Building owners, contractors, renovators and builders must distribute a warning pamphlet to building occupants before performing renovations to structures built before 1978. The pamphlet is required under federal regulations aimed at protecting residents from lead paint dust and debris. It describes the health hazards of lead paint and measures that can be taken to prevent exposure to contamination. It’s available in both English and Spanish.

Any work that disturbs more than two square feet of paint triggers the notification requirement. Failure to comply could result in criminal and civil penalties, with fines of up to $25,000 per day. The law exempts certain emergency renovations and repairs and also does not apply to studio apartments and rooms rented in individual homes.

The Environmental Protection Agency estimates nearly 3 million professionals in the building trades are subject to the new law, including painters, carpenters, drywall workers, lathers, and electricians and more than 200,000 property managers.
