Lead Inspections & TestingBaltimore, MD & Surrounding Areas

Lead paint was banned for use in homes in 1978, but much of Baltimore’s housing was built long before that. Whether you’re a landlord who needs a lead certificate for a rental or a homeowner with young children, we’ll help you find out where lead is and what to do about it.

Lead certificates for Maryland rentals

If you rent out a home built before 1978, Maryland law requires you to register it with the Maryland Department of the Environment (MDE) and have it inspected by an MDE-accredited lead paint inspector at every change in tenancy. Baltimore City and Baltimore County also ask for your lead certificate number when you apply for or renew a rental license.

Full Risk Reduction

Required at every change in occupancy for pre-1978 rentals. The home must be free of chipping or peeling paint inside and out and pass lead dust testing.

Lead-Free & Limited Lead-Free

If testing shows the property is free of lead paint, it can be certified lead-free, which exempts it from annual MDE registration fees and future risk reduction inspections.

Modified Risk Reduction

Required after a tenant reports chipping or peeling paint, or after a child living in the home has an elevated blood lead level.

You’ll get a clear list of what needs to be fixed, such as peeling paint or high dust levels. Once the work is done, the unit can be re-inspected for its certificate.

If your home was built before 1978 and you have young children, are pregnant or are planning renovations, testing is a smart way to find lead hazards before they become a health problem.
