Conducting a comprehensive healthy homes inspection requires a systematic approach to assess various environmental factors affecting occupants' health and well-being. Begin by familiarizing yourself with the Healthy Homes Principles established by the U.S. Department of Housing and Urban Development (HUD), which include keeping homes dry, clean, ventilated, pest-free, safe, contaminant-free, and maintained. Prioritize areas prone to moisture accumulation such as bathrooms, kitchens, and basements, as dampness fosters mold growth and attracts pests. Inspect for water leaks, condensation, and signs of mold or mildew, addressing any issues promptly.
