How do I get previous unpermitted work inspected and approved?

In Ottawa, you can get unpermitted work inspected and approved by applying for a "retroactive permit" through the City of Ottawa Building Code Services, though the process involves additional steps and potential costs beyond a standard permit.

The City of Ottawa does allow homeowners to legitimize unpermitted work through their building permit system, but you'll need to work backwards to demonstrate compliance with the Ontario Building Code that was in effect when the work was completed.

Step-by-Step Process for Ottawa

Start by calling City of Ottawa Building Code Services at 613-580-2424 to discuss your specific situation. They'll guide you through the retroactive permit process, which typically involves:

You'll need to submit detailed drawings and specifications showing exactly what was done, often requiring you to hire a qualified professional (architect, engineer, or building designer) to create these drawings. The City needs to see that the work meets the building code standards that were in place when the work was completed - not current standards, which is important to understand.

For electrical work specifically, you'll need to involve the Electrical Safety Authority (ESA). Any unpermitted electrical work requires an ESA inspection regardless of when it was done. Contact ESA at 1-877-372-7233 or visit esasafe.com. They may require some work to be opened up for inspection, and any non-compliant work must be brought up to code.

For gas or HVAC work, the Technical Standards and Safety Authority (TSSA) must inspect and approve the work. Visit tssa.org or call their customer service line to arrange inspections.

What to Expect in Terms of Costs and Timeline

Retroactive permits in Ottawa typically cost 1.5 to 2 times the standard permit fee, so budget $300-1,000+ depending on the scope of work. The timeline is usually longer than standard permits - expect 4-8 weeks for review since the City needs to thoroughly evaluate work that's already completed.

You may face additional costs if the inspector finds code violations that need correction. Sometimes work needs to be partially dismantled for proper inspection, especially for structural, electrical, or plumbing elements that are now hidden behind finished walls.

Red Flags and Protection Tips

Be prepared that some unpermitted work simply cannot be approved if it violates setback requirements, exceeds allowable coverage, or creates illegal dwelling units in areas not zoned for them. The City cannot approve work that violates zoning bylaws, regardless of when it was completed.

Never ignore unpermitted work hoping it won't be discovered. It often surfaces during home sales, insurance claims, or if neighbors complain. Getting retroactive permits protects your investment and ensures you can sell your home without complications.

If you're buying a home with known unpermitted work, make the retroactive permitting process a condition of sale, or negotiate the estimated costs into your purchase price.

For electrical issues, use ESA's online portal at esasafe.com, and for gas/HVAC concerns, check tssa.org for certified contractors who can help bring work up to code.

The key is being proactive and working with the City rather than hoping unpermitted work stays hidden - Ottawa's building officials are generally helpful when homeowners take steps to legitimize their work properly.
