Frame check

See the header that fails before the inspector does

Lay out a wall with its doors and windows. WorkToCode frames it, checks the studs and every header against the tables for what the wall carries and your town's snow load, and turns the member red with the size that works.

Ask

Ask in plain words, get the article

"Max rise for stairs in a house?" comes back with 200 mm and Article 9.8.4.1, page 742. Every answer quotes the code; if the text doesn't cover it, WorkToCode says so instead of guessing.

Numbers you can stand behind

Every span, spacing and snow load comes straight from the 2024 Ontario Building Code Compendium (January 16, 2025 update), with the table and page beside it so you can show it to the inspector.

Questions

Is this the official Building Code?

No. WorkToCode is an independent tool from webfaCeMEdia and is not affiliated with or endorsed by the Government of Ontario. It works from the published 2024 Compendium. Your building official has the final say, and an engineer where the code calls for one.

What does it cover?

Part 9 of Division B (houses and small buildings) and the supplementary standards in the Compendium, with the Part 9 span and framing tables built in.

Can I use it on my phone?

Yes. Sign in on the iPhone or Android app, or at worktocode.ca in any browser, with the same account.

How do I cancel?

From Account, choose Manage billing. Your access runs to the end of the month you paid for.
