Deficiency List
Learn how a deficiency list works in Canadian real estate, when it's used, and how it helps protect buyers during new home purchases or inspections.

What is a Deficiency List?
A deficiency list is a documented record of unfinished, incomplete, or substandard items identified during the inspection of a newly constructed or renovated property.
Why a Deficiency List Matters in Real Estate
In Canadian real estate, especially with new home builds or condo purchases, a deficiency list is typically created during the Pre-Delivery Inspection (PDI) or final walkthrough. It helps buyers and builders track outstanding issues that need to be resolved before or shortly after possession.
Common deficiencies include:
- Scratched flooring or countertops
- Incomplete caulking or paintwork
- Improperly installed fixtures or appliances
- Missing hardware, cracked tiles, or non-functional outlets
The builder is usually responsible for correcting listed deficiencies within a specified timeframe, often under the terms of a home warranty program like Tarion in Ontario. Buyers should document issues thoroughly with written notes and photos and follow up to ensure completion.
A complete deficiency list protects buyers from overlooking defects and supports warranty claims or legal recourse if problems are not addressed.
Example of a Deficiency List in Action
During the PDI of a new condo, the buyer notes five deficiencies including a broken cabinet hinge and scuffed walls. The list is submitted to the builder for correction before move-in.
Key Takeaways
- Documents unfinished or flawed construction items.
- Used during new builds and PDIs.
- Guides builder repairs under warranty.
