Risks when permits are not obtained

By not obtaining permits for work done on your home, you are leaving yourself vulnerable to potential future legal and financial issues when selling your property or making an insurance claim. There could also be consequences if you do not correct the situation, such as:

• Enforcement action issued by a Safety Codes Officer.
• A fine for building without a permit.
• Having to undo work that has been completed.
• Future legal and financial issues when selling your property or making an insurance claim.
• Having to do more work than was originally planned and budgeted, to fix deficiencies.
• Potential liability to you, the homeowner, in the event of an accident.

As a homeowner, you are responsible for paying any penalties, even if you hired a contractor who assured you that permits were not required.
