The County of Dufferin building division would like to thank all the Owners, Contractors and Designers who accepted and followed the Province’s emergency orders, exercised patience and worked diligently with us during these unprecedented times to ensure that the residents and visitors of The County of Dufferin are safe.
In support of the Provincial Government’s emergency order, Dufferin County's Building Division has implemented the following procedures:
Building inspections will continue for all construction deemed as essential by the Province of Ontario provided all persons onside are wearing non-medical masks and maintain a minimum of two (2) meter physical distancing for the duration of the inspection.
Construction without a permit is prohibited.
Dufferin County's Building Inspectors have the right to refuse an inspection if exposure to the COVID-19 virus is suspected or if individuals onsite are no practicing COVID-19 safety protocols.
In the event of suspected undue exposure to the County Building Inspector, a third party inspection report and photos from an engineer will be reviewed if submitted and may be accepted upon approval. A third party inspection may only be accepted for issued building permits that are deemed as essential construction by the Province of Ontario and the inspection has been refused by the County Building Inspector.
