One of the perceived advantages of buying a newly built home is the warranty coverage that comes with it. Unlike a resale purchase where the buyer inherits whatever condition the home is in at the time of sale, a new home is covered by a statutory warranty that provides a defined level of protection for a defined period after closing. Most buyers believe this protection is comprehensive. In practice, it is specific, limited, and comes with important exclusions and processes that buyers need to understand before they encounter a problem.
Realtors who can speak knowledgeably about new home warranty coverage provide a genuine service that helps buyers make informed decisions and avoid the frustration of a warranty claim that is denied for reasons they did not anticipate.
The Tarion Warranty in Ontario: The Foundation of New Home Protection
In Ontario, new home warranty protection is administered by Tarion Warranty Corporation. Every new home built by a registered builder in Ontario is covered by a Tarion warranty that provides three tiers of protection covering different types of defects over different time periods.
The one-year warranty covers defects in work and materials, violations of the Ontario Building Code, and unauthorized substitutions. The two-year warranty covers water penetration through the building envelope, defects in work or materials in the electrical, plumbing, and heating systems, defects in work or materials that result in the detachment or failure of exterior cladding, and violations of the Ontario Building Code that affect health and safety. The seven-year warranty covers major structural defects, meaning defects that affect the load-bearing portion of the building or significantly impair the use of the building as a home.
Similar mandatory warranty programs exist in most other Canadian provinces. British Columbia has the BC New Home Warranty program administered by approved warranty providers. Alberta has mandatory new home warranty coverage under the New Home Buyer Protection Act. Saskatchewan, Manitoba, Quebec, and the Atlantic provinces all have their own statutory requirements, though the specifics vary.
What Is Not Covered: The Exclusions That Surprise Buyers
Understanding what a new home warranty does not cover is as important as understanding what it does. Common exclusions under the Tarion framework and similar provincial programs include: cosmetic defects that do not affect the function or structural integrity of the home, damage caused by the homeowner normal use or lack of proper maintenance, secondary damage caused by covered defects where the homeowner did not take reasonable steps to mitigate, defects in items that the homeowner provided or had installed independently, and damage resulting from negligent use or unauthorized alterations by the homeowner.
The definition of what qualifies as a defect versus normal wear, settlement, or cosmetic variation can be genuinely contested, and the threshold for what constitutes a defect eligible for warranty repair is higher than many buyers expect. Hairline cracks in drywall from normal settlement, for example, are generally not covered as defects. Water infiltration that occurs because the homeowner modified the grading around the foundation may not be covered if the modification contributed to the problem.
The PDI: Pre-Delivery Inspection
One of the most important steps in a new home purchase under the Tarion framework is the Pre-Delivery Inspection, or PDI. This is a formal inspection of the home conducted before the buyer takes possession, in which the builder walks the buyer through the home and notes any existing defects, incomplete items, or damage on a PDI form. Items noted on the PDI form become the builder responsibility to address.
Buyers frequently approach the PDI as a celebratory walkthrough of their new home rather than as the serious inspection opportunity it is. A buyer who does not carefully inspect every element of the home during the PDI and document every observed deficiency gives up the protection that the PDI process is designed to provide. As a realtor, advise your new construction clients to approach the PDI with the same attention they would bring to any other property inspection, ideally with a third-party inspector present who knows what to look for in new construction.
The 30-Day and Year-End Reporting Process
Under the Tarion system, buyers have defined windows within which to report warranty issues. The first 30 days after possession are for reporting defects discovered immediately after moving in. The year-end reporting period, in the 11th month of the first year of possession, is the opportunity to report any additional defects discovered during the first year of living in the home. Missing these reporting windows can compromise the buyer ability to have warranty claims addressed.
Advise your new construction clients of these reporting timelines at closing and again as each deadline approaches. A homeowner who discovers a problem in month eight and assumes they can report it whenever is convenient may find the reporting window has closed by the time they get around to it.
