many mid-to-large volume builders.
Other Licensed Providers
Several other approved insurers operate in Alberta. Confirm your builder's provider at signing — it is disclosed in your purchase agreement and on the warranty certificate you receive at possession.
Your Warranty Certificate
You should receive a warranty certificate at or before possession. This document is essential — it confirms enrollment, identifies the warranty provider, and outlines coverage.
If You Have Not Received a Certificate:
Do not proceed to possession without it. You can verify enrollment at nhbpo.ca — Alberta's New Home Buyer Protection Office maintains a public registry of enrolled homes by address. Search your address before possession day.

The Coverage Timeline: What Is Covered and When
Coverage is tiered across four time periods. The key is understanding exactly what each tier covers and — critically — what it does not.
Year 1 — Labour and Materials Defects
From possession date to 12 months
Year 1 is the broadest coverage period. It covers defects in materials and workmanship — meaning anything that was installed incorrectly or with defective materials. This is the period where most cosmetic and finishing issues must be identified and reported.
Clear Examples of Covered Year-1 Issues:
Year-1 Exclusions Builders Commonly Cite:
The Year-1 Deadline Is Real — Don't Miss It
Most warranty programs require written notice of Year-1 claims before the 12-month anniversary. Missing this deadline typically bars your claim for labour and materials defects. Submit your claim list in writing to the builder and send a copy to your warranty provider at the 11-month mark — not on the last day. Allow time for disputes.
Year 2 — Distribution Systems
From possession date to 24 months
Year 2 coverage extends to defects in your home's major systems — the electrical, plumbing, heating, cooling, and ventilation infrastructure. These are the systems that distribute power, water, heat, and air throughout your home.
What Distribution Systems Includes:
Important: Equipment vs. Systems
The warranty covers defects in the installation and integration of systems — not normal equipment wear or failure unrelated to a defect. A furnace that fails in Year 2 due to a manufacturing defect is typically covered. A furnace that fails because a filter was never changed is not. Keep records of all maintenance.
Still Also Covered in Year 2:
Year 1 labour and materials coverage runs concurrently. If a Year-1 issue was reported in writing before the 12-month deadline, the repair obligation continues into Year 2.
Years 1–5 — Building Envelope
Runs from possession to 60 months (5 years)
The building envelope is everything that separates the interior of your home from the outside environment. Envelope defects are among the most expensive to repair — and the most common source of warranty disputes.
Envelope Components Covered:
Common Builder Defenses Against Envelope Claims:
Water penetration disputes require evidence of where water enters, not just where it appears inside. Professional moisture mapping or an independent inspector report significantly strengthens envelope claims.
Years 1–10 — Major Structural Defects
Runs from possession to 10 years (120 months)
Structural defects are the most serious — and the most narrowly defined — coverage tier. The standard requires proof that a structural defect "causes or is likely to cause structural failure" or makes the home "unfit for habitation." This is a high bar.
What Qualifies as a Major Structural Defect:
What Does NOT Qualify:
Structural claims almost always require a professional structural engineer's report. Retain an independent engineer before submitting a structural warranty claim — a builder's engineer will not be independent.
What Is NOT Covered: The Full Exclusion List
Builders and warranty providers cite exclusions frequently. Know all of them before you file a claim so you can anticipate and counter the arguments you will encounter.
Universal Exclusions (All Tiers)
Normal wear and tear
The definition of 'normal' is contested. Builders classify many defects as normal wear.
Homeowner negligence or misuse
Failure to maintain (clean gutters, change filters, caulk windows) can void claims. Keep maintenance records.
Damage from unauthorized alterations
Any modification you made — a wall removed, a hole drilled, a system altered — voids warranty for affected areas.
Defects known at possession not documented
Issues you saw at the walkthrough and did not record in writing are assumed accepted. Never sign a 'satisfied' walkthrough form without noting every defect.
Insured events (fire, flood, hail, etc.)
These belong under your home insurance. Builders and warranty providers will redirect these claims to your insurer.
Specific Exclusions to Know
Appliances (beyond appliance manufacturer warranty)
Builder-supplied appliances have their own manufacturer warranty (typically 1-5 years). The home warranty does not extend or replace appliance warranties.
Detached structures
Fences, detached garages, sheds, and pergolas are typically excluded unless specifically written into the purchase agreement.
Landscaping and grading (after first year)
Grading issues that cause drainage problems may be Year-1 covered. After that, landscaping is your responsibility.
Cosmetic defects with no functional impact
Minor paint touch-ups, small chips, minor drywall blemishes — if they don't affect function, expect 'cosmetic' arguments.
Secondary suites built by the buyer after possession
Any basement suite or addition you build is your responsibility. Warranty only covers original construction.
Condensation on windows (in most cases)
Interior condensation is typically excluded as a 'normal' humidity issue. Seal failures and moisture infiltration between panes are different — those are defects.
The "Normal Settlement" Argument: What It Means and When to Push Back
"Normal settlement" is the most frequently cited exclusion by builders responding to cracks, gaps, and movement in new homes. New homes do settle — wood framing dries out, concrete shrinks, and ground compacts. But there is a threshold. Here is when "normal settlement" is a legitimate exclusion versus when it is being used to avoid a valid claim:
Typically Normal (Not Covered):
- • Hairline cracks in drywall at corners (under 3mm)
- • Minor nail pops in drywall (a few per room)
- • Small gaps at baseboards from wood shrinkage
- • Minor floor squeaks (first year — builder should address at Year-1 service)
- • Small cracks in concrete basement floors (less than 3mm wide, not structural)
Beyond Normal — Push Back:
- • Cracks wider than 3-5mm or that are growing
- • Cracks that allow water or air infiltration
- • Horizontal foundation cracks (major structural red flag)
- • Stair-step cracks in masonry or brick
- • Differential settlement (one part sinking, others stable)
- • Doors that no longer close due to frame movement
How to File a Warranty Claim: The Complete Process
The warranty claim process has specific steps and deadlines. A procedural misstep can cause a valid claim to be denied on technical grounds.
Document Everything Before You Report
Before contacting anyone, build a complete evidence file. This is the most important step — documentation created before a dispute is far more credible than documentation created during one.
Submit Written Notice to the Builder
You must give the builder written notice of defects and a reasonable opportunity to inspect and repair before escalating to the warranty provider. This is a legal requirement. Verbal reports and show-home conversations do not count.
Always Use Certified Mail or Email With Read Receipt
Send your written warranty notice by registered mail to the builder's registered business address or by email with read receipt to the builder's warranty contact. You need proof of delivery and the date of delivery. Text messages and phone calls are not sufficient documentation. Your notice letter should be specific: list each defect, its location, and the coverage period you believe applies.
What a Proper Warranty Notice Letter Contains:
1. Your name, address, possession date, and warranty certificate number
2. A numbered list of each defect with location, description, and discovery date
3. Which coverage period you believe applies for each item
4. Your request for inspection within a specified timeframe (suggest 14-21 business days)
5. Notice that if not addressed, you will be escalating to the warranty provider
6. Attached: your full photo/video documentation package
Builder Response: What to Watch For
After receiving your notice, the builder should inspect and respond in writing with either an acceptance of each item or a denial with reasons. Here are common builder tactics and how to respond:
Builder Says: "That's normal settlement / normal for new homes"
Your Response: Ask for the specific warranty exclusion clause they are applying. Vague 'normal' claims without reference to specific exclusion language are not valid denials. Request the written exclusion provision.
Builder Says: "Scheduling inspection but never actually coming"
Your Response: Document every missed appointment in writing. If after two missed appointments the builder has not inspected, send a written escalation notice stating you will be contacting the warranty provider within 10 business days.
Builder Says: "Doing partial repairs that don't fix the underlying issue"
Your Response: Never sign any satisfaction or release document for warranty repairs unless you have confirmed the repair actually resolves the defect. A 'repaired' item that fails again is still a warranty claim.
Builder Says: "Claiming your maintenance failures caused the issue"
Your Response: Produce your maintenance records. If you have changed HVAC filters, maintained gutters, and caulked as recommended, document this. The builder must prove maintenance failure caused the defect, not simply assert it.
Builder Says: "Offering a cash payment in exchange for signing a warranty release"
Your Response: Do not sign any release without legal advice. Once you release warranty rights in writing, you cannot later pursue the warranty provider for the same issue. The payment offered is rarely sufficient to cover the actual repair cost.
Escalating to the Warranty Provider
If the builder denies a valid claim, fails to respond within a reasonable time (typically 30-45 days after your written notice), or completes repairs you believe are inadequate, you have the right to file a claim directly with the warranty provider.
What to Submit to the Warranty Provider:
• Copy of your warranty certificate
• Copy of your original written notice to the builder
• Proof of delivery of that notice
• Builder's written response (or documentation of non-response)
• Your full photo and video documentation
• Any independent inspection reports you've obtained
• A timeline of events
The Warranty Provider's Role
The warranty provider sends an independent inspector to assess the defect. If they confirm coverage, they either direct the builder to repair or — if the builder cannot or will not — arrange repairs themselves. This process typically takes 60-120 days from claim submission to resolution for straightforward cases.
Dispute Resolution: When the Provider Denies Your Claim
If the warranty provider denies your claim and you believe the decision is wrong, you have further escalation options. Do not accept a denial as final without reviewing these options.
NHBPO Complaint (Free)
The New Home Buyer Protection Office regulates both builders and warranty providers. Filing a complaint does not resolve your claim but creates an official record and can trigger regulatory review. File at nhbpo.ca or call 1-877-639-5374.
Arbitration (Most Common Path)
Most Alberta warranty programs include a binding arbitration clause. This is faster and less expensive than court — typically 3-6 months and $2,000-$8,000 in arbitration fees. An independent arbitrator reviews evidence and issues a binding decision. This is worth pursuing for claims over $15,000.
Court Action
For significant claims where arbitration is not available or has been exhausted. Alberta's Court of King's Bench handles these matters. Legal costs can be recovered if you win, but the process takes 1-3 years. Consult a construction lawyer before proceeding — many offer free initial consultations.
When to Involve a Lawyer
Any claim over $10,000, any denial involving structural or envelope coverage, or any situation where you are asked to sign a release should involve legal review. Calgary has several construction law firms that handle builder and warranty disputes specifically. An initial consultation ($300-$500) can clarify whether you have grounds to push back and what the realistic outcome of escalation would be.
Critical Deadlines: Your Warranty Calendar
Missing a deadline can permanently bar a valid claim. Mark these dates before you take possession.
| When | What to Do | Why It Matters |
|---|---|---|
| Possession Day | Complete walkthrough, document everything in writing, do not sign "satisfied" without noting all defects | Issues not documented at possession are presumed accepted — hardest to claim later |
| Month 3-6 | Inspect for early settling issues: nail pops, hairline cracks, door alignment, grout separation | Early identification gives maximum time for Year-1 claims |
| Month 11 | Submit your complete Year-1 defect list to builder in writing (certified or email). Copy to warranty provider. | Year-1 claims must be submitted before the 12-month anniversary — do it one month early |
| Month 23 | Inspect and submit any system defects (electrical, plumbing, HVAC) before Year-2 expiry | Year-2 distribution system claims expire at month 24 |
| Month 59 | Inspect exterior thoroughly: stucco, windows, roof, flashing. Submit envelope claims in writing. | Year-5 envelope claims expire at month 60 |
| Years 6-10 | Monitor for structural concerns. Any major cracking, foundation movement, framing issues — document and submit. | Structural warranty runs to 10 years but claims must be filed within a reasonable time of discovery |
Set Calendar Reminders on Possession Day
The day you take possession, set recurring calendar reminders for months 11, 23, and 59. These are the claim submission deadlines for each coverage tier. It sounds simple, but over a decade of homeownership, these dates are easy to miss — and the consequences of missing them are significant.
The Pre-Possession Walkthrough: Your Most Important Warranty Moment
Everything you observe and document at the walkthrough becomes part of your warranty record. Approach it systematically, not casually.
Never Rush a Walkthrough
Builders typically schedule walkthroughs 1-2 hours before you are expected to sign possession documents. This creates time pressure. Do not let it. You are legally entitled to a thorough inspection before taking possession. If the builder is rushing you, tell them directly that you need more time and will not sign until the inspection is complete.
If a defect is significant enough that you are not satisfied with the builder's response, you can refuse possession until it is resolved. This is your legal right under the purchase agreement.

Systematic Room-by-Room Check:
What to Do With the Deficiency Form
The builder's walkthrough form typically has a list of items and a signature line. Before you sign anything, ensure every defect you identified is listed on the form with a specific description. Vague entries like "minor paint" or "small crack" are harder to enforce than "Master bedroom east wall: 2mm hairline crack running 30cm from window corner."
Request a copy of the completed form before you leave. If the builder says they'll email it to you, that is not acceptable — get the physical signed copy at the walkthrough.
If the builder refuses to add items to the deficiency form, note in writing (on the form itself or in a separate email sent immediately after) that you observed additional defects and are reserving your right to claim them under warranty.
