It is mandatory, and it is tiered
Under Alberta's New Home Buyer Protection Act, warranty coverage is required on new homes. Coverage is structured in four tiers, each running from the date of possession:
- 1 year — labour and materials. The broadest tier and the one you will actually use. Defects in workmanship and materials, which in practice means the snag list.
- 2 years — delivery and distribution systems. Heating, electrical, plumbing — the systems that make the house function.
- 5 years — building envelope. The parts that keep water out: roof, exterior walls, windows and their assemblies. Frequently extendable to 10 years for an additional premium.
- 10 years — structural. Load-bearing elements. Rare to claim, expensive when needed.
What it does not cover
Warranty is not a maintenance contract. Commonly excluded: normal wear and tear, damage from your own failure to maintain the home, settling and shrinkage within normal tolerances, landscaping, and anything you or a third party added after possession.
Normal-tolerance settling is the one that generates the most disappointment. New houses move as they dry out, and hairline drywall cracking in the first year is usually considered normal rather than defective.
Why you should still get a pre-possession inspection
Buyers reasonably assume that a warranty plus municipal inspections make a private inspection redundant. It does not. Municipal inspections check code compliance, not finish quality or whether things actually work. The warranty covers defects — but you have to identify and report them, within the deadlines.
An independent inspection before possession produces a documented list while you still have maximum leverage, which is before the builder has your final payment. It is one of the better-value few hundred dollars in the entire transaction.
Keep the paperwork and diarise the dates. The one-year and two-year marks arrive faster than you expect, and a claim submitted after a deadline is simply not a claim.
