Crumbling Foundations

 Many homeowners in parts of our state have discovered that their home foundations are crumbling due to a mineral called pyrrhotite in the concrete used to pour their homes' foundations. Rep. Larson has worked side-by-side with Rep. Joe Courtney (CT-02), Senator Richard Blumenthal (D-CT), Senator Chris Murphy (D-CT) and local, state, and federal stakeholders to find solutions for Connecticut homeowners affected by this terrible issue. Congressional efforts have been focused on two areas: federal studies and tax relief. 

Tax Relief 

Beginning in 2016, Reps. Larson and Courtney began consulting with the Internal Revenue Service (IRS) and Treasury Department staff to find relief for homeowners. As a result of these meetings, on November 22, 2017, the IRS issued Rev. Proc. 2017-60 to enact a "safe harbor" for the treatment of crumbling foundation-related repair costs as a "casualty loss" deduction from a taxpayer's taxable income under Section 165 of the Internal Revenue Code. 

After the 2017 Republican tax law limited the casualty loss deduction to potentially lock out homeowners, Rep. Larson secured Rev. Proc. 2018-14, giving homeowners an additional  IRS permission for homeowners to continue to utilize the deduction for an additional three years. Rep. Larson is working with Rep. Courtney to pass the Casualty Loss Deduction Restoration Act, their legislation to give permanent tax relief to impacted homeowners. Additionally, the Congressmen secured $2 million for the Capitol Region Council of Governments (CRCOG) Gap Foundation Funding to assist with expenses not covered by the state’s relief program.    

Federal Studies

Working with Senators Murphy and Blumenthal, and Rep. Courtney, Rep. Larson has been able to secure three federal funding for studies on pyrrhotite and crumbling foundations: 

  • A Government Accountability Office (GAO) study to examine the financial impact of pyrrhotite in concrete home foundations. This study was completed in 2020. 

  • A U.S. Geological Survey to develop a map showing pyrrhotite occurrences across the United States. This research allows us to better understand other areas that may experience crumbling foundations in the future. This study was completed in 2020.  

  • A National Institute of Standards and Technology (NIST) study to research the effects of the mineral pyrrhotite on concrete aggregate. Since 2020, UConn’s Concrete Foundations Research Team has received millions of dollars from NIST to investigate issues caused by pyrrhotite anddevelop a risk assessment framework for impacted foundations, allowing homeowners and stakeholders to understand the damage caused by crumbling foundations and to make decisions about building occupation and rehabilitation.
