If you have just had a lead inspection — or you are trying to understand one — this page explains the essentials in plain English: what lead is, what your report covers, what the numbers mean, and how to keep your home and family safe.
Lead is a toxic metal once common in house paint, plumbing and soil. In homes built before 1978, lead-based paint is the most common source — and as it chips, peels, or is disturbed during renovation, it creates fine lead dust that is easily swallowed or inhaled.
There is no known safe level of lead exposure. It is especially harmful to young children and pregnant women, where it can affect brain development, learning and behavior. That is why finding and controlling lead hazards matters.
These are two related things, often done together:
The combined report is the official record. It documents the property, the readings and lab results, which findings are hazards, and the recommended actions — the document you keep, share, and act on.
Your readings are compared against action levels set by federal and state rules — for paint, dust, soil and water. A result at or above the action level is flagged as a hazard that needs attention.
Which rulebook applies depends on the job — the EPA standard and a HUD-grantee program can set different floors, for example. A certified assessor applies the correct thresholds for your situation and confirms every safety-critical value before signing. If a number in your report is marked a hazard, it means it met or crossed that action level — not that your home is unsafe to enter, but that the finding should be addressed.
Action levels are set by regulation and can change over time. Always rely on your certified assessor and the citations in your report rather than a remembered figure.
While any hazards are being addressed, a few everyday habits lower exposure:
These are general precautions, not a substitute for the specific recommendations in your report or the advice of a certified professional.
Homes built before 1978, when lead-based paint was banned for residential use in the U.S. The older the home, the more likely lead paint is present.
Intact, well-maintained paint is lower risk. The danger rises when paint deteriorates or is disturbed — chipping, peeling or sanding — which creates lead dust.
An inspection finds where lead paint is; a risk assessment finds the hazards and what to do about them. Many jobs call for both, combined in one report.
