Summary
Several federal programs provide grants and low-interest loans to help low-income homeowners repair, improve, and weatherize their homes in 2026. The USDA Section 504 program, HUD's HOME Investment Partnerships Program, and the Department of Energy's Weatherization Assistance Program are the primary federal vehicles, supplemented by state and local programs that can significantly increase total available funding.
USDA Section 504 Home Repair Program
The USDA Single Family Housing Repair Loans and Grants program, commonly known as Section 504, is one of the most accessible federal home improvement grant programs for rural homeowners. Administered by USDA Rural Development, it provides loans of up to $40,000 and grants of up to $10,000 to very low-income rural homeowners to repair, improve, or modernize their homes, or to remove health and safety hazards.
To qualify for the grant component (rather than the loan), applicants must be 62 years or older and unable to repay a loan. For the loan component, income must be below 50% of the area median income. The funds can be used for a wide range of repairs including roof replacement, foundation stabilization, electrical and plumbing upgrades, accessibility modifications for disabled residents, and the elimination of lead-based paint hazards. Applications are submitted to the local USDA Rural Development office. Funds are typically limited and allocated on a first-come, first-served basis, so applying early in the fiscal year (which begins October 1) is advisable.
HUD HOME Investment Partnerships Program
The HOME Investment Partnerships Program, funded by the U.S. Department of Housing and Urban Development, provides block grants to states and local governments to fund housing activities including owner-occupied rehabilitation. HUD allocates approximately $1.5 billion annually to participating jurisdictions, which then design their own local programs. This means the specific grant amounts, income limits, and eligible repair types vary significantly by location.
Homeowners do not apply directly to HUD. Instead, they apply through their local or state housing agency, Community Development Block Grant (CDBG) administrator, or a nonprofit housing organization designated as a Community Housing Development Organization (CHDO). To find your local HOME program administrator, visit HUD's website and search by state. Many jurisdictions prioritize repairs that address health and safety hazards, lead paint abatement, accessibility improvements, and energy efficiency. Income limits are generally set at 80% of area median income or below.
Weatherization Assistance Program (WAP)
The Department of Energy's Weatherization Assistance Program is the nation's largest residential energy efficiency program, serving approximately 35,000 homes annually with an average investment of around $6,500 per home. WAP funds flow from DOE to states, which then distribute them through a network of local community action agencies. Services provided include air sealing, insulation installation, heating and cooling system upgrades, water heater replacement, and installation of energy-efficient lighting and appliances.
To qualify, household income must be at or below 200% of the federal poverty level, or households must receive Supplemental Security Income (SSI) or Aid to Families with Dependent Children (AFDC). Renters can also receive weatherization services if the landlord agrees. There is typically a waitlist, as demand consistently exceeds available funding. Contact your state's weatherization program or your local community action agency to apply. The Low Income Home Energy Assistance Program (LIHEAP) often works in conjunction with WAP to address both weatherization and immediate heating and cooling crises.
Inflation Reduction Act Energy Efficiency Incentives
The Inflation Reduction Act (IRA) of 2022 created substantial new funding streams for home energy upgrades that remain active in 2026. Two key programs operate through the IRA:
- High-Efficiency Electric Home Rebate Act (HEEHRA): Provides rebates of up to $14,000 for qualifying electric appliances and home upgrades, including up to $8,000 for heat pump HVAC systems, $1,750 for heat pump water heaters, and $1,600 for insulation and air sealing. Income-eligible households (below 80% AMI) can receive 100% of costs covered; moderate-income households (80–150% AMI) receive 50% rebates. Programs are administered by states through the DOE.
- Energy Efficient Home Improvement Credit (25C): A federal tax credit of up to 30% on qualifying energy efficiency improvements, including insulation, windows, doors, heat pumps, and home energy audits. The annual cap is $3,200, with specific sub-limits for different improvement types. This is a tax credit, not a grant, but effectively reduces your cost.
State and Local Programs to Stack With Federal Funding
Federal programs are frequently supplemented by state housing finance agencies (HFAs), utility company rebate programs, and local government initiatives. Many states operate their own home repair grant and loan programs funded by a combination of federal Community Development Block Grant (CDBG) dollars and state appropriations. States like California, New York, Minnesota, and Washington have particularly robust programs that can add thousands of dollars in assistance on top of federal funds.
Utility companies are required in many states to offer energy efficiency rebate programs. These can cover significant portions of the cost of insulation, HVAC upgrades, smart thermostats, and LED lighting retrofits. Contact your electric and gas utility directly to ask about available rebates before beginning any energy improvement project. Stacking utility rebates with IRA tax credits and WAP services can sometimes result in homeowners paying little to nothing for major energy improvements. The Database of State Incentives for Renewables and Efficiency (DSIRE) at dsireusa.org is the most comprehensive resource for finding state and utility programs by location.
