What Is the Weatherization Assistance Program?
The Weatherization Assistance Program (WAP) is the nation's largest residential energy efficiency program for low-income households. Established in 1976 and funded by the US Department of Energy, WAP is administered through state energy offices and local Community Action Agencies (CAAs). There are over 800 local WAP agencies across the country.
WAP services are provided at no cost to eligible households — no loans, no liens, no repayment. A certified energy auditor visits the home, identifies the most cost-effective improvements, and a certified crew performs the work. The average investment per home has increased significantly with IRA funding, now averaging over $7,400.
✓ How to Apply — Contact Your Local CAA
There is no national WAP application. Contact your local Community Action Agency (CAA) or state energy office. Search energy.gov/wap or call 211 (United Way helpline) to find your local agency. Wait lists are common — apply as early as possible.
2026 Income Eligibility Limits
WAP uses 200% of the Federal Poverty Level (FPL). Some states set thresholds as high as 200% of state median income. Check with your local agency for state-specific limits.
| Household Size | WAP (200% FPL) | LIHEAP (150% FPL) | Auto-Qualify (60% SMI) |
|---|
| 1 person | $30,120 | $22,590 | $9,036 |
| 2 people | $40,880 | $30,660 | $12,264 |

2026 federal poverty guidelines. Alaska and Hawaii have higher thresholds. Recipients of SNAP, SSI, TANF, or Medicaid often qualify automatically — ask your local agency.
FAQ — Weatherization Assistance Program
Can renters get WAP weatherization?
Yes — renters can receive WAP services with their landlord's written permission. The landlord must agree not to raise rent for at least 12 months after weatherization (in most states) and must contribute a portion of costs for larger multifamily buildings. WAP prioritizes elderly, disabled, and households with children under 6, regardless of whether they rent or own.
How long is the WAP waiting list?
Wait times vary significantly by state and local agency — from a few months to over a year in high-demand areas. Apply as early as possible. Some agencies have separate priority lists for elderly (60+), disabled, and families with young children. If you're on a wait list, you can still apply for HEAR rebates and utility programs in the meantime.
What is the difference between WAP and LIHEAP?
WAP (Weatherization Assistance Program) pays for physical improvements to your home — insulation, air sealing, heating repairs. LIHEAP (Low Income Home Energy Assistance Program) helps pay your energy bills — it's a utility bill subsidy, not a home improvement program. Both are federal programs, both are income-based, and you can receive both. WAP is administered through DOE; LIHEAP through HHS.
Can I get WAP and HEAR rebates on the same home?
Yes — WAP and HEAR are separate programs and can be combined. WAP typically addresses the building envelope (insulation, air sealing, heating systems). HEAR specifically covers heat pumps, heat pump water heaters, and electrical upgrades. A WAP-eligible household that also qualifies for HEAR (below 150% AMI) can receive free weatherization from WAP plus up to $8,000 for a heat pump from HEAR.
