Typical situations that may require a building permit include replacement of exterior wall insulation where exterior cladding or structural elements are altered, and work that affects fire separations or ventilation. Apply for permits and view technical requirements on the City of Markham Building Permits and Inspections page.[1]

The city may issue orders to stop work, compliance orders, and proceed with Provincial Offences where necessary; specific monetary fines or schedules are not specified on the cited page.[2]
