Alberta New Home Warranty: What the 1-2-5-10 Coverage Actually Includes

Buying a new build in Alberta carries a layer of consumer protection that resale properties simply don't have. Alberta's New Home Buyer Protection Act mandates warranty coverage on every home built since February 1, 2014 — and builders cannot legally opt out, disclaim it in contracts, or transfer the risk to the buyer.

Understanding what's covered, for how long, and what the limits are prevents the single most common mistake new construction buyers make: assuming "it's new, so it's covered" without verifying what the warranty actually says.

Why the Warranty Exists

Before mandatory warranty legislation, buyers of newly built Alberta homes had recourse only through the courts if a builder defected on quality. Litigation was slow, expensive, and often fruitless by the time a builder had dissolved or moved on to new projects. The Act shifted the liability framework: builders must be licensed and must carry registered warranty coverage before a construction permit is issued. No permit, no licence — no sale.

The warranty travels with the title of the property, not the original purchaser. If a builder sells a home, that buyer sells it within the coverage period, and the new buyer discovers a covered defect, the warranty coverage transfers automatically. This is a meaningful protection for buyers purchasing near-new resale homes that are still within the original warranty window.

The Four Coverage Tiers

The Act establishes four distinct tiers, commonly referenced as the 1-2-5-10 warranty:

1 Year: Labour and Materials

The first year covers defects in the cosmetic and finishing components of the home. This includes flooring installation, drywall application, paint, tile work, cabinetry, trim, baseboards, and similar finishes.

This tier has the lowest stakes — cosmetic defects are visible early and relatively inexpensive to repair. The one-year window is intentionally short because these defects are immediately observable on move-in.

2 Years: Delivery and Distribution Systems

Year two extends coverage to the mechanical systems that deliver utilities throughout the home: plumbing, electrical wiring, heating and cooling systems, and ventilation (HVAC). These systems are less visible than cosmetic finishes, and failures can take time to manifest under normal operating conditions.

A furnace that fails in the second winter, plumbing connections that develop leaks under sustained water pressure, or electrical circuits that develop faults — these are the types of defects this tier is designed to catch.

5 Years: Building Envelope

This is the most financially significant tier for Alberta buyers. The building envelope is the barrier that separates the conditioned interior of the home from the exterior environment — the roof structure, exterior walls, windows, doors, and exterior cladding.

Alberta's climate creates severe stress on building envelopes. Temperature differentials between -40°C winters and +30°C summers, combined with significant freeze-thaw cycles, put chronic pressure on seals, membranes, and cladding materials. Failures in the building envelope allow water penetration, which causes interior structural damage, mould, and insulation degradation — repairs that can run into tens of thousands of dollars.

The five-year coverage period reflects how long it typically takes for latent envelope defects to manifest under real weather conditions. Some builders offer an optional extension to seven years on the building envelope, which is worth requesting in negotiations on new construction contracts.

10 Years: Structural Integrity

The ten-year tier covers the load-bearing skeleton of the home: foundation walls, footings, load-bearing beams, floor systems, and roof trusses. These are the components whose failure would render the home structurally unsafe or uninhabitable.

Structural defects are rare, but when they occur — typically in foundations — the remediation costs are catastrophic. The ten-year window provides meaningful long-term protection for the highest-stakes risks.

Coverage Limits

The warranty is not unlimited. Statutory coverage caps are:

• Single-family homes: $265,000 per home
• Multi-family condominium units: $130,000 per unit

These caps cover the repair cost of covered defects. They do not represent the total value of the home. For most cosmetic or mechanical defects, the cap is irrelevant — the repair cost sits well below the threshold. For major structural or building envelope failures, the cap can come into play on larger or more complex remediation projects.

The warranty also includes provisions for reasonable living expenses if a covered defect makes the home temporarily uninhabitable during the repair period.

What Builders Cannot Do

The Act explicitly prohibits certain attempts by builders to narrow or disclaim the mandatory coverage:

• Builders cannot contract out of the warranty requirements
• Purchase contracts cannot include clauses that waive or reduce the mandatory coverage periods
• Builders cannot transfer the warranty obligation to a third party without the buyer's consent and proper registration

If a builder's contract includes language that purports to limit your warranty rights below the statutory minimums, that language is void and unenforceable. Your lawyer should flag any such clauses during contract review.

How to Claim Under the Warranty

Coverage is administered by organizations such as the Alberta New Home Warranty Program (ANHWP), National Home Warranty, and other registered warranty providers. Your builder must register the home with one of these providers at the time of construction.

When you take possession, you should receive a warranty certificate identifying your provider, coverage dates, and the claim process. Keep this document.

To make a claim:

1. Document the defect with photos and written description
2. Submit a formal claim in writing to your warranty provider (not just to the builder)
3. The provider investigates and determines if the defect is covered
4. If covered, the builder is directed to repair — if the builder fails to comply, the warranty provider arranges and funds alternative remediation

Do not rely solely on verbal assurances from the builder that they'll "take care of it." Claims submitted through the formal warranty process are enforceable; verbal commitments are not.

New Construction in Calgary and Edmonton: Market Context

In Calgary, new construction is increasingly concentrated in peripheral communities — Airdrie, Cochrane, Chestermere — where land costs allow builders to price detached homes below the Calgary median. In Edmonton, new builds remain available in southwest suburban communities and at competitive price points relative to resale.

The 2025 federal GST rebate for first-time buyers removes the 5% GST on new homes up to $1 million — eliminating up to $50,000 in tax that previously made new construction less competitive against resale on price. Combined with the warranty protection you don't get on a resale home, new construction has become significantly more attractive for first-time buyers in both cities.
