Residential Condominium Conversion Projects (RCCPs) — Tarion covers post-2018 conversions but pre-existing elements (façade, foundation) excluded from year-1 workmanship

Claim: Tarion covers Residential Condominium Conversion Projects (RCCPs) — buildings converted to residential condominiums after January 1, 2018. One key exception: pre-existing elements (e.g., the original façade, foundation, structural elements retained from the prior building) are not covered by the year-1 workmanship and materials warranty. They are covered for OBC violations, water penetration, distribution systems (year 2), and major structural defects (years 3-7).

Source: Tarion Registrar Bulletin 51 (Residential Condominium Conversion Projects).

Confidence: Verified.

Why this matters: RCCPs are a fast-growing segment in Ontario urban infill. Buyers of a converted-warehouse condo often don't realize the brick façade they bought into has a different warranty regime than the new mechanical systems. Builder marketing copy should mention this distinction honestly — it's a regulatory fact, not a marketing weakness.

Related coverage: Tarion 1-2-7 warranty in full — year-by-year coverage from possession through year 7 (workmanship, building envelope, distribution systems, MSD), Condo common-elements warranty — condo corporation files claims; performance audit in year 1 by board-retained engineer can itself be the warranty form.
