What is a Home Warranty Program?
A Home Warranty Program is a form of insurance that protects new homebuyers from defects in workmanship, materials, and major structural components for a set period after purchase.
Why Home Warranty Programs Matter in Real Estate
In Canada, many provinces require builders to enroll new homes in a licensed home warranty program, especially for new construction or pre-construction properties. These programs provide peace of mind to buyers by covering specific defects or issues that arise after occupancy.
Coverage typically includes:- One year for labour and materials
- Two years for systems like plumbing, heating, and electrical
- Seven years for major structural defects
Programs vary by province. In Ontario, for example, Tarion administers the mandatory new home warranty program. In British Columbia, it's overseen by BC Housing. Coverage may also extend to delayed closings and deposit protection.
Understanding a home warranty program helps buyers know what is covered, what’s excluded, and how to file claims if issues emerge. Buyers should keep all documentation, inspection reports, and correspondence related to their home in case warranty service is needed.
Example of a Home Warranty Program?
After moving into a new townhouse in Toronto, a homeowner discovers plumbing leaks. The issue is covered under the two-year warranty, and the builder arranges repairs through Tarion.
