The bill funds and coordinates voluntary standards, grants, guidance, certifications, and model codes to improve indoor air quality—especially for children and disadvantaged communities—but relies on authorized (not guaranteed) funding, voluntary adoption, and cost-sharing that shift upfront costs to building owners, taxpayers, and subnational governments and may produce uneven, delayed protections.
Students, children, and other building occupants (residents, patients, seniors) will face reduced exposure to indoor air pollutants because the bill funds assessments, guidance, grants, certifications, model codes, and minimum ventilation/filtration measures that support remediation and better indoor air quality.
State, local, and Tribal governments, schools, housing authorities, and nonprofits will receive authorized funding and technical assistance to assess and reduce indoor air pollution, enabling implementation of IAQ projects and local interventions.
Building owners, schools, and agencies gain standardized, science-based guidance, voluntary certifications, model code language, and measurement methods that make it easier to measure, manage, and communicate indoor air quality improvements.
Taxpayers could face new federal spending if Congress appropriates authorized amounts (e.g., up to roughly $100M/year plus additional authorizations), and because the bill authorizes but does not appropriate funds now, implementation is uncertain.
Homeowners, builders, landlords, renters, and manufacturers may face higher upfront construction, retrofit, equipment, and compliance costs (HVAC upgrades, filtration, certification) that could raise housing and operating costs and affect affordability.
Renters, low-income people, and occupants of uncertified or un-upgraded buildings may get uneven protections because many guidance, certification, and monitoring elements are voluntary or phased in over time.
Based on analysis of 11 sections of legislative text.
Authorizes EPA to develop indoor air contaminant lists and voluntary guidelines, run grants/technical assistance, create building certifications, fund NIST model code provisions, and assess school/childcare indoor air.
Official title: To authorize a national program to reduce the threat to human health posed by exposure to indoor air contaminants, and for other purposes.
Introduced September 3, 2025 by Paul Tonko · Last progress September 3, 2025
Creates a federal indoor air quality program to reduce health risks from indoor contaminants in schools, childcare, and other indoor spaces. It authorizes $100 million per year (FY2026–2030) for EPA to publish science-based indoor air guidelines, maintain a list of contaminants of concern, run technical and financial assistance and voluntary building certification(s), support model building-code provisions through NIST, fund an NAS study on an indoor air index, and perform periodic national assessments of school and childcare indoor air. The bill emphasizes voluntary guidelines, grants and technical help (with up to 75% federal funding), coordination with other federal agencies, protection for disadvantaged communities, and regular reviews of guidance and contaminant lists every five years; it does not preempt existing state or workplace safety laws.
