Regulation lens

Check

Coming Q4 2026

Permits and zoning, before you swing a hammer.

Check is the regulation layer of the Compozit platform. Quebec building codes, Montreal borough rules, and structural risk flags — all baked in. The agent tells you what's legal and what isn't, before you spend a dollar.

What Check will do

  • Quebec building code logic natively
  • Montreal borough-specific zoning and setback rules
  • Permit application checklists per project type
  • Heritage and rental property restrictions
  • Structural and electrical risk flags
  • Estimated permit timelines per borough
