$20,000 none

About the amount

DOE WAP average $8,813/home; separate 'Weatherization Readiness Funds' can go up to a $20,000 average per home to fix blocking conditions (roof, mold). LIHEAP weatherization has no published per-household maximum.

Housing rules

Homeowners and renters qualify; renters need the landlord to sign a CSD form. DOE agreements bar rent increases for 2 years due to the improvements.

How long it takes

Not published by CSD for any stage; Scout's '8-12 weeks' claim is unsourced.

How to apply

Call the CSD call center or use CSD's 'Find Services in Your Area' lookup to find your local agency; no statewide application form number.

Does not pay for

No accessibility mods, general repairs, or property taxes — energy-related work only.
