What happens if I build without a permit?
As a property owner, it’s your responsibility to ensure that a building permit is obtained, even if you are hiring a builder or contractor. If you are unsure whether you need a permit, contact the Building Department to inquire. The Building By-law and the Ontario Building Code Act have penalties of up to $50,000 upon conviction for illegal construction. The costs to the property owner becomes much higher due to legal/engineering requirements.
When do I need an inspection?
Once a building permit has been issued, there will be several inspections required at various stages of construction.
You are required to notify your Inspector once your project reaches a point where you are ready for each required inspection. The inspection is conducted using your copy of the approved permit plans. The Inspector must be able to see the entire building component being inspected. Any components that are covered before they have passed an inspection will have to be uncovered so they can be inspected.
The schedule below lists the various inspections that may be required for your project. Please note, not all inspections below are necessarily required for your project. Depending on the building project, multiple inspections can be conducted during one site visit such as: framing, HVAC rough in, and plumbing rough in.
If you have any questions about the required inspections for your project, please contact the Building Department.
Required Building Inspections
- Footing inspections are required at completion of formwork, before pouring concrete.
