Revisiting Multifamily Radon Regulations, One Year Later

By Victoria Cardona and Jake Wegleitner

Fannie Mae and Freddie Mac’s higher sampling requirements can uncover more units with elevated radon levels, so multifamily owners should be prepared for radon mitigation.

By Victoria Cardona & Jake Wegleitner, published on GlobeSt.com on July 30, 2024

Just over a year ago, the Federal Housing Finance Authority (FHFA) implemented new standards for radon screening for Fannie Mae and Freddie Mac multifamily loans. Sampling requirements increased from 10% of ground floor units to 25% of ground floor units. Naturally, sampling more units leads to discovering more units with elevated radon levels, which translates to more need for radon mitigation. Buyers of multifamily properties, as well as their lenders, should know what to expect when faced with a radon mitigation project.

In this Globe St. article, Victoria Cardona and Jake Wegleitner, discuss the state of multifamily radon regulations one year later.
