Safety rules
Some jobs are not DIY. H0U53 is designed to say so.
H0U53 is an educational and organizational tool. It is not a substitute for licensed professionals, emergency services, local building departments, manufacturer instructions, inspections, or legal advice.
Below are the stop conditions every guide is built to respect.
Local codes, permits, utility rules, and licensing requirements vary by location. Always verify with your local authority having jurisdiction, utility, manufacturer, or qualified professional.
