Understanding the Tarion Builder Directory

Every builder selling new homes in Ontario must be licensed. Before you sign anything, you can look them up in a publicly available registry — and knowing how to read it gives you a meaningful edge.

What the Ontario Builder Directory is

The Ontario Builder Directory is a public registry maintained by Tarion — the organization that administers new home warranty protection in Ontario under the Ontario New Home Warranties Plan Act. Any builder who wants to sell new homes or condominiums in Ontario must be enrolled with Tarion and appear in this directory.

The directory is publicly searchable at no cost. You do not need an account. It covers freehold homes, condominiums, and townhouses — anything built and sold as a new residential property.

How to search it

Go to hbb.tarion.com and search by builder name, company name, or registration number. You can also search by city or postal code if you want to see who is active in a specific area.

Tip: builders sometimes operate under multiple corporate entities. Search both the brand name you see on the sales office and the legal company name, which may differ. Your Agreement of Purchase and Sale will include the vendor's legal name — cross-reference that directly.

What the results show

Each builder listing displays several data points. The most important ones to understand:

Licence status

A builder's licence can be in one of several states:

  • Active — currently licensed to build and sell new homes in Ontario. This is what you want to see.
  • Suspended — the licence has been suspended, often due to outstanding warranty claims, non-compliance, or financial issues. A suspended builder cannot enter new purchase agreements.
  • Revoked — the licence has been permanently cancelled. The builder cannot legally sell new homes.
  • Expired — the licence has lapsed and has not been renewed.

If you are signing a pre-construction agreement, the vendor must hold an active licence at the time of signing. Confirm this. A builder who was active two years ago may not be active today.

Condition-free status

The directory indicates whether a builder holds a condition-free licence. Conditions on a licence signal that Tarion has imposed specific requirements — typically because of past warranty failures, complaints, or regulatory concerns. A licence with conditions is not the same as a suspended licence, but it is worth noting and asking about.

Claims history

The directory shows the number of homes a builder has enrolled under warranty and the number of claims filed against those homes. From this, you can calculate a claims-per-home ratio — divide total claims by total homes enrolled.

No industry-standard benchmark defines a “good” ratio universally — every home has some warranty activity, and a large volume builder will naturally show higher absolute claim counts. What you're looking for is context: a builder with 500 homes enrolled and 12 claims tells a different story than one with 500 homes and 280 claims. Compare against other builders in a similar volume range, not just the raw number.

The directory also distinguishes between claims that resulted in conciliation (a formal Tarion dispute process) and those resolved earlier. A high conciliation rate can indicate a builder who does not resolve warranty issues without being compelled to.

Possession and warranty history

For active projects or completed ones, you can see possession dates and whether the builder has a history of delayed closings that triggered warranty events. Repeated delays that pushed possession past Tarion's permitted period result in automatic compensation obligations — this shows up in the record.

What the directory does not tell you

The Ontario Builder Directory is a useful first check — not a complete picture. It does not show:

  • General construction quality, finishing standards, or customer service reputation
  • Litigation history beyond Tarion-administered claims (court actions, civil disputes, deposit forfeitures)
  • Financial health of the builder or whether project financing is in place
  • Complaints filed through the Home Construction Regulatory Authority (HCRA), which regulates builder licensing conduct separately from Tarion warranty

For a fuller picture, also check the HCRA's Builder and Vendor Directory at hcraontario.ca. The HCRA took over builder licensing from Tarion in 2021 and maintains its own disciplinary records. A builder can appear clean in the Tarion directory while having an HCRA conduct history worth knowing.

When to do this check

Do it beforethe sales appointment — not after you've already fallen in love with a floor plan. The information is free and takes five minutes. What you find won't necessarily stop you from proceeding, but it should inform the questions you ask and the amendments your lawyer negotiates.

Builders with strong track records and clean directories have nothing to hide — and most will welcome the informed buyer. If a builder is resistant to questions about their Tarion record, that tells you something too.
