About HomeFree

The materials we touch, interact with, and are surrounded by every day affect us in ways most don't understand. HomeFree works to shine a light on toxic chemical exposures and transform the built environment by empowering decision makers to identify and use safer building products. As a national program co-created with affordable housing practitioners and designers, we work to improve the health of all people and the planet, especially marginalized communities and children who are disproportionately impacted by toxic chemicals.


HBN’s in-depth research into the hazards associated with toxic chemicals in building materials shapes our guidance on healthier product solutions.


HomeFree’s evidence-based tools and resources make it easy to implement healthier materials into your project that meet cost and performance requirements.


We partner with affordable housing collaboratives, green building certifications, and state housing and environmental agencies to scale the use of healthier materials and transform the market to safer products.
