How do I get a retroactive permit for work already done?

If you've had work done in Ottawa without permits, you can apply for a retroactive permit through the City of Ottawa, but expect additional scrutiny, inspections, and potentially costly corrections.

The City of Ottawa does allow retroactive permits for work completed without proper authorization, but the process is more complex than getting permits before starting work. You'll need to contact Building Code Services at 613-580-2424 or visit ottawa.ca/building to start the application process.

How the Retroactive Permit Process Works in Ottawa

First, you'll need to submit detailed drawings and specifications of the completed work, just as if you were applying for an original permit. The city requires these plans to demonstrate that the work meets current Ontario Building Code standards, not the standards from when the work was actually done. This means if your work was completed years ago, it may need to be brought up to today's code requirements.

The city will then schedule inspections to verify that the completed work matches the submitted plans and meets code requirements. Since inspectors can't see inside walls or verify the construction sequence, they may require you to expose certain areas of the work. This could mean removing drywall to inspect framing, electrical, or plumbing work - adding significant cost to your project.

What to Expect During the Process

Ottawa building inspectors will be particularly thorough with retroactive permits. They're looking for any code violations or safety issues that may have been missed during construction. Common problems include inadequate structural support, improper electrical connections, insufficient insulation, or ventilation issues. If violations are found, you'll need to correct them before the permit can be approved.

The fees for retroactive permits in Ottawa are typically double the standard permit fees, so expect to pay $200-600 for simple projects, or $1000-4000+ for major renovations or additions. Processing times are also longer - usually 4-8 weeks compared to the standard 2-4 weeks for regular permits.

When Retroactive Permits Are Most Critical

You absolutely need retroactive permits for structural changes, electrical work, plumbing modifications, or additions to your home. The City of Ottawa takes these seriously because they affect safety and property values. If you're planning to sell your home, most real estate lawyers will require proof that major work was properly permitted.

For electrical work specifically, you'll also need ESA (Electrical Safety Authority) approval. Even with a retroactive building permit, ESA may require additional inspections and corrections. Check esasafe.com or call 1-877-372-7233 to understand their retroactive inspection process.

Potential Complications and Costs

Be prepared for the possibility that some work may need to be redone or modified to meet current codes. This is especially common with older electrical work, structural modifications, or ventilation systems. The cost of corrections often exceeds the original permit fees by thousands of dollars.

If you're working with insurance claims or planning to sell, get the retroactive permit process started immediately. Some insurance companies may deny claims for unpermitted work, and buyers often negotiate significant price reductions for homes with unpermitted renovations.
