We have no children living in our house, so I assume that anybody can work on it:
"The Environmental Protection Agency's new guideline requires housing contractors to be certified in lead-safe practices if they want to work on houses more than 30 years old.
The official ruling applies to work or structures built before 1978 and has children, six years or younger, present. Before 1978, most homes used lead paint. The practice is fazed out but if there is any renovations that expose lead, it can poison young children."
