Heritage Alteration Review - Markham Property Owners
Markham, Ontario property owners with designated heritage properties must follow the city and provincial rules for any exterior changes that affect cultural heritage value. This guide explains when a heritage alteration review or heritage permit is required, who enforces the rules, how to apply, and what to expect during inspections and appeals. It draws on official municipal and provincial sources and is current as of May 2026 unless the cited page states otherwise.[1][2]
When a heritage alteration review is required
Alterations, additions, demolition or any change affecting the external appearance of a property designated under the Ontario Heritage Act or located in a Heritage Conservation District typically require a heritage alteration review and a heritage permit from the City of Markham. If a property is individually designated or lies within a Part V district, submit plans to the city for review prior to construction or demolition.
- Check whether the property is designated under the Ontario Heritage Act and whether a Heritage Permit is listed as required.
- Provide drawings, material samples and conservation rationale as requested by Heritage staff.
- Do not begin construction, demolition or cladding changes until the review is complete and any permit is issued.
Penalties & Enforcement
The City enforces heritage controls for designated properties and may issue orders, stop-work notices, or charges for non-compliance. Specific monetary fines for heritage alteration breaches are not specified on the cited municipal heritage guidance pages; see the Ontario Heritage Act for provincial authority and penalties where provided.[1][2]
