Tarion coverage boundary — covers new homes, contract homes, RCCPs; does NOT cover renovations to existing homes or owner-built homes

Claim: What Tarion covers:

What Tarion does NOT cover:

  • Renovations to existing homes — full stop. Even substantial renovations are outside the ONHWPA.
  • Owner-built homes intended for personal occupation. The owner-built exemption has long been criticized by Cunningham and CPBH as a loophole.
  • Substantial renovations sold as "new" — case-by-case. Cohen LLP notes Tarion warranty cannot be bought for "houses re-built upon existing foundations (substantial renovation)" but Tarion has investigated cases where sellers misrepresented status. Whether the renovator meets the statutory definition of "builder" is fact-dependent (Miller Thomson analysis turns on degree of control).

Sources:

  • Cohen LLP commentary on substantial-renovation boundary.
  • Miller Thomson analysis of "builder" definition.
  • Tarion [email protected] (canonical edge-case channel).

Confidence: Verified.

For renovation client marketing: Be explicit that renovations are not Tarion-covered. Don't imply otherwise. Buyers comparing "new build vs. major reno" will appreciate the honesty — and your sales team won't have to walk back implied promises later.

Companion: RenoMark certification — CHBA private-sector renovation program; minimum 2-year written workmanship warranty, liability insurance, written contract, code of conduct covers the practical alternative — RenoMark + in-house workmanship warranty.
