Tarion RB-19 Reporting
Independent design review and field review for Ontario condominiums — from a partner in updating the RB-19 guidelines.
Tarion Registrar Bulletin 19 (RB-19) governs design review and field review for higher-risk condominium projects in Ontario. Introduced in 2021 to replace Builder Bulletin 19, it applies to Type C and Type D condominium projects whose construction began on or after February 1, 2021.
We've performed RB-19-style reviews since 2020 — before the formal rollout — and CEL is a partner with Tarion in the ongoing update of the RB-19 guidelines. Our reports clearly identify deficiencies, responsibilities and corrective actions so projects stay on schedule for security release.
