Home Inspection Checklist Score Calculator

Rate each home inspection category from 0 (Poor) to 10 (Excellent). The calculator computes a weighted overall score and provides a condition rating for the property.

Foundation & Structure (0–10)

Roof & Attic (0–10)

Electrical System (0–10)

Plumbing System (0–10)

HVAC System (0–10)

Exterior & Drainage (0–10)

Interior Walls, Floors & Ceilings (0–10)

Windows & Doors (0–10)

Insulation & Ventilation (0–10)

Safety Features (Smoke/CO Detectors, Railings) (0–10)

#### Formula

Weighted Score (0–10):

WeightedScore = Σ (Scorei × Weighti)

Final Score (0–100):

FinalScore = WeightedScore × 10

Category Weights:

Condition Ratings: 85–100 = Excellent | 70–84 = Good | 55–69 = Fair | 40–54 = Poor | 0–39 = Critical
