What happens if you own or purchase a home built prior to 1978 and you need new paint inside/ or outside? As a homeowner you do not have to have a license or certification to do the paint work. If the home is an investment house or if the paint work is commercially done, the painter must have a Lead Based Paint Certification prior to doing any of the paint work. The certification training is reqired by the Federal Government (HUD) and there are NO exemptions. You are responsible for determining that the painter has the certification.
