New Construction Deficiency Checklist for Ottawa Homes (2026)

Why New Home Deficiency Inspections Matter in Ottawa

Buying a new home in Ottawa is exciting, but it's not uncommon for new builds to have deficiencies — imperfections, incomplete work, or items that don't meet the builder's specifications or the Ontario Building Code. In fact, the typical new Ottawa home has 50–150 deficiency items at the time of possession. Deficiencies range from minor cosmetic issues (paint touch-ups, drywall imperfections, scratched fixtures) to serious concerns (grading issues, HVAC problems, plumbing leaks, window installa...

Frequently Asked Questions

How many deficiencies are normal in a new Ottawa home?

A typical new Ottawa home has 50–150 deficiency items at possession. Most are minor cosmetic issues (paint, drywall, caulking), with 5–15 being functional or more significant items requiring attention.

Should I hire a professional inspector for my new home PDI?

Yes, strongly recommended. A professional new-home inspector ($400–$700) has specialized tools and building code knowledge that typically identifies $5,000–$15,000 worth of deficiencies that homeowners would miss.

What's the deadline for reporting deficiencies to Tarion?

You have two main submission windows in the first year: the 30-Day Form (within 30 days of possession) and the Year-End Form (between days 345–365). Don't miss these deadlines as late submissions may void coverage.

What if my builder refuses to fix deficiencies?

Submit a formal Tarion warranty claim. Tarion will mediate between you and the builder. If mediation fails, request a conciliation inspection ($200–$400). Tarion's decision is binding on the builder. For major issues, consult a construction lawyer.

Are grading issues common in new Ottawa homes?

Yes, very common. Ottawa's clay soils settle significantly in the first 1–3 years. Negative grading (water pooling toward the foundation) is a warranty item. Builders are typically required to address grading within the first two years.
