OBC 2024 cited answers across both compendium volumes.

Ontario Building Code 2024 has been mandatory since April 1 2025. CodesWise indexes both volumes of the OBC 2024 compendium, the OBC Supplement, the Ontario Fire Code, and the National Codes for cross-references. Provincial overlays are loaded; citations point to the right OBC clause every time.

What it actually changes

The OBC 2024 compendium is published in two volumes that don't always travel together on a job site. Add the OFC, the Supplement, and the constant NBC cross-references, and the right answer takes ten minutes to find.

Where CodesWise earns its keep

Volume 1 vs Volume 2 lookup

Both volumes are indexed under the same short_code. CodesWise picks the right volume for the clause without you needing to know which is which.

OBC vs NBC differences

Ontario diverges from National in dozens of clauses, energy compliance, sprinkler triggers, exterior wall ratings, dwelling-unit fire-separations. CodesWise picks OBC chunks first for Ontario users automatically.

Plan-review and permit prep

Cited answers ready for paste into review notes. Page-level PDF page-locate when you need to verify the source.

Multi-discipline coordination

When the structural engineer asks for a fire-rating mid-meeting, type the question and read the OBC clause back to them.
