Heritage Alteration Permit

Heritage Alteration Permit

A Heritage Alteration Permit is required to change a heritage designated property. These changes could include the replacement, removal, alteration, damage or destruction of heritage attributes on the property. For Part IV designated properties, Heritage Alteration Permit approval is required if alterations are likely to affect the heritage attributes of the property. For Part V designated properties, classes of alterations requiring Heritage Alteration Permit approval are identified in the applicable Heritage Conservation District Plans.

If you are unsure if a Heritage Alteration Permit is required, please contact a Heritage Planner at the City of London.

A Heritage Alteration Permit must be approved prior to altering the property. Applications for a Heritage Alteration Permit may go through the Delegated Authority process if alterations have not started. Alterations that may require approval include, but not limited to, construction of additions, window or door replacement, and porch replacement.
