Before applying for a building permit, make sure all required planning and zoning approvals are complete.

Your project may need:

  • site plan approval
  • minor variance approval
  • an amendment to the zoning bylaw or official plan

Visit the business, planning and development page for information on approvals and requirements.

The Planning team must provide approval before you apply for a building permit.

Drawings must be prepared by an architect, engineer or BCIN-qualified designer.

All drawings must be to scale and dated.
