Work on classified property, a protection area or heritage site: obtain authorization before construction

Check status and intervention, consult the regional office, document materials and effects, then await written conditions.

Priority

A municipal or archaeological permit does not replace heritage authorization. Unauthorized work may lead to a restoration order.

Confirm the scope

Check the register for the property, site, area, category, character-defining elements and competent authority.

Describe existing and proposed plans, materials, methods, excavation, signage, landscape and schedule with photos.

Consult the regional office and file the signed form with professional plans and related authorizations.

Await the decision, incorporate every condition, start within the allowed period and document the work.
