Cal. Civ. Code § 5:17-3.5
Lead hazards
Operative Text
(a) The following lead dust levels resulting from a lead screening shall indicate that a full evaluation shall be recommended in the report produced by the inspector/risk assessor: 1. Floor wipes in excess of 10 [mu]g/square foot; or 2. Window sill wipes in excess of 100 [mu]g/square foot. (b) The following lead dust levels shall indicate lead hazards: 1. Floors--equal to or greater than 10 [mu]g/square foot; 2. Interior window sills--equal to or greater than 100 [mu]g/square foot; 3. Window wells -- equal to or greater than 400 [mu]g/square foot.
Under N.J.A.C. § 5:17-3.5, specific lead dust concentration thresholds—measured in micrograms per square foot—determine when a property is considered to have a lead hazard and when a full evaluation must be recommended. Floor wipe samples at or above 10 µg/sq ft, interior window sill samples at or above 100 µg/sq ft, and window well samples at or above 400 µg/sq ft each constitute a lead hazard. Screening results that meet or approach these thresholds trigger formal reporting requirements by the inspector or risk assessor conducting the evaluation.

Property owners and managers subject to N.J.A.C. § 5:17-3.5 generally work with licensed inspectors or risk assessors who are required to document lead dust levels against the thresholds set in this provision. When screening results exceed the floor, window sill, or window well benchmarks, the inspector's report must recommend a full evaluation, and operators typically ensure that any identified lead hazards are addressed through remediation or abatement. Maintaining records of all lead screenings, reports, and any subsequent remediation work is a standard practice for demonstrating compliance with this section.

Under N.J.A.C. § 5:17-3.5, tenants have an interest in knowing whether lead dust levels in their home have been tested and whether results met or exceeded the hazard thresholds for floors, window sills, or window wells. If a screening has been conducted, tenants can request a copy of the inspector's or risk assessor's report, which is required to note when a full evaluation is recommended. Tenants who have concerns about lead hazards or believe required evaluations have not been completed may contact the New Jersey Department of Community Affairs or a local tenant-rights organization for information about available remedies.
