Home Safety Score

Average Home Safety Score for Texas: B (83/100) across 794 scored of 2649 tracked ZIP records.

Model 4.0.0 uses the canonical components water-compliance, pfas-mcl-screen, radon-zone, annual-aqi across 3 required domains. The sections below provide additional context and do not change that score. Missing required evidence suppresses the score, and a favorable result is not a property-level safety certification.
