What are the inspection stages for a basement renovation?

In Ottawa, basement renovations typically require 3-5 inspection stages depending on the scope of work, with the City of Ottawa Building Code Services (613-580-2424) coordinating the schedule.

For a typical basement finishing project in Ottawa, you'll need to coordinate inspections through the City's building permit system. The standard inspection sequence includes:

Framing Inspection comes first, before any insulation or drywall goes up. The inspector checks that all framing meets Ontario Building Code requirements for ceiling heights (minimum 6'6" in most areas, 6'1" in some utility areas), proper lumber sizing, and structural connections. In Ottawa basements, they pay particular attention to beam supports and foundation wall attachments.

Electrical Rough-In Inspection happens after framing but before insulation. This requires a separate ESA (Electrical Safety Authority) inspection in addition to the City inspection. Your Licensed Electrical Contractor must pull the ESA permit and schedule this inspection through ESA at esasafe.com or 1-877-372-7233. The ESA inspection fee runs about $100-200 depending on the scope.

Plumbing Rough-In Inspection occurs if you're adding a bathroom or wet bar. This covers all supply and drain lines before they're covered up. If you're installing gas appliances like a fireplace or additional heating, you'll also need a TSSA inspection for gas lines.

Insulation and Vapor Barrier Inspection is critical in Ottawa's climate. The inspector verifies proper R-values (typically R-12 minimum for basement walls), vapor barrier installation, and air sealing. This is especially important in Ottawa where moisture control prevents mold issues common in our freeze-thaw cycles.

Final Inspection covers all completed work including drywall, flooring, fixtures, and final electrical connections. The City inspector checks egress windows if you're creating bedrooms (required by Ontario Building Code), smoke and carbon monoxide detectors, and overall code compliance.

What to Watch For: Some contractors try to rush inspections or skip stages. Never let them cover work before inspections are complete and passed. Failed inspections in Ottawa typically add 1-2 weeks to your timeline and additional fees. The City requires 48-72 hours notice for most inspections, so plan accordingly.

Secondary Suite Considerations: If you're creating a legal secondary dwelling unit, expect additional inspections for fire separation, sound transmission, and separate entrance requirements. This process can take 6-12 weeks through Ottawa's planning department.

Contact the City of Ottawa Building Code Services at 613-580-2424 or visit ottawa.ca/building to schedule inspections. Keep your permit number handy - you'll need it for every call. Most basement renovation permits in Ottawa run $200-800 depending on complexity, with inspection fees included.

For complex renovations involving structural changes, you may need additional engineering inspections beyond the standard sequence.
