Implementation of the Reduced Elevated Blood Lead Level Triggering Response in Certain Assisted Target Housing

This summary provides an overview of HUD’s updated requirements for Multifamily owners of assisted target housing following the reduction of the Elevated Blood Lead Level (EBLL) threshold to 3.5 µg/dL. These changes impact compliance obligations, environmental response actions, and resident notification procedures for properties built prior to 1978.

Key Changes to EBLL Requirements

• HUD has reduced the EBLL threshold from 5 µg/dL to 3.5 µg/dL for children under age 6.
• Compliance with the reduced threshold was required by July 16, 2025.
• HUD will begin formal enforcement of the reduced EBLL threshold on June 1, 2026.
• These requirements apply whenever a health department or medical provider notifies HUD or the owner of a qualifying EBLL case.

Applicability to Multifamily Housing

The requirements apply to most HUD-assisted Multifamily properties classified as “target housing,” defined by Title X as housing built prior to 1978, except for elderly housing, housing for persons with disabilities, or zero-bedroom units—unless a child under age 6 resides or is expected to reside in the unit.

Required Actions for Multifamily Owners

• Initiate an environmental investigation of the affected unit and relevant common areas immediately upon notification of a qualifying EBLL case.
• Implement lead hazard reduction measures in compliance with the Lead Safe Housing Rule.
• Ensure residents receive required disclosures and educational materials regarding lead hazards.
• Document all actions taken and maintain records for HUD monitoring or audit.
• Coordinate with HUD staff, contractors, and public health authorities as required.

Multifamily Regulatory Requirements

• Multifamily properties receiving project-based assistance (PBRA, PBV, HOPWA, CoC, ESG) must follow the EBLL response procedures at 24 CFR 35.730.
• HUD-owned or mortgagee-in-possession (MIP) Multifamily properties must follow the EBLL procedures at 24 CFR 35.830, as required by 24 CFR 35.800.
• All actions must align with Subparts B–R of the Lead Safe Housing Rule (24 CFR Part 35).
