Plain English

Section 42 U.S.C. § 4851b establishes the foundational vocabulary for the federal lead-based paint regulatory framework, defining key terms used throughout the chapter. It draws distinctions between concepts like 'abatement' (permanent elimination of lead hazards) and 'interim controls' (temporary exposure reduction), and between 'inspection' (surface-by-surface presence testing) and 'risk assessment' (broader on-site investigation of hazard severity and location). The definitions also establish which housing falls under the law's reach, most notably 'target housing,' which generally covers residential properties built before 1978, with certain exceptions for elderly or disability housing and zero-bedroom units without young children.

For Property Managers

Property owners and managers operating under 42 U.S.C. § 4851b should be familiar with how the statute distinguishes between the types of work and housing it covers, since these definitions determine which obligations apply. Compliant operators typically ensure that any lead hazard work is performed by a 'certified contractor' as defined in this section—someone who has completed a federally or equivalently state-approved training program. Owners of pre-1978 residential properties, which generally qualify as 'target housing' under § 4851b, commonly maintain records distinguishing between abatement activities and interim controls, as each carries different compliance implications under the broader chapter.

For Tenants

Tenants living in housing built before 1978 may be protected by the lead-based paint framework that 42 U.S.C. § 4851b helps define, particularly if their home qualifies as 'target housing' under this section. Understanding these definitions—such as what constitutes a 'lead-based paint hazard,' 'deteriorated paint,' or an 'accessible surface'—can help tenants recognize conditions that may trigger landlord obligations under the broader chapter. Tenants who believe hazardous conditions exist may explore options such as contacting a local housing authority, raising a violation as a defense in relevant proceedings, or reaching out to a tenant-rights organization for general guidance on how these definitions apply to their housing type.
