This report summarizes public government records near the address. It is not a home inspection, an environmental site assessment, legal advice or a health diagnosis. "No adverse records" means none were found in the datasets searched, not that none exist. Radon and lead can only be confirmed by testing the home. See how the score works and every data source.
