HUD has recently revised the Quick Reference Guide for Environmental Review Requirements for RAD Conversions. This version provides a more streamlined organization of information, incorporates frequently asked questions that have come up over the past few years, and introduces simplified environmental reviews for RAD conversions to PBRA that do not entail any work. This guide is applicable to both components of RAD (i.e., for public housing, Mod Rehab, Rent Supp & RAP, and soon 202 PRAC conversions).
