An inspection is a surface-by-surface investigation to determine whether there is lead-based paint in a home or child-occupied facility, and where it is located. Inspections can be legally performed only by certified inspectors or risk assessors. Lead-based paint inspections determine the presence of lead-based paint. It is particularly helpful in determining whether lead-based paint is present prior to purchasing, renting, or renovating a home, and identifying potential sources of lead exposure at any time.
