2025 Homebuyer Grant Program

State and Tribal Indoor Radon Grants is sponsored by ENVIRONMENTAL PROTECTION AGENCY. The EPA assists states and federally recognized Tribes to provide radon risk reduction through activities that will result in increased radon testing, mitigation, and radon resistant new construction through the authorizing statute: Title III of the Toxic Substances Control Act (TSCA), the Indoor Radon Abatement Act (IRAA), Section 306. States and Tribes are encouraged to implement projects focused on assisting state radon programs, expanding radon testing of existing homes, increasing mitigation of homes with high radon levels, and promoting radon-resistant new construction. Funding Priorities - Fiscal Year 2025: Recipients will focus on adopting, or seeking to adopt, radon building codes for single family homes, promoting radon awareness through the medical community, state cancer control plans, childcare providers and real estate transactions, providing training and technical support on voluntary consensus standards for radon testing and mitigation, identifying and spreading best practices for building homes radon resistant and adopting radon in building codes, providing radon awareness building and/or education activities that target homebuyers, informing local school systems about radon exposure risk in schools and providing sample school testing and mitigation plans, developing or implementing processes to ensure appropriate, certification or credentialing of radon testing and mitigation service providers, collecting available radon test result data to develop locality-specific classifications of radon risks and to support the CDC Environmental Public Health Tracking Network radon site. The EPA will encourage state and Tribal grant recipients to work collaboratively with additional government agencies, non-profit organizations and private sector partners participating in the National Radon Action Plan (NRAP).
