Part 50 vs Part 58 Environmental Reviews

HUD Part 50 Environmental Reviews

HUD Part 50 Environmental Reviews are required when HUD itself serves as the Responsible Federal Official (RFO). These reviews are typical for FHA-insured and HUD-administered programs, particularly multifamily and healthcare housing.

Common Part 50 Programs Include:

    • Section 221(d)(4) – New Construction & Substantial Rehabilitation

    • Section 220 – Urban Renewal / Redevelopment

    • Section 223(f) – Acquisition / Refinance

    • Section 223(a)(7) – Refinance of Existing FHA Loans

    • Section 231 – Elderly Housing

    • Section 232 – Healthcare Facilities (Assisted Living, Nursing Homes)

    • Section 241(a) – Supplemental Loans for Repairs & Additions

AZ-RI Consultants supports lenders, developers, and project teams by coordinating required studies, preparing HUD-compliant documentation, and assisting through HUD environmental clearance.

HUD Part 58 Environmental Reviews

HUD Part 58 Environmental Reviews are completed by Responsible Entities (REs) — typically local governments, housing authorities, or nonprofit organizations — for most HUD Community Planning and Development (CPD)–funded projects.

Common Part 58 Programs Include:

  • Community Development Block Grant (CDBG)

  • HOME Investment Partnerships Program (HOME)

  • Emergency Solutions Grants (ESG)

  • Community Project Funding (CPF / Earmarks)

  • Housing Trust Fund (HTF)

  • Section 108 Loan Guarantee Program

  • SHOP (Self-Help Homeownership Opportunity Program)

  • Continuum of Care (CoC)–related activities (environmental compliance support)

Under Part 58, AZ-RI Consultants assists Responsible Entities by:

  • Determining the appropriate level of review (CEST, EA, etc.)

  • Preparing Environmental Review Records (ERRs)

  • Supporting public notices and comment periods

  • Assisting with HUD clearance and release of funds

HUD Environmental Review FAQs

Question:
What is the difference between HUD Part 50 and Part 58 Environmental Reviews?

Answer:
HUD Environmental Reviews are completed under either 24 CFR Part 50 or 24 CFR Part 58, depending on who serves as the Responsible Federal Official (RFO).

  • Part 50 reviews are conducted when HUD itself acts as the RFO, typically for FHA-insured and HUD-administered programs.

  • Part 58 reviews are completed by Responsible Entities (REs) such as local governments, housing authorities, or nonprofits for most HUD Community Planning and Development (CPD) programs.

Question:
Who is responsible for completing a HUD Part 58 Environmental Review?

Answer:
Under Part 58, the Responsible Entity (RE)—usually a local government, housing authority, or nonprofit—completes the Environmental Review Record (ERR). AZ-RI Consultants supports REs by preparing compliant ERRs, coordinating environmental studies, managing public notices, and assisting through HUD clearance.

Question:
What HUD programs require Part 50 Environmental Reviews?

Answer:
Part 50 Environmental Reviews are commonly required for FHA-insured and HUD-administered programs, including HUD Multifamily Mortgage Insurance programs, HUD-assisted multifamily housing developments, and MAP and LEAN healthcare and multifamily loans.

Question:
What HUD programs fall under Part 58 Environmental Reviews?

Answer:
Part 58 Environmental Reviews apply to most HUD CPD-funded programs, including CDBG, HOME, ESG, Housing Trust Fund (HTF), SHOP, Section 108 Loan Guarantees, CPF-funded projects, and Continuum of Care (CoC)-related activities.

Question:
What is an Environmental Review Record (ERR)?

Answer:
An Environmental Review Record (ERR) is the official project file documenting compliance with NEPA and HUD environmental regulations. The ERR includes project descriptions, compliance determinations, environmental studies, public notices, and HUD clearance documentation.

How long does a HUD Environmental Review take?

Answer:
Timeframes vary based on project complexity and level of review. Categorical Exclusions may be completed in weeks, while Environmental Assessments (EAs) or projects requiring additional studies may take longer. Early coordination can significantly reduce delays.

Question:
Can a HUD-funded project start construction before environmental clearance?

Answer:
No. HUD prohibits committing or expending funds and starting physical work before environmental clearance is issued. Violations can result in loss of funding or project delays.

Question:
Does AZ-RI Consultants work with nonprofits and housing authorities?

Answer:
Yes. AZ-RI Consultants regularly supports nonprofits, housing authorities, local governments, lenders, and developers with HUD Environmental Reviews across Maryland, DC, Delaware, Pennsylvania, Virginia, and West Virginia.
