24 C.F.R. § 35.325
§ 35.325 Child with an elevated blood lead level. (24 CFR Part 35)
Operative Text
(a) If a child less than 6 years of age living in a federally assisted dwelling unit has an elevated blood lead level, the owner shall immediately conduct an environmental investigation. Interim controls of identified lead-based paint hazards shall be conducted in accordance with § 35.1330. (b) Other assisted dwelling units in the property. (1) If the environmental investigation conducted under paragraph (a) of this section identifies lead-based paint hazards, the owner shall conduct a risk assessment for other assisted dwelling units covered by this subpart in which a child under age 6 resides or is expected to reside on the date interim controls are complete, and for the common areas servicing those units. The risk assessments shall be conducted within 30 calendar days after receipt of the environmental investigation report on the index unit if there are 20 or fewer such units, or 60 calendar days for risk assessments if there are more than 20 such units. If the risk assessment identifies lead-based paint hazards, the owner shall control identified hazards in accordance with § 35.1325 or § 35.1330 in those units and common areas within 30 calendar days, or within 90 calendar days if more than 20 units have lead-based paint hazards such that the control work would disturb painted surfaces that total more than the de minimis threshold of § 35.1350(d). (2) The requirements for other assisted dwelling units covered by paragraph (b)(1) of this section do not apply if: (i) The owner both conducted a risk assessment of the other assisted dwelling units covered by paragraph (b)(1), and the common areas servicing those units, and conducted reduction of identified lead-based paint hazards in accordance with § 35.1325 or § 35.1330 between the date the child's blood was last sampled and the date the owner received the notification of the elevated blood lead level; or (ii) The owner provides the Federal agency documentation of compliance with evaluation, notification, lead disclosure, ongoing lead-based paint maintenance, and lead-based paint management requirements under this part throughout the 12 months preceding the date the owner received the environmental investigation report. (c) Interim controls are complete when clearance is achieved in accordance with § 35.1340. (d) The Federal agency shall establish a timetable for completing, and providing documentation to the agency on the environmental investigation, risk assessments, and lead-based paint hazard reduction when a child is identified as having an elevated blood lead level.
Under 24 CFR Part 35 § 35.325, when a child under age 6 living in a federally assisted unit is found to have an elevated blood lead level, the rule triggers a mandatory environmental investigation and interim hazard controls. If that investigation uncovers lead-based paint hazards, the owner must also assess other assisted units where young children live or are expected to live, along with shared common areas, within defined timeframes. Owners who recently completed compliant assessments and hazard reduction, or who can document a full year of ongoing lead-based paint compliance, may be exempt from the broader assessment requirement.
Plain English — not legal advice.
Under § 35.325, compliant operators promptly initiate an environmental investigation upon learning that a child under 6 in an assisted unit has an elevated blood lead level, and apply interim controls to any identified hazards. When hazards are found, operators extend risk assessments to other covered units housing young children and relevant common areas within the 30- or 60-day windows the regulation specifies, then remediate confirmed hazards within the applicable deadlines. Maintaining thorough documentation of ongoing lead-based paint evaluations, notifications, and maintenance throughout the preceding 12 months is a practice that supports eligibility for the exemption provisions in § 35.325(b)(2).
General guidance for property managers — not legal advice for your specific situation. Consult an attorney for advice on your case.
Section 35.325 gives residents of federally assisted housing the right to have lead-based paint hazards investigated and controlled when a child under 6 in the building is identified with an elevated blood lead level. Tenants can ask their property owner or the relevant federal agency about the status of any required environmental investigation or risk assessment, and can request documentation showing that required timelines are being met. Those who believe an owner is not complying may contact the applicable federal agency overseeing the assistance, or reach out to a local tenant-rights organization for guidance on available options.
