- major defect: A condition of a system or component that renders it non-working, non-performing, non-functioning or unsafe, and requires a professional contractor to further evaluate and repair, correct or replace.
- minor defect: A condition of a system or component that renders it non-working, non-performing, or non-functioning, and may be repaired, corrected or replaced by a professional contractor or the homeowner.
- cosmetic defect: A superficial flaw or blemish in the appearance of a system or component that does not interfere with its safety or functionality.
