Your Newly Constructed Home Comes with a 7 Year Warranty Provided by the Builder and Backed by Tarion

A common misconception is that everything is covered for 7 Years. On the contrary, the 7 Year Warranty has very limited coverage. The One Year Tarion Warranty Inspection is the most comprehensive one, as most defects are not covered after the one year has passed and any repairs will be at your own expense.

These are the three main levels of your Tarion Warranty

Your PDI (Pre-Delivery Inspection) and 30 Day Inspection

These are two very important stages in your Tarion Warranty.

A pre-delivery inspection (PDI) is mandatory for all new homes enrolled with Tarion. The main purpose of the PDI is to document the condition of the home prior to possession or occupancy. As a general rule, the inspection may take up to one hour for every 1,000 square feet.

Our inspection process is very thorough and goes over and above cosmetic issues. We will assign two inspectors for the PDI so that there is enough time to complete it within the time frame required. Ask your builder if they require you to complete Tarion’s Appointment of Designate form.

The 30 Day Inspection gives you the opportunity to report any issues that occur during the first 30 days of occupancy and use of the systems of the house.

Seven Year Warranty

Your home’s Seven-year warranty covers major structural defects (MSD) and begins on the date you take possession of the home, and ends on the seventh anniversary of that date. For example, if your home’s date of possession is October 23, 2005, the Seven-year MSD warranty begins on October 23, 2005 and remains in effect until and including October 23, 2012.

A major structural defect is defined in the Ontario New Home Warranties Plan Act as:

In respect of a post-June 30, 2012 home, any defect in work or materials in respect of a building, including a crack, distortion or displacement of a structural load-bearing element of the building, if it,

(i) results in failure of a structural load-bearing element of the building.

(ii) materially and adversely affects the ability of a structural load-bearing element of the building to carry, bear and resist applicable structural loads for the usual and ordinary service life of the element.

(iii) materially and adversely affects the use of a significant portion of the building for usual and ordinary purposes of a residential dwelling and having regard to any specific use provisions set out in the purchase agreement for the home.

The Seven-year MSD warranty includes significant damage due to soil movement, major cracks in basement walls, collapse or serious distortion of joints or roof structure and chemical failure of materials. In addition to the general exclusions, the Seven-year MSD warranty specifically excludes: dampness not arising from failure of a load-bearing portion of the building; damage to drains or services; and damage to finishes.

Radon and Your Warranty

Radon is an invisible, odorless, naturally occurring gas found in soil. It seeps into homes through cracks in floors, walls and foundations – access points mainly found in basements.  Since radon is naturally occurring, it’s found in just about every home.

However, high concentrations of radon in a home may pose health risks.  According to Health Canada, people exposed to radon levels in excess of 200 Becquerels per cubic metre (becquerels are a unit of measurement for radioactivity) over long periods of time have a higher risk of developing cancer.

Warranty Coverage

For all purchase agreements signed on or after February 1, 2021, there is up to $50,000 coverage for warranted damage caused environmentally harmful substances or hazards. This coverage includes mitigation of excessive levels of radon. The warranty covers remediation of radon gas in excess of 200 Becquerels per cubic metre and coverage lasts for up to seven years.
