Who should apply for a building permit?

    When can work start?

    No work can start until the building permit is issued; this is normally no longer than a one-week process for most applications, from the time a completed application is submitted. As an example, the building code stipulates a building permit must be issued or rejected within 10 days from the time a completed application is submitted for a house.

    What inspections are required?

    The mandatory inspections required for your project will be indicated on the permit at the bottom of the permit form. Examples of the required inspections for a new house are:

    • when excavation is completed, footing forms are in place and prior to pouring concrete footings
    • when foundation walls are completed, drainage tile and gravel cover installed, damproofing installed and drainage layer installed, and prior to backfilling
    • when structural framing and mechanical systems are completed
    • when roughed in plumbing pipes are installed
    • when insulation and vapour barrier is installed and prior to drywall
    • when home is ready to be occupied
    • when project is completed

    It is your responsibility to ensure that either you or your contractor contacts the building inspector to request an inspection at least 24 hours before work proceeds from one inspection stage to the next.
