The Renovate, Repair and Painting Rule will affect you when you go to paint, repair or remodel your pre-1978 home -- unless you do the work yourself.  The rule states that contractors working on such homes must:

Have their firm registered with EPA

Have EPA-Certified Renovators on staff 

Use mandated lead safe dust-containment and clean-up protocols

Document all compliance measures.

EPA will enforce the rule by shutting down home projects with non-compliant contractors indefinitely. Picture a stop work order on a demolished kitchen.
