Before you sign anything, run two lookups. Both are free, both are public records, and neither one requires the builder’s cooperation or even their knowledge.
One. Search the company by name in the Ontario Builder Directory, and read the enforcement history rather than only the status badge.
Two. Confirm that your specific home has been enrolled in the warranty program with Tarion, and confirm it before the construction contract is signed rather than after.
Most people run the first and believe they have run both. They answer different questions, and the second one is the one about your house. Here is what each actually tells you, and what has to be true before either matters.
First, work out whether any of this applies to your project
The whole licensing regime sits on one boundary, and getting your project on the correct side of it takes about a minute.
HCRA is direct on the rule: “In Ontario, all new home builders and sellers are required by law to be licensed by the Home Construction Regulatory Authority (HCRA). It is illegal to build or sell a new home without a valid licence.”
The word doing the work there is new. On one side of that line sit new homes, where a licence is mandatory. On the other sit renovations, and HCRA’s wording is worth reproducing with its own hedge intact: “Typically, renovations or upgrades to an existing home do not make the home ‘new’ and as such, do not require the builder to be licensed.”
Read that carefully if you are renovating, because it cuts both ways. Nobody is breaking a rule by renovating your kitchen without an HCRA licence. It also means a licence check tells you nothing useful about a renovator, and being told to “check they’re licensed” is advice built for a different project than yours. Your protection on a renovation comes from the contract, the insurance and WSIB coverage, and the permit and inspection process instead.
Three more placements worth knowing, all from the same HCRA page:
- Custom homes on your own land need two licences, not one. HCRA’s wording: “A builder who builds contract or custom homes on land owned by the owner of the home must be licensed as a vendor (seller) and builder.” If you own the lot and are hiring someone for a custom home build, you are confirming two things in the Directory, not one.
- Coach, laneway, and tiny homes generally require licensing and warranty coverage, which is worth knowing if a secondary suite is where you are heading. The licensing question follows the building, not the size, and our ADU work runs into this boundary regularly.
- Year-round liveability is part of the test. HCRA notes that if a new home includes heating, insulation, electricity (on or off-grid), potable water, plumbing, or waste disposal, and provides sleeping and cooking areas, a licence is required before construction can begin.
And if you are considering building it yourself: HCRA states that a person building a home for their own use on land they own may not require a builder’s licence, provided they do not sell the home after construction. The trade is significant and stated plainly on the same page. An owner-built home is not eligible for warranty coverage under the Ontario New Home Warranties Plan Act and will not have statutory warranty coverage. You also assume the builder’s role, which HCRA spells out as overseeing workplace safety and insurance, obtaining municipal permits, and directly contracting with subcontractors, trades, and suppliers.
Lookup one: what the Ontario Builder Directory actually shows
The Directory is a public, searchable registry hosted by HCRA, and it is more informative than most people realise because they stop at the licence status.
What it displays, in HCRA’s words: “a builder’s licensing status, years of activity, number of homes built, and any regulatory actions taken by the HCRA, including conduct concerns, charges, and convictions against the builder.”
That last clause is the part worth your time. A status badge is a yes or no. Conduct concerns, charges, and convictions are a record, and reading it takes another two minutes.
Two practical notes on how to search it well. You start by entering the builder’s name, but you can also refine results using filters like insolvency status or the name of a company director or officer. That second filter lets you look up the people behind a company rather than only the corporate name, which is a different question and sometimes a more informative one. And if you are buying a resale home built within the last seven years, you can use the same Directory to confirm the home’s warranty coverage.
HCRA also tells you what to do with a blank result, and it is worth quoting because it is less equivocal than most regulator guidance: “If a builder is not listed in the Builder Directory, it is likely they’re not operating legally.” And, plainly, “If a builder is not licensed, do not buy from them!”
One caution about this lookup that applies no matter how good the result looks. Licence status is live data. It reflects the day you search it, not the day you sign. Insolvency flags appear, enforcement actions get added, licences change status. If months pass between your research and your contract, run it again.
Lookup two: a licence is not your warranty
Here is where most homeowners stop one step short, and it is the single most useful thing in this post.
HCRA and Tarion are two organisations doing two jobs. HCRA “licenses and regulates the people and companies who build and sell new homes in Ontario”, and was designated by the Government of Ontario effective February 1, 2021 as the regulatory authority under the New Home Construction Licensing Act, 2017. Before that, Tarion had been the delegated authority responsible for licensing builders. Since the handover, in HCRA’s own words, “All matters related to homeowner warranty protection remain the responsibility of” Tarion.
So there are two registers, and they answer different questions. The Directory answers whether this company is legally permitted to build and sell new homes and what its record looks like. Tarion enrolment answers whether your specific home is covered. A builder can hold a valid licence and still not have enrolled your home.
The timing is the actionable part, and Tarion states it as a builder obligation: “Before entering into a construction contract with the owner of land, you must enrol the home in the warranty program. Failure to do so is a prosecutable offence.”
Turn that around and it becomes a homeowner’s tool. The enrolment is supposed to already exist at the moment you are being asked to sign. That makes it a reasonable thing to ask to see at the table, not a thing to chase afterwards. HCRA gives homeowners the same instruction from its side: if you plan to have a builder construct your home, confirm the builder is licensed by HCRA and that your new home is approved by Tarion and enrolled in the warranty plan before signing a contract.
There is a second document to expect at signing. Tarion notes that effective February 1, 2021, builders are required to attach the applicable version of the Warranty Information Sheet to every purchase agreement or construction contract at the time the document is signed, and that the sheet comes in six versions, one of which is for contract homes. If you are signing a construction contract and no Warranty Information Sheet is attached to it, that is a question to ask before you sign rather than a detail to let go.
As for what the warranty is: Tarion describes coverage that begins when you sign the Agreement of Purchase and Sale and remains in effect for up to 7 years even if the home is sold. It is “provided by the builder and backstopped by Tarion”, meaning the builder resolves warranty issues directly and Tarion assesses a claim if the builder does not. Coverage includes financial protection before you take possession, which covers deposit protection, delayed closing or occupancy, condominium cancellations, and financial loss coverage for contract homes, plus protection against construction defects afterwards. Tarion publishes the detail of which defects fall into which coverage period, and that is worth reading on their pages rather than a summary of them. The warranty also turns up again much later in a build, at closeout, which the custom home building process in Ontario covers in sequence.
What being unlicensed actually costs the homeowner
Enforcement is real and reasonably current, and the regulator’s framing of the consumer harm is more useful than a fine figure.
In a news release dated July 8, 2025, HCRA announced more than $170,000 in administrative penalties against two unlicensed builders and sellers, with violations that included selling a new home without a licence, failing to enrol a new home in the province’s warranty plan, and acting as a builder while unlicensed. The largest penalty, over $165,000, went to an individual for selling a new home without being licensed and without enrolling the home in the warranty plan. A separate penalty of $5,978 went to a company for acting as a builder while unlicensed.
Those are two specific enforcement actions from one release, not a fine schedule, and nothing here predicts any outcome in any other case.
The reason to care is the consumer side, which HCRA CEO and Registrar Wendy Moir put this way: illegal building and selling “misleads consumers and can leave them at higher risk for defects in their new homes and with limited warranty protection if something goes wrong.”
That is the real exposure, and it is worth being clear about the asymmetry. The penalty lands on the builder. The missing warranty lands on you, and a penalty issued against a builder does not retroactively create coverage on a home that was never enrolled. Which is the whole argument for spending ten minutes on two lookups before signing rather than seeking a remedy after. If something has already gone wrong, or a contract is already signed, that is a conversation for a real estate lawyer and for HCRA’s complaints process rather than for a blog post.
What these checks do not tell you
Both lookups establish permission and produce a record. Neither is a quality rating, and it would be a mistake to read them as one.
A licence confirms that a builder has met HCRA’s requirements and is legally permitted to build and sell new homes. It does not tell you whether they communicate well, run a realistic schedule, price honestly, or have built anything resembling your project. Nothing in a public registry answers whether this builder should build yours. That is what what to ask before hiring a builder is for, and the two posts are designed to be used together: this one is the record check you run without talking to anyone, that one is the conversation you have afterwards.
Voluntary industry membership is worth the same caution. It signals engagement with the sector. It is not a licence and does not substitute for one.
Timing matters too. The Directory search, the enrolment confirmation, and the construction contract all arrive at roughly the same moment as your financing, which is a busy week by design. Financing a custom home build in Ontario walks that part.
Run them on your whole shortlist
The useful move is not to check one builder. It is to run both lookups on every company you are seriously considering, on the same afternoon, before you have a favourite. Enforcement history reads very differently when you are comparing three records than when you are looking for a reason to proceed with one.
Then take what you find into the room. A builder who is happy to be looked up is telling you something, and so is one who is not. That applies to how we work and to every other builder you are talking to, which is exactly why the Directory is public. Go and look.
