Cal. Civ. Code § 5:17-4.2
Abatement classification
Operative Text
(a) An abatement shall be classified as an interior or exterior worksite. (b) Interior worksites shall be classified as Level 1, 2, 3 or 4, as described in N.J.A.C. 5:17-4.3(c), based on typical applications, time limit for the abatement, resident location, barrier system, warning signs, ventilation systems, furniture, clean up requirements and dust sampling. (c) Exterior worksites shall be classified as Level 1, 2 or 3, as described in N.J.A.C. 5:17-4.3(c), based on typical applications, time limit for the abatement, resident location, barrier systems, playground considerations, security, signs, weather, clean up and porches. (d) Contractors shall follow the procedures specified in N.J.A.C. 5:17-4.3(c).
Under N.J.A.C. § 5:17-4.2, lead abatement work in New Jersey must be formally classified before it begins. Interior worksites fall into one of four levels (Level 1 through 4), while exterior worksites fall into one of three levels (Level 1 through 3). Each classification is determined by a set of factors—such as the scope of work, time limits, resident location, barrier systems, and cleanup requirements—that together define how the abatement must be conducted.

Property owners and managers overseeing lead abatement work in New Jersey should be aware that N.J.A.C. § 5:17-4.2 requires every abatement project to be assigned a specific worksite classification before work begins. Compliant operators typically ensure that their licensed abatement contractors have correctly identified whether the worksite is interior or exterior and have assigned the appropriate level under N.J.A.C. 5:17-4.3(c). Maintaining documentation of the classification and the procedures followed is a standard practice for demonstrating compliance.

Tenants living in properties undergoing lead abatement in New Jersey have an interest in knowing that N.J.A.C. § 5:17-4.2 requires abatement work to be formally classified—interior or exterior—and assigned a specific level that governs safety measures like barriers, ventilation, warning signs, and cleanup. These classifications are designed to protect residents during the abatement process, and tenants can ask their landlord or contractor which classification applies to their building. Tenants who have concerns about whether proper procedures are being followed may contact the New Jersey Department of Community Affairs or a local tenant-rights organization for guidance on available options.
