Tarion warranty 101 for new home developers
What every Ontario developer needs to know about Tarion enrollment, deposit insurance, and the seven-year warranty.
Tarion is Ontario's mandatory new home warranty program
Every developer building new homes in Ontario must enroll the units, and the buyer's deposit is protected up to the statutory limit. Since February 1, 2021, the regulatory landscape has been split: the Home Construction Regulatory Authority (HCRA) licenses builders and vendors under the New Home Construction Licensing Act, 2017, while Tarion administers the warranty under the Ontario New Home Warranties Plan Act (ONHWPA). Before 2021 Tarion did both, and the split followed Justice Cunningham's 2016 independent review - practically, this means a developer today deals with HCRA for licensing, conduct, and disciplinary matters, and with Tarion for enrollment, deposit protection, and warranty claims.
The Tarion warranty covers three time horizons
The one-year warranty requires the home to be constructed in a workman-like manner and free from defects in material, protects against Ontario Building Code violations and unauthorized substitutions, and requires the home to be fit for habitation. The two-year warranty extends to water penetration through basement or foundation walls, defects causing detachment, displacement, or deterioration of exterior cladding, defects in the electrical, plumbing, and heating delivery and distribution systems, and OBC violations that affect health and safety. The seven-year warranty covers major structural defects - load-bearing element failures that materially affect the home's use or structural integrity - and excludes elevating devices, dampness not caused by structural failure, owner negligence, flood damage, and acts of civil or military authorities.
Enrollment is the developer's responsibility before construction begins. Every unit must be enrolled with Tarion, and the home must be sold by an HCRA-licensed vendor and built by an HCRA-licensed builder for warranty coverage to apply - these can be the same entity or different entities, but both licences are required, and a buyer who walks into a presentation centre run by an unlicensed seller is buying without statutory warranty protection. HCRA publishes the public licence registry, and Tarion checks enrollment against HCRA licensure when registering each home. Skipping enrollment is not a paperwork mistake; it is one of the items HCRA's enforcement arm investigates and prosecutes, with public charges and fines in the millions in recent years.
Freehold and condominium enrollments differ in mechanics, not principle. For freehold homes - detached, semi-detached, townhomes sold on freehold title - the developer enrolls each home individually, the buyer's deposits sit with the developer subject to Tarion's deposit-protection coverage, and the warranty starts on the date of possession. For condominium units the deposits are handled differently because the Condominium Act requires all deposits to be placed in trust, which means the buyer's funds sit with a trustee (typically the developer's real estate counsel) rather than the developer's operating account. Tarion still enrolls each unit and registers warranty start dates at occupancy and at condominium registration for the common elements.
Deposit protection limits depend on the home type and price. Freehold homes priced at or under $600,000 carry deposit protection up to $60,000; freehold homes above $600,000 are protected at 10 percent of purchase price up to a maximum of $100,000. Condominium deposits are protected in full under the Condominium Act because they must be held in trust, with Tarion providing a $20,000 backstop in the rare case a deposit was not properly placed in trust. Tarion has announced a transition effective January 1, 2027 (originally scheduled for April 1, 2026) under which freehold purchasers must notify Tarion of their purchase within 45 days of signing to qualify for the maximum coverage; purchasers who register late or not at all will qualify for coverage from a separate fund capped at $15 million annually, which is the kind of detail you want to handle in your APS sales process rather than discover at a closing.
The Delayed Closing Warranty (for freehold) and Delayed Occupancy Warranty (for condominium) are where developer process discipline pays off. If a closing or occupancy date is delayed without proper notice, the purchaser is entitled to $150 per day for direct living expenses up to a maximum of $7,500. A separate notice penalty of $1,500 (calculated as $150 × 10 days) applies if the builder fails to give the required 10 days' advance notice of a delay. Living-expense compensation does not require receipts; reimbursement for moving and storage costs does. The implication for developers is straightforward: build a delayed-closing notice workflow that triggers at the right milestone, document every notice in the buyer record, and treat the 10-day notice as a hard operational deadline - losing $1,500 per buyer because a notice template was never set up is the most preventable warranty cost in pre-construction.
For developers planning a 2026 or 2027 launch, three operational items matter most. Confirm both HCRA licences (builder and vendor) are current and renewed on time, since lapses block new enrollments. Build the buyer-side Tarion registration step into your APS workflow so freehold purchasers can comply with the new 45-day notification window without depending on the sales rep to remember it. And maintain a single buyer record that captures enrollment number, deposit trust details, and every notice issued - because warranty claims years after possession are won and lost on documentation that should have been created at the moment of the underlying event.
