Earlier this year, after several consultations with industry and other stakeholders, Tarion announced a new change to take effect January 1, 2026, to encourage freehold home buyers to register their purchase agreements with Tarion using a simple online process, to help consumers be more informed about the builder’s warranty and support the Home Construction Regulatory Authority (HCRA) in investigating and stopping illegal activity.
Prior to the purchaser registration changes coming into effect on January 1, new home buyers can register their purchase agreements at Tarion.com/RegisterToday
Starting July 14, Tarion is adding a new tool to support this initiative with the launch of a unique Home ID number and new Warranty Information Sheets for all home types. The idea of a unique identification number was created based on feedback and discussions with builders, and the new process was developed in consultation with industry.
These changes will support the homeowner registration process, help educate consumers, identify illegal activity to Tarion, and support the Home Construction Regulatory Authority (HCRA) to investigate and stop illegal activity.
Below is further information on the new Home ID and Warranty Information Sheets.
What is the New Home ID Number?
Starting July 14, the Home ID number will be a unique number tied to each home or unit a builder is approved to sell.
This unique Home ID number is generated through BuilderLink, and will be available at the time of Qualification for Enrolment (QFE) or Enrolment confirmation. The Home ID number will ultimately become the enrolment number that Tarion currently uses when a builder enrolls the home in the warranty program.
This Home ID number will help Tarion to identify any illegal actor who has entered into an agreement with a purchaser - and in partnership with the HCRA - take appropriate action.
We want to thank all those who provided invaluable input over the last year to help develop the new Home ID process.
For more information on the changes and how to generate the Home ID and new Warranty Information Sheets, Tarion has created a technical guide to help you with the new process which you can find on BuilderLink.
New Warranty Information Sheets Required – Starting July 14
As part of this new initiative, Tarion is also introducing new Warranty Information Sheets for purchase agreements signed on or after July 14, 2025. These new Warranty Information Sheets will include information on the importance of a purchaser registering their purchase agreement, as well as the unique Home ID number and purchaser’s registration code.
This registration code is used by the purchaser to register their purchase agreement with Tarion as part of the new process.
Warranty Information Sheets that apply to homes purchased prior to July 14, 2025, can be found on BuilderLink.
