What is the New Home Buyer Protection Act in Alberta?

Alberta's New Home Buyer Protection Act (NHBPA) is provincial legislation that requires all new homes built in Alberta to be covered by mandatory home warranty insurance — protecting buyers from defects in workmanship, materials, and structure for up to 10 years.

This Act came into force in 2014 and fundamentally changed how new home construction works in Alberta. Before the NHBPA, home warranty was optional, leaving many buyers with little recourse when serious defects emerged after closing. Today, any builder constructing a new home in Alberta must be registered with an approved warranty provider before breaking ground — no exceptions.

Who It Applies To

The NHBPA covers new homes including single-family houses, semi-detached homes, duplexes, townhouses, and condominiums. The builder must be registered with the Alberta New Home Warranty Program (ANHWP) or another approved warranty provider before construction begins. You can verify a builder's registration status at anhwp.com — this is one of the most important checks you can do before signing a purchase contract. Builders who construct new homes without registration face significant penalties under the Act.

The 1-2-5-10 Warranty Coverage

The NHBPA mandates what's commonly called 1-2-5-10 warranty coverage, structured in four tiers:

• 1 year — Labour and materials defects (finishes, fixtures, workmanship)
• 2 years — Delivery and distribution systems, including electrical, plumbing, HVAC, and gas lines
• 5 years — Building envelope defects, including water penetration through the roof, exterior walls, windows, and doors
• 10 years — Major structural defects affecting load-bearing components and the foundation

This tiered structure means your protection doesn't expire all at once — your foundation and structural components are covered for a full decade, which matters enormously given Calgary's expansive clay soils and the foundation movement that can develop over time.

What It Doesn't Cover

The NHBPA applies to new home construction only. If you're adding a secondary suite, garage suite, or backyard suite to an existing home, builder registration is not required — but all standard permits and inspections absolutely still are. Major renovations to existing homes are also outside the scope of the Act, which is why due diligence on your renovation contractor matters so much.

Practical Advice for Calgary Buyers

If you're purchasing a newly built home in Calgary or the surrounding communities — Airdrie, Cochrane, Okotoks, Chestermere — always confirm your builder's registration status before signing anything. Ask which warranty provider is covering your home, review the warranty certificate carefully, and understand the claims process before you need it. Approved warranty providers in Alberta include the Alberta New Home Warranty Program, National Home Warranty, Progressive Home Warranty, and WBI Home Warranty.

If you're buying a new home and have concerns about builder registration or warranty coverage, consult a real estate lawyer familiar with Alberta's NHBPA before closing.
