What do building inspectors look for during a renovation inspection?

Building inspectors in Ottawa focus on code compliance, safety, and ensuring work matches your approved permit drawings during renovation inspections.

When a City of Ottawa building inspector arrives at your property, they're primarily verifying that the renovation work complies with the Ontario Building Code and matches what was submitted in your permit application. The inspection isn't about aesthetics or quality of finishes - it's about safety, structural integrity, and code compliance.

What Inspectors Examine

Structural elements receive close attention during renovation inspections. If you've removed or modified walls, the inspector will verify that proper support has been maintained and that any new beams or posts are correctly sized and installed. They'll check that foundation work meets code requirements and that any structural modifications follow the approved drawings.

Electrical systems must comply with the Ontario Electrical Safety Code. The inspector will verify that new circuits are properly installed, outlets are correctly placed (especially in bathrooms and kitchens), and that GFCI protection is installed where required. Remember, electrical work also requires a separate ESA inspection - the building inspector may ask to see your ESA certificate.

Plumbing installations are checked for proper venting, drainage slopes, and fixture placement. In bathroom renovations, they'll verify that new plumbing meets current code requirements, including proper spacing around toilets and accessibility considerations if applicable.

Insulation and vapor barriers are crucial inspection points, especially in Ottawa's climate. The inspector will check that insulation values meet current code requirements and that vapor barriers are properly installed and sealed.

Fire safety measures including smoke detector placement, egress window requirements (particularly important in basement renovations), and fire separation between units in multi-unit buildings receive careful scrutiny.

Common Issues That Cause Failed Inspections

Many Ottawa renovations fail inspection due to work not matching the permit drawings. If you've made changes during construction, you need to submit revised drawings before the inspection. Missing permits for related work also cause problems - if your renovation required electrical or plumbing changes, those permits must be in place.

Inadequate ventilation, particularly in bathrooms and kitchens, frequently causes issues. Ottawa's building code has specific requirements for exhaust fan capacity and ducting that must be met.

Preparing for Your Inspection

Schedule your inspection through the City of Ottawa at 613-580-2424 or online at ottawa.ca/building. Give at least 48 hours notice for scheduling. Ensure all work is complete and accessible - don't install drywall over framing that needs inspection.

Have your permit documents on-site along with any ESA or gas permits. If you've made changes from the original drawings, have documentation ready to explain the modifications.

Your contractor should be present for the inspection if they performed the work. They understand what was done and can answer technical questions about installation methods and materials used.

After the Inspection

If the inspection passes, you'll receive approval to proceed to the next phase or, for final inspections, your occupancy permit. If issues are identified, the inspector will provide a written list of deficiencies that must be corrected before re-inspection.

Re-inspection fees apply in Ottawa (typically $100-200), so it's worth ensuring everything is code-compliant before the first inspection. Work with contractors who understand Ottawa's inspection process and current OBC requirements to avoid delays and additional costs.

For complex renovations, consider having your contractor do a pre-inspection walk-through to identify any potential issues before the official inspection.
