As mentioned earlier in this guide, landlords must provide prospective tenants with a lead paint disclosure. According to the Maine Department of Environmental Protection:
Every year, hundreds of children in Maine are poisoned by lead. Children less than six years old are most at risk of lead poisoning. Most lead poisonings in Maine are caused by exposure to dust from old lead paint. Lead can cause learning disabilities and behavioral problems that last a lifetime. More than half of Maine homes may have lead paint. Exposure to lead is most common in buildings built before 1950 (when paint contained up to 50% lead), and in buildings built before 1978 when repainting or remodeling is done.[i]
If you have young children living with you and are concerned about the presence of lead, contact the Maine CDC at 286 Water Street, State House Station 11, Augusta, ME 04333-0011, (207) 287-8016.
There may be financial resources available to abate lead in rental housing where young children are living. Lead abatement must be performed by licensed professionals.
