Heritage Alteration Permits

Common triggers include demolition, significant exterior alteration, additions, or changes to defining heritage elements.

  • Prepare clear drawings and a Heritage Impact Statement if requested by staff.
  • Submit application, photos, and materials list to Heritage Planning staff.
  • Staff review and recommendation; some matters go to the Heritage Guelph Committee or council for decision.
  • If approved, conditions may be attached; proceed when you receive a written permit or letter of approval.
Always contact Heritage Planning before you finalize design to avoid costly rework.
