Weatherization Assistance Program: Eligibility, Priority, and Coverage

You qualify for the Weatherization Assistance Program if your household income is at or below 200% of the federal poverty guidelines, or if someone in your home has received Supplemental Security Income or Temporary Assistance for Needy Families cash payments within the past 12 months. For a family of four in the contiguous states, the 2026 income ceiling is $66,000. The program is federally funded through the U.S. Department of Energy and delivered by state and local agencies, and it covers renters as well as homeowners.

Income Limits by Household Size

The DOE ties eligibility to the poverty guidelines published each year by the Department of Health and Human Services, so the dollar figures shift annually.¹ For 2026, the 200% thresholds in the 48 contiguous states are:²

1 person: $31,920
2 people: $43,280
3 people: $54,640
4 people: $66,000
5 people: $77,360
6 people: $88,720
7 people: $100,080
8 people: $111,440

Add $11,360 for each additional person beyond eight. Alaska and Hawaii use higher poverty guidelines, so their income ceilings run higher too.

When agencies verify income, they look at every family member living in the home. Earned income and unemployment compensation for household members under 18 are not counted. If you can only document part of a year’s income, the provider can annualize the partial amount.³

Automatic Qualification Through Other Benefits

You can skip income verification if anyone in your household received cash assistance through Supplemental Security Income (Title XVI of the Social Security Act) or Temporary Assistance for Needy Families (Title IV) at any point during the 12 months before you apply. Note that the rule turns on receiving payments in that window, not on being currently enrolled.¹

Some states also treat qualifying for the Low Income Home Energy Assistance Program (LIHEAP) as meeting the WAP income test, provided the state’s LIHEAP threshold sits at or above 200% of poverty. Whether that shortcut applies depends on the state.¹

Who Gets Priority on the Waitlist

Demand almost always outstrips funding, so agencies rank eligible applicants. Federal rules list five priority categories:⁴

Elderly persons, defined as age 60 or older
Persons with disabilities
Families with children (dependents age 19 or younger, though some states use a lower cutoff)
High residential energy users
Households with a high energy burden, meaning a large share of income goes to utility costs

Falling into more than one category moves you further up the list. The last two matter more than applicants often expect. A single adult spending 15% of income on heat can outrank a larger family spending 5%, because the program is built around cutting energy burden rather than serving the largest households.

Renters and Multi-Family Buildings

You do not have to own your home. Renters qualify on the same income basis as homeowners.⁵

If you rent, your landlord has to sign a written permission form before any work can begin. The landlord also agrees that a rent increase within a “reasonable time period” after the improvements cannot be tied to the weatherization work. The DOE does not fix that period in months; each state or local agency sets and enforces it. Agencies are required to accept and investigate tenant complaints about rent increases that appear connected to the upgrades.⁵⁶

For apartment buildings, at least 66% of units must be occupied by income-eligible households. For duplexes, four-unit buildings, and certain qualifying large multi-family buildings, the threshold drops to 50%. Buildings where non-eligible units will become eligible within 180 days through a government rehabilitation program can also qualify. Once a building meets the occupancy threshold, the whole structure gets upgraded rather than only the units of qualifying tenants.¹

Homes That Won’t Qualify Right Away

A home that has already received WAP services generally cannot get them again. Two exceptions apply: damage from fire, flood, or natural disaster that insurance did not cover, and homes that were only partially weatherized between 1975 and 1993. In those cases, the home gets a new energy audit that accounts for prior work.⁴

Even a first-time home can be deferred if conditions would endanger occupants or crews, or if sealing up the home would make an existing problem worse. Common deferral triggers include:⁷

Unsafe heating systems that cannot be repaired or replaced
Asbestos that has not been remediated by a certified professional
Sewage, mold, or rotting wood, particularly where air sealing would trap contamination indoors
Pest infestations that cannot reasonably be removed
Flammable liquids or chemicals the occupant will not remove
Occupant health conditions that construction activity would put at risk
Refusal of required ventilation equipment
Condemned properties

When a project is deferred, the agency must give you a written notice describing exactly what has to be fixed, including any test results and a statement about when weatherization could resume. Both you and the agency representative sign it.⁸ If the fix is something you can handle on your own, like removing stored chemicals or hiring a pest control company, you can reapply once the condition is resolved.

How to Apply and What to Bring

WAP is administered locally. Start with your state weatherization contact through the DOE directory at the How to Apply page, which links to every state agency. The state site normally lists local providers by county with phone numbers and addresses. Some states accept online applications; most route you to the local agency directly.⁹

Bring documentation of household income for everyone living in the home. Tax returns, pay stubs, and Social Security award letters are the standard proofs. Renters also need the signed landlord permission form. Some agencies ask for utility bills or proof of residency; those requirements are set locally rather than federally.

After you apply, the agency reviews your paperwork, confirms income eligibility, assigns you a priority ranking, and sends written notification of whether you have been accepted, denied, or asked for more information. Waitlists are normal. Timelines run from a few months to over a year depending on your area’s funding and demand, so ask the local provider what to expect. When your name reaches the top, a trained auditor visits your home to assess the heating and cooling equipment, air exchange, and insulation, and that audit determines which improvements the program will fund.¹⁰

What the Program Pays For

WAP takes a whole-house approach. The auditor identifies every cost-effective improvement and ranks them, and each measure has to clear a savings-to-investment ratio test: projected lifetime energy savings must exceed installation cost.¹⁰ That is why an auditor may pass on something you expected to see; if the math does not pencil out, the program will not fund it.

Typical measures include air sealing around windows, doors, plumbing, and ductwork; added or upgraded insulation in attics, walls, and floors; repair or replacement of inefficient or unsafe heating and cooling equipment; water heater and hot water pipe insulation; and efficient lighting. Renewable energy systems such as solar can also be funded, with a separate expenditure limit.¹¹

Certain health and safety items are required regardless of energy impact: working smoke alarms and carbon monoxide alarms placed to fire safety standards, fire extinguishers where needed, and radon precautionary measures such as sealed ground coverings and sump pit covers in homes with basements or crawlspaces. Pure injury-prevention items unrelated to weatherization, like porch boards, exterior lighting, and stair rails, are not covered.¹²

If You’re Denied or Deferred

Every state receiving WAP funding has to maintain a dispute resolution process covering applicant denials, project deferrals, and work quality complaints. Deferred homes are specifically entitled to a deferral appeals process.⁶

Complaints usually start with the local provider. If they cannot be resolved there, they move up to the state weatherization office, and states are expected to offer mediation, arbitration, or a formal state appeal when internal steps fall short. Filing deadlines vary by state, so ask your local agency for the exact timeline when you receive a denial or deferral notice.
