Programs that work the same in every state

These programs exist nationwide. Rather than repeat them in all 51 jurisdictions, they are described once here; each state’s page lists the local contacts (state offices, administering agencies, phone numbers) and notes how the program is delivered there.

USDA Section 504 Home Repair Loans and Grants

USDA Rural Development offers very-low-income rural homeowners repair loans up to $40,000 at a 1% fixed rate for 20 years, plus grants up to $10,000 for owners aged 62 and older to remove health and safety hazards. Loans and grants can be combined up to $50,000 ($55,000 in presidentially declared disaster areas). It applies in every state, but eligibility is limited to designated rural areas, and applications go through the state Rural Development office.

LIHEAP (Low Income Home Energy Assistance Program)

The federally funded Low Income Home Energy Assistance Program helps low-income households with heating and cooling bills, crisis assistance, and in many states weatherization. Each state sets its own income threshold (often a percentage of the state median income or federal poverty level) and administers the program, usually through local Community Action Agencies. The federal clearinghouse with state-by-state profiles is a good seed for each state: https://liheapch.acf.gov/.

Weatherization Assistance Program (WAP)

The U.S. Department of Energy’s Weatherization Assistance Program funds free energy-efficiency improvements (insulation, air sealing, heating-system work) for income-eligible households, typically at or below 200% of the federal poverty level, with priority for older adults, people with disabilities, and families with children. Each state designates an administrator (often the state housing or community services agency) that funds local subgrantee agencies.

VA housing grants for disabled veterans (SAH / SHA)

The Department of Veterans Affairs offers Specially Adapted Housing (SAH) and Special Housing Adaptation (SHA) grants to veterans and service members with qualifying service-connected disabilities, to buy, build, or modify a home for accessibility. These are federal and available in every state. Details: https://www.va.gov/housing-assistance/disability-housing-grants/.

How the national and state layers fit together

For each state, the dataset records the in-state delivery details for these federal programs (for example, the state LIHEAP and WAP administrators and how residents apply) rather than restating the federal rules. When a program is purely federal with no state-specific variation, the state summary points here.
