HUD Radon Testing Requirements 2025

What Housing Commissions and Property Managers MUST Know

HUD’s environmental compliance rules are evolving FAST , and if you’re managing or funding properties with HUD dollars, missing these updates could cost you time, money, and compliance headaches.

Here’s your in-depth guide to the latest HUD radon requirements, including what they mean for housing commissions, multifamily properties, and the new Section 18 disposition program.

What Are the Latest HUD Radon Testing Requirements?

As of 2025, any HUD-funded property is subject to enhanced environmental review protocols that now require radon testing during the renewal process.

Housing Commissions must renew environmental reviews every 5 years, which now include:

  • Environmental Review Checklist

  • Radon Mapping

  • Radon Testing (New Requirement) 

Who Can Perform HUD-Approved Radon Testing?

According to HUD and NRPP (National Radon Proficiency Program) regulations, radon testing must be performed by NRPP-certified professionals.

That’s where firms like ETC (Environmental Testing & Compliance) step in as a trusted leader. With years of experience helping property owners stay ahead of HUD compliance requirements, ETC has become a go-to partner for housing commissions and multifamily property managers across the country.

HUD Multifamily Radon Testing Protocols: What’s Required?

For multifamily properties (think four-story or larger buildings), here’s what you need to do:

  1. Test ALL ground-contact units.

     

  2. Test 10% of the remaining units.

     

  3. Include Quality Control Measures:

     

    • 10% duplicate tests

       

    • 5% blanks

       

    • 5% spiked samples

 For duplexes and condos? Only test the lowest livable area.

Section 18 Disposition: Big Changes for Single-Family Housing

HUD is actively phasing out single-family public housing through its Section 18 disposition program — a major shift that’s already impacting housing commissions and public housing authorities nationwide.

If you’re planning to sell, demolish, or transfer ownership of any single-family units under this program, HUD mandates that you conduct asbestos, lead, and radon testing in every single unit involved in the disposition. This isn’t optional — it’s a strict compliance requirement that must be met before any transaction or redevelopment can move forward.

This is where ETC (Environmental Testing & Compliance) steps in as a single-source solution. With the certifications, staff, and systems already in place, ETC can handle all three required tests quickly, professionally, and in full alignment with HUD’s latest protocols. No need to coordinate with multiple vendors or worry about missed deadlines — ETC streamlines the entire process.

Many housing commissions have already begun taking action. For example, the Highland Park Housing Commission has reached out to ETC to assist with environmental testing as they prepare properties for Section 18 disposition. These transitions are time-sensitive and compliance-critical — and ETC is trusted to deliver fast, reliable results that help public housing authorities stay on track and within regulation.

If your agency is planning to participate in Section 18, partnering with ETC early can save time, reduce risk, and provide the peace of mind that everything is being done right the first time.
