4. AHJ considerations
Building requirements vary by municipality. Tenet flags known regional variations when relevant — for example, Toronto-specific amendments or Ottawa snow load references.
- City of Toronto
- City of Ottawa
- Regional variations flagged in answers when applicable
AHJ flags are informational only. You are responsible for confirming requirements with your local building department, fire department, and other authorities.
5. What is not covered
Tenet focuses on the Ontario Building Code compendium. The following are outside our indexed knowledge base:
- National Building Code (other provinces and territories)
- Full municipal by-laws and zoning ordinances
- Conservation authority requirements
- Fire department operational policies
- Permit office submission checklists
- Utility connection requirements
- Federal regulations outside OBC scope
6. How citations work
Every answer links back to the exact OBC clause or supplementary standard section. Inline references appear in the response text, and a sources panel shows the full citation with a link to the source document when available.
Example reference format: OBC 9.8.8.3.(1)
