Tarion backstops the warranty. HCRA licenses the builder. Two regulators, two bulletin systems, and a compliance program that only checks one of them is only half watching.
Key takeaways
A builder juggles two regulators with two separate bulletin systems: Tarion, which backstops the statutory warranty, and the Home Construction Regulatory Authority (HCRA), which licenses the builder or vendor doing the work. A builder of new homes must be licensed as a builder, and a builder who both builds and sells must be licensed as a builder/vendor. Knowing which one just changed, and when, is not optional reading — both instruments carry operational weight.
The split is not accidental — it is the result of a restructuring. Tarion revised its former Builder Bulletin framework, with the launch of HCRA: some prior bulletins were discontinued, others realigned, effective February 1, 2021. Since then, Tarion’s current bulletins have included RB01, the Customer Service Standard, effective May 1, 2024, RB04, How Chargeability is Determined and Applied, also effective May 1, 2024, and RB15, Enrolment Fees, effective September 1, 2025.
Tarion describes its Registrar Bulletins as “operational policy statements”, some prescriptive and some informational, “enforced through vendor builder agreements”. That matters practically: a bulletin is not advisory reading a builder can skim and set aside — it is incorporated into the contract that keeps the enrolment active.
HCRA splits its own guidance into two tiers with different weight. A Directive is “a specific requirement relevant to how licensees operate as builders and/or vendors”, while an Advisory provides “general information about licensing that is important for licensees to know” and does not itself apply to specific requirements. As of this writing, HCRA lists four directives — Addenda to Agreements of Purchase and Sale, the Condominium Information Sheet, Floor Area Calculations, and Licence Display Requirements — alongside 15 numbered advisories, ranging from a general Guide to Good Conduct through to legal requirements for sellers of new homes.
The two directives most likely to touch a sales file directly — Addenda and the Condominium Information Sheet — are drafted with operational language: HCRA states these documents should be included with the Agreement of Purchase and Sale. A builder that has not checked whether its purchase-and-sale template still matches the current addenda language is carrying compliance risk in its contracts, not just in its site practices.
Both regulators offer a way to be told rather than having to go looking: Tarion runs the BuilderLink portal and a newsletter subscription, and HCRA offers an e-news sign-up alongside its own Builder Portal where directives and advisories are indexed. Subscribing to both, and assigning one named person to log every new item against its effective date, converts an occasional website check into a habit that survives someone being on vacation the week a bulletin lands.
The effective date matters as much as the content. RB15’s enrolment fee change, for example, took effect September 1, 2025 — a date-triggered change that needs to reach whoever handles Tarion enrolments and accounting, not just the people running PDIs or warranty-year communication on site. A tracking log that records effective dates against which department needs to act catches that kind of split ownership before an old fee schedule gets used past its date.
HCRA licensing itself has four categories that a bulletin-tracking program needs to know which of them applies before deciding whose desk a new directive lands on: a builder of new homes must be licensed as a builder, a seller of new homes must be licensed as a vendor (seller), a builder who both builds and sells must be licensed as a builder/vendor (seller), and a builder of contract or custom homes on land the owner already holds must be licensed as a vendor (seller) and builder. A company that builds and sells is subject to bulletins touching both roles at once, which is exactly why a single named owner — not “sales” and “construction” each assuming the other is watching — matters more here than it might elsewhere.
Neither regulator treats a missed bulletin as a paperwork slip. On the HCRA side, “an administrative penalty” is described as “a financial penalty, similar to a fine, that can be issued for a range of violations” under the New Home Construction Licensing Act, 2017 and the Ontario New Home Warranties Plan Act, applying to licensed builders who fail to meet a standard and to unlicensed operators alike — the page does not publish a dollar maximum directly, pointing instead to O. Reg. 220/573 for the prescribed amounts. HCRA also maintains an Actions and Decisions archive where enforcement outcomes, including licence suspensions, are published. On the Tarion side, the exposure runs through the vendor builder agreement itself: since RB01 and its neighbours are enforced through that agreement, ignoring a bulletin is not a customer-service lapse in isolation, it is a term of the enrolment going unmet.
A new builder-vendor is enrolling its first project. Before any sales activity, it needs an HCRA licence in the correct category — builder, vendor, or builder/vendor, depending on whether the company builds, sells, or does both — and a Tarion enrolment, which under RB15 currently carries the fee structure effective September 1, 2025. On day one, the compliance lead subscribes to both the Tarion bulletin channel and the HCRA e-news sign-up, and cross-checks the current purchase-and-sale template against HCRA’s Directive 1 (Addenda) and Directive 2 (Condominium Information Sheet) before the first agreement goes out, rather than assuming last year’s template is still compliant. That same compliance role is a natural pairing with onboarding a new superintendent, since both are about a new hire inheriting obligations that started before their first day.
They come from two different regulators with two different roles. Tarion's Registrar Bulletins are operational policy statements enforced through the vendor builder agreement that backstops the statutory warranty. HCRA's Directives are licensing-side requirements tied to how a licensed builder or vendor is permitted to operate.
No. HCRA describes an Advisory as general information important for licensees to know, which does not itself apply to specific requirements of their work -- a lower tier than a Directive, which is framed as a specific operating requirement.
Yes. Tarion revised its former Builder Bulletin framework around HCRA's launch, discontinuing some bulletins and realigning others, effective February 1, 2021.
