Which rules apply

Ontario Building Code §9.22 (masonry chimneys), CSA B365 (solid-fuel installations), and WETT SITE-Basic scope cover most chase cover work. Insurers typically ask for the WETT report post-completion; municipalities ask for permit sign-off pre-cover.

WETT SITE-Comprehensive, CSIA CCP or CCS, and WSIB clearance are the three signals adjusters and buyers accept without pushback. HRAI membership adds credibility on venting work.
