Frequently Asked Questions
Is a permit needed for interior demolition?▾
Often yes, especially if it touches structure, visible elements or a heritage sector. Check with your borough before starting.
How do I know whether asbestos is present?▾
Through characterisation done before the work, on materials likely to contain it. For an older building it is a required step, not an optional precaution.
Who protects neighbouring buildings?▾
The contractor, and it belongs in the contract: protections, work method, dust and vibration control, and liability insurance in case of damage.
Where does the debris go?▾
To authorised facilities, sorted where required. Disposal must be included and detailed in the quote.
How do I verify a contractor is licensed?▾
Ask for the RBQ licence number and search the Régie du bâtiment du Québec public registry.
Demolition in Montréal: what to know
Demolition, even partial, is regulated. In a dense city like Montreal, it also affects immediate neighbours.
The permit
Demolishing a building or part of one requires borough authorisation, with a more demanding process in heritage sectors. Even a significant interior demolition can require a permit.
Asbestos and lead
In a building from before the 1990s, asbestos can be found in insulation, floor coverings, adhesives and coatings. Characterisation before work is the rule, and removal follows strict CNESST requirements. A contractor who offers to demolish without checking puts you and those around you at risk.
Neighbours
Dust, noise, vibration, protecting adjoining buildings and occupying the street: all of it is planned before the first swing.
Licence
The contractor must hold a Régie du bâtiment du Québec licence, liability insurance and a CNESST clearance.
