New Build In Alberta · Homeowners
Every new home built in Alberta since 2014 comes with mandatory warranty coverage under the New Home Buyer Protection Act. This guide, informed by an interview with the Alberta New Home Warranty Program, covers what each window protects, who pays for it, what transfers when you sell, and the maintenance that keeps coverage valid.
What does new home warranty cover in Alberta?
New home warranty in Alberta is mandatory and legislated under the Alberta New Home Buyer Protection Act (2014). The builder purchases the policy from a licensed warranty provider before construction begins. Coverage lasts ten years and is layered across four windows: one year for materials and labour, two years for delivery and distribution systems (electrical, heating, plumbing), five years for the building envelope (extendable to seven), and ten years for structural defects. The policy transfers to any subsequent owner when the home is sold. Warranty providers work for the consumer, not the builder.
01 The Basics
New home warranty first appeared in Alberta in 1974 as a voluntary program. Builders offered it to buyers as a signal of quality. Alberta was the first province to formalize the model. In February 2014, the province made the coverage mandatory through the Alberta New Home Buyer Protection Act. Every builder is now required to carry a warranty policy with a licensed provider before pulling a permit. The act was designed to protect consumers without materially raising the price of a new home.
There are four licensed warranty providers in Alberta. The builder chooses one. You inherit that choice when you take possession, and your relationship for the length of coverage is with the warranty provider, not the builder. This is important: the provider works for you. Providers hold builders accountable using indemnities and site inspections, ensuring builder competency and giving the consumer a real second line of defence.
Coverage on your specific home starts the day after possession. For condominium buildings, coverage on the common property starts when the first unit sells; coverage on each individual unit starts the day after that unit’s possession. That first day of ownership without coverage exists so the buyer and builder can resolve any obvious issues directly before the warranty period begins.
02 Coverage Windows
Each window covers a different category of defect and closes at a different time. Know which window you are in before you file a claim.
Materials and labour Coverage period: 1 year from possession
The comprehensive workmanship layer. Covers cosmetic and finishing defects: baseboards, flooring, trim, paint, drywall, cabinetry, and other visible components. Most first-year claims fall here. Common items include separation of materials as the house settles, paint touch-ups at seams, and adjustments to interior doors and hardware. Document issues as you find them and submit claims before the anniversary date.
Delivery and distribution systems Coverage period: 2 years from possession
The mechanical systems layer. Covers the electrical system, heating (furnace, HRV, ducting), and plumbing (supply lines, drains, fixtures). Common second-year claims: flickering LED lights, water leaks at fittings, noise in the plumbing system, HRV imbalances, and furnace or hot-water-tank performance issues. All mechanical systems should be operating properly at the two-year anniversary; that is the last window to catch and file distribution-system defects.
Building envelope Coverage period: 5 years, extendable to 7
The weather barrier layer. Covers the roof, exterior walls, windows, doors, and any component separating conditioned interior space from the outside. Envelope defects usually show up as water penetration or air leakage. Some builders offer a two-year extension to seven years for an additional premium; ask your builder or check your policy documents to confirm whether your specific coverage is extended.
Structural defects Coverage period: 10 years from possession
The frame and foundation layer. Covers structural defects that compromise the load-bearing capacity of the home or render it unfit to live in. This is the longest window because structural issues can take years to surface. Structural claims are rare but consequential; when they happen, the ten-year coverage is what turns a catastrophic repair into a managed one.
03 Buying And Selling
Warranty coverage is tied to the home, not the original buyer. When a home under warranty is sold, the remaining coverage transfers to the new owner. The new owner contacts the warranty provider, submits the transfer of title, and receives a new policy in their name. There is no gap in coverage.
For the buyer, a home still under warranty comes with two concrete benefits. First, the remaining coverage itself: any defect that shows up before the applicable window closes is the warranty provider’s problem, not yours. Second, the claim history: every registered claim on the home is on file with the provider. A clean history is a data point of confidence. A history with resolved issues shows what was fixed, when, and how. Both are more useful than any seller disclosure.
For the seller, remaining warranty coverage is a legitimate value driver. Buyers pay more for less risk. Surface the remaining coverage window and any claim history in your listing description and provide the transfer instructions to the buyer’s lawyer before closing.
How to check if a home is still under warranty. Two paths. If you know the provider, contact them directly with the property address. If you do not, use the Alberta government public registry at homewarranty.alberta.ca. Search by address or builder to see whether warranty exists, who the provider is, and when coverage started.
Warranty coverage does not replace a home inspection. Even on a new build, an independent inspector provides a second set of expert eyes on the construction and catches items that might otherwise sit undocumented until the coverage window closes.
04 Your Responsibilities
Warranty coverage is not a substitute for maintenance. Claims can be denied when the defect was caused or worsened by owner neglect. The list below is not exhaustive, but these are the items new homeowners in Alberta miss most often.
Mechanical systems. Change your furnace filter every three to six months on the schedule the manufacturer specifies. Change your humidifier filter once or twice a year. Clean the HRV filters regularly; an unbalanced HRV degrades your ventilation and drives up humidity. Have your furnace serviced annually by a licensed technician.
Outdoor grading and surface water. Your home was graded so water flows away from the foundation. Grading settles. Walk the perimeter every spring and after major weather. If the slope has gone flat or is pooling near the foundation, remove the sod, add compactable clay to restore the pitch, and replace the sod with fresh soil mix. This one habit prevents the majority of basement moisture claims.
Indoor humidity. New homes are built tight for energy performance. Building code allows the home to operate at up to 35% relative humidity. Above that, moisture accumulates and creates conditions for mould. Run your bathroom fans through and after showers, use HRV systems on their recommended settings, and keep every mechanical filter clean. Excess indoor humidity is the leading cause of premature envelope claims that owners cannot recover on.
Common Questions
No. New home warranty is consumer protection first and insurance-of-product second. Three practical differences: the builder purchases warranty (not the homeowner); warranty is a one-time cost baked into the build (not an annual premium); and warranty cannot be cancelled once it has started. Home insurance still applies for perils like fire, theft, and water damage from external sources. Warranty covers construction defects. You need both.
No. Home warranty providers are private companies licensed by the province. They existed in Alberta before the 2014 legislation made warranty mandatory and continue to operate independently. The government sets the coverage floor and licenses the providers; the providers deliver the policy and handle claims.
The buyer. Builders are legislated to purchase warranty on every new home. The warranty provider sells the product to the builder but is accountable to the consumer for the length of coverage. Providers hold builders accountable through indemnities and inspections, ensuring builder competency and giving the homeowner a genuine third-party advocate.
The day after possession, when the keys transfer from the builder to the homeowner. It can also key off transfer of title or the issuance of an occupancy permit, depending on the policy. For a condominium unit, coverage on the common property begins when the first unit sells; coverage on your individual unit begins the day after you take possession.
All remaining coverage transfers to the new owner. The new owner contacts the warranty provider, submits the transfer of title, and receives a new policy issued in their name. They also gain access to the claim history on the home, care and maintenance information from the provider, and remaining coverage across all four windows.
Yes. Warranty covers defects that meet the policy definition. An independent inspection is a valuable second set of expert eyes that catches items you would otherwise discover months later, sometimes after the applicable coverage window has closed. The one-time cost of an inspection is minor compared to the value of documenting an issue while it is still eligible for a claim.
Two options. Contact the warranty provider directly if you know who it is. If you do not, search the Alberta public registry at homewarranty.alberta.ca by property address or builder to see whether warranty exists, who the provider is, and the commencement date.
Yes. A claim can be denied when the defect was caused or worsened by owner neglect. The most common examples are envelope claims driven by uncontrolled indoor humidity, mechanical claims driven by skipped furnace servicing or unchanged filters, and foundation-adjacent claims driven by settled grading that pooled water at the perimeter. Manufacturer maintenance documents provided at possession set the standard the warranty provider will hold you to.
