Office of Housing Environmental Review Resources

Welcome to HUD’s Office of Housing environmental review resources page. This page contains links to the Office of Housing’s environmental review guidance and resources.

An environmental review is the process of reviewing a project and its potential environmental impacts to determine whether it meets federal, state, and local environmental standards. The environmental review process is required for all HUD-assisted and insured Office of Housing projects to ensure that the proposed project does not negatively impact the surrounding environment, and that the property site itself will not have an adverse environmental or health effect on residents.

HUD’s Office of Environment and Energy (OEE) manages the overall environmental review process for HUD. You will find an overview of HUD environmental requirements on the Environmental Review page.

View detailed instructions for applicants and third-party providers assisting HUD with Part 50 environmental reviews for Section 202 and Section 811.

Quick Start Reference: Using HEROS as a Section 202 or Section 811 Applicant - Application Review Stage

Submission of Environmental Reports for the Section 202 or Section 811 Program

Environmental reviews for Section 202 or 811 applications are performed in two stages:

  1. 1During the application review stage, HUD performs only a preliminary environmental screen to identify any major adverse environmental conditions. At this stage, applicants must submit certain environmental documents, but these documents may be submitted either through the HUD Environmental Review Online System (HEROS) or by preparing the Partner Worksheets.
  2. 2If HUD selects a project for funding, the second stage requires the applicant to enter all environmental documents into HEROS.

Additional information can be found in the 2019 Section 202 NOFA and the 2019 Section 811 NOFA.

Housing Environmental Guidance

MAP Guide

Multifamily Accelerated Processing (MAP) is designed to establish national standards for approved lenders to prepare, process and submit loan applications for Federal Housing Administration (FHA) multifamily mortgage insurance. This MAP Guide provides guidance for HUD staff, lenders, third party consultants, borrowers, and other industry partners. Topics include mortgage insurance program descriptions, borrower and lender eligibility requirements, application requirements, underwriting standards for all technical disciplines and construction loan administration requirements. The MAP Guide only applies to FHA multifamily mortgage insurance programs. Except to the extent lender monitoring or enforcement activities overlap, Section 232 and other programs administered by the Office of Healthcare Programs are not addressed by the MAP Guide. Chapter Nine of the Guide is dedicated to environmental review and requirements.

Date Published: January 2016

Healthcare Mortgage Insurance Program Handbook

This Handbook is intended as a comprehensive guide to the Section 232 Program, and supersedes prior handbook or other guidance specifically on the Section 232 Program, consistent with statutory and regulatory requirements. Handbook chapters may include appendices which list the most recently published transactional documents, but the Handbook also covers transactions for which earlier versions of the documents were used and are in force. There may also be instances where existing guidance (particularly related to Borrower audited financial statement matters), references “Multifamily Housing”, because the guidance was issued at a time when the Section 232 Program was a part of the Office of Multifamily Housing, and thus is still applicable to Section 232 Projects. If a particular Section 232 program matter is not addressed in this Handbook, and appears in other guidance, questions regarding applicability may be raised with the Office of Residential Care Facilities (ORCF). Chapter Seven of the Handbook is dedicated to environmental review.
